@olly.rosewell: The one customer request that quietly kills solo founders: can you integrate with X Build it once and you maintain it forever, and when their system changes it's somehow your fault. I run every request through 3 tests first, and usually CSV import/export is all they actually needed. - 3 paying customers, unprompted - Would losing it lose the deal - Target system stable and documented - Offer CSV import and export - True integration: custom, paid upfront #saas #startup #software #entrepreneur #buildinpublic
