The Founders
Two high-school friends from Warsaw.
One from Palantir. One from Google's machine learning team.

Mati Staniszewski and Piotr Dabkowski grew up together in Poland. They bonded over a shared frustration: watching badly dubbed Hollywood films where the voices never matched the actors. It sounds trivial. It wasn't. That frustration became the founding insight for an $11 billion company.

But the founding insight alone wouldn't have raised a single dollar. What mattered at pre-seed was who they were when they walked into those meetings.

Mati had worked at Palantir, one of the most selective hiring bars in tech. Piotr was a machine learning engineer at Google, working on the exact technical domain they were building in. These aren't just good CVs. They're signal. At pre-seed, when you have no revenue and no product in market, your credentials are the entire risk assessment.

The Insider Take Gian Seehra
At pre-seed, investors aren't evaluating your product. They're evaluating whether you're the kind of person who can build one. Ex-Palantir and ex-Google ML is about as strong a credential signal as you can send in AI. It doesn't guarantee the round closes, but it gets you in the room. Most founders underestimate how much their background does or doesn't do for them at this stage.

The Pre-Seed, $2M That Almost Didn't Happen
Even with those credentials,
they struggled to close $2M.

ElevenLabs was founded in April 2022. By January 2023, they'd raised a $2M pre-seed from Credo Ventures and Concept Ventures. On paper that sounds clean. In reality, it was a grind.

Two Polish founders, no US network, building in a space, AI voice synthesis, that most investors in early 2022 still considered niche. Remember: ChatGPT hadn't launched yet. The AI hype cycle hadn't started. They were pitching voice AI to investors who didn't yet believe AI was a platform shift.

$2M Pre-seed raised
Apr 2022 Founded
~8 People at launch

The pre-seed closed with two European VCs. Not a16z. Not Sequoia. Not any of the names that would show up later. That's normal. And that's the part of this story most founders need to hear.

Gian Seehra
The Insider Take Gian Seehra
This is the thing that founders raising right now need to understand. A company that went on to be valued at $11 billion had trouble raising $2M. That's not unusual, it's the rule. Every single company, even the ones that become generational, gets rejected at the earliest stages. It doesn't mean your company is bad. It means pre-seed is hard for everyone. What separates the ones that make it is volume and process, getting in front of as many investors as possible and running a structured outreach operation, not waiting for warm intros that never come.

The 12 Months That Changed Everything
They didn't spend the next year fundraising.
They spent it building.

After closing the pre-seed, Mati and Piotr made a decision that most first-time founders get wrong. They didn't immediately start working on the Series A. They didn't split their time between investor meetings and product work. They went heads-down and built.

For roughly 12 months, the entire team, about 8 people, focused on one thing: making the voice synthesis models as good as they could possibly be. No press tours. No conference circuits. No premature fundraising conversations.

Then, in January 2023, they launched a public beta. And the internet found them.

Apr 2022

Jun 2023
$19M Series A. a16z leads. Nat Friedman. Daniel Gross. The biggest names in AI investing. Just 5 months after the beta launched.
Gian Seehra
The Insider Take Gian Seehra
This is where most founders go wrong. They close the pre-seed and immediately start thinking about the next round. They split their attention between building and fundraising, and neither gets done properly. Mati and Piotr didn't do that. They put their entire focus into making the product undeniable, and then the product created the next round for them. The viral moment wasn't luck. It was the result of having something so good that people couldn't stop talking about it. You can't manufacture that if you're spending half your time in investor meetings.

The Series A, When a16z Came Calling
They didn't pitch a16z.
a16z came to them.

By mid-2023, ElevenLabs wasn't looking for investors. Investors were looking for ElevenLabs. The product had gone viral. The user growth was exponential. And the angel list that materialised reads like a who's-who of tech:

a16z Lead investor
$19M Series A
$100M Valuation
5 months After beta launch

Nat Friedman (former GitHub CEO), Daniel Gross (Y Combinator partner, AI investor), Mike Krieger (Instagram co-founder), Brendan Iribe (Oculus co-founder), Mustafa Suleyman (DeepMind co-founder). These aren't cheque-writers. These are the people who built the platforms the last generation ran on.

When your angel list looks like that, every VC in the market pays attention. Not because of the money, $19M is a normal Series A. Because of what those names signal: the smartest people in AI looked at this company and decided to put their personal capital in.

The Series A wasn't a fundraise. It was a competitive process created by product-market fit so obvious that the biggest names in tech fought to get in.

The Acceleration, $80M to $500M
From unicorn to $11 billion
in twenty-five months.

Once the Series A closed, ElevenLabs entered a different phase. The early-stage grind was over. What followed was pure execution and scale.

Jan 2024, Series B: $80M
Valued at $1.1 billion. Unicorn status. Just 7 months after the Series A. Revenue went from effectively zero in early 2023 to an estimated $80–90M ARR. Team grew from 8 to ~40 people.
Jan 2025, Series C: $180M
Valued at $3.3 billion. 3× valuation jump in 12 months. The product had expanded from voice synthesis to a full audio AI platform, text-to-speech, voice cloning, dubbing, sound effects.
Feb 2026, Series D: $500M
Sequoia leads. $11 billion valuation. Total funding: $781M. IPO reportedly on the table. From struggling to raise $2M to one of the most valuable private AI companies on earth.
11× Valuation jump, A to B
$781M Total raised
~4 yrs Founded to $11B

The later rounds are impressive. But they're not where the real lessons are. By the time you're raising a Series B at a billion-dollar valuation, the fundraise is driven by numbers, not narrative. The decisions that created this outcome were all made in the first 18 months.

What Most Founders Miss

If 100 founders studied this story and tried to extract the lessons, here are the three things most of them would get wrong.

01
They'd think the viral moment was luck
It wasn't. The product went viral because it was genuinely better than anything else available. That didn't happen by accident, it happened because the founders spent 12 months in stealth making the models as good as possible before showing them to anyone. Virality is a consequence of product quality, not a marketing strategy.
02
They'd try to fundraise and build at the same time
After the pre-seed, Mati and Piotr didn't split their focus. They didn't do the thing most founders do, one foot in investor meetings, one foot in the product. They went heads-down building. The product created the demand for the next round. If you're spending half your time fundraising and half building, you're probably doing both badly.
03
They'd assume the pre-seed was easy because of the $11B outcome
It wasn't. Two Polish founders with no US network, raising in 2022 before the AI hype cycle, in a niche that most VCs didn't understand. They got rejected. A lot. Every great company does at the earliest stage. The difference is they kept going, ran a volume-based process, and eventually found the investors who got it. That's the entire game at pre-seed.
7
The Full Journey, $2M to $11B
Every round built on the one before it.
But the early decisions determined all of it.
Apr 2022, Founded
Mati Staniszewski (ex-Palantir) and Piotr Dabkowski (ex-Google ML) start ElevenLabs. Inspired by badly dubbed Polish movies. Small team, no external noise, fully focused on building voice synthesis models.
Jan 2023, Pre-Seed: $2M
Credo Ventures and Concept Ventures. Two European VCs. Not the big names. Not the Silicon Valley tier-1s. The hardest money they'd ever raise, and the money that made everything else possible. Beta launches the same month.
Jan–May 2023, The Viral Moment
1 million users in 5 months. 4chan deepfakes, Harry Potter x Balenciaga, celebrity voice clones everywhere. The product explodes. Every AI investor in the world is now watching.
Jun 2023, Series A: $19M
a16z leads at $100M valuation. Nat Friedman, Daniel Gross, Mike Krieger, Brendan Iribe, Mustafa Suleyman, all in. The biggest names in tech, in one round. 5 months from beta to a16z.
Jan 2024, Series B: $80M
$1.1B valuation. Unicorn. 11× valuation increase in 7 months. Revenue went from near-zero to tens of millions. Team grew from 8 to ~40. The model expanded, voice cloning, dubbing, sound effects.
Jan 2025, Series C: $180M
$3.3B valuation. Full audio AI platform. Enterprise customers. The voice that powers thousands of apps and creators worldwide.
Feb 2026, Series D: $500M
Sequoia leads. $11B valuation. $781M total raised. IPO reportedly in sight. From two friends who couldn't get a meeting in 2022 to one of the most valuable private AI companies on the planet.
Gian Seehra
The Insider Take Gian Seehra
The $11B valuation is the headline. But the real story is what happened between April 2022 and June 2023. Two founders who had the credentials to get meetings, the discipline to focus on building instead of fundraising, and the persistence to keep going through rejection at pre-seed. The product they built during that period created everything that came after, the virality, the a16z round, the unicorn status. Every round after the Series A was earned by the decisions they made in the first 14 months. That's where your raise is won or lost too.
The Takeaway

ElevenLabs didn't raise $781M because they were in the right place at the right time.

They raised because two founders with strong credentials went heads-down building for a year, created a product so good it went viral on its own, and then let the traction do the fundraising for them. The early rounds were hard. The later rounds were inevitable, because of what they did when nobody was watching.

Your raise works the same way. The question isn't whether you can replicate the $11B outcome. It's whether you're making the same early-stage decisions, focusing on building something undeniable, running a volume-based process when you have no leverage, and not splitting your attention between fundraising and the product.
