Problem

Probo addresses the administrative and strategic burden of security and regulatory compliance for startups and small technology companies. Compliance work is often repetitive, fragmented, and disconnected from how a business actually operates: founders and engineers can lose weeks to checklists, document requests, evidence gathering, and audit preparation, while also paying for overlapping tools or services. The economic cost is both wasted internal capacity and slower revenue growth when a company cannot satisfy enterprise security requirements or demonstrate trust quickly.

The primary use case is helping a growing software company achieve SOC 2 or ISO 27001 readiness without building an in-house compliance function. Probo also supports GDPR, HIPAA, FERPA, and related frameworks, enabling companies to meet customer, procurement, and regulatory requirements while keeping their teams focused on product and sales.

Product / Service

Probo combines a managed compliance service with an open-source GRC platform. Its compliance officers review the customer’s environment, complete risk and vendor assessments, identify gaps, define an appropriately scoped program, and manage policies, controls, evidence, documentation, and auditor communications. Evidence collection, updates, approvals, and workflows are automated through the platform, while customers participate mainly in the decisions and calls that require their involvement.

After certification, Probo continues monitoring controls, refreshing evidence, maintaining assessments, and keeping the organization audit-ready. The underlying platform is self-hostable and MIT-licensed, with web, CLI, GraphQL, and MCP interfaces so engineering teams and AI agents can automate GRC work. A trust page, Slack workflows, and direct expert support extend the benefit beyond passing an audit to making compliance an ongoing sales and operating asset.

Market

Probo competes in B2B compliance automation, governance-risk-and-compliance software, and cybersecurity services, with a positioning aimed at fast-moving startups and engineering-led teams. Its clearest named competitor is Vanta, which Probo contrasts as a DIY automation tool against Probo’s more hands-on, full-service model; Drata is another adjacent platform in the broader compliance-automation category. Probo’s differentiation is the combination of open-source software, expert delivery, and an effort to avoid unnecessary frameworks or platform bloat.

The company was founded in 2024, joined Y Combinator’s Spring 2025 batch, and is listed as an active SaaS, B2B compliance and cybersecurity company. Its YC launch post reported that it had already worked with 39 companies over a two-month period to obtain SOC 2, HIPAA, or ISO 27001, while the public GitHub repository showed 1,239 stars and 182 forks at research time. The company website also presents customer testimonials and case studies involving organizations such as Ahrefs, Helix-DB, Blaxel, Vybe, and Sessionboard. No public revenue figure was identified, so the available evidence supports early commercial traction but does not establish revenue scale or justify labeling Probo pre-revenue.
