Simbie AI

Vivek Olumbe and Natalia Khosla MD looked at healthcare and saw something that's been broken for decades—patients falling through the cracks. Thirty percent of return visits never happen. Not because patients don't want care, but because the follow-up logistics are a nightmare and nobody's actually making sure they get to their next appointment. That costs doctors 10 percent of their revenue. Simbie AI just fixed it.

They're Y Combinator-backed and they've built clinically intelligent AI agents that live inside the EHR and proactively reach out to patients at the moments that matter most—right after a new diagnosis, a new prescription, or when diagnostic tests are ordered. These are the vulnerable touchpoints where patients get lost. Simbie's AI doesn't just send a reminder and call it a day. It answers patient messages via text and voice, it handles the back-and-forth, and it actually closes the loop. No more ghost appointments. No more revenue walking out the door because nobody followed up.

Natalia Khosla isn't some tech founder playing doctor—she's a physician who lived this problem firsthand. Combine that with Vivek Olumbe's previous launches experience and you've got a team that understands both the clinical reality and how to scale a product. They're based in New York and they're looking for healthcare systems and practices who are tired of leaving money on the table. Every missed follow-up is a missed opportunity—and Simbie AI just turned those missed opportunities into a revenue line item.
