01 / WHAT IT BUILT
What the company did
Opkit was a healthcare automation startup, founded in 2021 and part of Y Combinator's S21 batch. Its final product was a HIPAA-compliant generative AI call center for medical practices: the platform automated routine back-office phone calls - insurance verification, claims, prior authorizations, pharmacy prescription checks, and medical record collection - with a human-in-the-loop to handle edge cases. It had earlier built an insurance verification API for telehealth companies.

Events in the structured record
- Founded
Opkit was founded in 2021 as a healthcare automation company; it joined Y Combinator's Summer 2021 batch and raised a $1M seed round in March 2023.
- Acquired
Opkit pivoted to a generative-AI healthcare call center, launching the platform in August 2024. In late 2024 it was acqui-hired by 11x, the AI digital-worker startup: co-founders Sherwood Callaway and Justin Ko joined 11x to lead development of Alice 2.0, and the Opkit platform was wound down. The acquisition was announced alongside 11x's $50M Andreessen Horowitz-led Series B in November 2024.
