Arkose Labs, which is developing a service that detects and mitigates online fraud, raises $22M Series B led by Microsoft's venture fund M12

Context & Ripple Effects
M12 keeps returning to the fraud-and-cybercrime detection category: the fund previously led HYAS's $6.2M Series A, which targets cybercriminal identification, and co-led NsKnox's $15M Series A in real-time payment fraud detection. Arkose Labs' $22M Series B extends that pattern into consumer-facing online fraud mitigation.
The raise also slots Arkose into a crowded but well-funded field — Bleckwen emerged from stealth with a $10M Series A for bank-focused AI fraud detection months earlier, and phishing specialist Ironscales raised a $15M Series B — setting up the follow-on $70M Series C led by SoftBank Vision Fund 2 that came just over a year later.
First-order effects
- Arkose Labs gets the capital to scale its fraud detection and mitigation service at a moment when every rival in the segment — Bleckwen, NsKnox, Ironscales — is also freshly funded and racing to sign customers.
Second-order effects
- Microsoft's M12 now holds positions across multiple fraud and cybercrime detection vendors (HYAS, NsKnox, Arkose Labs), giving it portfolio-wide visibility into where enterprise security budgets are flowing and potential bundling leverage through its cloud relationships.
Third-order effects
- If corporate venture arms keep anchoring rounds in this category, fraud detection consolidates around platform-aligned vendors rather than independents — with cloud giants effectively underwriting the security stack their own customers will buy from.
The trend: Corporate venture capital from cloud platforms is becoming the default financing layer for fraud and cybercrime detection startups, shaping which vendors reach scale.
