Founder | Creator | Strategist | Building AI, Leaders, & Ideas That Move Markets

For sponsorships + booking + speaking: hello@cred.marketing
------
I build AI, leaders, products, and ideas that move markets.

As a founder, creator, and strategist, I’ve taken products from concept to market, scaled sales engines, built teams, and created campaigns that drive both revenue and cultural relevance. Deeply integrating AI in every step of the way. 

My experience spans SaaS, AI, B2B, and beyond, working alongside the companies and executives shaping tomorrow’s most important industries. (Would love to work with yours!)

I operate where innovation meets execution. 
Blending the reach of a creator, the precision of a strategist, and the perspective of an AI founder who has built and scaled from the ground up. 

The result: content, campaigns, AI, and go-to-market strategies that cut through the noise and position brands at the forefront of their markets.

Founder

1 month of content in 1 hour

Attended a dinner with top SF founders and VCs.
What top teams are actually betting on for AI in 2026:
(reframed my entire AI roadmap.)

I asked everyone one question:
“One word to describe AI in 2026.”

The answers were telling:
Unpredictable. Essential. Explosive. Pervasive. Vertical agents!

When you zoom out, a few patterns become very clear.

Here’s what actually matters for 2026:

1. AI becomes invisible, but unavoidable
Winning tools aren’t all about the AI AI AI.
AI will just be baked into workflows, decisions, and daily work.

2. Most teams are still using AI wrong
Oh so many teams had shallow AI applications.
And leaned in hard for the branding and buzz words.
Real gains come from deeply integrated systems that compound.

3. Vertical > generic
Vertical agents only win when paired with real domain expertise.
Otherwise, it’s just thin wrappers.
2026 is for AI depth and real applications.

4. Enhancement beats replacement
The strongest founders weren’t chasing “AI replaces X.”
They’re building for human amplification:
better judgment, faster execution, fewer bottlenecks.

5. Humanness becomes a differentiator
As AI gets more powerful, taste, trust, narrative, and leadership are everything!!

If you’re planning for 2026, these are the words I’d build a roadmap around.

Huge thank you to Emma Greenwald, Mahir Kumar Singh, Ricky Marton and the whole HubSpot For Startups team for such an incredibly curated, high-signal room!

everyone is asking how to win on LinkedIn in 2026.
don’t copy the wrong playbook.
copy mine here:

we’re entering the era of AI-generated sameness.
and that’s exactly why founders who sound the most human will stand out.

(thanks Audrey Chia for the great question here!!)

if your content could have been written by a model, it won’t win.
your unfair advantage is your unique, human, point of view.

background. 
lived experience. 
actual opinions from building.

so treat your LinkedIn like a media company.
don’t copy trends, but deliberately do the opposite.

you don’t even need a traditional tech background to do this.
teachers, nurses, operators, founders from any industry all have a lane.

all you have to do is find yours.

be deeply personal. 
unmistakably you.
and build media around that.

that’s how you stand out when everyone else sounds the same.

most founders say they’re “data-driven”.

so why are they still avoiding the hardest decisions?

i teamed up with Alyona Mysko to share with you our top tips for making data work for you, not the other way around. 

ultimately, the problem isn’t lack of data.
it’s lack of decision systems.

data only works when:
1. you know what decision you’re trying to make
2. you’ve set limits before emotions get involved

otherwise it’s just expensive noise.

swipe to see the full breakdown!

Top 2 Tips For Turning Data Into Decisions As a Founder

Come with me for a day in the life!
Building at the center of the B2B creator economy.
(And a sneak peek of what’s next.)

1. Morning at the SF LinkedIn offices.
Unpacking what’s actually coming in 2026!

2. Back-to-back convos with teams building next gen B2B tools.
So fun to hear top insights driving 2026 roadmaps.

3. Burmese lunch between meetings 
(highly underrated, btw)

4. Filming new content, stay tuned!

5. Waymo rides across the city.
Filmed before this week’s Waymo shutdown, lol

6. Closed the day at an invite-only HubSpot for Startups dinner.
Packed with awesome SF founders and operators.

7. And of course, getting to hang w/ the one and only @Katie Wrathall

A few signals I keep hearing from leaders across LinkedIn, HubSpot, and top B2B builders:

- B2B creator economy is shifting from “influencer” to infrastructure
 Content isn’t the output anymore.
Distribution, trust, and repeatable systems are.

- Founder-led media is becoming a core GTM channel.
 Especially on LinkedIn, where credibility compounds.

- 2026 is about depth over volume
Winners go all in on what’s working.

- Lines between product, marketing, and media are collapsing
 The best teams (and creators) are building all 3 together.

Days like this remind me why I’m bullish on where B2B creators are heading next.
And why I’m investing more into behind-the-scenes access, IRL convo, and building in public.

More to come soon in 2026!!
Happy Holidays to you all!

the upgrade you need to your 2026 cold email plans:

(how to basically print meetings!!)

most cold email campaigns fail because emails never land in the inbox.

so i really had to rethink my process here for sending emails.

i switched to Maildoso and my reply rates jumped almost immediately.

here’s why it works:
1. mailboxes are built for deliverability, not just sending. 
2. 98%+ of emails land in the primary inbox (even to outlook)
3. self-healing mailboxes rotate + replace burned addresses automatically, so campaigns never stop.

they also just rolled out Google Workspace accounts. 
so you can get high-deliverability SMTP mailboxes + fully legit workspace inboxes directly inside Maildoso!
(+ they’re priced lower than anything else out there)

plus setup is effortless (no dread!!) 
hundreds of mailboxes ready in mins, domains included, no manual config needed.

and somehow the cost is 50% cheaper than gmail/outlook mailboxes??

if your outbound campaigns feel stuck, this is the playbook you need to hack reply rates at scale.

STOP and do this one thing right now:

(before you adopt any more AI tools)

everyone wants to jump straight to AI.
they buy the latest tools and start running experiments.

but the truth is, AI can only be as good as the data it sees.
without a 𝘀𝗶𝗻𝗴𝗹𝗲 𝘀𝗼𝘂𝗿𝗰𝗲 𝗼𝗳 𝘁𝗿𝘂𝘁𝗵, you get conflicting outputs, misaligned decisions, and wasted time.

a single source of truth is:

 • one place where all data is accurate and up-to-date
 • standardized definitions across teams
 • clear ownership of information

why it matters:

 • AI trained on messy or duplicated data produces unreliable answers
 • teams spend more time cleaning output than using it
 • decisions made from inconsistent data hurt credibility and speed

think of it as the less exciting, but critical, bottleneck to plan for.
(before you start automating or scaling with AI)

the companies who do this first, build reliable workflows and get lasting leverage from AI.

why “AI will replace jobs” is the wrong frame

(+ the reframe that will completely transform your workflows)

everyone keeps asking which jobs AI will replace.
but that’s the wrong question.
AI doesn’t replace 𝘫𝘰𝘣𝘴, it replaces 𝘵𝘢𝘴𝘬𝘴.

every role is a bundle of tasks.
(some routine, some creative, some relational) and AI picks off the routine ones first.

example:
a marketer might spend time writing briefs, analyzing campaigns, pitching ideas.
AI can handle the briefs and analysis.
but the pitching? still so human!!

the better question is:
which tasks in my job are predictable enough for AI to do consistently well?
because that’s where the shift starts.

the future isn’t “AI vs humans”
it’s “humans who redesign their job around AI” vs those who don’t.

Let AI do the heavy lifting for your Revenue.

Your sales team is drowning in manual tasks: prospecting, lead research, CRM hygiene. 
They’re busy, but not productive. And your pipeline shows it.

Every hour wasted on boring and tedious tasks is a deal not closed.
You’re paying top talent to do what AI could handle in seconds. 

Meanwhile, your competitors are already automating and scaling with precision. 
Fall behind, and it’s game over.

TC9 builds AI-powered GTM engines that do the heavy lifting, so your team can focus on closing, not clicking. 

We blend strategy, automation, and intent signals to unlock growth at scale.
No fluff. Just efficiency at every level.

TOP 40 Prompts For Clay In ChatGPT

My lessons from 2025, in no specific order:


→ I like Claude better than ChatGPT now. MCP is just too good.
→ Don't even think of using AI seriously if your data isn't clean.
→ Entrepreneurship is a wild ride (I knew this one since 2023).
→ Authentic content will overtake AI on social media in 2026.
→ A GTM Engine in 2025 was rare. In 2026, it'll be the norm.
→ Remote work is great, regular in-person time is CRUCIAL.
→ Don't try to scale what you haven't mastered. AI or not.
→ Europe is catching up. The French tech scene is rising.
→ You don't need more leads. You need a better system.
→ "How are things doing?" isn't a great prospecting line.
→ AI's biggest challenge isn't tech. It's human adoption.
→ AI was overhyped in 2024. 2025 changed that.
→ Meeting online friends IRL is always amazing.
→ "AI" won't be a buzzword much longer.
→ Still nothing beats a good croissant.
→ Cold email is still not dead.

That's a wrap!

See you in 2026 🙌

Most companies are still overpaying for SDR work.
Work that should run on autopilot.

Manual, repetitive tasks kill momentum. 
They drain budgets and burn out your best people.

I came across an SDR job post from Notion yesterday. 
Even industry leaders are stuck in the old playbook.

Sure, it still works. 
But it won't scale as GTM engines take over.

Here's the contrast:

The old model: 
→ $100k SDRs buried in low-value tasks 
→ Scaling means more headcount 
→ Burnout hits fast when reps see automation gaps

The new model: 
→ Higher output, better quality (no human error) 
→ Reps actually have time to sell 
→ Major cost savings

A custom, automated GTM engine outperforms the old approach. 
It costs less. It runs smoother.

And your competitors are already building theirs.

Stop paying premium salaries for work a machine can do better. 

Move now or get left behind! 


PS: Notion, I'm sure you have solid reasons for that role. But I'd love the chance to challenge them 😄

Even Top Companies Get It Wrong

Most sales teams are running on a treadmill, not building pipeline.

Campaigns are the problem. And it's by design.
You launch, spike, then start over.

In 2026, GTM systems change everything.

Campaigns are time-boxed and resource-heavy.
They spike activity, then vanish completely.

GTM systems do not launch, they live.

Always-on outreach triggered by real signals.
Integrated with your CRM and content engine.

Systems use behavior-driven automated triggers.
Systems self-optimize instead of rebuilding.

Systems reduce rep time significantly.
They work while you sleep, built for ops.

→ Stop saying "Let us launch something this quarter".
→ Start saying "Let us plug this into our GTM engine".

Layer intent signals into your existing flows.

Build the system once.

Let it scale forever!

Ditch Campaigns, Embrace Systems

Stop blaming the channel.
Cold outreach doesn't mean random.

But too many teams treat it that way.
Spray and pray. Mass sequences. Zero context.

Then they wonder why no one replies.

Here's the truth:

You're not ignored because outbound is dead.

You're ignored because "Hi {FirstName}, I see you're in {Industry}" isn't personalization.
It's laziness dressed up as scale.

Prospects know when they're one of 1000.
And they stop reading.

The teams that win do the homework.
They earn attention before asking for time.

Because relevance builds trust.

And trust builds pipeline!

Random Outreach Is Killing Your Business

Clay just dropped a bomb that changes GTM forever.
I'm not sure that you realize how big this is.

Sales research used to mean 6+ open tabs.
Hours wasted on basic account intel.

Clay solves this but has quite a big learning curve.
They lowered the barrier with Sculptor back in September.

But today, this is next level.
Clay now integrates with ChatGPT.

This is MASSIVE.

Here is a snapshot of what you can now get from your favorite chat:

→ Career history and buying signals surface
→ Verified emails and tech stacks included
→ Executive hires and headcount growth
→ Draft contextual outbound in seconds
→ Filter by job start date in one prompt
→ Funding signals and website traffic
→ Find your ideal buyers instantly
→ Get full briefs with contact info
→ Access paywalled GTM data

And these are just the first bricks.

Here's what will come next:

→ CRM and call recordings
→ First-party data

And I can't wait to see it in action with Atlas 🤯

Now, what it really means, in my opinion.

When I asked Varun for a scoop back in Paris, he mentioned something big was coming.

But I didn't expect it to be THAT BIG.

When I was saying that GTM automation will become the new norm in the coming years, people looked at me like I was crazy.

Today I feel like I wasn't that crazy after all.

ChatGPT has 810 million users.
This is mass adoption coming.

GTM automation is the new norm.

Advanced personalization is the new standard.

Your SDRs aren't broken.
The role you designed is.

It's not a skills or tools problem.

You're asking one person to do two jobs.
→ Data engineer by morning.
→ Charismatic seller by afternoon.

That's an impossible ask.

SDRs spend 80% of their day on operations.

→ Spreadsheets
→ Databases
→ CRM

Only 20% goes to actual selling.

These are two opposite skill sets.
You can't flip a switch between them.

Your reps are drowning in your tech stack.

The fix isn't more reps or more tools.

It's splitting the role in two.

Let salespeople focus on conversations.

Bring in a GTM Engineer for the rest.

Someone who automates the operational work.
→ Data enrichment
→ List building
→ CRM updates

That's how you flip the ratio.

From 80% operations to 80% selling.

Your SDRs finally have time to sell.
That's when meetings get booked.

Why Your Sales Team Underperforms

Wondering how Clay crushed it and reached $100M ARR in no time?


Of course, the product is amazing.
That plays a big role in it.

But there are two other factors:

1️⃣ - Marketing

Clay looks like no other company.
Everything, from the logo to their ads, is creative.

Varun mentioned it in Paris: creativity is a core value for them.

First you come up with a crazy idea, then we'll find how it makes sense with business needs.

This is how I ended up rolling joints at a Clay event, I guess!

2️⃣ - Community

Since Day 1 when I started using Clay about 2 years ago, I felt part of something bigger.

I know no other company that could get me so excited that I volunteer to spread the word as a Club Host.

Now, when you see the banger GTM Engineer kit they sent me, you understand why: they care.

Clay's team values their community, and they prove it.

Now you know the recipe to win with your product.

But I'm not so sure if it's replicable!

It's that time of the year. When you think of what you did right or wrong.
One thing I did right for sure is invest in LinkedIn.

LinkedIn is the only social platform that isn't anonymous.
And that changes everything.

Every profile is tied to a real person.
→ Real name
→ Real reputation
→ Real accountability

So people show up differently here.

Lindsay and I started creating content around the same time.

So when she came to Paris → We had to meet!

That's the magic of this platform.
You connect, for real.

Creating content opened doors I never expected:
→ Access to CEOs
→ Friendships with Ruben, Charlie, Adam, Noam, many more.
→ Global travel and collabs

It might sound cliché, but posting built trust before we ever shook hands.

We went from comments to coffee. 
From DMs to dinner tables. 
From online connections to real-life bonds.

LinkedIn isn't just a platform. It's a bridge to the people you actually want to meet.

Clean your list with AI filtering.
Remove competitors and bad fits.

Sales reps just got a superpower inside ChatGPT
And that's how it should be.

Sales teams can now use:
→ Contact databases
→ Enrichment providers
→ AI research agents

Directly from ChatGPT.

What used to require hours and many tools is now happening in one conversation, using the right context.

Here are a few examples of what Clay in ChatGPT can do:

1️⃣ - Find the right people
Filter by role, company, or hiring signal.

2️⃣ - Research prospects and companies
Pull bios, posts, funding, and team changes.

3️⃣ - Enrich contacts and relevant information
Get verified emails, tech stacks, and recent activity.

4️⃣ - Draft personalized outreach
Reference interviews, tech stack, or market shifts.

If you had doubt on how AI could help your Sales team, now you have a clear answer.

It's not about "if" you need AI automation for your B2B growth.
It's about "when" and "how".

2026 will be the year of mass adoption of AI in revenue teams.

Time to jump in!

Hiring more SDRs won't scale your business.
Building a better system will.

Big sales teams are expensive.
And your reps are burning out on repetitive tasks.

You don't need more headcount. You need a GTM Engine.

The old way:
→ 5 SDRs = €30K/month in salaries
→ + €8K/month in tools
→ Result: 20 meetings/month

The new way:
→ 1 GTM Engineer = €7K/month
→ + €2K/month in tools
→ Result: 60+ meetings/month

3x the output. A fraction of the cost.

This isn't a theory. It's what modern sales looks like.

Scale faster. Spend smarter. Close more.

Stop making your team do the boring stuff.

Let AI handle the heavy lifting 💪

Nobody wakes up excited to read your pitch.
But they do pay attention when you make it about them.

Research your prospect. 
Be specific. 
Start a real conversation. 
Earn trust before you ask for anything.

And please: nail the approach manually before you automate it.

Otherwise you're not scaling outreach.

You're scaling noise.

4 metrics killing your sales pipeline.
Time to stop worshipping numbers that lie.

These KPIs look impressive in reports. But they're silently strangling real revenue.

Here's what to watch out for:

→ "Call Volume" in Isolation
More dials ≠ more deals. 
You're tracking effort, not effectiveness.

Reps spam prospects just to hit a number. 
Track instead: Calls that convert to meetings or next steps.

→ "Pipeline Size" Without Substance
A fat pipeline isn't a healthy one. 
Inflated forecasts only delay disappointment.

Reps pad the numbers with dead-end opps. 
Track instead: 3x coverage from qualified, late-stage deals only.

→ "Email Open Rate" as Proof of Interest
Opens stopped meaning anything years ago. 
Bots click. Privacy tools distort. Data deceives.

Reps chase phantom engagement. 
Track instead: Actual replies. Real hand-raisers.

→ "Last Touched Date" as a Pulse Check 
Sending a follow-up doesn't prove life. 
Activity isn't the same as momentum.

Reps keep zombie deals on life support. 
Track instead: Responses, booked calls, buying signals.

Pretty dashboards don't sign contracts. Smart KPIs do. 
Stop rewarding motion. Start rewarding traction.

Ditch the noise. Dial into signal. 
Your pipeline's survival depends on it.

Systems scale. Humans don't. 
But without humans, systems have nothing to scale.

Most GTM strategies are broken.
Reps improvise. Automation spams.

The fix → Know when to use each.

1️⃣ - ICP Targeting & Lead Research 
Humans sharpen positioning and define the market. 
Systems source, filter, and scale your reach.

2️⃣ - Message Strategy & Personalization 
Humans build the story and emotional hooks. 
Systems adapt and distribute them everywhere.

3️⃣ - Outreach Execution 
Humans shape voice and escalation frameworks. 
Systems run multi-channel sequences nonstop.

4️⃣ - CRM Integration & Signal Sync 
Humans architect lifecycle stages and handoffs. 
Systems track replies, update stages, auto-score leads.

5️⃣ - Pipeline Monitoring & Optimization 
Humans analyze, iterate, and develop teams. 
Systems flag friction points and fire workflows.

GTM doesn't work with humans alone. 
It doesn't work with systems alone either.

It works when you split the right tasks at each stage. 

Humans own the signal. 
Systems own the scale.

That's the Human GTM Engine.
