Public Funds Bet $22 Billion on ElevenLabs Voice Agents

ElevenLabs closed a $300 million employee stock sale on September 30 that values the London voice-AI company at $22 billion. That price is double the $11 billion mark from its February Series D, and none of the cash goes to the company.

Wellington and T. Rowe Price led the buy. Public-market funds are paying a private-company price for a voice-agent business that still has not listed.

The $300 Million Did Not Hit the Balance Sheet

ElevenLabs said it closed a $300 million employee tender at $22 billion, twice the valuation on its February Series D. In a tender, outside buyers purchase existing shares from staff and current holders. The company does not issue new stock and does not add $300 million to the bank.

Co-founder and chief executive Mati Staniszewski posted the close on X, with Wellington and T. Rowe Price named as leads.

We just closed an employee tender offer which values @ElevenLabs at $22BN, up 2x from our Series D in February. The tender was led by Wellington and T. Rowe Price.

First-time buyers in the sale were EQT, Goldman Sachs, GIC, Ontario Teachers’ Pension Plan, Sapphire Ventures, and BDT & MSD. Returning names included Andreessen Horowitz, Lightspeed, ICONIQ, D.E. Shaw, Evantic, DISRUPTIVE, and Alkeon.

Staniszewski said management also sold a small amount of stock. He has said ElevenLabs is competing for researchers with the largest AI labs, and that secondaries help it stay in that fight. The $22 billion figure is a printed price those labs’ recruiters now have to match in paper, not a fresh war chest for training runs.

Wellington Already Owned the $11 Billion Mark

Wellington is not a new believer. It joined the cap table in May, in the third close of the Sequoia-led Series D, when ElevenLabs said it had surpassed $500 million ARR after ending 2025 at $350 million. Rob Mazzoni, Wellington’s late-stage technology lead, put the firm’s thesis on the record then, four months before Wellington helped lead a doubling of the mark.

Every major enterprise will communicate with its customers and audiences through AI agents. The companies that power natural, human-like interactions at scale will become critical global infrastructure. ElevenLabs has built the technical leadership and commercial traction to define the category, and the company’s growth trajectory reflects the scale of the opportunity ahead.

T. Rowe Price is the other lead. Emma Norchet, speaking for the firm on the September close, pointed at the agent product rather than at raw text-to-speech.

THE BUYERS ON THE $22 BILLION TENDER

• The leads: Wellington and T. Rowe Price set the $22 billion price and headed the $300 million buy.
• New on the cap table: EQT, Goldman Sachs, GIC, OTPP, Sapphire Ventures, and BDT & MSD bought in for the first time.
• Returning funds: Andreessen Horowitz, Lightspeed, ICONIQ, D.E. Shaw, Evantic, DISRUPTIVE, and Alkeon took part again.
• May precedent: Wellington, BlackRock, D.E. Shaw, and Schroders had already come in on the Series D third close with NVIDIA’s NVentures, Santander, and Deutsche Telekom’s T.Capital.

A doubled stamp eight months after a primary round, led by a fund that already held the old mark, is how late-stage AI firms now let public-market money in without an IPO filing. The allocation is scarce. The price is public. The cash stays with sellers.

Fifteen Million Conversations a Week

The operating case the buyers are underwriting is the agent layer, not the original consumer voice clone. Enterprise now accounts for 55% of revenue, the company said, as businesses put ElevenAgents on support, sales, and internal work.

THE AGENT NUMBERS SINCE FEBRUARY

• Weekly volume: Agents handle more than 15 million conversations a week, up 3x since February.
• Agent revenue: ElevenAgents’ ARR has increased more than 3x over the same stretch, a figure the company separated from group ARR.
• Speed claim: A customer analysis found voice agents resolve issues 31% faster than chat agents on average.
• Headcount: The firm now has over 800 people, up from 530 on May 5.

Named rollouts since the Series D include Stripe, Deutsche Telekom, DoorDash’s SevenRooms, insurer Admiral, Customers Bank, Cadence, and the governments of Ukraine and Greece. The company also said its technology runs in daily operations at five of the world’s ten largest tech companies, five of the ten largest insurers, and four of the ten largest telecoms.

Those are company counts, not audited traffic. They are still the numbers a $22 billion buyer has to believe. On the last published group ARR, the new mark is 44 times the $500 million run-rate ElevenLabs said it had already passed by May. September group ARR was not disclosed.

Why Public Funds Are Paying $22 Billion

Staniszewski and co-founder Piotr Dabkowski started the company in 2022 on text-to-speech. The Series D in February was already a pivot pitch: put the $500 million into ElevenAgents, the platform that lets a company deploy agents that listen, answer, and act across phone, chat, and other channels. Andrew Reed of Sequoia joined the board on that round. Total primary capital at that close was $781 million across five rounds.

The September letter goes further. Models now speak, listen, and translate in over 90 languages used by more than 5.5 billion people, the company said. It has packaged vertical agent stacks for financial services, healthcare, government, retail, and telecom, with forward-deployed engineers on site. Since February, the number of companies rolling out multichannel support on the platform has doubled.

As ElevenLabs has grown its conversational agent business, the combination of research, product, and deployment has proved an important structural advantage. The team is able to make improvements at every layer of the stack, allowing them to execute at high velocity and deliver immediate value for its enterprise clients. The rapid growth of ElevenAgents is a testament to this.

That is the bet in one paragraph. Speech is the interface. The product is the full stack sitting on top of it, tuned per industry, billed as software that replaces call-center minutes. If that holds, a voice company can clear a software multiple. If OpenAI, Google, and Meta fold “good enough” voice into the models enterprises already buy, the stack looks like a feature.

Staniszewski put the human case next to the liquidity case: “AI should interact with people the way we interact with each other.” He added that as the company grows, it wants staff to “share in some of the value they are creating for our customers and the wider world.”

Cheaper Voices Keep Pouring Out of Bigger Labs

The same week as the tender, ElevenLabs put Eleven v4 and v4 Turbo into the market, calling them its fastest and most emotive text-to-speech models and saying they lead independent text-to-speech model benchmarks. On September 29 it said Eleven v4 Turbo was live inside ElevenAgents with a median inference latency of about 100 milliseconds. The day before the $22 billion close, it also said ElevenAgents was listed on the OpenAI Marketplace, so OpenAI enterprise customers can give that stack a voice in 90-plus languages against an existing OpenAI commitment.

That listing is the coexistence argument in product form. ElevenLabs is selling the voice and agent layer into the same procurement channel as the lab most able to copy the layer. OpenAI, Google, and Microsoft already sell speech APIs at a wide range of per-character and per-minute rates, some of them well below ElevenLabs’ published premium tiers. The funds leading the tender are betting that enterprises will still pay for the agent wrapping, the vertical tuning, and the voice quality, not for the cheapest waveform.

On September 8 the company named Ethan Tandowsky, formerly CFO of Adyen, as chief financial officer, and Ashley Kramer, who led enterprise sales at OpenAI, as chief revenue officer. The February Series D post already said the firm was building “toward IPO and beyond.” A $300 million secondary at a doubled mark, a public-markets lead set, and a CFO from a listed European fintech is the private-market version of that sentence.

Staff Have Now Sold Shares Three Times

The September sale is the third staff tender in about a year. Each one printed a new price without the company having to raise a primary round at that level.

ELEVENLABS PRICE STAMPS SINCE 2022

From the $9 million first round to $22 billion is four years. From the $11 billion Series D to $22 billion is eight months, 238 days after February 4. Headcount rose by 270 people between the May letter and the September close. On September 30 the company also said it was launching in Belgium. On October 1 Staniszewski said it was opening in the Netherlands.

A doubled mark on a tender, led by funds that already knew the books, keeps early staff paid in cash and keeps the cap table off informal secondary circuits. It also locks a $22 billion reference for the next hire, the next customer contract, and, if the February line holds, the first filing. The $300 million is already in sellers’ accounts. The agents still have to keep the 15 million conversations, and the 3x, moving from here.

Frequently Asked Questions

How Is an Employee Tender Offer Different From a Funding Round?

In a primary funding round the company sells new shares and keeps the cash. In an employee tender, outside investors buy shares that staff and existing holders already own, so the money goes to those sellers. ElevenLabs used that structure on September 30, which is why Goldman Sachs, GIC, and EQT could join the cap table without the company announcing a new primary raise, and why the $300 million does not change the balance sheet the way the $500 million Series D did.

Who Founded ElevenLabs?

Mati Staniszewski and Piotr Dabkowski founded the company in 2022. Staniszewski is chief executive; Dabkowski is co-founder. They are Polish childhood friends who built the first product in London after Staniszewski’s time as a Palantir deployment strategist and Dabkowski’s work as a machine-learning engineer at Google. The first round, announced with the Eleven v1 speech model, valued the company at $9 million.

What Is ElevenAgents?

ElevenAgents is the company’s platform for putting voice and chat agents into live customer and employee workflows, with integrations, testing, and monitoring aimed at large operations. It is separate from ElevenCreative, the studio tools for making and localizing audio, and from ElevenAPI, the developer speech interface. The company says customer journeys on the platform can start on WhatsApp, move to a phone call, and finish in email, and that it ships industry-specific agent kits rather than a single generic bot.

How Much Primary Capital Has ElevenLabs Raised?

As of the February 4, 2026 Series D, ElevenLabs said total funding was $781 million across five rounds, including the $500 million Sequoia-led D itself. The May third close added more primary capital from names such as BlackRock, Wellington, NVIDIA’s NVentures, and Deutsche Telekom’s T.Capital, but the company did not publish a new cumulative total on that post. The $100 million and $300 million tenders sit on top of that primary stack and are not additions to it.
