Tendrils raises $30m seed for parallel-first processors

Benchmark leads a $30m seed round for Tendrils, whose open-source Vine language accompanies a new processor architecture built around interaction nets.

Tendrils has raised $30 million in seed funding led by Benchmark. Visionaries Club, Conviction, Embassy Ventures, Sovereign AI, SV Angel, FR8, Antimatter and Cloudberry VC also participated. Benchmark’s Jack Altman is joining the board.

The Cambridge company wants to make branching computation easier to run in parallel. Its architecture uses interaction nets: programs become graphs whose independent regions can be rewritten concurrently. That approach is aimed at work such as search, simulation, compilers and proof checking, where the next operation can depend on the result of the last.

Tendrils is developing the hardware alongside Vine, its open-source language and toolchain. Developers can already try the software while the processor architecture is being built. The financing supports both parts of that effort.

The company announced the round on November 10, the date also shown on Cloudberry’s investment announcement. Coverage published the following day describes the same seed financing.
