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

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.

What’s the Point of a Long Life If It’s Not a Fulfilling One?

Most people chase longevity like it’s the ultimate goal. Longer life, better health, more years on the clock.

But what if living longer isn’t enough?

I’m Dr. Felix Bertram, a dermatologist turned entrepreneur, and I once discovered that biologically, I was already at retirement age.

That realisation forced me to rethink everything. Longevity isn’t just about adding years. It’s about adding meaning, purpose, and connection.

What I Share
- Growth and Development – How to continuously evolve, no matter your age
- Relationships – The key to a long life isn’t just health, it’s who you share it with
- Longevity with Purpose – Why living longer only matters if it makes life richer

Failure is part of the journey.

Many people won't make it past the first step.

I never liked the word "failure."
It makes everything sound final.

And in my experience, most things that people call "failures" are simply part of their journey.

When you're working towards your dreams, 
it's rare that things go right the first time.

You try something, it doesn't work as you hoped, and you learn from it for the future.

The pattern is always the same:

You fall.
↓
You accept that something went wrong.
↓
You find the root cause of the problem.
↓
You search for the lesson in the issue.
↓
You piece together what's needed next.
↓
You come up with a new plan with this knowledge.
↓
You reach the other side better than before.

The only real failure is giving up on your goal completely.

And every lesson you gain from setbacks makes you stronger in the long run.

What recent setback taught you something useful?
