Solving Water at MySutro.com | Forbes 30 Under 30 | TEDx

Water is an underinvested market, yet it’s one of the most crucial resources we have. But I believe that through better storytelling and innovation, we can shine a light on the water industry’s challenges and opportunities. 

In 2014, I founded Sutro, a robotic water diagnostics platform designed to improve water chemistry and safety. I sold Sutro to Sani Marc in 2019 and am currently leading day-to-day operations.

Today, as President of Sutro (a subsidiary of Sani Marc), I oversee the development, marketing, and sales of smart water monitoring devices. Our technology is trusted by some of the biggest brands in the industry, and we are the only NSF-certified autonomous device for water safety. 

I’m proud to lead our team in revolutionizing how people interact with water, ensuring it's clean, safe, and accessible.

The AI Creators’ Club - Jan 5th 2026 | I help you create authentic AI content | DFY LinkedIn growth for leaders | Keynote speaker

✉️ Brand Partnerships / Speaking: charlie@linked-agency.com

Are you struggling to stand out on LinkedIn?

Tired of spending hours crafting content with little return?

It's time to harness the power of AI and skyrocket your LinkedIn presence.

Look, here's the deal:

1. Content creation is the key to LinkedIn success.
2. AI tools can dramatically accelerate your content production.
3. Only a fraction of LinkedIn users are leveraging AI effectively.

Mastering AI-powered content creation is your ticket to dominating LinkedIn in 2025.

The question is, how do you generate enough attention to grow your following and drive results?

Here's what to know.

To start seeing real growth on LinkedIn. You need:

☑︎ A consistent content strategy
☑︎ Engaging, value-driven posts
☑︎ Strategic use of engagement
☑︎ Continuous optimisation
☑︎ Scroll-stopping visuals

This all takes time and expertise.

So you have two options, really:

1. Invest countless hours figuring it out yourself.
2. Learn from someone who's cracked the code.

Either way, I can help you.

I've used AI-powered strategies to grow my own LinkedIn following.

- 50k+ followers in under one year (2024)
- 160k+ followers in 9 months (2025)

Now I help others do the same through:

1:1 Power Hours (DM me “Power”)
↳ Focused strategy sessions

LinkedIn AI Community (DM me “Community”)
↳ Learn + network with peers

Linked Agency DFY (DM me “DFY”)
↳ Done-for-you growth systems

Don't let your content get lost in the LinkedIn void.

Let's leverage AI to create content that converts.

ChatGPT says “Do NOT click the link below”.

Today marks my 28th chapter in life.
Age 26: Broke, insecure, hating my job.
Age 28 (today): I'm where I'm meant to be.

This last year:

1. Grew to 180K followers
2. Built a 6-figure business
3. Spoke on international stages
4. Partnered with top 1% B2B brands
5. Created the life I used to dream about

All because I posted to LinkedIn.

Your dream life isn't waiting for you to be ready.

It's waiting for you to start.

While working that job you hate.
While doubting every single move.
While feeling that fear you can't shake.

What would you build if you started today?

Good "hooks" matter.

The first line of your post = 80% success.

👉 Good hooks have:

1. Specificity:
☒ "Here's how to grow on LinkedIn" 
☑︎ "LinkedIn changed. Your strategy should too."

2 - Engagement:
☒ "AI is changing everything"
☑︎ "ChatGPT changed. Most people didn't notice."

3 - Value Proposition
☒ "Let me share some tips"
☑︎ "I rebuilt my LinkedIn strategy from scratch. (How I went from zero to 115k+ in 494 days)"

4 - Action-Oriented Language
☒ "You might want to try this"
☑︎ "How to make a landing page in 5 minutes. Using AI and your LinkedIn profile."

5 - Relatability
☒ "Here's what I learned"
☑︎ "My AI outputs were trash for 6 months. Then I discovered these 8 prompting styles."

👉 Bad hooks have:

1 - Vagueness: "Pretty interesting topic, right?"
 
2 - Generic Questions: "Looking to grow your following?"
 
3 - Clichéd Openings: "In today's fast-paced world..."
 
4- Tentative Language: "This might work for you..." "
 
5 - Missing Value: "I have a secret to share..."

👉 Hook formulas that work:

Pattern 1: Contrast Reality "Most people [common mistake]. But [tool/method] can help you [better result]."

Pattern 2: Platform Shift "[Platform] has completely changed. The old tactics don't work anymore."

Pattern 3: Personal Discovery "I [tested/discovered/built] [specific thing]. The results: [shocking outcome]."

Pattern 4: Direct How-To "How to [achieve result] in [timeframe]. Using [specific method/tool]."

Pattern 5: Transformation Story "I went from [starting point] to [end point]. Here's exactly how I did it."

I accidentally discovered the future of design.

It's been hiding in Claude's settings this whole time.

You can create stunning LinkedIn carousels using Claude's Skills feature.

This is probably the best AI process for creating on-brand carousels I've come across.

Here's exactly how I turned Claude into my personal carousel designer:

Step 1: Find Your Best Carousel

Pull up a carousel that represents your style perfectly.
↳ Your branding
↳ Your framework
↳ Your tone

This becomes your blueprint.

Step 2: Upload to Claude

Drop that carousel into Claude with this prompt:

"Analyse this carousel and reverse engineer it into a SKILL.md file that captures my content structure, branding, tone, and framework.

Requirements:
1. Start with YAML frontmatter containing ONLY:

   name: skill-name-in-lowercase-with-hyphens
   description: "Description in quotes without apostrophes"

2. Keep the name lowercase with hyphens only
3. Quote the description and avoid apostrophes
4. Save as SKILL.md inside a top-level folder
5. Zip the folder (not the file directly)

Expected deliverable: A single zip file with structure: folder-name/SKILL.md"

Step 3: Upload Your Skill

1. Download the SKILL.md file.
2. Settings → Capabilities → Skills → "Upload skill"
3. Upload the ZIP file.

Your carousel framework is now part of Claude's DNA.

Step 4: Start Creating

Open a new chat. Say:
"Create a LinkedIn carousel brief about [your topic]"

Claude instantly generates:
↳ Slide-by-slide breakdown
↳ Your exact structure
↳ Visual metaphors
↳ Content outline

Step 5: Generate the Carousel

Review the brief. Make tweaks. Then:
"Create the LinkedIn carousel (1080 x 1350 pixel dimensions)"

Claude builds everything:
↳ Your exact colour scheme
↳ Your typography style
↳ Your layout patterns
↳ Your content flow

Step 6: Final Polish

Claude delivers 90% perfection.
Upload to Canva for that final 10%.
↳ Add your signature touches
↳ Tweak alignment
↳ Adjust spacing

From idea to carousel in 15 minutes.

I've tested every carousel creation method.

This beats them all. It's automated but authentic.

LinkedIn Carousels with Claude Skills

Google's AI ecosystem consists of 17+ tools.

I bet you don't know half of them (links below):

No wonder they're dominating the AI race.

Honestly I've probably missed tools here because there's so many. Some don't live to see more than two years - Google Tables is being shut down at the end of this year.

But all of these AI tools are worth exploring, at least trying, providing they match your respective workflow:

THE MODELS

Most of these tools power their stronger Gemini model. Lumiere is baked into Veo 3.1. Vids is baked into NotebookLM.

Smart strategy from Google - deploy these products separately, test them in the wild, then roll them into their core offerings.

They're not just building tools. They're building an ecosystem where each piece strengthens the whole.

ChatGPT Atlas turns LinkedIn into your intelligence layer.

Here's 6 ways I use it (with exact prompts):

Important warning first:

Don't use ChatGPT agent on your LinkedIn.
LinkedIn flags automation (they messaged me).

Atlas is different - it's safe and compliant.

How to run Atlas correctly:

Step 1: Download Atlas
Step 2: Open LinkedIn
Step 3: Be on the right section before prompting

Now, the good stuff...

1. Analyse Your Profile

Ask ChatGPT to break down your About section.
It spots gaps and missed opportunities.

Prompt: “Review my LinkedIn profile, identify gaps, and rewrite my headline for clarity and conversion.”

2. Profile Intelligence

Compares your positioning with top creators.
Shows exactly how to differentiate.

Prompt: "Analyse my LinkedIn profile and tell me how it positions me in the [Insert Niche]."

3. Post Feedback

Grades your post and rewrites weak lines.
Keeps your voice while boosting engagement.

Prompt: "Review my post draft, fix structure and rhythm, and suggest a stronger first line."

4. Engagement Decoder

Maps what hooks and topics get traction.
Reveals what your audience actually wants.

Prompt: "Compare my last 5 posts and show which tone or structure drives the most comments."

5. Prospect Research

ChatGPT quietly killed GPTs.
(They just haven’t said it yet.)

- Everyone built GPTs.
- Published and shared them.
- Waited for monetisation to come.

It never came...

Meanwhile, OpenAI kept quietly upgrading Projects - and nobody noticed.

Here’s what actually changed:

1 → Continuity

GPTs stay frozen after creation.
Static knowledge bases that can’t adapt.

Projects sync with every update.
They retain and reuse context across conversations.

Living workspaces instead of locked tools.

2 → Accuracy

GPTs hallucinate more.
Each chat starts blank, causing accuracy drift.

Projects stay grounded.
Project-only memory keeps facts consistent.
Reduces hallucinations across chats.

3 → File Limits

GPTs max out at 20 files.
You can replace files, but 20 is the cap.

Projects scale with your plan:

- Free users: 5 files
- Plus users: 25 files
- Pro users: 50 files

Upload once, reference forever.

4 → Deep Research

GPTs give one response and stop.
No investigation or synthesis.

Projects run Deep Research mode.
ChatGPT conducts multi-step investigations.
Creates comprehensive reports from many sources.

5 → Auto-Refresh

GPTs don’t update automatically.
Every edit means rebuilding or creating new chats.

Projects sync instantly.
Updates to files or instructions apply everywhere.

6 → Mobile

GPTs barely function on mobile.
They’re desktop-dependent.

Projects work fully on mobile:

- You can update your Project
- You can upload new files
- You can switch models

7 → Sharing

GPTs built their moat on reach.
You can list them on the GPT Store or share via link.

Projects just caught up.
Now you can share full workspaces or single chats securely with your team or clients.

GPTs = public growth.
Projects = private collaboration.

8 → Permissions

GPTs are either private or public.
No control beyond visibility.

Projects add granular permissions.
Invite others with specific chat or edit rights.

9 → Integrations

You can’t use a Project inside a GPT.
But you can use GPTs inside Projects.

This combines custom GPT behaviours with shared memory, files and tools.

Save this. Move your GPTs into Projects.

ChatGPT Projects vs GPTs

I’ve generated 30M+ impressions this year.

Here's the exact 7-step AI process I use daily:

Step 1: The messy notes vault

Every single one of my ideas start raw.
These are random half-thoughts and brain dumps.
Then, I scroll social media (Instagram, LinkedIn, Reddit).

If I see something interesting?
↳ I save it in my notes for later.
↳ Ask: "Why did this blow up?"
↳ Then: "What's my angle?"

Originality = remixing what already works.

Step 2: ChatGPT design briefs

I turn raw ideas into structured briefs.

"Create me a LinkedIn carousel brief."

No fancy prompts. Just context.
I refine until the structure clicks.

Step 3: Notion is my command centre

My design briefs land in my dashboard.
My design team at Linked Agency takes over.
We iterate until it looks viral (before it goes viral).

That's the difference.

Step 4: Stanley writes the caption

Design done. Now the magic happens.

I paste my brief into Stanley (Your Content Coach).
"Write a post in my authentic voice."

Every time I read it back:
"Damn. I'd click that."

That's when you know.

Try it yourself: https://lnkd.in/eqGtRi54

Step 5: The 12/15 rule

Stanley scores every post.
I tweak until it hits 12/15.
Takes 5 minutes max.

Step 6: The anti-algorithm hack

I schedule for 15 minutes after usual posting time.
Then when it's posting time, I hit "Post Now."
This is pure superstition, but it works.

Step 7: Batch creation loop

Morning brain = creative brain.
I batch everything in one sitting.

I repeat this every week day.
Calendar stays a month ahead.

Content shouldn't feel like work.
It should feel like clockwork.

What's your biggest bottleneck?

Save this. Test it tomorrow.

How To Go Viral on LinkedIn

Don't use ChatGPT or Gemini for image generation.

They're actually the worst models to use.

AI images are becoming indistinguishable.
But, you still need to know which model to use.

I tested 8 models with the same prompt:

"Create an ultra-realistic portrait of a brand-new person: a mid-20s woman with cool olive skin, a jet-black chin-length bob with blunt bangs, and hazel eyes framed by soft winged liner and matte charcoal lipstick. She stands in a dim urban corridor with out-of-focus concrete pillars and faint graffiti, wearing a mustard-and-black striped halter top that catches subtle specular highlights. Use a soft key light from camera left and a faint rim from behind to reveal skin pores, tiny peach fuzz, and individual flyaway hairs, with believable subsurface scattering on cheeks and nose. Compose a chest-up shot at eye level, shallow depth of field, creamy bokeh, and natural color grading with gentle film grain. Captured on a Sony A7R IV with an 85mm f/1.8 lens at f/2, ISO 200, 1/200s. Deliver 8K photorealism with editorial-grade lighting, lifelike textures, and magazine-quality depth."

The results (from worst to best):

𝟭. 𝗖𝗵𝗮𝘁𝗚𝗣𝗧 → 7.5/10
Adequate but darker exposure reduces editorial impact.

𝟮. 𝗚𝗼𝗼𝗴𝗹𝗲 𝗚𝗲𝗺𝗶𝗻𝗶 → 7.7/10
Solid editorial quality with correct elements, slightly softer details.

𝟯. 𝗙𝗟𝗨𝗫.𝟭 𝗞𝗼𝗻𝘁𝗲𝘅𝘁 → 7.8/10
Excellent prompt adherence with strong technical execution and convincing textures.

𝟰. 𝗛𝗶𝗴𝗴𝘀𝗳𝗶𝗲𝗹𝗱 → 7.9/10
Competent execution with harder lighting and an ambiguous garment pattern.

𝟱. 𝗜𝗱𝗲𝗼𝗴𝗿𝗮𝗺 → 8.2/10
Good quality but hair colour off and includes unspecified details.

𝟲. 𝗦𝘁𝗮𝗯𝗹𝗲 𝗗𝗶𝗳𝗳𝘂𝘀𝗶𝗼𝗻 → 8.3/10
Good colour palette and corridor atmosphere, but slightly less convincing skin texture.

𝟳. 𝗦𝗲𝗲𝗱𝗿𝗲𝗮𝗺 𝟰.𝟬 → 8.5/10
Clean, professional rendering with good depth and visible skin detail.

𝟴. 𝗠𝗶𝗱𝗷𝗼𝘂𝗿𝗻𝗲𝘆 → 8.8/10
Exceptional photorealism and micro-detail, minor deductions for off-prompt freckles and tight framing.

The models everyone defaults to (ChatGPT, Gemini).

They consistently underperform...

Don't get me wrong.
Gemini is top tier for editing images.

But for one-shot image generations.
Midjourney delivers magazine-quality results.

AI Image Generation Model Guide

I've been testing Gemini 3 since launch.

Here's 3 wild use cases that actually work:

Use Case 1: Dense PDFs into infographics

Every technical document is now a visual asset.
I threw a 34-page white paper at Gemini.

Here's what I did:
↳ Copy entire PDF text
↳ Paste into Gemini
↳ Use this exact prompt:

"Take the following text and transform into a professor whiteboard image with diagrams, arrows, boxes, and captions explaining the core idea visually. Use colors as well."

30 seconds later?
↳ I received a complete whiteboard diagram.
↳ All mapped out like a professor drew it.

Want it social-ready?

Use this prompt: "Make this image 1080x1350 pixel dimensions"

Boom. Perfect for mobile.

Use Case 2: Functional web applications

This shouldn't be possible: "Create an interactive app to test me on my body language when speaking in public."

Gemini built a functioning web app.
↳ Camera feed tracking your movements
↳ Real-time posture analysis
↳ Live feedback graphs

I pushed it further:

1. Enabled "Canvas" mode
2. Used the following prompt:

"Create a stunning 3D visualisation of why the sky is blue."

You can toggle atmosphere, manipulate in 3D.
An AI professor explains the physics in real-time.

Use Case 3: Interactive learning images

Ask Gemini: "Why is the sky blue?"

Forget text explanations.
You get an interactive images.

Click any wavelength:
↳ Infrared shows thermal imaging uses
↳ Visible light explains colour perception
↳ Each click reveals deeper layers

Every element is interactive.
Every interaction teaches something new.

This is how education should work.

I fed 4 AI tools my entire content history.

Now they work like extensions of my brain.

Here's how I use the top 4 AI knowledge tools:

𝗖𝗵𝗮𝘁𝗚𝗣𝗧 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀 → My default brain partner

I dump everything here.

☑︎ Past posts
☑︎ Client briefs
☑︎ Newsletter drafts

It remembers what I've written before.
So I never start from scratch.

It writes like me. Not like AI.

- References my past work automatically
- Maintains my voice across projects
- Connects files, memory, and tools

Ask for LinkedIn advice?
It returns my exact playbook.

𝗡𝗼𝘁𝗲𝗯𝗼𝗼𝗸𝗟𝗠 → My learning lab

Drop in PDFs, transcripts, videos.
It turns them into structured insight.

Not just summaries.
It teaches the material back.

- Audio overviews that actually explain
- Source-grounded responses
- Automatic Q&A and mind maps

Perfect for digesting complex research.
Or turning client calls into actionable briefs.

𝗖𝗹𝗮𝘂𝗱𝗲 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀 → My precision builder

I'm still a ChatGPT daily driver.

But Claude excels at one thing:
Building something specific.

Give it clear guidance.

☑︎ It builds automations
☑︎ Writes creative copy
☑︎ Codes solutions

When I need precision over personality.

Claude delivers.

𝗣𝗲𝗿𝗽𝗹𝗲𝘅𝗶𝘁𝘆 𝗦𝗽𝗮𝗰𝗲𝘀 → My fact-checker

Which AI Knowledge Tool to Choose?

I dissected 50+ high-converting funnels.

10-steps that separates $10k from $1M funnels:

Most funnels fail in the first 3 seconds.

Not because of bad products.
Because they miss the fundamentals.

Justin mapped out what actually works:

Step 1: Hero Banner

Your headline makes ONE promise.
Not three. Not "we do everything."

One transformation they desperately want.

Subheadline reveals your unique vehicle.
How you deliver that promise differently.

CTA should speak to value, not action.
"Get Your Custom Strategy" beats "Click Here."

Step 2: Social Proof Bar

Awards, logos, results, reviews.
Stack your most impressive work.

But here's what most miss:

Specificity beats quantity.
"Featured in Forbes" < "Our Method Featured in Forbes"

Step 3: Audience Call Out

Stop describing demographics.
Start reading their minds.

List their exact thoughts:
↳ "I've tried everything..."
↳ "Nothing seems to work for me..."
↳ "Maybe I'm just not cut out for this..."

Use their language. Not yours.

Step 4: Introduce Your Solution

Don't jump straight to features.
Tease the possibility first.

"There's a new way..."
"What if you could..."
"Imagine having..."

Lead with transformation benefits.
Then highlight what makes you different.

Step 5: Show Expertise

Why should they trust YOU?

Not your credentials.
Your shortcut to their success.

"After helping 500+ founders, I discovered..."
"My 10 years in X taught me this one thing..."

Experience that directly benefits them.

Step 6: Full Offer Stack

3D render everything they get.
Make it tangible, visual and real.

Each element of your offer:
↳ What it is
↳ What it does
↳ Why they need it

Add scarcity and urgency that's genuine.
Not fake timers. Real constraints.

Step 7: Future Pacing

Paint their life after transformation.

Not features. Feelings.
Not process. Outcomes.

"Wake up to..."
"Finally have..."
"Never worry about..."

Sell the destination, not the flight.

Step 8: Testimonials

Full name + title + company.
Video beats text. Text beats nothing.

The more specific, the more believable.
"Increased revenue 47% in 6 weeks" > "Great results!"

Stack them. Overwhelm objections with proof.

Step 9: FAQs

Every unspoken objection lives here.

Accordion-style for skimmability.
SEO keywords for discoverability.

Answer what they're really thinking:

"Is this another..."
"What if I don't have time..."
"How is this different from..."

Step 10: Final CTA + P.S.

Summarise the entire offer in 2 sentences.
Remind them what they're getting.

Big, bold CTA with movement.
Video background or subtle animation.

P.S. adds one final nudge.
Bonus, urgency, or transformation reminder.

That's the anatomy.

Your funnel is your 24/7 salesperson.
Build it right. Watch it convert.

Most people think building AI agents requires coding.

I just built one in 10 minutes with Zapier.

Here's the exact playbook:

Step 1: Set up agent instructions

1. Go to Agents → New Agent
2. Create your prompt with Zapier Copilot

Step 2: Connect your tools

Add the apps your agent needs:

- Data sources (Reddit, RSS, Sheets)
- Notifications (Slack, email)
- Storage (Notion, Airtable)

Step 3: Test your Agent

Click "Test Agent" in the preview window.

Watch your agent come alive:

1. See it process your instructions
2. Watch it connect to your apps
3. Review the output quality

Step 4: Deploy to production:

- Save your agent
- Let it run on its schedule
- Watch it work in the background

Real example I built:

☑︎ Scans Reddit for trending topics
☑︎ Analyses engagement patterns
☑︎ Writes tailored content ideas
☑︎ Saves to Notion automatically
☑︎ Pings me in Slack when it finds gold

Your agent now runs 24/7 in the background.

First run happens immediately.
Then follows your schedule forever.

We're not coding anymore.
We're orchestrating AI agents.

Zapier connects with nearly 8,000 integrations. With that many integrations, your AI agent can run entire workflows without you lifting a finger.

"Vibe coding is only for prototyping." That's a lie.

Here's how people are building real apps:

This month, I built an AI nutrition coach.
(Saving me $240/year in subscription fees)

Built in less than an hour with zero code.

But I'm not the only one.

Real businesses built with Lovable:

Sabrine Matos
Built a women's safety app.
↳ $456k ARR in 3 months

Henrik & Peter
Built an AI content platform
↳ €700k ARR in 7 months

Thana Tharun
Built a gym app as a weekend project
↳ Now serving locals with 100s of users

Describe what you want. Lovable builds it.

The secret is two systems working together:

Lovable Cloud (Backend Engine)
↳ Handles authentication
↳ Manages databases
↳ Scales automatically

Lovable AI (Intelligence Layer)
↳ AI features without setup
↳ Natural language integration
↳ Smart logic built-in

Now it's significantly easier as the hardest parts of building real apps are now handled for you.

Let's say two people get access to Lovable today.

Person A:
↳ Browses the features
↳ Thinks "that's cool"
↳ Never opens it again

Person B:
↳ Describes one small idea
↳ Ships it in 30 minutes
↳ Shows it to 5 people

That's the difference.

Same tools. Same access.
One builds a revenue stream.
One collects another login.

Your move: Be Person B.
Start with your smallest idea.

Without Lovable:
- Great ideas, no execution
- $50k+ developer quotes
- Backend nightmares
- 6-month timelines

With Lovable:
- Deploy instantly
- Idea to app in hours
- Infrastructure handled
- Natural language building

What app will you build with Lovable?

Save this. Build it this weekend.
