Speko
It monetizes a managed routing layer that bundles many voice models' STT/LLM/TTS behind one API, charging per minute or a 5% markup on provider rates.
Speko is a Y Combinator-backed voice AI routing platform offering a hosted Router (router.speko.dev) and an open customer-side Gateway. The Router unifies STT, LLM and TTS behind typed-contract APIs, auto-selecting routes by latency, quality, cost or a balanced objective, or pinning a provider/model. Pricing is $0.09 per minute all-in on Speko infrastructure, or a 5% markup on the provider's published rate, with $10 signup credit. The site also publishes cross-language benchmarks across 17 languages, showing no single model wins everywhere.
Revenue and pricing
Revenue range： Not publicly disclosed. Monetization： Usage-based.
Paid trigger： No free tier; $10 signup credit is granted, after which usage is billed at $0.09/minute or provider rate plus 5%.
Market analysis
Routing driven by measured benchmark data showing model strengths per language, plus two distinct product boundaries: a hosted Router and an open Gateway that supports BYOK credential custody.
The voice AI infrastructure space is crowded with Vapi, Retell AI and Bland AI already established, and upstream model vendors may offer unified interfaces directly.
Acquisition and operations
Primary channel： Developer Ecosystem.
Wins search and AI retrieval through comparison pages (Speko vs Bland AI, vs Retell AI, vs Vapi), alternatives pages (Vapi Alternatives), topic pages on voice agent platforms and latency measurement, plus llms.txt and machine-readable catalogs.
Visit site -> Get API key -> sign up with $10 credit -> pay $0.09/minute or provider rate plus 5% after credit runs out -> move to Enterprise contract at scale.
Reusable and non-reusable parts
Copy： Abstract multiple vendors' comparable capabilities into one unified API with smart routing, build selection authority through public benchmark data, and lower integration friction with open-source client SDKs and MCP integrations.
Do not copy blindly： Hard to replicate: Y Combinator backing, the accumulated cross-language benchmark dataset across 17 languages, and the engineering investment of maintaining both a hosted Router and an open-source Gateway as separate product boundaries.
