    Floe: Spend Controls for Voice AI

    Floe is a spend control and governance platform designed for voice AI agents. It consolidates billing across multiple vendors into a single ledger, allowing teams to track the true cost and margin per call, customer, campaign, or agent in real time. The platform integrates directly with existing voice stacks like Vapi, Retell, Bland, LiveKit, and Pipecat without requiring migration.

    Key Features

    • Unified Ledger: Joins usage data across 7 to 20 vendors in real time to calculate the true per-call cost, including telephony, speech-to-text, models, and text-to-speech.

    • Pre-Call Gating: Enforces budgets and hard-stops runaway agents before upstream spend occurs, returning a 402 error when caps are hit.

    • BYOK or Keyless Routing: Users can bring their own provider keys (BYOK) or use a single Floe key to access a marketplace of 36+ services and 2,000+ payable APIs.

    • Low Latency: Operates with a median overhead of 38ms (p50) and a tail latency of approximately 180ms (p99) measured on live production traffic.

    • Open Source Guardrail: Offers floe-guard, a local, framework-agnostic, MIT-licensed tool to stop runaway agents without requiring an account.

    • Vendor Marketplace: Supports major models and services including OpenAI, Anthropic, Deepgram, ElevenLabs, Twilio, and Sarvam AI for 22+ Indian languages.

    Use Cases

    • Production Voice Agents: Managing multi-vendor billing and secure spending governance for live traffic on platforms like Vapi, Retell, and Bland.

    • Prototyping: Using the keyless fast lane to quickly build and test net-new agents without setting up multiple per-provider accounts.
