About Aios Medical

Our overarching mission is to accelerate the mass-market global adoption of consumer biotech products so every human can live at least 100 healthy years.

Our immediate focus is excess bodyweight. We are increasing the global accessibility of GLP-1 medications to accelerate their take-up to help solve obesity worldwide.

To do that, we’re building an AI-powered clinical operating system: ClinicOS. ClinicOS makes it effortless for consumer brands to easily offer direct-to-patient healthcare, globally. We work with external Brand Partners, as well as using this infrastructure to scale our own internal consumer healthcare brands.

Since we launched Fella Health in the US in June 2021, Fella has positioned itself as no-nonsense weight loss for busy bigger guys. Today, we operate multiple brands across the US & UK — our two biggest are Fella Health (US & UK) & Bolt Pharmacy (UK).

Our infrastructure will have served 100 million patients worldwide by 2035. We’ll then use that direct-to-patient infrastructure to serve next-gen biotech products at-scale to increase the proportion of humans living at least 100 healthy years.

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

How far along are we?

We’ve grown >1000x since Aug 2021, >200x since Aug 2022, >40x since Aug 2023. We’re serving >20k customers with high NPS. We’re >$50M/yr revenue. We’ve been cashflow positive for >24mo.

We’re a young startup and we’re just getting started. This is still Day 1 and all our work is ahead of us.

We're backed by top healthcare & consumer investors:

• Y Combinator

• Global Founders Capital — backed Facebook, Slack, LinkedIn, Revolut, Rocket Internet

• AngelList Early Stage Fund (backed by Naval Ravikant)

• BrandProject (venture-builder behind 2 unicorns)

• The founders of Indeed, Curative (unicorn), Alan (unicorn), Kaia Health (>$300mil valuation), Vouch Insurance (>$500mil valuation), Not Boring (Packy McCormick)

Our cultural standards

These are the core cultural standards to which we hold ourselves & our team members at Fella:

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 fing 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.”*
