Mortgage-AI Startup Valon Raises $150M Series D at $2.3B to Scale ValonOS Agents With Ribbit and a16z

Valon, which builds AI servicing software for the US mortgage industry, closed a $150M Series D led by new investor Ribbit Capital alongside existing backer a16z at a $2.3B valuation, roughly double its last mark. CEO Andrew Wang said ValonOS agents — which answer homeowner emails, allocate payments and run escrow analyses — now sit under contract on one in six US mortgages and generated $200M+ in contracted ARR within six months of opening the platform to industry partners.
