Spiral Scout

Spiral Scout builds AI agent systems and production workflow automation for companies that need more than a proof-of-concept. Founded in San Francisco in 2010, we are a team of 120+ engineers with 16 years of production engineering behind us. We specialize in AI implementation, Temporal-based workflow orchestration, CPQ rules engines, and legacy system modernization. We are a certified Temporal Solution Provider and the creators of Wippy.ai, an intelligent runtime built specifically for production-ready agent systems. 612+ projects shipped since 2010. We don't just consume open-source infrastructure. We build it. Our engineers created and maintain RoadRunner, a high-performance application server used by development teams worldwide, and are the authors and the official maintainers of one of Temporal's SDK. That depth of infrastructure experience is why we handle performance and reliability problems that generic agencies can't resolve. We work with two kinds of organizations. Established professional services firms in accounting, legal, consulting, and financial services, where manual workflows or aging systems are creating operational drag and institutional knowledge needs to be encoded into systems before it walks out the door. And founders building AI-native products in their former industries, who know the domain cold and need production-grade infrastructure that won't collapse when real users and real compliance requirements arrive. Every system we ship runs with real error handling, audit trails, observability, and the operational rigor production environments require. Our engineers embed into your workflow, act like owners, and hand off systems your internal team can run without us in the room. You own everything we build. Zero vendor lock-in. Results our clients have seen: manual work reduced by thousands of hours through intelligent agents, legacy systems modernized under tight funding deadlines, and platforms that held up through acquisitions, funding rounds, and full replatforms without breaking live operations. Named Clutch Global Winner for AI Agents (2025) and recognized as an AI agent expert by Clutch industry veterans (2026). If you need a partner that thinks in systems, moves fast without cutting corners, and builds AI that works in production rather than in demos, this is us.
