Brandon Foo spent four years building his first startup only to realize nobody needed it. The second time, he flipped the playbook - running SaaS product validation through 100+ customer interviews and charging $30 via Stripe before writing a single line of code.
Learn how Paragon used iterative SaaS product validation to pivot from a Firebase-like backend to an embedded integration platform, then scaled to millions in ARR with $16M in funding. Brandon shares the sell-before-you-build strategy, finding product-market fit through customer discovery, and why LinkedIn ads became his best B2B growth channel.
Paragon now serves 100+ customers with 90+ pre-built integrations, helping software companies connect with Salesforce, Slack, and HubSpot without building from scratch.
Key Lessons
🎯 Sell before you build for faster SaaS product validation: Brandon got customers to pay $30 via Stripe before writing code, proving demand without months of wasted development.
📉 A nice-to-have product kills growth even with great UX: Polymail had tens of thousands of users but was a $5-$10/month app with no urgent pain point.
🔄 SaaS product validation means finding what people don't want first: Paragon's initial idea was invalidated through customer discovery, but those same conversations surfaced the real opportunity.
💰 Raise prices iteratively to test willingness to pay: Starting at $30, then $50, then $100 measured how serious the pain point was at each level.
🚀 LinkedIn outperforms other paid channels for B2B acquisition: After iOS 14 killed Facebook/Instagram targeting, LinkedIn became Paragon's most consistent growth channel.
