Medbill AI is an assistant that saves consumers time and money on healthcare and medical bills.

Medical bills are a massive problem. They are confusing, over 40% contain errors, 17% of claims are denied by insurance, and often represent very large sums of money. As a result, 100 million Americans are saddled with medical debt, and medical bills cause nearly 70% of personal bankruptcies in the US.

Dealing with unexpectedly high medical bills is time-consuming, complex, and stressful. Stuck between their providers, payers, and bill collectors, consumers too frequently have to make numerous phone calls, wait on hold, and even send paper letters and faxes. Appealing insurance denials, resolving billing errors, negotiating bills, and filing out-of-network claims require expert knowledge that most consumers don't have.

Thanks to AI and new healthcare regulations around data access and price transparency, we can now automate this soul-crushing work and empower consumers to fight back against this broken system. Beyond medical bills, we help people through their entire healthcare journey as they switch health insurance or look for care that fits their budget.

If you're excited to work on this exciting problem, please get in touch! We're looking for talented founding engineers and designers to join us on this mission.
