What Frontier Computing does
Frontier is first to grow biological brains at scale, serving biological neural nets with substrate-level colocation of memory and compute, enabling highly cost effective training of large parameter count models. While academia has traditionally been limited to ~1M neurons in vitro, Frontier has built a pathway to scale to 100M+ neurons by circumventing traditional scaling challenges in biological culture, demonstrating this strategy's functionality by training a biological brain using this scaling primitive to play Frogger. Frontier is now growing exascale compute clusters to produce substrates capable of long-horizon language reasoning while operating at much higher sample efficiencies than traditional architectures, and collocating memory with compute to enable significantly larger parameter counts than would be tractable for training within traditional compute clusters.

Frontier Computing
Growing biological brains for ML training at scale
We're building biological brains in vitro, scaling cultures to 100M+ neurons, and using them as physical compute substrates for machine learning training tasks. Our system has already demonstrated training a biological neural net to play Frogger. Now we're scaling to make these biological compute clusters large enough for long-horizon language reasoning, with better sample efficiency and bigger model capacity than traditional hardware.
London, England, United Kingdom. The company would continue to be based in London after YC.
London has a strong pool of talent and access to both biotech and computing resources. We'll stay here to keep building and scaling the team.

Frequently Asked Questions
Is this the real Frontier Computing YC application?
No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Frontier Computing's public data (launch notes, founder backgrounds, product description). It shows how a company like Frontier Computing would present itself to YC, not the text they submitted.
