Insurance startup Corgi has closed a second extension of its Series B round, raising its valuation to $4 billion. The company previously raised a $106 million B1 round in May at a $2.6 billion valuation, following a $160 million Series B at $1.3 billion in early May and a $108 million Series A in January at an undisclosed post‑money valuation estimated at $630 million. At its Series A launch seven months ago, Corgi reported an annualized revenue run rate of $40 million, a figure it expects to grow to $450 million by the end of the year. The startup uses artificial intelligence to generate instant quotes and accelerate claim payments, and offers liability, tech, employment, renters and auto insurance products. It operates Risk Retention Groups, which allow industry participants to self‑insure by pooling resources, but these groups are not backed by state guaranty funds and can be depleted by large claims. Corgi also provides data room software and runs two 24‑hour coffee shops in San Francisco and Atlanta, with plans to open five additional locations in New York and London. Founder and CEO Nico Laqua has said he expects employees to work seven days a week. The amount of money raised in the latest round has not been disclosed, and Corgi declined to comment. Corgi intends to open additional coffee shop locations and expand its insurance offerings, while the size of the latest investment remains undisclosed.
