Founders burn years in the wrong room.
Lattice built goal-setting software for 10 months. It went nowhere. Their co-founder Jack Altman said:
"We didn't think of it as HR software. We didn't know anything about HR software."
The market they needed — performance management — had Gallup publishing $2.4M–$35M per 10,000 employees in annual review costs. Deloitte had internally measured 1.8 million wasted hours and published the findings. The pain was quantified, public, and screaming. Lattice only found it because they happened to be adjacent to HR teams. After pivoting, they made 2x more revenue in month one than the entire previous year.
Spyne built AI photography for five industries at once — food, fashion, real estate, ecommerce, automotive. They couldn't tell which one needed them most. Their co-founder said:
"We realized we couldn't solve every problem deeply at our stage."
They abandoned 80% of their revenue to focus on automotive. It worked — $25K to $250K MRR in 12 months. But NADA, CDK Global, and Cox Automotive had been publishing per-vehicle carrying costs for years. The signal was there. Nobody pointed them to it.
Viblio built video AI that worked perfectly for sports footage categorization. A real market with real willingness to pay. But the founder shut down because:
"Neither were markets that I knew enough about, or was passionate enough about."
The technology worked. The market existed. The demand was real. But the founder couldn't reach it because nothing in her world surfaced it.
Product-market fit isn't always "study one market harder." Sometimes you just need someone to tell you that the people next door have the problem you solve, they've already measured it, and they're waiting.
