Chart

Chart discovered genuine demand through mortgage lenders' desperate search for faster income verification. Loan officers were spending hours manually requesting tax transcripts from the IRS, a process taking weeks. When Chart launched its API, lenders immediately began integrating it into their underwriting workflows without prompting—they weren't just expressing interest, they were actively building around the product. The early traction proved unmistakable: mortgage companies reduced verification time from 21 days to under 24 hours. This operational improvement drove rapid adoption across major lenders who saw direct revenue impact through faster loan closures. Chart measured genuine demand by tracking API call volume and integration depth rather than survey responses. Within months, the platform was processing thousands of verification requests weekly, with customers expanding usage across their entire loan pipelines. The behavioral signal was decisive—lenders weren't testing Chart; they were replacing their entire verification infrastructure with it, demonstrating that demand extended far beyond stated interest into fundamental business necessity.
