Benchmark Wins Hot Race to Back Chip Startup Tendrils Compute

Newcomer reports Benchmark beat rivals to lead a new round for UK chip startup Tendrils Compute, with sources citing talks of a fast follow-up above $1 billion.

According to Newcomer, Benchmark has won out in a hot competition to lead a new funding round for early-stage chip startup Tendrils Compute, citing multiple people familiar with the matter. Neither round has previously been reported, and Benchmark declined to comment. The deal is the latest in a wave of big VC bets on chips, a sector that gave Silicon Valley its name but has long been out of favor as investors concentrated on software and networking.

The small Tendrils team, led by Nils Cremer and based in Cambridge in the U.K., is betting that general-purpose chips based on an obscure graph-based computing model called interaction nets will let it scale without the coordination and cost problems of contemporary multi-core CPUs, Newcomer reports. The thesis is that as AI agents complete multiple steps of inference and tool calls, CPU speed may become a new bottleneck — a different angle from the inference-ASIC startups dominating headlines. That makes Benchmark's choice notable: rather than another specialized inference chip, the firm backed a contrarian general-purpose architecture from a little-known U.K. team, and beat out competing investors to do it.

Benchmark has been on the leading edge of the new chip enthusiasm. Newcomer recounts that in 2016, partner Eric Vishria co-led the Series A in Cerebras Systems — Benchmark's first hardware investment in ten years, a meeting Vishria almost skipped — and the firm saw a 20.5x multiple when Cerebras went public this spring. That success, combined with relentless AI compute demand, has convinced VCs there are plenty of returns in chips. Newcomer's roundup of recent deals: Etched doubled its valuation to $21 billion on a fresh $700 million raise in August; Fractile is in talks to raise at a $6.5 billion valuation after an Anthropic supply deal; OLIX raised $312 million at a $3.3 billion valuation; Euclyd and Delos Data each announced nine-figure hauls in September; and Volantis Semiconductors raised $88 million from Lachy Groom and Abstract Ventures the same morning.

Chips remain notoriously capital-intensive and cyclical, with long development timelines — Newcomer notes they are 'not for the faint of heart,' pointing to Cerebras, which went public in May at $185, traded as high as $386, and now sits close to its offering price. VCs are getting creative about sharing risk: Newcomer relays that Coatue and chipmaker MatX have been in talks to form a multi-billion-dollar joint venture to help finance memory purchases and manufacturing capacity, per The Information. Gradient managing partner Darian Shirazi summed up the bull case to Newcomer: chip startups 'have a massive tailwind from capex build-out' and 'probably will all do well.' For Tendrils, the immediate next step is the reported fast follow-up raise that could push its valuation past $1 billion — while adjacent platforms like Get Access, which Newcomer-adjacent coverage via IndiaIPO says pools individual investors into late-stage rounds, show how far private-market appetite for AI-era infrastructure has spread.
