Speko
Speko is a YC S26 startup building one API to route voice AI across speech and language providers.
Speko bets developers want to mix speech providers, while richer rivals and unified AI models both push toward picking just one.
Speko is a tool that lets businesses use voice AI from different companies at the same time, picking the best one for each call. Right now, bigger companies like Vapi and ElevenLabs are well-funded and already handle billions of calls, and they are building the same routing feature themselves. The real threat is that OpenAI and Google are making voice AI systems that work end-to-end on their own, meaning customers may not need to mix and match providers anymore. Speko would change the picture if it gets real customers and revenue before Vapi or ElevenLabs finish their own multi-provider tools in the next 6 to 12 months.
OpenAI or Google release a new unified speech-to-speech API update. Shows frontier labs collapsing the multi-provider fragmentation Speko's model routes around.
Speko discloses a named paying customer or seed funding at YC S26 Demo Day. Shows whether Speko has any real production traction beyond a pre-seed concept.
- Vapi processed 1B+ calls, $500M valuation
- ElevenLabs in talks at $22B valuation
- Speko claims 340ms median latency (vendor claim)
- No disclosed revenue, customers, or seed funding as of July 2026.
- Well-funded incumbents Vapi and ElevenLabs could ship native multi-provider routing within 6 to 12 months.
- Unified speech-to-speech models from OpenAI and Google erode the fragmentation Speko's routing premise depends on.
- EU AI Act synthetic-voice disclosure rule effective August 2, 2026 could impose compliance burden on routed TTS providers.
- Very small team with no open job postings signals limited execution capacity against well-capitalized rivals.
| Rival | Direction | Evidence |
|---|---|---|
| Vapi | losing to | Vapi at $500M valuation with 1B+ calls and Amazon Ring win over 40 rivals, May 2026, vs Speko's no disclosed traction |
| ElevenLabs | losing to | ElevenLabs at $11B to $22B valuation runs competing ElevenAgents platform, Feb to Jul 2026 |
| Deepgram | contesting | Deepgram, a $1.3B-valued STT provider, is one of the providers Speko benchmarks and routes to, Jan 2026 |
| OpenAI, Google (unified speech-to-speech APIs) | losing to | Native realtime speech APIs collapse multi-provider routing need Speko's benchmarks track as of Jul 2026 |
- Is Speko profitable or generating revenue in 2026?
- No revenue, customer count, or named-logo disclosures for Speko have been found as of July 2026. The company, a Y Combinator S26 member, publicizes technical benchmarks like ~340ms latency but has no public commercial traction metrics.
- Who is Speko's biggest competitor?
- Vapi is Speko's closest platform rival, having raised $50M at a ~$500M valuation in May 2026, processed over 1 billion calls, and won Amazon Ring's business over 40 other vendors. ElevenLabs, valued at $11B to $22B, also competes via its ElevenAgents platform.
- Could AI make Speko's voice-routing gateway unnecessary?
- Yes, this is a structural risk: frontier labs like OpenAI and Google are shipping unified speech-to-speech APIs (e.g., GPT-4o Transcribe) that collapse the STT/LLM/TTS fragmentation Speko's routing premise depends on, as reflected in Speko's own July 2026 benchmark comparisons.
- Who owns or funds Speko?
- Speko is privately held with Y Combinator listed as its investor of record via the Summer 2026 (S26) accelerator batch, per CB Insights as of July 2026. No seed, Series A, or valuation figures have been publicly disclosed for the company.
- What does Speko's product actually do?
- Speko is a voice-AI gateway, described as 'OpenRouter for voice AI,' that routes speech-to-text, LLM, and text-to-speech calls to the best provider per language, latency, and cost target with automatic failover, per its site as of July 2026.
- Can Speko survive against Vapi and ElevenLabs?
- It faces a narrowing window: Vapi ($500M valuation, 1B+ calls) and ElevenLabs ($11B to $22B valuation) could each ship native multi-provider routing as a feature within roughly 6 to 12 months of July 2026, per competitive analysis, eroding Speko's core differentiator before it scales.
