Problem

Coasty addresses the automation gap in back-office work that still runs through legacy desktop software, payer portals, EHRs, remote desktops, spreadsheets, PDFs, and other systems without usable APIs. Traditional RPA depends on brittle selectors, XPath, and object IDs, so a small interface change can halt a bot and trigger costly inspection, redevelopment, testing, and redeployment. Coasty cites industry estimates that as much as 40% of RPA maintenance time can be consumed by UI changes, creating a rebuild-on-change treadmill across large bot estates. The economic pain is compounded when manual SOP execution creates bottlenecks or when a technically successful but incorrect action causes downstream operational, regulatory, or financial damage.

The clearest initial use case is healthcare operations: automating workflows that span payer portals, EHRs, PDFs, spreadsheets, and remote desktops, such as opening a patient record in a billing portal, entering authorization data, checking member and procedure codes, and returning a confirmation number. These workflows are high-value because they are repetitive but exception-heavy, difficult to integrate through APIs, and costly when a wrong action passes silently. Coasty is initially targeting this segment because the combination of messy interfaces and high-consequence decisions makes reliability more valuable than simple first-pass automation.

Product / Service

Coasty provides a computer-use agent and developer API that operates real desktops, browsers, and terminals through visual interaction rather than relying on application-specific selectors. Developers can send screenshots and natural-language instructions to endpoints such as /v1/predict, or hand Coasty an outcome and let it plan, provision a machine, execute the task, and manage the loop. The platform includes stateful sessions, managed Linux or Windows virtual machines, versioned workflows with conditions, loops, retries, parallel steps, schedules, triggers, webhooks, and human-approval gates. Runs take place in isolated virtual machines, with event streaming and replay or audit information for oversight.

The delivery model is infrastructure-as-a-service: plain HTTPS and JSON, no SDK required, with optional bring-your-own-model keys and metered usage rather than a mandatory subscription. Pricing is usage-based, including a published $0.05 per agent step for task runs and $0.05 for a base /v1/predict call, with machine runtime charged separately. The intended benefit is a more resilient automation layer that can see and adapt to UI changes, recover from mid-task errors, verify important invariants, and escalate uncertain or high-consequence actions to a person instead of failing quietly.

Market

Coasty competes in computer-use AI infrastructure, agentic process automation, developer tools, and the broader RPA and workflow-automation market. Its direct enterprise alternatives include established RPA platforms such as UiPath, Blue Prism, Power Automate, Pega, and Automation Anywhere; Coasty itself frames its product as an option for the changing interfaces and exception-heavy workflows where conventional RPA is weakest. Adjacent competitors include browser-automation infrastructure such as Browserbase and model-level computer-use APIs from providers such as OpenAI and Anthropic. Coasty’s differentiation is its end-to-end combination of visual action, managed computers, workflow orchestration, recovery, verification, and human handoffs rather than a model endpoint alone.

The company appears to be early but not pre-revenue. Y Combinator lists Coasty as an active Summer 2026 company founded by Prateek Jannu and Nitish Kovuru with a two-person team. In its YC materials, Coasty reports paying customers on four continents, a few thousand active users, and 24× growth since Claude Cowork launched; those traction figures are company-reported. Its technical traction includes an independently verified 82.81% OSWorld score and an 85.60% internal result, while its commercial proof point remains early-stage customer adoption rather than disclosed revenue, contracts, or funding figures.
