About AIOS

AIOS is building the first vertically integrated AI doctor in Europe.

We’re at >$250M ARR, serving >100k/mo patients, growing >10x YoY. We’re Europe’s fastest growing healthcare company. We’re profitable.

As our wedge into the European healthcare system we’re using GLP-1s, the fastest growing consumer product in history. We’re the only AI-native GLP-1 provider in Europe.

Our master plan:

• Step 1 → $1Bn/yr: Over the last 12 months we've grown 40x to >100k UK GLP-1 patients. In 2026, we’ll hit $1Bn/yr and become #1 GLP-1 provider in UK.
• Step 2 → $10Bn/yr: Blitzscale Europe. Become Europe’s largest GLP-1 provider by acquiring, retooling, then rapidly scaling regulated infrastructure across the top 10 EU markets, just as we did in the UK.
• Step 3 → $100Bn/yr: Use our scale to vertically integrate across agentic patient care, autonomous prescribing, robotic dispensing, and dark factory manufacturing of medication. We'll be the first and only vertically integrated AI doctor in Europe.

TLDR = 2026-2030 is the blitzscale landgrab until the semaglutide patent cliff, then we vertically integrate and own the whole value chain. The only way to keep up with this scale is to replace all marginal human time with AI.

Our infrastructure will have served 100 million patients worldwide by 2035. We’ll then use that infrastructure to deliver next-generation healthcare products at mass scale for low cost so every human can live at least 100 healthy years.

In so doing, we’ll become the world’s first trillion-dollar healthcare company.

We’re a young, founder-led startup. This is still Day 1 and all our work is ahead of us.

The opportunity as Head of Product Growth (Referrals & Viral Loops)

We’re building a world-class team.

As Head of Product Growth at AIOS, your fundamental role is to engineer viral growth. I expect us to reach >0.3 30-Day K Factor (our Primary KPI). This is critical work for us to scale from 100k active customers today to 10 million customers by 2030.

You’ll start by taking over our existing referral program and rebuilding it into a true viral growth system. You’ll lead a team of engineering + design, and work closely with the CEO. You’ll ship daily, test aggressively, and use AI tools to prototype faster than a normal product team thinks is reasonable.

Over time, your work will broader to touch every product surface that can help viral growth: referrals, invite loops, UGC, social sharing, gifting, visible product moments, freemium/pre-conversion products, and weird ideas we haven’t thought of yet. You’ll build a cracked team under you to execute this.

This is a founder-builder role. You’ll act with high autonomy. We want someone who thinks distribution is a product problem, moves fast, has strong consumer taste, and knows how to create loops that make people want to share.

If you nail the role, you’ll continue to lead everything in Product Growth. If you’re truly excellent, you’ll be a leading candidate for our future CPO or CGO roles.

This is a full-time, fully remote role, and you’ll work mostly async in the timezone of your choice. You must be around until midday Pacific Time every weekday to have enough crossover with me.

This is a senior role. You’ll report directly to me, Richie :) (our CEO). I’m intense, so you’ll also be intense. You’ll work long days and regularly work weekends.

You’ll work most closely with me (Richie, CEO), our VP Growth (Rick Singh), our Head of Product (Ben Dowdle), our VP Engineering (Gzim Helshani).

Key responsibilities

Areas

📈 ”A startup is a company designed to grow fast. The only essential thing is growth. If you get growth, everything else tends to fall into place.”

Overall: You’ll build viral loops that cause customers to bring in other customers. You’ll measure this primarily via 30-Day K Factor.

• Referrals: You’ll understand our existing referral program, then rapidly improve it via experiments. It’s not unlikely you rip it up to rebuild the foundations.
• Pull Virality: Create product experiences that are better when customers invite friends.
• Push Virality: You’ll turn our customers’ offline touchpoints into a billboard for the product.
• UGC: You’ll activate real customer stories, screenshots, milestones, and before/afters so our customers organically share content with their friends.
• Product as Marketing: You’ll get imaginative in the freemium experience (e.g. shot-tracking app) to get users into our ecosystem.
• Organic WoM: You’ll get imaginative on what we can be doing to trigger delight and tribal affinity so customers instinctively just want to tell their friends about us.
• Analytics: You’ll make sure everything is tracked. You’ll own the decision on what stack to use and guide its implementation.

KPIs

Need to have

• Experience: Either you have 5+ years in product growth in high-growth D2C companies, with clear ownership of referrals & viral loops…or you’ve founded a viral social app and built this from the ground-up. I have a strong preference for people who understand & enjoy the scary speed of a high-growth startup.
• Analytics: You’re maniacal about your metrics. You care a weird amount about your analytics stack.
• Experiments: You’re proactive when crafting experiments and have a clear process for generating & prioritizing ideas.
• Loops: If you’re not native in consumer loops, you’re ngmi. You think of distribution as a product problem.
• Design: You’re comfortable with design principles & wireframing so can work closely with design to get what you want into pixels.
• Engineering: You’re sufficiently technical so code doesn’t bother you. You see turning your ideas into pixels as part of your remit, not something separate from you.
• Shipping: You’re excellent at leading product from idea to prioritization to launch to success. You don’t easily get blocked.
• Zest: You just get consumer. You have strong taste for consumer products and can tell when a flow feels dead, cringe, slow, confusing, or magical.
• Strategy: You don’t get lost in the weeds and you always make sure we’re taking the required big swings. If not you, who?

Nice to have

• Agentic: You're a doer. You’ve been pulled into important problems, taken risks, excelled in new areas. You've likely founded something in the past and it’s likely you want to start your own company in the future.
• Background: You likely have technical background (data/engineering/design) mixed with exposure to real-world growth in consumer. You love AI tools because now you can do more yourself.
• Systems: You think in and build out systems. In solving a problem you recognize the underlying system, then focus on improving the system itself to fix the true cause of an issue.
• Team: You hate incompetence as much as me. You run a team of strictly A-players, and you truly mean it.
• Excellence: You’re annoyingly capable at meta skills. You’re an autodidact with impressive speed and resourcefulness. You’re highly organized and can complete multiple projects concurrently. You calmly handle uncertainty and rapidly changing situations.

Our cultural standards

We aim to make this your life’s work. This should be the most challenging, most rewarding role of your life. Accordingly, these are the core cultural standards to which we hold ourselves & our team-members:

1. Belief in the mission: We will have served 100 million patients by the end of 2035 and we transform the life of most patients who join. We have a lot of work to do. We are obsessed with our patients and are dedicated to the mission.
2. Unwavering integrity: We are at the frontier, so we often live in ambiguity with no trodden path. When we can’t look to others for guidance, we must maintain impeccable ethics and unwavering integrity.
3. Only the paranoid survive: Bad sh*t is coming. By joining us, you’re choosing to sail straight towards the storms with unhesitating conviction. However much we’ve already done, however far we’ve already come — it’s still Day 1 and all our work is ahead of us.
4. If we’re average we fail: We are only interested in “insanely great”, a focus on the quality of our execution that in everyday life would be considered pathological. We have a dedication to excellence and reject incompetence.
5. Commitment to candor: That which can be destroyed by the truth should be. You get full transparency from the company and the company expects full transparency from you. We never say anything about someone that we wouldn’t say to them directly. We give feedback with love and do not need to protect people from fleeting physical sensations.
6. A maniacal sense of urgency: We execute at an intensity that most people think is impossible. Speed is critical and we need things done yesterday. We all work very hard and in such a competitive world there really is no other way to win.
7. Enduring frugality: We are frugal. We hate being wasteful and we are anti-luxury. A culture of cheapness keeps us young. We spend our cash wisely & carefully — in a way that would make our grandmas proud.
8. Bulldozing barriers: The world is malleable and we shape it. We truly believe this and act accordingly. We are relentlessly resourceful and are at the mercy of no-one but ourselves. You’ll be shocked how capable you are and how much you can achieve.
9. Keep your head down: We’re boring people doing exciting work. We don’t chase short-term status — we ignore short-term dopamine hits and focus on what matters. Outsiders will underestimate us and we revel in that.
10. The power of focus: We live in a world of power laws and we cannot overestimate the unimportance of practically everything. Know your One Thing, and nail it.

🎯 *“You just build a f**ing amazing experience. Make each step amazing. Make every decision in the long term interest of the customer. Give the customer massively more value than you take.”
