Lupin & Holmes was founded by Roni Carta and builds an upstream security platform called Depi that maps real attack paths to help enterprises spot attacks before they happen. The startup says it has several Fortune 500 clients, and names Ledger as one customer. Carta, 23, previously worked as a professional bug bounty hunter and a red team/security tester at ManoMano, earning nearly $800,000 in bounty rewards from companies including Google, Amazon and Netflix. The company has attracted sizable pre-seed capital, raising $5.9M in the recent round. Lupin & Holmes is hiring roughly 10 people and will deploy the funding toward research, product development and scaling the team. The company emphasizes its grounding in hacker culture as core to its approach.
