This week's big theme

Pattern Shift

Every week I review dozens of health tech stories to curate this newsletter and recently I've noticed something has shifted. Almost every story is a partnership.

This week alone: Garmin and Natural Cycles, Heidi and PortmanDentex, Lucis and MindDay, Function and Getlabs.

Founders and investors have figured out that the right partnership unlocks an entirely new feature set and customer base faster than building ever could.

Which raises the question: does this reshape what the best founders look like?

Technical capability is becoming a commodity. The founders who win from here will be the ones who can sell, build trust and open doors. Commercial thinking is the new product thinking.

Getting the right people with this skillset is now a higher priority than hiring the best engineer you can afford.

In this week's episode Dan Strang, Co-Founder of Coopah, talks about how just months after launch with almost no customers, a chance conversation led to them becoming the official training app of the London Marathon.

One partnership changed everything.

Industry News

Heidi X PortmanDentex to bring AI scribe to Dentistry

Heidi has signed a two-year deal with PortmanDentex, one of the UK and Ireland's largest dental groups, to deploy its AI clinical scribe across the network. Around 60 new clinicians are going live each month, following a pilot that cut admin time in practices across both markets. (heidihealth.com)

Why it matters: If you're building for clinical settings, this is the deal structure worth studying. Pilot first, prove it works, then roll out at pace. The buying decision sits at group level - but 60 clinicians a month choosing to use it suggests the frontline validation is there too.

Garmin X Natural Cycles for Fertility Tracking

Compatible Garmin smartwatches join Oura and Whoop in syncing overnight temperature data directly to Natural Cycles, the FDA-cleared contraceptive app, removing the need for a separate thermometer. (lifehacker.com)

Why it matters: Garmin ships over 4 million devices a quarter. That's a lot of new users funnelling into Natural Cycles' algorithm, which gets more accurate as its dataset grows. More evidence hardware partnerships are becoming a distribution strategy in their own right.

Lucis X MindDay to Connect Blood Testing with Mental Health

Lucis, the YC-backed blood testing platform tracking 160+ biomarkers with over 1 million tests done since 2025, has partnered with MindDay, a mental health app with over 2 million downloads across Europe. The two are combining blood data and mental health tools into a single prevention platform - your body and your mind in the same product. (linkedin.com)

Why it matters: Two startups combining data rather than each trying to build everything from scratch. Partnerships like this shorten the road to a full prevention product for both parties. The model is worth watching - partnership as a faster route to breadth than building.

Unilever Acquires Grüns for $1.2bn

Unilever has agreed to acquire Grüns, the US greens supplement brand founded in 2023, for $1.2 billion in another huge CPG deal following Huel and Bionic. The company hit $300 million in annualised revenue in under two years, built around a daily gummy format designed to be something people actually stick to. (unilever.com)

Why it matters: Three years old. $1.2bn exit. Grüns built around the belief that adherence is the real problem in supplements, not the formula. CPG majors are now paying serious money for consumer health brands with retention that holds.

Function Acquires Getlabs to Bring At-Home Blood Draws to Members

The preventive health platform valued at $2.5 billion, has acquired Getlabs, which sends licensed phlebotomists directly to members' homes or offices. Members can now choose between visiting one of 2,000+ labs or booking an at-home blood draw, with the same tests and results either way. (fitt.co)

Why it matters: Getting to a lab is the main reason people don't test regularly. Remove that step and you change the behaviour. For anyone building preventive health products, this is a useful proof point that removing friction is worth more than adding features.
