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. 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. 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, Bluevine and Parafin. Here's what makes us different from most venture-backed startups: we're profitable with strong unit economics, so we own our destiny. We're not forced to raise capital to survive; we'll raise strategically, on our terms, to accelerate the business when it makes sense. That changes how we work: - We make long-term decisions. We optimize for durable, long-term value, not short-term vanity metrics. - We run like a real business. We focus on what matters and have no patience for false busyness. - You share in what we build. Through profit sharing, when the company does well, you do well. We're looking for people who want to build deliberately, operate with discipline, and share in what we create. Kato is founded by a team with deep operating expertise in financial services and software engineering: - Pratik Risbud (CEO/Co-Founder): Former Investment Banker at Goldman Sachs and led Credit/Operations at Brex - David Zhu (CTO/Co-Founder): Former Software Engineer at Google and Engineering Manager at Brex Kato is backed by institutional capital from Pear VC and angel investors from top tech companies such as Brex, Bridge, and Square.

Every home buyer goes through the same three steps: searching for homes, touring them, and making an offer. Searching is still manual: buyers scroll listing portals for months, and agents hand-pick listings for each client. YUQI Homes AI changes that. Every buyer gets a personal AI home-finding agent, Grace, that recommends homes purely on fit. Every home gets a real video tour: an agent films one phone walkthrough, and YUQI turns it into a narrated, subtitled tour, usually within an hour. Every agent gets an AI assistant for clients, open houses and follow-ups. We're live on iOS and Android with 131 video listings across 17 California cities, 2,000+ video plays and 55 tour and contact requests, with zero paid marketing. YUQI was built by a licensed California broker who has closed $50M+ in sales and filmed video tours of nearly 1,000 homes. Now we're building the team. Why join - Real product, real users, and a founder who lives the problem every day. - Ground-floor ownership: early team members help shape the company. - A mission that matters: help every buyer find the right home, and let agents focus on showings and offers.
