Rejected by 180 investors, Bland just raised $50M to prove voice AI is the future

Isaiah Granet spent three weeks at Y Combinator getting turned down by 180 investors. Their reason was always the same: phone calls would not exist in a year. He has now raised more than $100mn to prove them wrong.

His startup, Bland, has closed a $50mn Series C led by Dell Technologies Capital, Fortune reported. HubSpot Ventures, Archerman and Tribeca joined, along with existing backers including Emergence Capital, Upfront Ventures, Scale Venture Partners and Y Combinator.

The angel list is a who’s who of the field: Affirm’s Max Levchin, Twilio founder Jeff Lawson, and Piotr Dabkowski, the chief technology officer of voice-AI giant ElevenLabs.

Owning the model

Most voice AI tools wrap around someone else’s model. Bland does the opposite. The platform runs only on its own in-house voice models, and it will not let customers plug in OpenAI or Anthropic, even if they ask.

“We are one of one in that sense,” Granet told Fortune. The pitch to customers is blunt: here is what you are going to use, and we will own the result.

Dell Technologies Capital partner Elana Lian, who led the round, called voice “one of the hardest problems in AI” and pointed to that model ownership as the difference.

The 45-minute phone call

The idea was personal. Co-founder Sobhan Nejad’s aunt could not get through to her insurer by phone, and was denied access to treatment. The two engineers set out to build an agent that could stay on the line long enough to actually fix the problem.

That is the bet. Rivals mostly handle short, scripted calls: appointment reminders, password resets, routing. A typical Bland call runs 30 to 45 minutes.

In healthcare, the company says, that can mean walking an elderly patient through a blood-pressure reading and deciding in real time whether to escalate to emergency services.

The scale is real, at least by the company’s own numbers.

Bland says it now runs more than 3.5mn calls a week, processed over 175mn AI calls last year, and counts 250-plus enterprise customers, among them Samsara, Kin Insurance and CNO Financial Group. It is taking aim at the same enterprises that AI is already pulling out of the call centre.

A crowded, sceptical market

The competition is stiffening. PolyAI, a Cambridge spinout serving FedEx and Marriott, raised $86mn at a $750mn valuation in December. Replicant, Observe.ai, Retell AI and Cognigy are all chasing the same budgets, and most are already embedded in existing call-centre stacks.

The harder problem is resistance. Granet describes meetings with big call centres that had never looked at voice AI and were still running phone trees and legacy systems. Bland’s core verticals, healthcare and financial services, also come wrapped in strict rules on data, disclosure and HIPAA.

The company offers self-hosted deployment for sensitive customers, the kind of sovereignty pitch now common across enterprise voice AI.

Granet is candid about the gamble. The call-centre AI market is worth roughly $3bn today, by one estimate, and could reach $13.5bn by 2034. He thinks the prize is far larger. “There’s a chance that we’re wrong, and we die on that hill,” he said. “There’s also a chance that we’re right, and it turns out to be a $100 billion thesis.”
