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.

The playbook I use to see trends early:

(my unfair advantage going into 2026)

I’ve led top brand campaigns w/ some of the coolest companies.
And right now, I’m deep in planning mode for what’s next.

A huge focus for me is spotting where trends actually start.
Then plugging campaigns into those moments.
Cutting in while people are still deciding.

Cause this messy middle (where Q’s repeat, opinions clash, community hangs) is where the real signal lives.

That’s why Reddit for Business is ranking at the top for me right now.
I use Reddit to:

- uncover golden audience insight from authentic convos
- activate audiences before they’ve made up their minds
- carry signal all the way through the funnel without losing trust

One example: I used Reddit Pro keyword tracking to spot a pattern forming across multiple communities. That signal showed up weeks before it appeared on other platforms.

We shaped the campaign around that language. Message landed immediately. Performance followed.

My 2026 system looks like this:
listen first → identify repeated intent → shape the narrative → then distribute.

The real edge now isn’t louder marketing. It’s understanding people earlier andddd meeting them while they’re already deciding.

That’s the playbook I’m building around.

Reddit is such an unfair advantage.

feeling overwhelmed with content for 2026?

it might not be a content problem
but an AI tool stack problem.

too many tools, tabs, workflows would drive anyone crazy.

more AI hasn’t made content better.
it’s made it heavier.

the best creators I know aren’t running massive stacks.
they’re using 4 tools max.

because fewer decisions means more brain space saved.

here’s the stack to simplify your workflows:

𝟭. 𝗼𝗻𝗲 𝘁𝗵𝗶𝗻𝗸𝗶𝗻𝗴 𝗽𝗮𝗿𝘁𝗻𝗲𝗿
something to help you pressure-test ideas, structure thoughts, sharpen voice, get unstuck.

𝟮. 𝗼𝗻𝗲 𝘄𝗿𝗶𝘁𝗶𝗻𝗴 𝗼𝗿 𝗲𝗱𝗶𝘁𝗶𝗻𝗴 𝘁𝗼𝗼𝗹
used sparingly for clarity and flow.

𝟯. 𝗼𝗻𝗲 𝘀𝘆𝘀𝘁𝗲𝗺 𝗳𝗼𝗿 𝗰𝗮𝗽𝘁𝘂𝗿𝗶𝗻𝗴 𝗶𝗱𝗲𝗮𝘀
catch thoughts fast!

𝟰. 𝗼𝗻𝗲 𝗽𝗹𝗮𝗻𝗻𝗶𝗻𝗴 𝘀𝘆𝘀𝘁𝗲𝗺
a calendar, checklist, or light scheduler to help you stay consistent + intentional.

that’s it.
everything else is complexity disguised as productivity.

AI should reduce friction, not add it.

if your stack feels heavy, that’s the signal.
simplify!!

how to prevent scaling the wrong ideas:

(despite what AI tells you!)

AI is making bad ideas scale faster than ever.
but the problem isn’t AI’s.
it’s us hitting publish too fast.

something sloppy, half-baked, or just wrong can now reach hundreds, thousands, even millions, before anyone notices.

so how do you avoid amplifying mistakes?

pressure-test your thinking first.

here’s how:
1. slow it down
don’t hit publish right after generating a post.
take a breath. review. reconsider.

2. read it out loud
does it sound like you?
does it convey what you actually mean?

3. flip perspectives
what would a critic say? 
what would someone outside your industry think?
(critics aren’t the end-all, but can be worthy of thought)

4. share with another human
even one person spotting a gap can save you a lot of trouble.

your job isn’t to make more content.
it’s to make better content.

slow down.
pressure-test.
then scale.

I’m revealing my 3 layer storytelling strategy:

(copy my hack for better, more human outputs!!)

AI can generate words, but it can’t automatically tell your story the way your brand does.

to get consistent, on-brand output, teach the model your narrative in 𝟯 𝗹𝗮𝘆𝗲𝗿𝘀:

𝟭. 𝗰𝗼𝗿𝗲 𝗯𝗲𝗹𝗶𝗲𝗳𝘀
define the principles your brand stands for.

 • write 2-3 sentences describing your values.
 • prompt AI: “use these beliefs as the foundation for all messaging”
   example: “we believe marketing should build trust, not just clicks”

𝟮. 𝘀𝗶𝗴𝗻𝗮𝘁𝘂𝗿𝗲 𝗲𝘅𝗮𝗺𝗽𝗹𝗲𝘀
collect stories, case studies, or examples that capture your voice.

 • list 3-5 recurring stories or wins.
 • prompt AI: “reference these examples to illustrate points naturally”
   example: “highlight how brands scale with AI while keeping human creativity central”

𝟯. 𝘀𝗵𝗮𝗿𝗲𝗱 𝗹𝗮𝗻𝗴𝘂𝗮𝗴𝗲
document recurring phrases, terminology, and tone.

 • compile 5-10 phrases or words you always use.
 • prompt AI: “write content using this tone, language, and style consistently.”
   example: “always lowercase, concise, educational, with punchy takeaways”

𝗵𝗼𝘄 𝘁𝗼 𝘂𝘀𝗲:

 1. feed all three layers to the model before generating content
 2. ask AI to produce the first draft
 3. review, tweak, and add new examples to refine outputs

the better you teach, the less editing you need.
and AI becomes a true storytelling partner.

everyone’s asking how to use AI for content in 2026.
but that’s not really the question.
the real advantage is knowing what AI can’t do.

AI can generate ideas but it can’t live the moment that led to them.

AI can summarize what happened but it can’t show the tension while it was happening.

AI can clean up copy but it can’t recreate the back-and-forth, the second guessing, the almost wrong call.

that gap is where the human opportunity is.
in 2026, the content that actually works will be more real.
really, truly, real.

what to share instead of generic AI content:
• the decision you went back and forth on
• the thing that didn’t work + why
• what surprised you this week
• how something actually got approved
• what you changed after seeing real results
• the part of the process you normally skip over
• your real personality and human-ness

so show the tradeoffs, constraints, the imperfect execution.
what makes us truly humans, all giving our best go at this.

bc people don’t trust you because you sound smart.
they trust you because they understand how you think.

AI will keep raising the baseline.
but ultimately humans still win on depth and being real.

Redefining what it means to live longer with purpose | Shark Tank investor and Entrepreneur | TEDx speaker

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

My Journey

I believe true longevity isn’t just about extending life. It’s about making every moment count.

If you’re ready to rethink what it means to grow, thrive, and live fully, let’s connect.

Your dreams feel far away right now...

But next year, they'll be your reality.

Thank you Lise Kuecker for this image.

That gap between where you are now and where you want to be can feel uncomfortable.

Especially when progress isn't obvious at first.

In my own journey, I've had to rethink plans more than once.

Life went in a different direction.
Original plans didn't go as expected.
Or I learnt something that would be better for me in the long run.

I felt this lesson when I realised my health had taken a back seat for years.

That moment forced me to look to the future and choose a different path.

I had to change bad habits that became my normal.
Let go of what wasn't working for me.
And build a different future for myself.

In the beginning, everything felt frustrating and slow.

I felt like I wasn't making any progress.

But that's exactly how growth works.

When something is new, your brain is adjusting to new patterns.

Everything takes more effort.
And that slow period means that learning is happening.

If you're trying something new, and improving your life,
this is what worked for me:

Track your progress.

You don't need to make it complicated with a fancy spreadsheet.

Even writing down what you learned that day in a notebook can stop the idea that nothing is happening.

Soon, you'll notice how you've improved after a week, then a month.
And before long, you'll see how much ground you've covered.

If you're in the stage where things feel harder than they should,
pause before you judge yourself.

You've overcome challenges before.

This is just another chapter asking you to grow.

What's something you're working on right now?

Redefining what it means to live longer with purpose | Shark Tank investor and Entrepreneur | TEDx speaker | Author

Not all dopamine is good for you.

You have to get it from the right places.

Most people spend their days chasing the wrong type of dopamine.
It's the short rush of joy we get when we scroll or have a quick snack.

And yes, it feels good in the moment.

But once it fades, you're either looking for the next quick boost,
or you're lethargic for the rest of the day.

The dopamine that actually supports your energy works differently.

It builds up slowly, lasts longer,
and is tied to very simple actions:

✅ Get natural sunlight in the morning.
✅ Take a 30-minute walk.
✅ Finish your shower with cold water.
✅ Listen to music.
✅ Finish a difficult task.
✅ Write down your goals to stay accountable.
✅ Spend some time in nature.
✅ Help someone without asking for anything in return.
✅ Finish a workout.

These habits don't overwhelm your brain.
They steady it.

Over time, you learn to associate motivation with activities that support good dopamine.
And that helps boost your health, work and life.

You don't need extremes or detoxes.
You just need small choices that feel good now, and still feel good later.

If you want more energy in your day, start there.

What's one good habit that you stick to daily?

People are already giving up on their New Year's goals.

Are you going to be one of them?

This is the point where most people stop.

→ The excitement of a new goal has disappeared.
→ Progress feels slower than you expected.
→ Old habits start to look appealing again.

Every successful person goes through this phase.

What sets them apart from everyone else is that they don't give up.

Growth rarely jumps straight from comfort to confidence.

You have to go through all the stages:

Comfort Zone:
↳ This is familiar, predictable, and safe. 
↳ Nothing changes here.

Fear Zone:
↳ Self-doubt is loudest here. It feels easier to give up.
↳ This is when many people go back to the comfort zone.

Learning Zone:
↳ This is where you start building up more confidence. 
↳ Mistakes don't sting as much, and you start to develop.

Growth Zone:
↳ Everything feels easier because you've put in the work.
↳ Your goals become more ambitious, and you know you can achieve them.

If you feel uncomfortable now, it doesn't mean you're failing.
It means you're exactly where you're meant to be.

A few simple things can move you through the fear zone:

→ Keep your goals somewhere you can see every day.
→ Never miss two days in a row, even if the effort is small.
→ Focus on progress, not perfection.

You can make a lot of progress by staying consistent.

Wherever you are in the growth process, keep going.
