Thought Machine, led by former head of text-to-speech group at Google Paul Taylor, comes out of stealth, launches blockchain-based banking backend Vault OS
Despite holding the vast majority of the world's wealth (or perhaps because of that), banks aren't exactly hotbeds of cutting-edge tech …
Context & Ripple Effects
When Paul Taylor left his post running Google's text-to-speech group to found Thought Machine, the bet was that bank core systems were ripe for replacement rather than patching — hence Vault OS, a blockchain-based backend pitched as a ground-up rebuild. The stealth exit in 2016 was the opening move in what became one of the better-funded runs in banking infrastructure: an $83M Series B in 2020, a $200M Series C at a $1B+ valuation in late 2021, and a $160M Series D at $2.7B by mid-2022 with 35+ banks on the platform.
The launch also landed in a competitive window: within a year, 10x — founded by Barclays' former CEO — raised a $46M Series A against the same thesis that large banks' legacy stacks could be displaced wholesale, confirming that ex-incumbent operators and ex-Big Tech engineers were converging on the same target.
First-order effects
- Banks evaluating core-system replacements gain a new vendor option built from scratch on blockchain rails, fronted by a founder whose Google engineering credentials are the pitch's credibility anchor.
Second-order effects
- Thought Machine's subsequent fundraising trajectory — B2B2C distribution, then unicorn status, then a $2.7B mark — forced the category into investor view, with 10x raising $46M the following year to attack the same legacy-modernization budget.
Third-order effects
- If the pattern holds, core banking consolidates around venture-backed platform vendors selling infrastructure-as-a-service, and notably Thought Machine's own framing shifted from 'blockchain-based' at launch to 'cloud-based' by its growth rounds — suggesting the technology label mattered less than the replace-the-core pitch itself.
The trend: Bank core infrastructure is shifting from in-house legacy systems to venture-funded cloud-native platforms founded by outsiders from Big Tech and incumbent banking alike.
