Execution Model: High-Agency Founding Teams

• Structure: We operate as a collective of in-house technical founders—not just specialized engineers. Initiatives are run by lean, autonomous squads built for velocity and maximum technical leverage. This model is centered around an Engineer DRI (Directly Responsible Individual) who maintains total ownership over the initiative's technical, product, and launch success, supported by fractional PM and Design resources.
• Cadence: We enforce rapid iteration and rapid market validation via 3-week sprints per initiative. This cadence forces fast deployment, immediate user feedback, and tight alignment with the internal betting table process, mirroring the intensity and speed of a lean startup.
