# Tendrils Raises $30M Funding Led by Benchmark to Redo the CPU

> The Cambridge chip startup, founded this year, is building a processor with thousands of parallel cores and its own open-source language, Vine.

**Tendrils, a Cambridge chip startup founded in 2026, has raised $30M in a round led by Benchmark to build a general-purpose processor with thousands of cores running in parallel.**

[Tendrils announced the round on its blog](https://tendrils.co/blog/2026-11-10/30m-raised) on 10 November. Benchmark general partner Jack Altman, formerly chief executive of Lattice, has joined the board.

The UK Sovereign AI Fund invested, alongside Visionaries Club, FR8, Antimatter, Cloudberry VC, Conviction, Embassy Ventures, SV Angels and several angels. Early backer Visionaries Club describes it as a seed round.

## What is Tendrils building?

Tendrils' starting question is blunt: what if we redo the CPU?

The company argues that today's processors still carry design choices from the 1970s, built for sequential, single-core programs. To stay backward compatible, chipmakers stack on cache coherency protocols and complex reorder buffers, which it says now limit performance.

Its answer drops two long-standing assumptions: shared mutable memory and linear streams of instructions. The aim is a chip where thousands of cores can work at once without programmers hand-assigning work to threads.

## What is Vine?

Hardware alone will not get developers to change habits. So Tendrils is also building [Vine, an open-source programming language](https://github.com/VineLang/vine) designed from the start for parallel-first chips.

Vine is based on interaction nets, a model where small local rules run in parallel without locks. It is still experimental.

That is the hard part of the bet. Developers have written for shared-memory machines for decades, and Tendrils needs them to write differently before its silicon can shine.

## Who is behind Tendrils?

The company's website lists a small team that includes Nils Cremer and Hugo McNally, without giving roles. Tendrils has not disclosed headcount, a valuation, a product date or any performance figures.

Its blog post says the chips of the future will come from close collaboration between hardware and software engineers, and it is hiring for both.

## Why did Benchmark lead?

Benchmark has form in unusual chips. It backed Cerebras at Series A in 2016, long before AI made wafer-scale processors fashionable.

The wider case is that AI agents run many steps of inference and tool calls, which pushes more work back onto general-purpose processors. A CPU that scales across thousands of cores would fit that shift, if it works.

## What this means for UK founders

Cambridge keeps producing hardware companies that US investors compete to back. Tendrils follows London's [Fractile, which raised £577.4m for AI inference chips](https://bizztor.com/news/fractile-raises-577-4m-series-c-for-uk-ai-inference-chips/), and Oxford's [Salience Labs, which raised $125M for photonic chips](https://bizztor.com/news/salience-labs-125m-series-b-photonic-ai-chips/).

The Sovereign AI Fund's presence matters too. A £500m government vehicle now regularly sits beside top US firms in early UK chip rounds, which gives British deep tech founders a domestic co-investor at the riskiest stage.

You can track how the region compares in Bizztor's [Cambridge startup funding data](https://bizztor.com/uk-funding-data/cambridge/).

For Tendrils, the next milestone is evidence: a working chip, a compiler, and numbers that show parallel-first design beats adding more cores to old architectures.
