Graphcore. Semiconductor company doing accelerators for machine learning, based in Bristol. Raised $200m at a $1.7bn valuation in 2018.

> edit: I'll also take websites, has the UK got any big website companies? Seems like our biggest are Rightmove and Autotrader

Hopin (virtual events; raised about $1bn)

Cazoo (online car sales; about 2k employees)

Deliveroo (food delivery; market cap of about 1.6bn)

Snyk is now apparently Boston based, but was founded in London (cybersecurity); this is a common issue for the European startup space, but perhaps especially so for the UK since startups here tends to target English-speaking markets from the start, in that the incentive to move the companies to the US are pretty significant.

Revolut, sort of. Bank license in Lithuania, founders are Russian and Ukrainian, but headquartered in London.

EDIT: Babylon Health. "Online first" healthcare provider offering both NHS and private GP services via app/video as the first instance (with offline facilities to complement with face to face examinations when needed). About 2k employees; took about $550m funding at a $2bn valuation in 2019

On a serious note: can we determine if any of the Ukranian AIDE went into / through this 'bank'?

The City Of London is the money laundering capital - with all their insturments pointing to the companies/countries of the Panama Papers and the other laundering/tax evasion scandals....

We've got Creative Assembly (owned by Japan-based Sega), Rockstar North (previously DMA Design and founded the GTA Srtries, now owned by US-based Rockstar ofc), Jagex (owned by a US PE company), and a whole host of others mostly now owned by US companies.

There's a piece of wisdom floating around that the UK is actually really good at building tech and tech-adjacent companies, bu really bad at scaling them beond a certain point. We don't have the BigTech companies China and the US do (nobody does, really), but we're a pretty open economy, so lots of promising companies get acquired before they hit _big_.

There was Microfocus: https://www.microfocus.com/en-us/home They owned SuSE at one time. But MicroFocus now have owners outside the UK.

And there was Autonomy: https://en.wikipedia.org/wiki/HP_Autonomy Bought by HP, leading to lots of controversy and legal wrangling when they did get what they had expected.

I guess it's a migration path for people getting rid of big iron but unable or uninterested in getting rid of the code they ran.

Definitely deserves a mention as it at least has quite big mind share.

And Frontier: https://www.frontier.co.uk/ Who develop various games including, possibly most famously in these circles, Elite Dangerous.

(Admittedly, that list is using a definition of 'startup' broad enough to include the UK's second-largest energy supply company)

The only ones are Dyson and perhaps ARM which are the long lasting ones the UK has made.

Monzo, Wise, Starling and Deliveroo are the latest 2010 cohort the UK has made and that’s about it.

The latter cohort may die out or get acquired by FAANG or run out of money and shut down.

Compared to the US, the UK keeps selling their companies abroad rather than acquiring them. The US keeps creating more and more successful tech companies.

Once ARM chose to IPO in the US I knew it was completely over.

Even the LSE is part owned by the US (Microsoft), the UK is slowly giving away their technological sovereignty, not exactly the tech world leaders they keep saying they are.

It is a real shame.

Yes thats a good way of putting it

* Renishaw. Precision measurement and manufacturing. * Spectris. Scientific instruments. Precision components. * Oxford Instruments. All sorts of high-tech stuff used in science and research

Rolls Royce aerospace is pretty cool. There are some defence related companies that do tech stuff. Radar, guidance systems, battlefield comms, that sort of thing. Formula One tech is mostly British. MclLaren, Red Bull Racing, Mercedes are all UK based.
