Ryan Grissinger
Co‑founder & Director of Product (Former CTO)
Executive product leader who speaks customer and code. I turn messy problems into systems that scale.
I blend executive strategy with hands‑on depth. I sit with customers and teams, map the real workflows, then architect simple systems that ship. My edge is pairing discovery with delivery so outcomes land fast without trading off quality or security.
Selected outcomes
- Scaled a national dealer platform from zero to 300+ dealers with clear domain models and measurable KPIs.
- Enabled eight straight years of growth by delivering systems that supported marketing, sales, operations, and accounting at scale.
- Built lead attribution and routing tying national campaigns to dealer performance with UTM tracking, geo logic, round‑robin rules, and program preferences.
- Raised delivery quality by institutionalizing product discovery, secure architecture, and sustainable engineering practices.
People × Systems
I run crisp discovery: stakeholder interviews, ride‑alongs, and quick prototypes. I translate the findings into decisions, data models, and a shipping cadence. This keeps cost, quality, and speed in balance.
Core competencies
- Product strategy and roadmapping
- Discovery interviewing and decision quality
- AI‑ and data‑informed operations
- Scalable architecture and security
- Cross‑functional leadership and facilitation
- Agile and lean execution
- Business process design
Signature problems I love
- Turning ambiguous opportunities into a clear, testable roadmap
- Aligning HubSpot, web, and back‑office data for revenue attribution
- Designing platforms for franchised or dealer networks
- Operationalizing AI where it measurably saves time or money
