Proof Tech Stack

Legal tech marketplace connecting law firms with process servers nationwide

Legal Services Denver, Colorado 201–500 employees Founded 2017 Privately Held

Proof operates a two-sided marketplace for service of process, linking law firms with independent process servers across the US and internationally. The tech stack (Go, Ruby, Node.js, React, PostgreSQL, AWS/GCP/Azure) supports a modern web and mobile platform, but hiring reveals operational strain: legal and ops roles dominate (28 of 52 open positions), while engineering sits at 8, signaling scaling challenges in fulfillment and compliance rather than product velocity. Active projects around AI agents, supply acquisition, and lifecycle automation suggest Proof is automating its marketplace layers while contending with recruitment friction on the supply side.
