Numbrs
Swiss fintech unicorn that pivoted from a Mint-style banking app to Bitcoin key storage in a bunker.
Numbrs carries a 2019 unicorn label into a Bitcoin-custody pivot with no disclosed users, revenue, or funding since 2020, kept alive by its founder's family office.
Numbrs started as a personal finance app that let people see all their bank accounts in one place, but that business got replaced by free tools built into banks and AI assistants. The company then shifted to storing Bitcoin private keys in Swiss vaults, but bigger, licensed competitors like Coinbase Custody and BitGo already control that market and have government approval that Numbrs lacks. The one thing that could change everything: if founder Martin Saidler keeps writing checks from his family office, the company survives; if he stops, it likely runs out of money within a year.
A funding round or valuation event from an investor other than Martin Saidler's family office. Would show outside capital validates the business beyond one backer.
Martin Saidler's family office stops or pauses funding, or Numbrs announces layoffs or wind-down. Would confirm the company depends entirely on one funder to survive.
- Raised ~$200M total, hit $1B valuation Sep 2019
- No new funding disclosed since CHF 27M round
- Legacy app had €11B in linked customer assets
- Single point of failure: company survival tied to founder Martin Saidler's continued family-office funding.
- No disclosed user, revenue, or AUM figures for Bitcoin custody business for over three years.
- No external funding round since December 2020, frozen $1B valuation from 2019.
- Bitcoin price down ~49% from October 2025 high as of July 2026 could reduce custody demand.
- Larger regulated custodians like Coinbase Custody and Anchorage offer greater scale and trust with no barrier to entering Numbrs' niche.
| Rival | Direction | Evidence |
|---|---|---|
| Coinbase Custody | losing to | Reportedly holds ~80% of US spot Bitcoin ETF custody assets as of 2026, per onrampbitcoin.com (vendor-claimed) |
| Anchorage Digital | losing to | OCC-chartered institutional custodian operating at scale Numbrs has not disclosed matching |
| BitGo | losing to | Established institutional-grade custody provider with no comparable Numbrs traction data since 2022 |
| Xapo Bank | contesting | Gibraltar-licensed cold-storage-heavy custodian competing in the same self-custody-adjacent niche |
| N26 | losing to | Legacy neobank peer while Numbrs' original aggregation app was still active before its 2021-2022 shutdown |
- Is Numbrs profitable in 2026?
- No profitability data has been disclosed since Numbrs acknowledged in 2019 it had not turned a profit in five years. After its 2021-2022 pivot to Bitcoin custody, the company has released no revenue, AUM, or user figures, leaving profitability unverifiable as of July 2026.
- Is Numbrs still a $1 billion unicorn?
- Numbrs was tagged a $1B unicorn in September 2019 after raising $40M, bringing total funding to roughly $200M. No funding round or valuation update has been reported since a CHF 27M raise in December 2020, so the unicorn label is frozen from 2019.
- Who owns Numbrs?
- Founder Martin Saidler, through his family office and Saidler & Co Finance, has historically been majority shareholder and the primary emergency funder, including leading the December 2020 CHF 27M round. Other past backers include the Investment Corporation of Dubai and Marcel Ospel.
- Has Numbrs had layoffs?
- Yes. In May 2020 Numbrs cut about 62 jobs, roughly 50% of its workforce, after a signed investment round fell through during COVID-19. Headcount fell from a peak of about 150 employees in 2019-2020 to around 70 after its 2022 pivot to Bitcoin storage.
- What does Numbrs do now?
- Numbrs shut down its original Mint-style bank-account-aggregation app around 2021-2022 and pivoted to Bitcoin custody, offering a non-custodial wallet plus encrypted private-key backup stored in a converted alpine bunker near Zug, Switzerland.
- Who are Numbrs' biggest competitors?
- In Bitcoin custody, Numbrs sits alongside Xapo Bank, Casa, Unchained, Ledger, and Trezor, but the dominant players are institutional custodians Coinbase Custody, BitGo, and Anchorage Digital, which operate at far larger regulated scale.
