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

Proof operates a two-sided marketplace linking law firms to independent process servers across the US and internationally, with live tracking and notarized proof of service. The tech stack—Go, GraphQL, React, PostgreSQL, PostGIS—reflects a geolocation-heavy backend (PostGIS for mapping verification), while active adoption of AI integration and a product-heavy hiring mix (13 of 21 roles) signal a shift toward workflow automation and embedded intelligence rather than pure marketplace infrastructure.
