Meet the Team

Co-Founder & CEO

Tavio leads Staxyz’s product and design, drawing on his experience testing drugs and peptides for compounding pharmacies. As a biohacker, he is building the health record he wants for understanding what he takes and what changes.

Co-Founder & CTO

Ashley leads Staxyz’s engineering, applying a decade of statistical analysis and scientific software experience at CERN and Fermilab to personal health data. She built the account record store, sync engine and web app that turn scattered logs into a coherent health record.

Scientific Advisor & Investor

Cam is the lead scientist at a pharmaceutical release-testing startup, with experience in testing, data analysis and scientific instrumentation. He earned his PhD in physics at UCLA, conducted research at CERN and served as a project scientist at SLAC and Stanford.

Frequently Asked Questions

Staxyz is an iPhone app for people tracking peptides, GLP-1s and supplements. Log your doses and protocols, keep track of your supply and vials, and follow your symptoms, weight and lab results over time. Natt, the in-app assistant, answers questions about your own log, and Staxyz+ lets you ask more. Turn on Health sync and Staxyz also saves daily summaries from Apple Health. At launch, Staxyz is on iPhone only.

We're opening Staxyz in phases, so we can improve it with the people using it before we bring in more members. Phase 1 requests close December 31, 2026, at 11:59 PM PT. We review every request by hand, and if you're invited, your invite arrives by email.

Connect Staxyz to my AI links the AI assistant you already use to your Staxyz record, so you don't have to switch assistants. Every kind of data starts switched off, and you turn on only what you want to share. Your AI can add entries only if you allow it, and you can disconnect it any time in the app. It's part of Staxyz+.

Staxyz has a Free plan, and Staxyz+ is $5 a month or $36 a year at the early-member price. The yearly plan includes one free month; cancel at least 24 hours before your free month ends and you won't be charged. Your price is locked while you stay subscribed, including if you switch between monthly and yearly without a break. If you cancel and subscribe again later, you'll pay the price offered at that time. Staxyz+ renews automatically until you cancel, and you can cancel any time in your Apple account settings.

You can keep your doses and routines, your supply, your symptoms, your weight and your lab results in Staxyz, and see them together over time. With Staxyz+, you can also bring in lab results, weight and body composition from a file, such as a lab report PDF. Turn on Health sync and Staxyz also saves daily summaries from Apple Health.

Building useful health tools takes careful measurement and clear thinking about data. Tavio brings chemistry and pharmaceutical testing experience, Ashley brings physics and large-scale data analysis, and Cam brings physics research and pharmaceutical release-testing experience. Those backgrounds shape how we approach measurements, context, and evidence. They don't make us clinicians, and Staxyz isn't a replacement for medical care.
