Problem

Building a production-grade voice agent requires stitching together speech-to-text, language models, text-to-speech, telephony, media transport, provider credentials, routing, monitoring, and fallback logic. That creates engineering overhead, fragmented provider bills, and difficult trade-offs among latency, accuracy, reliability, and cost. Speko’s central pain point is the “last mile” of voice AI infrastructure: choosing and maintaining the right provider pipeline for each language, intent, and workload rather than hand-building it.

The main use case is a developer or in-house voice team that wants to launch a phone, web, or API-based voice agent quickly without assembling and operating the stack themselves. Speko positions plain-English agent creation, browser testing, and phone deployment as a way to reduce setup time from a substantial integration project to minutes, while its benchmark-driven routing and bounded failover address production reliability and economics.

Product / Service

Speko is a managed, OpenRouter-style gateway for voice AI. One API and account connect teams to speech-to-text, language models, text-to-speech, realtime speech-to-speech, telephony, and routing providers. The platform reports coverage of 56 providers and 157 models, publishes benchmark boards for accuracy, latency, cost, and other voice-agent metrics, and uses those measurements plus a customer’s policy to select a route and establish failover order.

The delivery model is usage-based infrastructure with a self-serve platform and browser-based live testing, followed by deployment to a phone number, web widget, or API. Public Speko materials show a free starting allowance or credit and per-minute pricing, but they are not fully consistent: the homepage advertises $0.12 per minute, while comparison and pricing materials also reference $0.09 per connected minute or infrastructure usage. The benefit is a single managed integration and invoice instead of separate provider setup, hosting, routing, and monitoring work, while retaining provider choice and configuration control.

Market

Speko competes in developer tools and conversational voice-AI infrastructure, specifically the gateway, orchestration, and managed voice-agent platform layer rather than as a single speech or language-model vendor. Its closest publicly identified comparison is Pipecat, an open-source framework that teams assemble and self-host; Speko also names Vapi, Retell AI, and Bland AI as voice-AI alternatives. The underlying provider ecosystem includes vendors such as OpenAI, Anthropic, Google, ElevenLabs, Deepgram, Cartesia, AssemblyAI, and others, which Speko aggregates and routes across.

The company is very early-stage: Y Combinator lists Speko as an active Summer 2026 company founded in 2026 with a four-person team, and Speko identifies itself as YC-backed. The evidence shows product breadth, public benchmarks, a live platform, and free-credit or preview access, but no disclosed revenue, customer count, usage, or deployment metrics. It is therefore best characterized as an early commercial launch with traction not yet publicly quantified, rather than definitively labeling it pre-revenue.
