Million
Remember the first time you hit and your code actually worked? Something that didn't exist before, now alive on your screen. Today, coding agents can do that, orders of magnitude faster. But their verification is shallow at best. The faster agents generate code, the wider the gap grows. Nothing verifies software at the speed agents ship code. We believe verification unlocks long-horizon coding agents: agents that run for days and prove their work as they go.

sourceMillion is classified as AI agents from source descriptions and fund-directory context. Similar companies below are ranked from offline product facets and meaningful description overlap; category and source affiliation can only strengthen an existing product match. For lookup-created rows, the profile starts as pending enrichment until deeper source collection runs.
Local clusters rerank extracted product concepts and description terms. The generated graph remains the fallback for sparse descriptions: offline reciprocal product-similarity graph: extracted concepts + description terms + bounded category/affiliation boosts. Minimum fallback score: 0; max competitors: 6.

Canary
match 73AI coding tools have made developers 100x faster but customer-facing incidents are up 43% YoY, QA hasn't kept up. Canary is the first AI QA engineer that understands your codebase. Instead of relying on flaky DOM scraping or screenshot analysis, Canary reads your source code directly to understand developer intent and catch broken user flows before they hit production. Engineering teams go from weeks of manual testing to 90%+ coverage in days. Built by a team that built coding agents at Windsurf

Amiato
match 62Amiato's real-time integration service moves your data to where it's most valuable to you. Today's flexible databases like MongoDB and CouchBase let agile businesses accelerate and scale their operations, but analyzing their data has been elusive. Amiato unlocks the value of that unstructured data by bridging the gap to familiar tools in the rich structured world of BI, all with zero setup work. Run reports, do interactive ad-hoc analysis, and combine disparate silos. Our Schema-lift (TM) techno

Haystack
match 57Haystack helps engineering teams manage the growing volume of AI-generated pull requests. Coding agents make it much easier to produce code, but they also create a new problem: teams now have more changes to review, many of them larger, more frequent, and harder to trust at a glance. Haystack sits on top of GitHub and acts as the control layer for AI-generated code changes. For every pull request, it looks at the codebase, the diff, the agent trace, the author’s intent, and any verification evid

Definite
match 49Definite builds AI agents that generate the reports banks and financial institutions file with their regulators. Before any number lands in a filing, our verification engine checks it independently. Every line gets recomputed from ledger records and checked against a versioned rulebook, and wrong outputs go back to the agent with the reason, like compiler errors. They don't ship. We met our first year studying computer science at the University of Waterloo, and interned at Meta, Optiver, and Bit

Crouton
match 46Crouton is the living map of your organization. It’s for founders and operators at growing companies who need to understand how people, teams, roles, and ownership actually fit together. Today they piece this together from org charts, Notion docs, spreadsheets, Slack, and memory and then redo it every time something changes.
