@doooyle I thought this was satire but it’s real

@aditya_gan3500 @drpraneetajain More than actually? I am investing in this space to drive solutions for adrenal patients that have been long overlooked

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

@aditya_gan3500 @drpraneetajain Agree + good point!

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

@SwtCharlemaigne @HDTTLDPJBMLN @toobaffled First time I heard that AI can lead to this. Hope you are OK though!

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

@FeonaSwan @DisclosurePod Wow. First time I heard of a story of someone actually 'breaking' the adrenal system through lifestyle. Are there more people with this story?

And, of course, I hope you feel a lot better!

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

@quiet_homeboy Many people get misdiagnosed for AI or diagnosed very late which are both huge problems...

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

@SEPfieldPatient Hey! I just found your profiles and see ur posts about 'adrenal stuff' I think you might like to see what we're building with HVC to advance solutions for these communities!

@alifdotbuild what are your opening hours to come and work

[Adriaan Jacob Brouwer @AdriaanJB_HVC]

✨ Meet our advisor — Dr. Mitchell Geffner.

Ron Burkle Chair at Children's Hospital Los Angeles and Co-Director of the CHLA CAH Center of Excellence. Four decades shaping pediatric endocrinology. 170+ peer-reviewed articles. Past President of the Pediatric Endocrine Society. In 2022, the first U.S. physician ever to receive ESPE's International Outstanding Clinician Award.

As a Strategy Board Advisor, Mitch brings unmatched clinical depth and a patient-first lens that ties directly to our adrenal-first thesis.

"The work doesn't stop at the clinic door, it continues with the families, the advocates, and the research that turns rare into treatable."

🤝 Meet our advisor — Fredrik Debong.

Serial entrepreneur, multiple exits, and founder of mission-focused fund https://t.co/6eYSUWDoVb. Fred brings the kind of pattern recognition that only comes from real skin in the game.

He's shown what's possible when a mission-focused fund goes deep into a patient ecosystem. I want to do for adrenal patients what Fred has done for T1D patients.

Been advising behind the scenes for a while. Now it's official.

"Mission-focused funds have an unfair advantage to win in these markets."

📚 Meet our advisor — Dr. Phyllis W. Speiser.

Chief of Pediatric Endocrinology at Northwell Health and Professor at Zucker School of Medicine. Phyllis has shaped clinical care and research for adrenal disorders worldwide and serves as a trusted advisor to NADF and the CARES Foundation.

As a Strategy Board Advisor, she brings guideline-level rigor and a patient-first perspective to everything we back.

"Progress happens when evidence becomes care that fits real lives."

Mission-focused funds don't just have a mission. The specialization becomes the moat.

Had a great time at a mini-conference organized by Dynamic Therapeutics at Amsterdam UMC. Scientists, entrepreneurs, investors all driving for impact.

Fredrik Debong flew in from Vienna to do a panel with me on mission-focused funds. His fund Nineteen Twenty-One is the prime example; deal timelines that take months cut to hours through deep ecosystem embeddedness.

That's exactly the model I'm building at Homeostasis VC. A mission-focused fund for adrenal patients.

Grateful to everyone in the room. Learning so much. ❤️

🔎 Meet our advisor — Irina Bancos.

Leading adrenal endocrinologist at Mayo Clinic. Irina has shaped clinical practice through non-invasive biomarker development and modern diagnostic pathways for adrenal tumors, cortisol excess, adrenal insufficiency, and CAH.

As a Strategy Board Advisor, she keeps Homeostasis VC anchored in best-in-class adrenal science and real patient impact.

"Earlier, clearer diagnosis changes everything — for patients, families, and the system."

Homeostasis VC has joined REMEDI4ALL's funders network.

REMEDI4ALL focuses on drug repurposing — highly relevant for us. Many adrenal patient groups fall into rare or ultra-rare disease territory. In some cases, treatment pathways haven't seen innovation in 30-50 years. Some have none at all.

Repurposing existing drugs can change that. Proven medicines. Shorter timelines. Faster access for patients who've waited long enough.

REMEDI4ALL gives us access to curated, venture-backable deal-flow that's mission-aligned with everything we're building.

Grateful for the partnership. 🔬

🧬 Meet our advisor — Richard Ross.

World-leading endocrinologist and clinician-founder. Richard took adrenal therapeutics from academic discovery to patient access — founding Diurnal Plc and bringing Alkindi and Efmody to market for CAH and adrenal insufficiency.

Now Emeritus Professor at Sheffield, he continues pushing the frontier of adrenal medicine and next-generation biologicals.

"Real progress is when science becomes something patients can actually receive."

🧠 Meet our advisor — Max Nieuwdorp MD PhD.

Leading clinician-scientist at Amsterdam UMC. Max has built a career pioneering research in metabolism, endocrinology, and the gut microbiome — and translating that science into real-world impact.

As a Strategy Board Advisor, he helps Homeostasis VC back ventures that move from papers to practice.

"Endocrinology is systems biology — and the next breakthroughs will come from connecting the dots."

@CarlaPeeters3 Very obvious.

The mass psychosis of the entire country to get as tanned as possible so that you can hear your colleagues tell you 'wow you are so tanned' for two weeks before you lose all of it and go back to your former self.

@TimurNegru I just love your content bruv. Always great to see these beautiful Andalusian compounds
