Founder @ Stealth AI |TechStars AI Startup Weekend SF

I'm an entrepreneur with experience in banking, investments, and tech. I've been both an investor and a founder. Passionate about tech, AI, physics, math, cosmology, and history, I hold a master's in international economics and management from Kyiv National Economics University. I believe accelerating AI is critical to humanity's prosperity.

As the founder of OpenBabylon, I’m building the post-training stack for real-world AI adaptation & sovereign AI models. I focus on making AI deployable, efficient, and aligned by driving strategic partnerships, revenue growth, and enterprise adoption. Our work enables enterprises and governments to optimize AI performance, cut costs, and scale deployment across diverse markets.

Previously, as CEO of Party.Space, a B2B virtual events platform, I navigated pivots and secured partnerships with Google, Zapier, Grammarly, UC Berkeley, and Fortune 500 companies, raising over $2M from top European VCs and angels.

I advise several early-stage companies on fundraising, zero-to-one hustle, and go-to-market strategies. My understanding of AI technologies and trends helps these companies shape and implement their strategies.

Known for my lively personality and ability to build connections, I enjoy mentoring aspiring entrepreneurs and sharing my experiences. My goal is to keep learning, explore new possibilities, and create a lasting impact through technology and innovation.

Saw a man eating soup at a Vietnamese market.

He didn't look up from his bowl once.

I thought: "This man understands focus."

Asked what he does. "GPUs," he said.

"Pho cures bubble hangovers," he added, unprompted.

Finished eating. Put chopsticks in leather jacket pocket. Didn't tip. Left.

His company is worth $4.4T.

3 lessons for startup founders:
→ Soup > Slack 
→ Street stalls > WeWork 
→ $3 meals, $65B quarters

While you were posting about Nvidia earnings, Jensen was already eating breakfast thinking about 2026.

That's the difference.

Okay everyone, please disregard my AI bubble posts from last week. We are so back!
/sarcasm off
For real though: Nvidia just reported $57B revenue. Beat by $2.4B. Q4 guidance: $65B.
Jensen: Blackwell sales "off the charts."
The bubble is real. The infrastructure is getting built. Both things are true.

Cheers to that, Mr. Huang🍸

Yeah you probably know me as the guy who started Party.Space from a cold email to Spotify.

Thought I had B2B sales figured out. Then I met  Alex Lugosch and Ilya Druzhnikov and they showed me what I was missing. The phone. 

We've done 15+ sessions together calling C-level execs at $100M+ mid-market and enterprise companies. 7am cold calls. Catching decision-makers before their calendar fills up.

The insights were pivotal for our new product direction at OpenBabylon. 

Hearing exactly why someone doesn't want your product -- in real time -- beats months of surveys and LinkedIn messages.

These guys are hosting a live cold-calling session tomorrow at European Startup Embassy (hidden gem of European culture in SF btw -  props to Luca Stirbat 🌀). They'll pitch founder products to real decision-makers while you watch.

If you want to learn how to actually talk to customers -- not send another email sequence -- this is it.

Tag your B2B founder friend or send them the link in comments 👇

This post will make your AI founder friend wake up at night.

Especially if they didn't raise their sweet $50M seed round yet.

PitchBook just dropped 5 charts on the AI bubble debate. The numbers:
45% of fund managers say AI bubble is the biggest tail risk to markets. Up 12 points from last month.

For the first time since 2005, majority of investors say companies are overinvesting in capex.

$5 trillion required for AI infrastructure buildout. $1.4 trillion funding gap.

Hyperscaler CapEx tripled since end of 2023.

Late-stage AI valuations back to 2021 ZIRP-era levels.

Any fool makes money in a growing market. The real test is what you build for the falling one.

When the correction hits, CFOs will ask one question: "What's the ROI?"

Products that survive: 
→ Cost reduction (not growth acceleration) 
→ Decision-making under uncertainty 
→ Proving unit economics in 90 days 
→ Doing more with less compute

Products that don't: 
→ AI wrappers with no moat (except for AI GFs) 
→ "We'll figure out monetization later" 
→ Anything that needs 18 months to show value

At OpenBabylon, we're building AI for corporate strategy and decision-making. The kind of tool that becomes more valuable when markets get uncertain -- not less.

The bubble will pop. The infrastructure will remain. The question is whether your product is infrastructure or foam.

Tag a founder who needs to see this.

Senior UI/UX Designer @ Toptal | Prototyping, Branding, UI Development

I am a Senior UI/UX Designer at Toptal, a network of the world's top 3% of software engineering, design, and finance talent. With over 10 years of experience in the design industry, I have a proven track record of creating visually engaging and user-friendly interfaces for in-car navigation systems, SaaS apps, and marketing websites.

My background in business and economics gives me a unique perspective on how to design UX and UI that are not only aesthetically pleasing, but also functional, efficient, and user-friendly. I am passionate about solving complex problems, collaborating with diverse teams, and learning new skills. I am also Adwords Search Certified, which demonstrates my ability to optimize the online presence and performance of my clients. My goal is to help tech companies increase their revenue by improving the user experience of their products.

Senior UI/UX Desiger

A lead designer once told me, “We don’t have time for UX research.”

I said, “Then you’ll make time for rework.”

Because that’s the tradeoff.

If you skip qualitative research, your next sprint will be filled with fixes.
If you skip quantitative research, your next decision will be based on vibes.

I’ve seen this mistakes with every single design team I’ve worked with. 

Zero exceptions. 
Myself included.

Here’s the cycle that works:

Qualitative → Design → Quantitative → Refine.
Talk → Build → Measure → Repeat.

Let me explain:

Qualitative research makes people care.
Quantitative research makes people act.

Together? They make decisions make sense

Through numbers, you measure behavior.
Through stories, you understand it.

My process allows me to:

1. Design with confidence, not assumptions
2. Balance empathy with research evidence
3. Build products users actually want

Every great product you admire was built this way.

Skip a step and you’ll build twice.

(Repost ♻️ if this hits home.)

P.S. Which step do you usually skip first talking or testing?

Senior UI/UX Product Designer | UX Strategy | Figma

I once told a junior designer:

“You are better than me.”

She froze.
Then shook her head.

But I meant it.

Her instincts fast.
Her ideas were fresh.
Her courage fearless.

We spend so much time chasing recognition that we forget how powerful respect can be.

Better designers don’t diminish you.
They define what’s next for you.

When you respect greatness without envy, you create room for your own.

Respect over recognition. Always.

P.S. Who’s one designer you quietly respect more than anyone else? Tag them.

If I could go back 10 years…

I wouldn’t change the tools I used.
I wouldn’t change my niche.
I wouldn’t change my style.

Instead?

I’d only change one thing.
I’d start designing badly… sooner.

Because every “ugly” design, every failed concept, every 3-hour layout that still looked wrong…all of it built the instinct I have now.

That instinct?
It’s why I can deliver a clean result in 20 minutes today.

The minutes are visible.
The decade is invisible.

And that’s the part that matters most.

Stop trying to be perfect.
Start trying to build your years.

Because once your decade is strong…
your 20-minute magic becomes inevitable.

(Repost if you wish you started earlier ♻️)

P.S. What’s the earliest design software you ever used?

I rarely write posts like this. (Please read.)

Because this one… hits deep.

There’s a quiet suffering in the design industry nobody talks about enough.

Designers with years of practice… still feeling invisible.
Designers with real talent… still apologizing for their prices.
Designers with serious skill… still losing work to “someone cheaper.”
Designers who give everything… still fighting imposter syndrome daily.
Designers with burning ambition… still wondering if they’ll ever be seen.

Let me keep this short:

If you’re a designer, feeling undervalued right now you’re not alone. 
Every good designer has been there.

If you’ve ever questioned your worth you’re also not alone. 
Every great designer questions themselves.

If you’re silently hurting because your talent isn’t seen please know: 
the world is full of clients who will see you.

The pain is real. But it is not permanent.

You’re building a career people don’t understand…
until they desperately need you.

Stick around. Your breakthrough is coming.

(Repost if someone needs this reminder ♻️)

P.S. Leave a comment not for engagement, but for solidarity.

Every designer eventually realizes this:

You don’t need more tools.
You don’t need more plugins.
You don’t need more fancy software.

You need a better eye.

And your eye is shaped by principles of design.
Not by features.

Once I understood that, everything changed:

• My work finally had rhythm
• Spacing started to make sense
• Visual decisions became intentional
• Layouts stopped feeling “accidental”

And suddenly… my work looked cleaner without adding anything new

The day I stopped chasing trends and started studying why designs work…
Was the day my growth finally clicked.

Your career changes the moment you stop decorating
and start designing with principles.

P.S. Did you have a moment when design suddenly started making sense?
