Signifyd

Rajesh Ramanand serves as Co-Founder and CEO, while Mike Liberty acts as Co-Founder and Chief Risk Officer. The company's strategic direction has been overseen by the founding team since inception, with a leadership group that now includes a Chief AI Officer, Swami Vaithianathasamy, underscoring a focus on machine learning. The board includes investors from Premji Invest and Bain Capital Ventures, but operational control remains with the founding team.

Signifyd evaluates every transaction in real time against its Commerce Network and provides a ship-or-don't-ship recommendation. If the platform approves an order that later results in a chargeback due to fraud, Signifyd reimburses the merchant for the full amount — a 100% financial guarantee. This effectively transfers fraud liability from the retailer to Signifyd, making it an outcome-based underwriting model rather than a conventional software subscription.

Signifyd is an operating company, not an investment firm. It does not manage external capital or participate in fund structures on behalf of investors. The firm is backed by venture and growth equity from firms including Bain Capital Ventures, Menlo Ventures, Premji Invest, and American Express Ventures, who hold board stakes and provide strategic guidance to management.

Signifyd focuses on enterprise ecommerce retailers across verticals including consumer electronics, apparel, luxury goods, and mass merchandise. Named customers include Samsung, Lenovo, Walmart, Abercrombie & Fitch, and Lowe's. The platform is vertical-agnostic at the enterprise level, operating in over 100 countries to protect against both fraud and consumer abuse such as returns fraud and promo abuse.

Most fraud prevention providers supply risk scores that merchants interpret and act on themselves. Signifyd provides a guaranteed decision — approve or decline — and absorbs the financial consequence of that decision. This transforms the vendor's role from a passive risk-assessment tool to an active participant in conversion optimization, uniquely aligning its incentives with the merchant's top-line revenue growth.
