OneTwenty Announces Closed Beta Launch
OneTwenty opens its closed beta to a first cohort of 25 founding members, chosen from more than 250 applicants, to test the wearable-to-labs model behind the platform.
Brooklyn, NY
OneTwenty has officially opened its closed beta, granting early access to a select group of 25 founding members from a pool of more than 250 applicants. This marks a key step in validating the platform’s biometric-driven longevity model, which integrates wearable data, lab work and targeted interventions for sleep, hormones, metabolism and energy.
Over the past few weeks the team completed roughly 50 one-on-one interviews and hand-selected testers who already track their health with devices like Apple Watch, Oura, smart scales and blood pressure monitors. This first cohort will help stress-test the onboarding flow, dashboard, data syncing, lab ordering and treatment loops.
Focus of the closed beta
This phase is centered on real-world reliability and refining the full care experience inside the platform. Testers will help evaluate:
- Core stability. Ensuring devices, labs and dashboards sync smoothly.
- User experience. Validating the clarity and ease of the onboarding steps.
- Clinical accuracy. Confirming that labs, questionnaires and biometric markers map cleanly to personalized protocols.
- Feedback loop. Capturing daily insights from testers so the team can ship rapid improvements and hotfixes.
“Closed beta is the bridge between building a system in theory and proving it works for real people day to day. We chose a small group intentionally so we can work closely with each member, gather precise data and tune the experience before we open the larger beta.”
Hayim Pinson, Founder of OneTwenty
Next steps and waitlist
The first wave of accounts will go live over several days. More invitations will open in January as OneTwenty onboards additional testers, including users already on HRT and those with advanced wearables.
