Lex's founders reportedly pivoted to voice AI testing despite $5K in monthly recurring revenue

A founder says his team ran four ideas in parallel in summer 2024. One was Lex, which helped insurance lawyers find medical records and reached $5K in monthly recurring revenue, helping the team get into Y Combinator. He says they pivoted to voice AI testing halfway through the batch, leading to Cekura. His takeaway: revenue shows an idea is working, not that it's the best company for its founders to build.
