Tendrils completes $30 million seed round funding, aiming to build a general-purpose processor capable of running thousands of cores in parallel.

November 11 - Cambridge semiconductor startup Tendrils has completed a $30 million seed round of financing, approximately €26 million, led by Benchmark, with participation from Visionaries Club, the UK Sovereign AI Fund, FR8, Antimatter, Cloudberry VC, Conviction, Embassy Ventures, and SV Angels, along with several angel investors. Founded in 2025 by CEO Nils Cremer and co-founders T6 and Hugo McNally, the company is developing a general-purpose processor architecture that enables thousands of cores to work in parallel.

The new architecture is based on an interaction net computing model, representing programs as interconnected nodes where independent operations can be executed simultaneously, attempting to break away from traditional shared mutable memory and linear instruction sequences. The company is also developing an open-source programming language called Vine, with syntax close to Rust, to facilitate software adaptation to this parallel-first architecture. Tendrils stated that GPUs already handle large-scale numerical computing, but irregular tasks such as AI agents executing code and retrieving documents still rely heavily on CPUs. Jack Altman, General Partner at Benchmark and co-founder of Lattice, will join the board.
