**Country:** United Kingdom (London)
**Founder:** Alexander Weber — Founder & CEO
**Background:** finance | verified: True — Fintech/finance. Alexander Weber spent roughly nine years at N26 (a German neobank/digital banking fintech), joining as one of its earliest team members (among the first ten people) and rising to Chief Growth Officer, helping scale the business beyond €200M in revenue, 10M+ customers, and a $9B valuation. He then founded the London-based HealthTech startup Calibre (2025) as Founder & CEO. His core operating background is in the finance/fintech sector via N26.
**Stage / fundraise:** Very early (founded 2025), emerged from stealth April 2026, pre-seed funded. / Closed USD 3.3M / EUR 2.8M pre-seed, April 2026, led by Amino Collective.
**Regulatory trigger:** No public CE/MDR/IEC 62304 or reimbursement milestone disclosed. Product is described as a consumer "causal health navigation" / proactive-care platform combining clinical expertise with causal AI. Whether it positions as SaMD (and thus triggers MDR) is unconfirmed from public sources; treat as unknown rather than asserted.
**Email:** (confidence none) — No published email address found in sources, and Calibre's corporate domain / email pattern was not confirmed from any public source. Per hard rules, not fabricating an address or guessing a pattern without evidence.
**LinkedIn:** https://uk.linkedin.com/in/alexander-weber-83852aa1 **Website:** https://firstwordhealthtech.com/story/7204536
**Score:** 4 -> Tier C
**Hook:** Not recommended for outreach: Calibre is London/UK-based (outside the EU-excluding-France scope) AND already has a senior technical co-founder/CTO (Ben Levy), which removes the OmDev value wedge (embedded senior dev team + dedicated CTO + MDR/IEC 62304 compliance engine at ~3x cheaper than in-house). Keep on file purely as a reference of the ideal FOUNDER profile (ex-fintech CGO, non-technical, very early, just raised) to pattern-match against in-scope EU SaMD startups that lack a CTO.

## Founder & background
Alexander Weber, Founder & CEO. Ex-N26 (early team member -> Chief Growth Officer), scaled N26 beyond EUR 200M revenue — a strong fintech/finance, non-technical commercial pedigree, the single best founder-background signal in the set ([eu-startups](https://www.eu-startups.com/2026/04/uk-healthtech-startup-calibre-emerges-from-stealth-with-e2-8-million-to-tackle-health-guesswork/)). However, he co-founded with a heavyweight CTO (Ben Levy, ex-Elvie/Manual CTO) and a CMO, so the team is NOT thin on engineering leadership.

## Funding & momentum
Emerged from stealth April 2026 with a USD 3.3M / EUR 2.8M pre-seed led by Berlin-based Amino Collective; participation from Daybreak Ventures and Cocoa Ventures plus angels Timo Boldt (Gousto) and Maximilian Tayenthal (N26 co-founder) ([tech.eu](https://tech.eu/2026/04/22/calibre-emerges-from-stealth-with-33m-to-tackle-health-guesswork-through-causal-ai/), [finsmes](https://www.finsmes.com/2026/04/calibre-raises-3-3m-in-pre-seed-funding.html)). Founded 2025 — very fresh and well-capitalized for its stage.

## Product & regulatory
"Causal Health Navigation": combines clinical expertise with causal AI to identify what drives an individual's health and how to change it; positioned as a proactive/preventive consumer health category ([firstword](https://firstwordhealthtech.com/story/7204536)). No public CE/MDR/IEC 62304 or reimbursement milestone, and SaMD classification is unconfirmed — regulatory trigger is unknown, not asserted.

## Pain & buying signals
Weak. Calibre already has an in-house, deeply experienced CTO and engineering leadership (Ben Levy, 20+ yrs, ex-Elvie/Manual), which removes OmDev's core wedge (rented senior dev team + dedicated CTO). Combined with London/UK geography (outside the EU-excluding-France scope), this is not an outreach target.

**Why OmDev fits:** It largely does NOT. The OmDev offer (embedded senior devs + dedicated CTO + MDR/IEC 62304 SOUP/traceability compliance engine, fixed monthly price ~3x cheaper than building in-house) is built for early, raising, non-technical-founder SaMD teams WITHOUT a CTO and facing a CE/MDR milestone. Calibre matches the founder-profile half (ex-fintech CGO, very early, just raised) but fails on geography (UK, out of scope) and on the no-CTO premise (strong technical co-founder present). Tier C — keep only as a reference profile to find comparable in-scope EU startups that lack engineering leadership.
