In this interview‑style workshop, host Angelina Yang talks with Sadaf Ayub, a fractional COO with a background at Google and Meta, about the hidden operational and financial decisions early‑stage founders must make. Ayub explains her “underwriting” framework: start by defining the founder’s long‑term vision, then work backwards to expose gaps in technology, product, team, financing, and legal structure. She stresses that founders often mistake narrative for reality, especially around co‑founder relationships, equity splits, and financing choices. Key take‑aways include: (1) co‑founders should be chosen from trusted networks, equity need not be 50/50, and early “prenup‑style” agreements are essential; (2) personal and business finances must never be commingled – use proper loan or SAFE documents and involve lawyers; (3) self‑funding is viable but requires disciplined budgeting (≈ $20‑30K for incorporation, legal, and fractional staff) and clear milestones to decide if external capital is needed; (4) different financing instruments (SAFE, convertible note, loan) have distinct tax and dilution implications, and valuation caps must be modeled against future conversion events; (5) AI can help model scenarios but does not replace legal counsel; (6) open‑source founders must assess licensing and enterprise‑readiness risks early; (7) founders should habitually view decisions through the lenses of investors, co‑founders, and customers to avoid emotional bias. The conversation ends with a concise piece of advice: regularly step outside your own perspective to identify and address gaps before they become fatal.
