• Funding and valuation: Blacksmith raised $45 million in Series B funding led by Peak XV Partners, valuing the company at $550 million, up from a $60 million valuation in its Series A less than a year ago.
  • Customer growth: The company now serves over 5,000 customers, including Mercury, Supabase, Clerk, Ashby, and Expensify, up from more than 700 customers less than a year ago.
  • Revenue: Blacksmith reached a $10 million annualized revenue run rate with just 10 employees and has since grown revenue to tens of millions of dollars, though CEO Aditya Jayaprakash declined to provide a specific updated ARR figure.
  • Caveat: These revenue and customer numbers are self-reported by the CEO and not independently verified, which is typical for a startup announcement.
