Is Retell AI profitable in 2026?

Retell AI reports reaching roughly 45 to 60 million dollars in annualized revenue by early to mid 2026, up about 650 percent year over year, on only 5.1 million dollars raised total, which the company and Sacra cite as evidence of profitability without further venture funding as of June 2026.

Retell AI is privately held and VC-backed, with no acquisition or parent company identified. It was co-founded in 2023 by CEO Bing Wu, along with Evie and Weijia, went through Y Combinator's Winter 2024 batch, and raised a 4.6 million dollar seed round in August 2024 led by Alt Capital.

Could AI replace Retell AI?

Retell AI's own middleware layer is exposed: OpenAI's Realtime API reached general availability in 2025 letting developers build voice agents directly, and Twilio natively integrated it for its 300,000 plus customers by August 2025, both bypassing platforms like Retell for core latency and turn-taking functions.

Who is Retell AI's biggest competitor?

ElevenLabs is Retell AI's most aggressive rival, having raised 500 million dollars at an 11 billion dollar valuation in February 2026 and shipped Conversational AI 2.0 with HIPAA compliance while cutting per-minute pricing roughly in half, directly pressuring Retell's pricing and differentiation.

How has Retell AI's revenue grown since its seed round?

Retell AI reported over 3 million dollars in annualized revenue at its August 2024 seed announcement. By April 2026, Sacra estimated annualized revenue near 60 million dollars, up from about 45 million at end of 2025, a roughly 650 percent year over year increase.

Has Retell AI raised a Series A?

As of June 27, 2026, Retell AI had not raised a Series A. Its last funding was a 4.6 million dollar seed round in August 2024 led by Alt Capital, roughly 22 months prior, despite reported ARR growth into the tens of millions.

The call

Retell runs a profitable middleware business squeezed between a cash-rich AI-native rival cutting prices and a distribution giant folding the same technology into its own platform for free.

Retell AI builds software that turns phone calls into AI conversations, charging companies per minute. It is being squeezed from two directions: Twilio (a much larger company) added the same AI capability directly into its product for 300,000+ existing customers, and ElevenLabs (a well-funded startup) launched a competing system and cut prices in half. The company's real protection is not the AI itself (which anyone can copy) but whether customers get locked in through workflow tools and integrations launched only recently; if price wars continue and those tools do not stick, Retell's current profits could evaporate against much better-funded competitors willing to lose money to win market share.

Why

AI pressure: ElevenLabs (Conversational AI 2.0). ElevenLabs, backed by $500M, cut per-minute pricing in half and added HIPAA, squeezing Retell's margin on the same intelligence layer it rents. Could AI do the core job? Yes, likely.

Bigger players: Twilio. Twilio built OpenAI Realtime directly into its platform for 300K+ existing customers, letting them skip Retell entirely. Could a giant copy it? Yes, easily.

What protects it. Conductor, Assure, and CRM workflow lock-in aim to keep enterprise ops tied to Retell even if the underlying model changes.

What would change this call

Retell announces or fails to announce a Series A within 12 months. Shows whether investors see workflow lock-in as durable against ElevenLabs and Twilio.
Retell's per-minute platform fee drops from current ~$0.07-0.08/min. Would indicate margin compression from ElevenLabs' price cuts is forcing a response.
Named Retell customers (Motorola, Lenovo, Anker, Spurs) publicly switch to Twilio AI Assistants or ElevenLabs. Would confirm workflow lock-in (Conductor, Assure) is not holding against rivals.

Key numbers

$45-60M ARR, up 650% YoY (2026-04)
55M+ AI calls/month, 30 calls/sec (2026-06-29)
$5.1M raised vs ElevenLabs' $500M round (2026-02)

Named risks

Middleware margin compression as ElevenLabs and OpenAI ship cheaper, more complete voice AI directly to developers. Severity: high
No Series A raised as of June 2026, 22 months after seed, despite rapid ARR growth, leaving capital cushion thin against well-funded rivals. Severity: medium
TCPA litigation surge (2,788 cases in 2024, up 67% YoY) creates vendor-chain liability exposure for AI voice call platforms. Severity: medium
EU AI Act high-risk obligations and Article 50 disclosure requirements take effect August 2, 2026, requiring product changes for EU deployments. Severity: medium
Conflicting public data on headcount and HQ location suggests an unstable public profile that could undermine enterprise trust. Severity: low
