Simplex

What it does

Simplex is a managed service that handles provider enrollment for healthcare organizations. It takes over the entire process from CAQH setup to final payer determination. Simplex agents manage providers' CAQH profiles, submit applications to payers, chase follow-ups, fix corrections, and track every enrollment until the payer issues a decision. The service integrates with Airtable, spreadsheets, or internal systems to read pending enrollments and write status updates back. Each enrollment runs to final disposition with an evidence packet including step logs and video of exactly what was filed.

Who it is for

Simplex is built for healthcare organizations that need to enroll providers with multiple payers across multiple states. This includes medical groups, hospitals, and other provider organizations that manage credentialing and enrollment. The service is particularly relevant for organizations that have providers licensed in many states, as each provider-payer-state combination creates a separate enrollment record. The website mentions that a physician licensed in all 50 states can generate up to 250 enrollments, and therapists and dietitians can generate tens of enrollments at a time.

Why it matters

Provider enrollment is a complex, manual process that scales poorly. Every new provider multiplies across every state they are licensed in and every payer the organization is in network with. The website highlights that enrollment work grows multiplicatively while enrollment teams do not. Additionally, CAQH profiles must be re-attested every 120 days, and each of the 50+ payers has its own portal login, forms, rules, and follow-up methods. Simplex aims to solve this by taking over the operational work, allowing organizations to focus on their core business. The service is priced per finished enrollment, not per seat or per attempt, and includes corrections and follow-ups as part of the enrollment.

Launch signal

Simplex is part of Y Combinator's S24 batch, as indicated by the Hacker News launch post. The team includes alumni from MIT, Y Combinator, Waymo, and Tesla, as shown on the website. The service is SOC 2 Type II certified, HIPAA compliant, and offers a BAA before any data moves. It is US-based and onshore by design, with evidence for every action.

Brand and naming

The name "Simplex" suggests simplicity and straightforwardness, which aligns with the company's promise to make provider enrollment easy. The brand positions itself as a managed service rather than a software tool, emphasizing that it takes over the problem entirely. The tagline "Provider enrollment, run for you" reinforces this hands-off approach. The visual identity uses clean, professional design with a focus on payer logos to build trust.
