Oso Company Stability & Growth

Expansion & Growth Outlook

Funding and investor confidence: We've raised $26M in total funding, with our most recent Series A led by Sequoia. Our investor base includes Felicis, Harpoon Ventures, SV Angel, Company Ventures, and Highland Capital, plus notable entrepreneurs who are technical experts in building and scaling developer tools. This level of backing from sophisticated investors reflects strong confidence in our growth potential.

Market opportunity: We're addressing a universal problem that every software company faces. Authorization has existed as long as computers themselves, yet most developers still build it manually. Like Stripe did for payments and Twilio for messaging, we're creating the category-defining solution for authorization. The total addressable market is massive because every application needs authorization.

Customer adoption and use cases: Companies are moving away from hardcoded authorization and adopting Oso to manage complex access control, including RBAC, ReBAC, ABAC, and secure AI applications. Our customers report cutting implementation time by up to 4x and reducing the burden of maintaining authorization logic. We're seeing adoption across various company sizes and use cases, from startups to enterprises.

Product expansion: We've evolved from an open-source library to Oso Cloud, a fully managed authorization service. This progression shows product-market fit and our ability to scale our solution to meet enterprise requirements like fine-grained access controls, custom roles, and permissions-aware AI applications.

Team growth: We're actively making foundational hires across engineering, sales, and other functions. These are the team members who will scale their careers as we scale the company, indicating we're in a growth phase with expanding opportunities.

Industry recognition: We've been named a Highflier in cybersecurity by CB Insights alongside established players like SailPoint and Ory. We've received coverage in TechCrunch and recognition on Primary Venture Partners' Infrastructure Focal list for New York founders shaping the tech ecosystem.

Employee confidence: 95% of employees believe Oso has a positive business outlook, and 100% would recommend working here to a friend, based on Glassdoor reviews. This internal confidence reflects what team members see firsthand about our traction and trajectory.
