Top Artificial Intelligence Startups in California, US

Custom small models trained for specialized use cases powered by scalable infrastructure

Tasklet is building the AI platform companies use to run their business on agents. Our customers describe an outcome in plain English, and Tasklet gets the work done—across SaaS tools, APIs, browsers, files, spreadsheets, and internal systems. Agents can respond immediately or run business processes in the cloud 24×7 on a schedule or in response to events. Every Tasklet agent gets its own cloud computers, filesystem, database, and browser. Tasklet agents are built to do real work at real companies where many people are involved in each function. Teams share agents, knowledge, connections, and conversations, while administrators control access, behavior, and spend. Tasklet users can choose among models and delegate work to faster, cheaper ones—giving companies one flexible platform instead of a growing pile of disconnected AI seats. We compete with ChatGPT Work and Claude Cowork. OpenAI and Anthropic have their own models, massive funding, and existing distribution. We have a small, exceptional team, the freedom to use the best AI tech from any vendor, and a laser focus on the problems of real-world businesses where making agents simple, trustworthy, and easy to control matters just as much as making them intelligent. The labs will define what intelligence can do, but Tasklet will define how businesses put that intelligence to work.
