100 Interviews Before Code: Finding SaaS Product-Market Fit
Brandon Foo is a second-time founder who learned the hard way that building a great product means nothing if nobody needs it badly enough to pay. His first startup, Polymail, was an email productivity app that attracted tens of thousands of users but never found a large enough market to sustain growth. That experience taught Brandon a critical lesson about finding product-market fit: stop building and start selling. When Brandon and his co-founder Ishmael started Paragon, they flipped the playbook. Instead of spending months writing code, they ran over 100 customer interviews, showed mockups and prototypes, and asked prospects to enter their credit cards on a Stripe form for a product that barely existed. They started at $30 per month and gradually raised prices to test the ceiling of customer willingness to pay. That iterative approach to finding product-market fit led them through several pivots. Paragon started as a backend-as-a-service (similar to Firebase), but customer conversations kept pointing to one consistent pain point: building and maintaining SaaS integrations. Brandon and Ishmael followed the signal, refined the product, and eventually built an embedded integration platform that helps software companies connect with tools like Salesforce, Slack, and HubSpot. Today, Paragon serves over 100 customers, supports 90+ integrations out of the box, and has grown to several million dollars in ARR with a team of 30+. They raised $16 million in venture funding, including a $13 million Series A led by Inspired Capital. Brandon also shares how LinkedIn ads became Paragon's most successful growth channel, and the delegation challenges he faces scaling from a founder-led company to a team-driven organization.
