About AIOS
AIOS is building the world’s first full-stack AI doctor.
We’re at $450M ARR, growing from $7M/yr in April 2025. We’re faithfully serving >200k/mo patients via Bolt Pharmacy, our main UK brand. We’ve just launched Bolt Med, our international brand. We’re profitable.
Our strategy exists at the intersection of two strong theses:
- The AI doctor that wins will get to escape velocity using GLP-1s, the fastest growing consumer product in history.
- The $2T European healthcare market is overlooked by the most talented builders.
Our master plan:
- Step 0 → $100M/yr by end of 2025: We went from $10M to $100M in 6 months serving the UK GLP-1 market.
- Step 1 → $1B ARR by end of 2026: Since April 2025 we've grown from 3k to 200k UK active GLP-1 patients. We’ll continue this growth curve to hit $1B ARR.
- Step 2 → $10B ARR by end of 2028: Blitzscale Europe. We’ll be Europe’s largest GLP-1 provider.
- Step 3 → $100B/yr by end of 2030: Get regulatory approval across Europe for our Full Autonomous Prescribing (FAP) system. Win contracts at scale with European payers to mass replace human labor. We’ll be the dominant full-stack AI doctor in Europe.
- Step 4 → $1T/yr by end of 2035: With one line of code and zero human time, you can use AIOS to treat any patient globally with any medication.
In so doing, we’ll become the world’s first trillion-dollar healthcare company.
We’re a young, founder-led company. This is still Day 1 and all our work is ahead of us.

Being a Software Engineer at AIOS
As a Growth Engineer at AIOS, your fundamental role is to build the products, experiments, and systems that bring new patients to AIOS and help them start treatment.
Our systems serve >200k patients each month. Our agentic workflows autonomously generate >$100k of revenue per day. Bolt, our leading UK brand, is now expanding into new markets, and how fast each one converts is the company’s top priority. We’re hiring four Growth Engineers to make that happen.
Your main focus is conversion. You’ll own funnels from the first click to the first purchase, working in a small team with a Funnel Conversion Lead and a Web Designer. Together you decide what to test, ship it fast, and keep iterating until it converts.
Many of our funnels are conversations. Jesse, our AI agent, talks to every lead, answers their questions and guides them all the way to starting treatment. Some funnels will run entirely through Jesse. You’ll work closely with our Growth Engineering Lead to make Jesse one of our strongest conversion channels.
