Adentris (Y Combinator) builds AI-powered revenue integrity and compliance software for behavioral health and substance use disorder providers. We're now building the services side of the business: a technology-enabled RCM services operation, from a blank page. We're hiring the founder-like leader to build it. This is a hands-on, entrepreneurial role reporting to the Chief Product Officer. You'll define how Adentris delivers RCM services, translate deep billing expertise into product specifications and automation requirements, deliver for the first customers yourself, then hire the team behind you, and work with the founders on acquisitions in the SUD billing services market. You should know what separates an exceptional BH/SUD billing organization from an average one. Your job is to build that judgment into a scalable operation and into software. The founders You'd be working directly with all three founders. Dmitry Karpov (CEO) is a second-time YC founder with a track record in B2B enterprise products and go-to-market; he leads executive sales, and you'll be in those rooms with him. Sergey Yudovskiy (CPO), your direct manager, is also a second-time YC founder: he previously ran ElectroNeek (YC W20) as CEO, scaling it to ~$5M ARR across 30+ countries, and comes from a family of physicians, which is why revenue lost to documentation errors is personal, not abstract. Alex Odin (CTO) is a third-time founder who led AI at ManyChat ($140M+ ARR); he owns the multi-agent architecture your automation specs will be built on. Your first 90 days

• First 30 days: get inside our live BH/SUD customer engagements. Map their revenue cycle end to end, take ownership of service delivery for at least one account, and stand up the baseline metrics dashboard: clean-claim rate, denial rate, days in A/R.
• By day 60: your first process maps and automation specifications are in engineering's hands, and the service delivery model (SOPs, quality controls, staffing plan) exists on paper because you wrote it.
• By day 90: you've onboarded a customer on the delivery model you designed, joined executive-level sales conversations as the subject-matter expert, and built the first version of our framework for evaluating billing-company acquisition targets.
