A technically ambitious play in the growing computer‑use agent market with clear vertical pain points, but it faces stiff competition, high building costs, and enterprise adoption hurdles.
Founder verdict
MAYBE
A technically daring vision with immense potential, but execution risk and competition make it a high‑stakes play best attacked via a narrow vertical wedge.
What is Coasty?
Coasty builds computer‑use AI agents that read screens like a human's eye and perform tasks by clicking, typing, and reasoning—without brittle APIs, selectors, or code. Targeting enterprises and vertical SaaS, it offers a multimodal API, a self‑hosted agent, and a data‑generation service for long‑horizon trajectories. Its self‑healing loop and ability to handle unstructured data let it automate high‑volume, UI‑heavy workflows across insurance, accounting, freight, healthcare, and IT ops. Backed by Y Combinator, it is currently in the early‑stage, selling through demos and API keys, with pricing undisclosed.
