Company overview

Lenders spend over $24B every year hiring agents to perform manual, repetitive servicing work. Existing AI solutions try to automate this, but they treat regulatory guardrails as an afterthought - meaning they can’t guarantee compliance and can’t be trusted with critical servicing workflows.

Kato takes a different approach.

Regulations aren’t an afterthought – they’re the foundation. We start with a regulatory rules system and layer an AI decision engine on top of it. With this architecture, we’re building an AI-powered servicing platform that automates critical workflows across every channel with full compliance and best-in-class recoveries. Human teams are then free to focus only on the judgment-driven work that truly needs them.

We are starting today with a compliance first Voice AI agent that handles outbound and inbound loan servicing calls, and are already in production with major names in the fintech lending space like Bilt Rewards https://biltrewards.com/ and Parafin https://www.parafin.com/.

Kato is founded by a team with deep operating expertise in financial services and software engineering:

• Pratik Risbud https://www.linkedin.com/in/pratikrisbud/ (CEO/Co-Founder): Former Investment Banker at Goldman Sachs and led Credit/Operations at Brex
• David Zhu https://www.linkedin.com/in/david-y-zhu/ (CTO/Co-Founder): Former Software Engineer at Google and Engineering Manager at Brex
