  • Ritivel
    Ritivel
    Y Combinator LogoW2026
    Active • 3 employees • San Francisco, CA, USA
    Ritivel is an AI-native workspace for regulatory and medical writing teams at life sciences companies. Our AI agents draft CTDs, CSRs, INDs, and BLAs in minutes instead of weeks, helping drugs reach patients faster. Every month a drug is delayed from reaching the market costs pharma companies ~$45M in lost revenue and more importantly, delays treatment for thousands of patients who need it. Yet regulatory teams are stuck in a painful, months-long process: synthesizing thousands of pages of clinical data, hunting through SharePoint folders for the right documents, chasing colleagues for missing inputs, and manually drafting submissions. Ritivel deploys AI agents that transform how regulatory teams work. Our agents generate comprehensive first drafts directly in Microsoft Word, following FDA formatting requirements and pulling from your existing clinical data and prior submissions. Every data point includes citations linked back to the original source, so reviewers can verify with one click. Connected to SharePoint and Veeva, our agents automatically source the right documents. Integrated with Outlook, they handle reminder emails and follow-ups automatically. We're engineers who previously built AI copilots at Microsoft Research. After 50+ conversations with pharma professionals, we discovered the critical bottleneck in regulatory submissions and built Ritivel to solve it.

  • Cardamon
    Cardamon
    Y Combinator LogoW2025
    Active • 2 employees • London
    Cardamon is an AI powered platform that ingests relevant regulation, understands what applies to each regulated financial firm, and gets compliance officers from regulation, to obligations, to product requirements in minutes - not weeks. Financial firms face a host of complex regulations that make it incredibly painful to launch and maintain products in a compliant way. As a Product team at Revolut, we felt this pain deeply ourselves - we had products ready to launch but stuck in compliance limbo, often for weeks. Turns out, getting compliant took as long as building the product itself. Frustrated, we dug in and were shocked by how manual and inefficient the processes were. That’s when it clicked: there’s a huge opportunity to automate the boring stuff (and solve our own problem!). Compliance teams win because they ditch the tedious tasks. Product teams win because they ship faster. Everyone’s happy.

    With Kyber, companies operating in regulated industries can quickly draft, review, and send complex regulatory notices.

Kyber not only saves these teams time, but significantly improves consistency, compliance, and personalization.
