CEO of @griffinbank - the bank you can build on. Wonderfully youthful in spirit - considering.

Flow has raised a $50M Series B at a $750M valuation, co-led by Antonio Gracias (Valor) and Gavin Baker (Atreides) with Sequoia Capital, Roelof Botha (SpaceX, Block), and more.
When I became a mechanical engineer, I wanted to invent. In reality, 90% of the day to day execution work (CAD, excel, sim) was digital manual labour. That’s about to flip. The engineer’s role will change more profoundly than at any point since the invention of CAD, with humans focusing on invention, architecture, tradeoffs and judgement calls, and agents taking the grunt work.
Anduril, Joby, Stoke Space, Rivian & many more - Flow is now the default platform for requirements and verification for frontier hardware teams. But it’s not just next-gen anymore. Industry giants including General Motors PPU and Volkswagen & Rivian’s joint venture (RV Tech) are reshaping their core development practices with Flow’s AI.
The revolution is just starting. Models are getting better quickly at CAD, analysis, simulation, and tool use. In the next year, AI will move from integrating the work to doing the work.
One day, this shift won't just enable us to iterate faster, it will enable us to design a class of products that we could not have dreamt of before.
We’re hiring.
This would be great for small banks and terrible for the big ones, amusingly enough. Small banks are the only ones who need to pay high rates today because they don’t benefit from the safety premium of being TBTF
Fascinating.
Chief Economist at Apollo: agents could cause a bank run by sweeping household cash into accounts paying 3-5% instead of the 0.1% national average, causing banks to lose a large share of their cheap deposits.

I continue to be genuinely astonished at how bad the "Ask AI" feature is in @Superhuman. For a product that is otherwise so perfect, it's unbelievable to me that this is allowed to continue to be awful.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution

The "whiteboard defense:" I should be able to pull you aside at any moment and ask you to explain any customer-facing system you've shipped. You should be able to clearly explain how it works and defend the decisions you made. This is my benchmark for responsible AI usage.
I don't expect line-level familiarity with the code. I don't care if you remember the exact function name or implementation detail. You may not even know it. I don't care.
But if I ask "why did you do X instead of Y?", "what happens if this actor behaves maliciously?", "what data structure did you use here and why?", or "where does this fail?" you should be able to answer confidently.
For PoCs, demos, experiments, whatever: I don't care. Generate 100% of it and understand none of it. Speed over quality every time in those specific scenarios.
But if you're shipping customer-facing work, you can't be shipping things you don't understand at a high level.
I know @Benji_Fernandes personally. He's an incredible founder (and friend) who's built an incredible business - a global business, but one headquartered in America.
It is not in America's interests to keep people like Ben out.
It's not in anyone's interest.
America spent ten years turning a Tanzanian teenager into the founder of an American company.
Then it exported him.
I wrote about it for the @nytimes today. Thread 🧵

Of course the counter to this view would be the Don Valentine view that nothing Sequoia invests in should have the potential to make them less than $100M. It’s hard to pitch both the potential and focus on something small at the same time!

What’s the biggest difference between fintech in the UK and the US?
“In the UK, bankruptcy is treated as a moral failing.”
David Jarvis, Co-Founder & CEO, @griffinbank.
“The UK has actually really strong digital infrastructure relative to other markets.”
Lisa Jacobs, CEO, @FundingCircleUK
“There is still a lot that needs to be done in terms of encouraging adoption of card payments.”
Luke Griffiths, CEO UK, @SumUp.
Three perspectives from leaders building across fintech, payments, and financial infrastructure.
@sxswlndn, the discussion explored how culture, regulation, infrastructure, and adoption continue to shape innovation on both sides of the Atlantic.

"due diligence", my brother in christ it had no board of directors, no cfo, no head of risk and was incorporated in antigua and barbuda. 2 mins of googling would have got you there.

The most important thing that came out of Standard Treasury was serving as the kernel of inspiration to @Venantius to found @griffinbank, and @ctdean and @jimbru to found @treasuryprime. Ideas are cheap, execution is everything -- and both executed!

About once a week, people will ask to meet with me and then pitch the scammiest, most evil product and then be like “how can I make it go viral?” and I just say “find god” and hang up.
My fellow tech nerds: what do you recommend in terms of videoconferencing gear for meeting rooms?

Is Microsoft trying to acquire Dairy Queen???
Today Microsoft announced they're changing the way they name and label threat groups. The new naming convention now aligns with "the theme of weather"
The new names are absolutely ridiculous and we are having a difficult time taking it seriously
See attached images for examples

Spend less time on "two-way door" decisions than "trapdoors." If the decision is reversible, the cost of analysis paralysis is often worse than making the wrong decision and reverting.
