Cua (trycua, YC X25) is open-source MIT-licensed infrastructure for computer-use agents, providing cloud and self-hosted sandboxes across macOS, Windows, Linux, and Android plus an SDK, a virtualization layer (Lume), and a benchmarking/RL-eval suite (Cua-Bench). It positions itself as the 'Docker for computer-use agents,' giving any agent a cloud desktop.

Buyer analysis

Best fit: Teams needing on-demand sandboxed desktop/OS environments to run, evaluate, or generate RL trajectories for computer-use agents.

How we verified this

Confirmed this is the CORRECT entity matching the directory note 'docker for computer-use agents': trycua/cua, YC X25 (Spring 2025), founder Francesco Bonacci (ex-Xbox/Microsoft AI), components Lume/Sandbox/Cua-Bench/Driver, MIT license, ~17.7k GitHub stars, cua.ai. No same-name confusion. Key downgrades: (1) Funding, the $500K figure rests only on aggregators (Tracxn) and LinkedIn with no primary press release; round date/type are inconsistent (June vs July; pre-seed vs seed), so total_raised and last_round language was broadened and notable_investors downgraded confirmed->reported. (2) HQ, YC says San Francisco, Tracxn says Dover, DE; downgraded to reported. (3) Added omitted co-founder Alessandro Puppo. (4) Customers remain self-claimed (OSS 'Trusted by 50,000+ engineers' logo wall, not verified paying customers); Meta retained as frontier-lab tie (FAIR/Llama). (5) SOC2/security confirmed as unknown, no trust/compliance page on cua.ai. (6) Cua-Bench downgraded to reported as a vendor eval product, not a peer-reviewed publication. Open-source, license (MIT), deployment model, and maturity stand as confirmed from primary sources (GitHub + cua.ai/pricing). Tracxn page itself returned 404 on direct fetch, so funding remains aggregator-grade only.
