Forus

Today we’re introducing Forus and announcing $160M to build the foundation for modern medicine. Science should be the only limit to medicine. Today it isn’t. Drug discovery is moving faster, but the system that turns it into real-world treatment isn’t. forus.com/blog/forus-ann…

Patients with digestive diseases shouldn't face unnecessary delays getting the medications their physicians prescribe. We're partnering with @forus to help improve medication access. Learn more: ow.ly/Frec50ZnUWg

Thanks for having us @BainCapVC :P @forus <3

Forus is partnering with the @AmerGastroAssn to improve medication access for gastroenterology patients and ease the burden on GI providers and practices. Together with AGA, Forus is working to bring better infrastructure and visibility to the access challenges GI practices and patients face every day, connecting the dots between evidence-based clinical guidelines and everyday practice.

The payoff is that one gold standard now measures both directions, not just what a right answer looks like. ✏️ Full writeup by @IsabelChien_ here: build.forus.com/dev/blog/how-w…

But how do we measure whether it's right? A gold standard tells us when the judge approves correct answers. It can't tell us when it misses wrong ones, the more dangerous failure. We take correct answers and perturb them into plausible but wrong versions, then watch whether the judge notices. Critically, perturbed answers have to be wrong for this specific patient, not just “wrong-looking.” We feed the model the patient's diagnoses, medications, and therapy history to keep the fake answers grounded in the real chart.

Most evals can tell you when an LLM judge is right, but not when it's silently wrong. At Forus, our LLM judge reads prior authorization forms and decides whether a patient's medical record supports them. A missed error delays someone's medication. To catch those failures, we built a way to generate realistic wrong answers and test the judge against them. Here's how 🧵

We started @forus to build the foundation for modern medicine. Drug discovery is moving faster than ever, but the pipeline that turns it into societal impact hasn’t kept up. Science should be the only limit to medicine. Forus handles everything between a doctor’s decision and a patient starting treatment, and we’re already supporting thousands of physician practices and systems across the country. One of our specialist groups, Unio Health Partners in LA, shared their story:

Taking a sem off to work @forus (and eat my way around NYC) was one of the best decisions I’ve made to date

The average drug takes 10–15 years and $2.6B to reach patients — and even then, many who need it never receive it. A patient can have the right doctor, the right diagnosis, and the right medicine, and still not get treated. @forus is fixing that with an AI-powered network already used by thousands of practices.

I'm excited to publicly introduce Forus (formerly Tandem) and announce $160M to build the foundation for modern medicine. Drug discovery is moving faster than ever. The system that gets those breakthroughs to patients isn't even close to keeping up. We're building the AI-powered network that fixes that — connecting doctors, pharmacies, payers, and biopharma to bring new science to patients.

Congratulations to Sahir Jaggi and the entire @forus team on their $160M raise! We're excited to partner with them on this next chapter. Scientific progress in medicine is accelerating, but getting breakthroughs to patients remains slow and unreliable. Even after FDA approval, too many eligible patients never receive treatment, caught in a system that wasn't built for the complexity of modern medicine. Forus connects doctors, pharmacies, payers, and biopharma to bring new science to patients. Embedded into physician workflows, the platform automates all steps between a clinical decision and a patient starting treatment, including insurance authorization, financial assistance, and fulfillment routing. Sahir is building a team whose ambition matches the scale of the problem, and we're honored to be along for the ride.

Most drugs that make it through FDA approval still never reach the patients who need them. @forus (formerly Tandem) is fixing that by automating every step between a clinical decision and a patient starting treatment. 10x provider growth, 2 years running. Entirely word of mouth. Proud to back @sahirjaggi and the team as they raise $160M. forbes.com/sites/amyfeldm…

Nearly one third of Americans never fill the prescriptions that their doctors order. Sahir Jaggi thinks AI can help. Check out the full story to learn more: forbes.com/sites/amyfeldm…

There’s an opportunity to unlock an order of magnitude more medicine for society. We’re ~100 engineers and operators in New York, and we’re growing. We move fast and need to move faster.
