01Health is at an inflection point. The platform is built, revenue is accelerating, and we are moving from a single-specialty company to a multi-vertical specialist healthcare platform - with AI as embedded clinical infrastructure. Our vision is to help all clinicians deliver the latest innovations in healthcare, improving the standard of care for millions of people. Backed by the investors behind Revolut, CityMapper, and Depop - we're scaling fast across the UK and beyond, and are looking for exceptional people to join us on our mission.
Balderton-backed Series A company
90% of UK patients can reach an 01Health–affiliated clinic within 30 minutes
All growth has been inbound, ~50% word of mouth
4.98★ customer rating from the dentists who use us
Aerox (sleep) ready for national rollout to top-performing 01 Partners, with a 300+ clinic waitlist
US expansion live
New verticals being tested and prototyped
We are not searching for product–market fit anymore. We are building our growth engine, and we’re looking for two exceptional people to lead it - one in sleep, one in orthodontics.
We are looking for Growth Hackers who treat marketing as a set of experiments to run, not a calendar to fill. You are a true generalist. You can write a landing page in the morning, ship a paid test by lunch, wire up an automation in the afternoon, and read the numbers the next day to decide what to kill and what to double down on.
You are AI-native: you use AI to do the work of a team several times your size, and you are always building the next system that lets you move faster.
This is a build-from-scratch role with real ownership. You will set the standards, build the playbooks, and have the freedom to try ideas that sound slightly mad on paper. Most will not work. The ones that do will change the trajectory of the business.
We’re hiring two people into this role.
Track 1: Aerox. Aerox is our sleep product, built for clinicians treating snoring and sleep apnoea. We have hundreds of clinics on the waitlist and the product is ready to roll out nationally. Your job is to turn that waitlist into a growth engine: convert warm interest into active clinics, build patient lead gen pipelines from scratch, and get an acquisition flywheel turning. Sleep dentistry is a brand new, fast-growing market and you will be a first mover.
Track 2: 32Co. Our first product focused on orthodontics / clear aligners. To date, growth has been almost entirely inbound and via word of mouth. Your job is to change that: build deliberate, repeatable acquisition for the dentist segments we want most, run lead gen experiments across channels, and help us convert high-volume orthodontic dentists who currently use competitors like Invisalign. This is a commercial, pipeline-facing growth role sitting alongside and working within our commercial teams.
Lead gen and experimentation
Own a constant pipeline of growth experiments across paid, organic, referral, partnerships, and channels nobody has tried yet
Find unfair advantages: loops, referral mechanics, and acquisition angles that compound rather than cost more every month
Instrument everything, so every test produces a clear read and a clear decision
Move our growth from mostly inbound to a deliberate, repeatable engine
AI-native growth
Build AI-powered tools and micro-products that drive acquisition - lead qualification bots, personalised outreach agents, interactive ROI calculators for clinicians, or anything else that drives growth but didn't exist last month
Build repeatable marketing systems and workflows, so output scales without headcount scaling with it
Stay at the front of what AI makes newly possible in marketing, and bring those capabilities in before competitors do
Reporting and optimisation
Own performance reporting end to end, and make data-led calls on where to invest and what to kill
Work closely with sales to align acquisition activity with the customer journey and pipeline
A genuine generalist who is dangerous across growth, content, and analytics, and happy to learn the next thing on the go
Hungry, curious, and fast. You ship, you measure, you iterate, and you do not wait for permission
AI-fluent. You already use AI daily to multiply what you can do, and you are excited by where it is heading
Full of aggressive, unconventional ideas, and comfortable being wrong on the way to the ones that work
Strong instincts for what will convert, with the numbers to back up your decisions
Likely a start-up person who thrives in ambiguity and wants to build, not maintain
Deep interest in healthcare, technology, and helping people at scale
Real impact, every day - your work directly changes patient outcomes. You'll feel it, and so will the people whose care you're improving.
25 days holiday + your birthday off - because no one should work on their birthday!
Outsized leverage and full ownership - real authority today, lasting impact tomorrow; what you build now shapes how this company operates at every stage after.
Grow fast - backed by top VCs and built by the best; you'll be learning from some of the sharpest minds in health-tech every single day.
Vitality Health cover - private medical insurance, because we take care of the people who take care of the business.
Team Perks - enjoy regular team lunches, quarterly socials, and an annual company retreat.
Hybrid working - we all come together three days a week, but the rest of the time, enjoy the flexibility to work from home or our Hoxton office.
JOIN PROTON AND BUILD A BETTER INTERNET WHERE PRIVACY IS THE DEFAULT Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right. Since then, we've built the world's largest encrypted email service (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar - tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, Proton has literally helped save lives. We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 700+ team members across 50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Check our open-source projects here. Purpose of the role We're looking for a Head of Growth to own product-led growth for Proton Mail & Calendar. The focus is on finding and building the mechanisms inside the product itself that drive activation, conversion, retention, and virality, while partnering closely with marketing to align product-led and marketing-led efforts into a single growth strategy. You'll work closely with product, engineering, and marketing to design, ship, and iterate on growth loops, owning the roadmap and the metrics that come with it. What you will do * Own the end-to-end user funnel, including signup, onboarding, activation, free-to-paid conversion, upgrade paths, and retention, and identify where friction or leverage exists at each stage * Design and ship in-product growth experiments (onboarding flows, activation nudges, paywalls, upsell moments, referral and invite mechanics) in close partnership with product managers and engineers * Partner closely with product marketing, influencer, social, and performance marketing teams to develop cross-functional growth strategies that connect top-of-funnel acquisition with in-product activation and retention * Partner with the other product teams on core Mail and Calendar features that maximise retention and LTV * Build and own a rigorous experimentation pipeline, including hypotheses, A/B tests, instrumentation, and clear read-outs that inform both the product and marketing roadmaps * Identify and build virality and network-effect loops (referrals, sharing, collaboration features) that drive organic growth, coordinating with marketing on how these loops are amplified externally * Define the core growth metrics for the business (activation rate, conversion rate, retention/churn, LTV, referral coefficient, etc.) and be directly accountable for moving them * Partner with data and analytics teams to build the instrumentation and dashboards needed to see the funnel clearly and act on it * Synthesize user research and behavioral data into product and marketing bets that improve the funnel, acting as the user's advocate inside planning across both functions * Directly influence the product roadmap, treating growth as a core input into what gets built next Job requirements * Proven experience owning product-led growth at a SaaS or consumer tech product, having built or scaled onboarding, activation, conversion, or retention systems from inside the product * Experience working cross-functionally with marketing teams (product marketing, performance, social, influencer) to align product and marketing growth efforts * Fluency in experimentation: designing tests, understanding statistical validity, and knowing when a result is actionable versus noise * Strong technical and analytical fluency, comfortable in product analytics tooling, and able to speak credibly with engineers about implementation trade-offs * Experience building or scaling virality and referral mechanics, ideally in a product with network effects * Leadership by influence, with the ability to align product, engineering, marketing, and data stakeholders outside your reporting line around a shared growth vision * A strong bias toward shipping and testing, matching Proton's culture of hands-on builders * A cost-efficient, scrappy mindset, as Proton is bootstrapped and wins through smart execution rather than big budgets * Comfort with ambiguity and a willingness to make bold, high-conviction calls about where the growth potential lives in the product WHY PROTON: * Work that Matters: millions of people trust Proton with their privacy. We answer only to our users — not advertisers, not investors with conflicting agendas, not governments. The work you do here is real, and the impact is measurable. (read more about our impact here) * A great Team: Our team is diverse, collaborative, and tight-knit with people coming from all walks of life, including many of the world’s top academic institutions and organizations, such as MIT, Harvard, Stanford, Caltech, Cambridge, and ETH. * Technology: you'll get the right hardware and the right software you need to do your best work. * Learning & Development: we invest in your growth because sharp people make us better. Proton is one of the fastest ways to accelerate your career because you'll be thrown into real challenges, with real ownership, from day one. * Employee Benefits: your wellbeing isn't an afterthought. We offer strong health coverage, solid retirement options, generous leave, and wellness support so you can bring your best self to work every day * Stock Options: at Proton, we all have the opportunity to be owners of the company. From day one, you have a real stake in what we're building. When Proton wins, you win. * In-Person Collaboration: Amazing things happen when passionate, smart, and purposeful people get together in the same room. With offices across Geneva, Zürich, Barcelona, London and more, you'll spend most of your time collaborating face-to-face with people who genuinely care about what they're building * Food: Lunch and snacks are on us every day in our offices so you can focus on the work and not on what's for lunch. * Transport: getting to the office shouldn't cost you. We cover public transport, bike allowances, or parking, whichever works for you. * Flexible Working: you own your schedule. Set hours that work for you and your team — because outcomes matter more than when the clock says you started.
