Show Notes
Callosum just raised $100m led by Atomico, Plural and DCVC. It's one of the largest seed-stage rounds in UK history, coming just five months after Callosum came out of stealth. Callosum builds software that lets AI run across many different types of chips at the same time, making it faster, cheaper and more capable.
Danyal Akarca is Co-founder at Callosum. He believes AI can only have a real economic impact once it becomes cheaper and faster to run, and that's exactly what Callosum is built to do.
