It takes an outlier founder with the vision and execution ability to build Super. Samir has stacks of both. phoenixcourt.vc/news/super-s…

So encouraged to read this moving, bravely reasoned statement of impassioned solidarity from Muslim friends and co-citizens . Exactly what is needed right now. Thank you so much. Be assured that we Jews would feel and speak the same way in the face of virulent Islamophobia.

@BioOrbitSpace might look like a space company, but really it's a new infrastructure layer for pharma.

What an opportunity…. Join a ground breaking company

Today the Financial Times reported on OLIX's latest financing round. We've now raised just north of $250M to continue building the first Optical Tensor Processing Units (OTPUs), and deliver them to customers.
We're also publishing the OLIX Compute Manifesto: our view on what it will take to win in inference-era compute. Link in comments.
It is our belief that scaling an SRAM-architecture integrated with photonics can surpass HBM-based architectures on throughput/MW and TCO, and significantly outperform silicon-only SRAM-architectures in interactivity and latency.
We're scaling fast. If you want to work on the most important compute problem of the next decade, we're hiring across London, Austin, San Francisco, Toronto, and Bristol.

Cleo is a pretty special company and Barney is one special founder! Business built with AI/ML before AI was a thing. Now turbo charging.

Getting to $100M ARR was hands down the most brutal thing I’ve ever done.
You start with nothing. No team. No capital. No momentum. And you have to do everything - purely through willpower.
Every $100M after that is dramatically easier and comes much faster.
Adding products, optimising, and launching new geos is infinitely easier compared to finding PMF and reaching the first real scale. By $100M ARR, you have a great team, capital, and a platform to build from.
Starting with just a laptop and an idea and saying “I’m going to build a Google-sized company” is pretty unhinged in hindsight!
Cleo's growth...
$0 → $100M ARR: 94 months
$100M → $200M ARR: 14 months
$200M → $300M ARR: 9 months
$300M → $400M ARR: 6 months (coming soon)
If you’re a founder grinding toward your first $100M... gl! Just know it gets easier, keep going.

Ten years ago, we invested in @faculty_ai at seed, when the team was just ten people.
Today, they announced their acquisition by @Accenture.
A huge moment.
