They were building a Segment competitor. It was working—customers were paying. But every sales call, prospects kept asking about the backend tech instead of the product. So they killed the roadmap and pivoted. It took them 18 months to hit $1M ARR. Then they started growing. And so far, they've raised $350M. Viraj walks through exactly how he validated the pivot, landed the first 10 customers, and why being outside Silicon Valley forced him to show more traction than everyone else.Why You Should ListenHow to know when your side feature is actually your real productThe exact question to ask prospects to validate willingness to payWhy getting to $1M ARR slowly can set you up to scale fasterHow to compete when you're not based in Silicon ValleyWhat talking to your first customer 4x a day for 2 months teaches youKeywordsstartup podcast, startup podcast for founders, open source startup, B2B SaaS growth, pivot strategy, developer tools startup, finding product market fit, early stage fundraising, design partners, commercial open source00:00:00 Intro00:01:46 Getting caught at the Coldplay concert00:14:29 Deciding to Pivot From a Working Product to Something New00:17:27 Building a Business Around Open Source Technology00:19:38 Selling Before You Build00:27:37 Talking to the First Customer Four Times a Day00:30:51 Landing the First Ten Customers00:35:10 Fundraising Without Silicon Valley Pedigree00:38:48 When He Knew He Had Product Market FitRetrySend me a message to let me know what you think!
