Akuity.io was founded by Argo co-creators Hong Wang and Jesse Suen. Hong and Jesse were founding engineers at Applatix, which open-sourced the Argo project in 2017. After Applatix's acquisition by Intuit in 2018, Argo exploded in growth with the additions of Argo CD, Rollouts, and Events and was accepted as a CNCF incubating project. Akuity was formed to help companies modernize their tooling on Kubernetes, leveraging Argo, the leading open-source suite of Kubernetes-native application delivery software. Akuity is a staunch proponent of open-source software. We believe it to be the best method of impactful and lasting software development. We also recognize that at a certain stage in a project’s maturity, OSS benefits from commercial backing to help take it to the next level. We started Akuity to advocate for the Argo project, share our knowledge and deep expertise of its capabilities, and become a trusted voice for its users.

Firecrawl is the easiest way to turn the web into data AI agents can use. One API call converts any URL into clean, LLM-ready markdown or structured data - the boring-hard problem everyone building with LLMs eventually hits, solved. We hit 8 figures in ARR in year one and more than doubled it in year two. We have 150k+ GitHub stars, and developers, agents, and category-defining AI companies build on us every day. Growth like this is rare, and we're just getting started. We're a small team punching far above our weight. Everyone here owns a real piece of the product and company, end to end, and runs it themselves - no hiding behind process or headcount. This is a place for people who want to work at the frontier: an AI company building the infrastructure other AI companies run on, not one bolting AI onto an existing product. We move fast, go deep, and are building the tools superintelligence will rely on to gather data from the web.

IR Labs is an applied AI studio and a venture of Integrated Research Limited. We build products where AI meets hard engineering problems, and we run them as real businesses. Our first product, Agentic SQA, is live. It investigates pull requests in C codebases and reports likely defects with evidence: the suspected failure mode, the exact scope and the next step. When nothing clears the bar, it stays silent. It runs on real repositories today, it is generally available and customers pay for it. It was built for the hard layer. Kernel modules, device drivers, firmware, embedded targets and the C libraries everything else stands on. The code where a bad merge costs weeks, not minutes. AI solved writing code. Trusting it is the harder problem, and verification is the scarce layer. That is the company. We are a small senior team, US based and fully remote, working in cross-functional squads across AI and ML, data infrastructure, systems, compiler engineering and product. We look for deep technical ability, strong systems judgment and a bias toward proving ideas in working systems. We are comfortable being wrong fast and changing direction when the data says to. Before you talk to us, use the product. Form your own view. Every conversation we have starts with what you saw.
