<p>I'm just asking if you've ever used one.<p>I don't want to assume, but if you've used one, you would understand the benefits are far greater than weight loss.</p>

<p>The truth is a lot less exciting. We got into YC and registered the company name that night, and the domain name was available. The Ro connection was pointed out later. If we are forced to rebrand, we will be more thoughtful.</p>

<p>This is a really beautiful site. Thank you for sharing it.<p>I think the only thing that separates us is that we manufacture the drugs and probably own more of the supply chain than they do. But they're doing a much better job on the front end.</p>

<p>You seem to know a lot about this, and I was nodding along with a lot of your points as I was reading.<p>I was Stripe's first customer in 2010, so we solved the credit card processing issue :) it turns out that being in YC is good for more than just money.<p>You are right about HIPAA, everyone thinks this is much harder than it actually is, but GCP, OpenAI, Linq, everyone has given us a BAA.<p>We're definitely not trying to go after the market of people that are comfortable buying from Chinese suppliers and risking their health. When I built my mask factory, our masks were absolutely more expensive than Chinese masks, but what people were buying was a guarantee that it would meet certain filtration requirements. Some people are willing to pay for safety, but it's not important to everyone.<p>The only thing I really disagree with with you on is that this isn't a YC-scale company.<p>We are growing 56% compounded week -over-week, and I have every expectation we'll do $10 million this year, $100 million next.<p>We are making something that people are already buying and getting it to them in a safer, more cost-effective way.</p>

<p>The dosing starts out surprisingly simple. The magic is in the feedback loop: asking the patient how they're feeling, if they're getting the effects they want, and then having their doctor review and approve a new dose.<p>Point taken that RUO people are just yoloing this, I was one of them. Now, I can tell you that having a doctor in the loop with my health is very helpful.</p>

<p>We are co-manufacturing the API, and then we are bringing it in-house in the next 9 months.<p>The legal cutout that we have is on the personalization front, which is very well protected. The trick is that most compounders are not actually personalizing, and we are. Our feedback loop allows us to do real personalization on a week-by-week basis.</p>

<p>Fair criticism. It is AI slop all the way down. The only thing we focused on was the clinical aspects of the onboarding and the technical ability to be able to legally write a prescription and make and ship drugs, which was very complicated. We were able to accomplish this in less than 10 weeks. But I have not had time to go through all the marketing, and I apologize.</p>

<p>Hi HN,<p>I’m Lloyd, one of two founders of RonanRx (<a href="https://ronanrx.com/">https://ronanrx.com/</a>). We are building a vertically integrated pharmaceutical company with software for prescribing, telehealth, compounding, manufacturing, and delivery. We are starting with GLP-1s and peptides.<p>The path to RonanRx is fairly unconventional. During the pandemic, I built one of the largest mask manufacturing factories in the US. We could make a million masks in a day. We converted raw polypropylene pellets into finished pallets of masks.<p>I had a background in software from my YC W10 company, so we took a software approach to building our factory. We used machine learning and computer vision to optimize production. We also vertically integrated almost everything. It worked. We built an efficient manufacturing operation and grew the business to 50 million dollars in revenue. Then people actually stopped caring about masks. Fair enough.<p>Around the same time, I decided to try and lose the weight I had gained while building the factory. I ate nothing but chicken for six months. While this diet got some results, I plateaued. My doctor suggested tirzepatide, a GLP-1 medication.<p>For me, losing weight was only the beginning. "Food noise" was gone. I showed less interest in other compulsive behavior. I stopped scrolling Instagram and quit biting my nails. But that was just the beginning. I was born with a congenital heart defect called aortic stenosis. My whole life doctors told me I'd need open heart surgery in my 40s (I am 45 now). After just 18 months using tirzepatide, my cardiologist’s began to think (and still thinks) my surgery could be pushed back until I am 70 or 80.<p>This was all happening when I was deciding what to work on next. I wanted to keep working on manufacturing. I didn't want to build another product that could be replicated by a frontier model. Pharmaceutical manufacturing was the best combination of digital, physical, biological, and regulatory infrastructure I could find. The thing that bothered me was how disconnected all of the pieces were: telehealth, EHR, prescriptions, dispensing software, production, shipping. No one company has it all.<p>GLP-1s come in a handful of predefined doses, but patients obviously aren't standardized: they respond differently, lose weight at different rates, experience different side effects, and may need very different doses. Compounding pharmacies can fill customized prescriptions, but they are not built like software companies. Workflows are manual, fragmented, and disconnected from the patient’s data. It's our goal to connect those pieces with RonanRx.<p>Patients either come to us directly or are referred by a physician. Once a patient is in our system, we collect medical records, current meds, labs, and data from wearables. Our software follows the prescription through drug formulation, compounding, quality testing, and drug dispensing and distribution.<p>The most interesting feature is the feedback loop. As the patient is undergoing treatment, their response becomes data that can be used by their doctor to modify the treatment. We keep the doctor in the feedback loop.<p>We make money by selling drugs we manufacture. Because people can buy directly from us, their price is usually 3x-10x more affordable. We can do this because we start at the molecule and own the entire stack from manufacturing through prescribing, dispensing, and delivery, instead of paying a chain of middlemen at every step.<p>We are beginning with GLP-1s and peptides since this was where I personally experienced the issue; however, we are more interested in the potential of patient-specific pharmaceutical manufacturing.<p>We would love your feedback, especially if you have built pharmacy, manufacturing, clinical infrastructure, EHRs, or any other regulated software. There are a lot of assumptions in this model that should be tested.</p>
