Builds personal AI agents for team coordination. Each user gets a dedicated assistant that collaborates with teammates' agents for scheduling, handoffs, questions, ticket updates, and thread responses across sales, engineering, and operations.
Personal AI agents that coordinate agent-to-agent. Handles scheduling, handoffs, ticket updates, thread responses. Integrating with email/calendar/CRM/document management. Works across sales, eng, and ops teams.
GitHub shows C++ language server and VSCode extension development. Deliberate stealth posture ahead of YC W26 Demo Day launch. Both founders also co-founded Traverse (YC W26), a data research lab for non-verifiable work focused on ambiguous, taste-dependent domains.
AI agents automate scheduling, document collection, and borrower follow-ups across the entire mortgage origination pipeline.
An AI assistant handles all the back-and-forth scheduling, document chasing, and status updates so loan officers can focus on closing deals instead of playing phone tag.
It's like giving every loan officer a hyper-organized executive assistant who never sleeps, never forgets a document, and somehow gets along with everyone else's assistant too.
Personal AI agents answer routine internal questions by querying teammates' agents, eliminating repetitive Slack messages and email threads.
Instead of pinging your coworker for the same status update for the fifth time, your AI agent just asks their AI agent and gets you the answer instantly.
It's like having a personal librarian who also happens to be best friends with every other librarian in the building—and they all gossip productively.
AI agents draft and send personalized borrower follow-ups in the loan officer's voice, keeping deals moving without manual effort.
Your AI writes follow-up emails to borrowers that sound exactly like you—except it never procrastinates and never forgets.
It's like cloning yourself—but only the version of you that's really good at writing emails and never gets distracted by lunch.
AI agents automatically collect, classify, and validate borrower documents to prepare complete underwriting packages with minimal human intervention.
The AI checks every document in a loan file before it goes to underwriting, catching missing pages and mismatched numbers so humans don't have to.
It's like having a perfectionist intern who reads every single page of every document, highlights every mismatch in red, and never once complains about it.
Lance Yan (ex-Kalshi, founded wat.ai at Waterloo) and Zachary Yu are also co-founders of Traverse (YC W26), a data research lab for frontier model training on non-verifiable work. Rare blend of production ML engineering and academic rigor. Both accepted into YC W26 with two companies simultaneously.
