The Hard Tech Era Is Here. Flow Is the Way Out.
News – 12/08/25
Last week, Mike Isaac of the New York Times declared the arrival of Silicon Valley's "hard tech" era: a shift from social media and snackable apps to artificial intelligence, advanced hardware, and serious engineering problems. He's right: the age of Web 2.0 is over.
But for some of us, the hard tech era started a while ago.
We didn’t set out to build another app or feature. We set out to solve a real problem: why hasn’t CPU performance kept up with the rest of computing? Why are we still relying on outdated scaling strategies that add complexity without delivering meaningful gains?
That question led us to the Parallel Processing Unit (PPU).
It’s not an AI accelerator. It’s not an afterthought. Its CPU is a co-processor that integrates directly with the CPU to execute general purpose parallel tasks.. No bottlenecks. Just architecture designed to scale the way modern workloads demand.
In early benchmarks, our PPU demonstrated up to a 100× performance gain with workloads that are optimized for PPU using the same benchmark pattern, same workload, and scaling from 16 to 256 processing units and beyond. For full details, reach out directly.
But this isn’t about chasing numbers. It’s about rethinking performance from the inside out.
The new tech era comes with heavier workloads, tighter timelines, and higher stakes. Engineers are being asked to do more with less, to squeeze performance out of already maxed-out systems. That’s the real challenge of the “hard tech” era.
Flow’s mission is to make that challenge easier.
- Easier to scale
- Easier to develop for
Hard tech doesn’t have to mean painful tech. We believe the best architecture should feel effortless on the outside even if it’s doing something radical underneath.
That’s what we’re building.
We’ll be in Silicon Valley soon for HOT CHIPS 2025 (August 24–26, Stanford University, Memorial Auditorium) to showcase early PPU performance results at our table and meet with engineers, analysts, and industry leaders.
