AI SaaS BYOK Key Management Platform

A backend service that handles multi-user API key management for SaaS apps using LLMs (bring-your-own-key or managed keys). Solves the infrastructure problem of securely issuing, rotating, and managing API keys at scale for AI-powered products.

The explosion of LLM-integrated SaaS products has created a genuine operational gap: most teams wire up API key handling themselves with ad-hoc solutions that break under multi-tenant load or fail basic security audits. No clear incumbent owns this specific slice — HashiCorp Vault handles secrets broadly but isn't purpose-built for BYOK/LLM key orchestration, and AWS Secrets Manager requires significant glue code. The $1k–$10k MRR band is realistic as a land-and-expand motion targeting early-stage SaaS builders who'll pay $50–200/month to avoid building this themselves, though the ceiling is low unless enterprise tiers with audit logging and SSO push ACV meaningfully higher. The biggest risk is that this is a thin wedge — once a handful of LLM middleware platforms (or OpenAI itself) bake key management natively into their offerings, the standalone case evaporates fast.
