Banking tech firm 10x, founded by the ex-CEO of Barclays, raises $46M Series A to help modernize large banks with legacy infrastructure
Context & Ripple Effects
When Tide raised its Series A to attack big banks with a mobile-first SMB service, the threat to incumbents was front-end competition. 10x, founded by Barclays' former chief executive, attacks from the other side: it sells large banks the infrastructure rebuild they would otherwise struggle to fund internally, and its $46M Series A is the earliest funding milestone on record here for that approach.
The bet paid forward: four years later the same company raised a $187M Series C, by which point a whole vendor category — Thought Machine's B2B2C banking platform, Amount's $99M round at a $1B+ valuation — had formed around selling modernization to established banks rather than replacing them.
First-order effects
- Large incumbent banks gain a credible, insider-led vendor for replacing legacy cores, shifting the build-vs-buy calculus toward buying.
- 10x gets the capital to move from pitch to platform delivery inside banks whose own IT budgets have historically favored maintenance over replacement.
Second-order effects
- Thought Machine and Amount now compete for the same incumbent modernization budgets, pushing the category toward differentiated positioning — Thought Machine via a B2B2C model, Amount via helping banks compete with fintechs directly.
- Challenger banks like Tide keep raising money to peel off customers, which is precisely the pressure that makes incumbents willing buyers of 10x-style platforms.
Third-order effects
- If the pattern holds, banking stratifies into licensed institutions at the top and a competitive SaaS infrastructure layer beneath them, with core technology supplied by vendors rather than built in-house — a structure the later mega-rounds in this coverage suggest was already consolidating.
- Ex-bankers founding vendors becomes a repeatable playbook: regulatory and operational credibility, not just software, is what unlocks incumbent sales cycles.
The trend: Bank core modernization is turning into a funded SaaS category where former bank executives sell incumbents the infrastructure rebuild that fintech pressure makes urgent.
