About Probo

GPAgent's own fund-neutral profile, written from public information. Updated Oct 5, 2026.

Summary

Probo handles end-to-end compliance for B2B software teams, replacing the need for a dedicated compliance hire. It collects requirements, manages documentation, risks, controls, and evidence, runs audits, and keeps everything current afterward. The work it replaces spans weeks of founder and engineering time spent on frameworks like SOC 2 and ISO 27001.

Business model

A managed compliance officer service plus a self-serve software portal, with an open-source self-hosted option available.

Go-to-market

Targets founders and small technical teams at B2B SaaS companies who need security certifications; customers can start through the self-serve portal or engage the expert-led compliance officer service directly.
