Instnt

Instnt is an identity fraud loss insurance company for financial institutions, providing AI-powered underwriting that transfers identity fraud liability off a business's balance sheet onto S&P AA+-rated global insurers including Munich Re and Swiss Re. The company's platform operates as a drop-in agent — installed like an analytics tag on web and mobile onboarding flows — that observes identity, device, behavioral, and transaction signals across 1.25M+ data points to actuarially price the residual fraud-loss risk that existing detection stacks cannot eliminate. Each approved account is bound under an insurance policy at approval; when fraud slips through, covered losses are reimbursed within 30 days through Sedgwick as the third-party administrator, denial-free. Instnt is based in New York, founded in 2019 by Sunil Madhu, and serves financial services, e-commerce, cryptocurrency, gaming, government, and healthcare sectors. The company positions itself alongside — not in place of — existing KYC/KYB stacks such as Socure and Alloy, covering the residual loss that detection tools cannot prevent. U.S. institutions absorbed an estimated $23B in identity fraud losses in 2025, with over 80% of new-account fraud now synthetic.
