We Raised a $1.25M Seed to Continue Building the Open Source, Verifiable AI Router

TrustedRouter announced a $1.25 million seed round from investors including Sam Lessin, Bill Tai, Linda Avey, George Xing, and several technical and venture backers to expand its open-source AI routing platform. Publicly in beta since May, the company says it has grown through word of mouth, surpassed one billion tokens processed in a day, and attracted customers in privacy-sensitive fields such as legal, finance, and healthcare. Its service provides an OpenAI-compatible API for routing requests among more than 600 models and 81 providers, aiming to reduce costs, improve uptime, and allow users to select privacy requirements and geographic or confidential-computing constraints. TrustedRouter argues that end-to-end encryption, open-source code, remote attestation, and limited retention of billing metadata help customers verify that prompts and model outputs are not stored or used to create synthetic training data. The platform also offers automatic model selection, backup routing across providers with equivalent privacy settings, and multi-cloud infrastructure across AWS, Azure, and Google Cloud. It charges a 5.5% markup on provider token costs, while allowing customers to bring their own provider keys, and was initially built largely by its founder using AI development tools.
