## Fractile raises $720M at $7B valuation
London-based chip designer Fractile closed a Series C round led by Thrive Capital, Founders Fund, Lightspeed and Redpoint. The funding values the four-year-old company at $7 billion.
## The memory bandwidth problem
Founder Walter Goodwin argues that over 25 years, chip performance increased roughly a millionfold while memory bandwidth grew only about 40 times. This creates a 25,000-fold gap between processing and data access.

## Fractile's three-dimensional solution
Fractile combines custom DRAM and logic in a three-dimensional stack to deliver higher bandwidth than high-bandwidth memory while retaining capacity for large models. Goodwin claims it could make inference up to 10 times faster.
## Anthropic interest and crowded market
Anthropic has expressed interest in becoming an early customer for Fractile's chips. The company faces competition from Nvidia's inference chip launched in March and startups including Etched, MatX and Olix.
## Prototypes, not products yet
Fractile has not released a commercial product. Its first chip is planned for next year. The $7 billion valuation is based on technology and prototypes rather than a product in the market.
## Key takeaway

Fractile raised $720 million at a $7 billion valuation to build AI inference chips designed around memory bandwidth rather than raw processing power.
