What we will never do

The last big "free" medical-records company paid for itself by selling physician attention to advertisers, selling prescriber data to pharma, and — eventually — taking money to put sponsored alerts inside the clinical decision. That company paid a $145 million settlement. We built Sigmund so that business model is impossible here.

• No ads. No pharma banner, no sponsored anything, ever.
• We do not sell your data. Not identified, not de-identified, not "aggregated." Your patients' information is not our product.
• Your data never leaves for a third-party AI. Sigmund's intelligence runs entirely on our own infrastructure. No OpenAI, no outside model ever sees your patients' information.
• No paid clinical alerts. Nobody can buy their way into what Sigmund recommends. The decision-support layer answers to the evidence, not to a sponsor.
• Your notes are yours. Export them and leave any time. No data-export gate.

So how is it free?

Two ways, both honest. The everyday tools run on grant-funded research infrastructure at the Sultan Lab — work that's already paying for the engine. And when the full decision-support layer launches, practices that want it will pay for that. The free tier isn't a loss leader hiding a catch; it's the mission, funded by the part of the business that earns its keep.

How to get access

Sigmund is onboarded by hand, one clinician at a time, so we can sign a BAA and set you up properly. If you run an outpatient practice or you're a trainee who wants in, request access through the waitlist and tell us about your setting. The founder reads every message.

Sigmund is investigational and intended to assist — not replace — clinical judgment. It does not prescribe or bill.
