Probably Genetic offers free at-home genetic testing for people with rare diseases. Patients collect a DNA sample at home, mail it in, and receive physician-reviewed results with genetic counseling and a clinical genetic report. The company funds the tests itself and keeps the data; after de-identification, the aggregated data is sold to research institutions and pharmaceutical companies. Its goal is to help patients get timely diagnoses while funding the program through data-driven partnerships to advance rare-disease research.

Simplify's Take

What believers are saying

  • Caregiver Action Network partnered in May 2025, expanding referrals into rare-disease communities.
  • July 2026 website says more than 50% of users with unexplained symptoms received diagnoses.
  • July 2026 marketing targets 200 million patients with genetic disease, supporting large underserved demand.

What critics are saying

  • May 2025 caregiver partnership shows dependence on sponsor-funded programs and advocacy intermediaries.
  • Data-driven monetization faces privacy backlash because July 2026 FAQ emphasizes de-identified sharing and no PII.
  • If sponsored testing dries up, 17-person YC team loses its only scalable acquisition engine.

What makes Probably Genetic unique

  • July 2026 site offers free exome testing, counseling, and insurance-billed care for rare diseases.
  • Probably Genetic launched patient-initiated no-cost testing in 2018 before many rare-disease competitors.
  • ChatPG combines machine-learning symptom screening with at-home testing and counselor follow-up.

Calm/Storm: 4,5 Mio. Euro 2023 Investiert – Und 2024 Kann Noch Einmal Blutig Werden

Aus Österreich heraus den aktivsten HealthTech-Fonds Europas zu starten, ist eine Leistung, die sich Lucanus Polagnoli und sein Team auf die Segel, pardon, Fahnen, schreiben können: Doch seit 2023 investiert Calm/Storm Ventures nicht nur in Digital-Health-Startups, sondern hat auch einen eigenen Fonds für Startups aufgelegt, mit dem auch in Startups aus anderen Branchen investiert, solange diese von Österreicher:innen (mit-)gegründet wurden. „Mit insgesamt 17 Neu-Investments ist das Portfolio auf 75 Startup-Unternehmen gewachsen. Zusammen mit 21 Follow-On Transaktionen innerhalb des Portfolios wurden 2023 insgesamt über 4,5 Millionen Euro investiert“, so Calm/Storm-CEO Lucanus Polagnoli zu Trending Topics. Man würde besonders oft in so genannte Stealth-Startups investieren, also Jungfirmen, die noch gar nicht auf dem Markt sind. Ein Beispiel ist Mirror, das neue Startup der ehemaligen Gründer von Gorillas, Kagan Sümer und Ugur Samut. Wert wird auf Diversität gelegt; Die Hälfte der Teams, in die Calm/Storm investieret, sind divers, und 30% aller CEOs seien Frauen
