Ellipsis

Ellipsis (ellipsis.dev) is a cloud platform for AI coding agents aimed at engineering teams. Customers deploy fleets of agents for feature development, code review and workflow automation; each agent runs in an isolated sandbox with scoped permissions and hard budget caps. Agents are defined by committing a YAML file to GitHub and can be triggered from GitHub, Linear, Slack and similar tools, or through a REST API or the company's CLI. Organizations receive observability and governance over agent activity, and agent session logs are downloadable so customers retain their own data.

The product began as an AI developer tool that converted technical instructions into working, tested code. Early capabilities included creating multi-file code changes from natural-language requirements such as bug reports or feature requests, reviewing pull requests against best practices and custom rules, answering questions about a codebase during onboarding and bug triage, generating daily or weekly digests of codebase changes, and automating repetitive changes such as library upgrades and refactors. The company described its focus as automating full-stack engineering tasks in the Python and JavaScript/TypeScript ecosystems, with work executed in the cloud rather than on a developer's laptop so multiple tasks can run in parallel. Onboarding options have included a seven-day free trial and, later, a $100 starting credit.

Founding story

Founder and CEO Hunter Brooks previously built a code-generation product that dynamically created programming challenges for technical interviews, worked as a machine learning engineer at AWS and Amazon Ads, held engineering roles at Brigit and Capital One, and published in astrophysics before teaching himself to code. Co-launcher Nick was founding engineer at Grit, where he took an AI developer tool for codebase migrations from zero to one, researched LLM interpretability at Redwood Research, managed teams at Hyperscience and worked on trading algorithms at Bridgewater Associates. The pair launched Ellipsis with the stated mission of building an AI software engineer.

Business model

Ellipsis sells its cloud coding-agent platform to engineering organizations, with self-serve onboarding via a free trial and a $100 starting credit, and offers demos for teams; usage is bounded by per-agent budget caps.

Traction

Cited customers include PromptLayer and Warp, with review examples published from open-source repositories. The team size was listed as two.

Latest developments

The company's positioning has expanded from automated pull-request review and bug fixing to a cloud platform for deploying fleets of coding agents with sandboxing, scoped permissions, budget caps and full observability, offered with a $100 starting credit.
