[Meticulous](https://meticulous.ai/?utm_source=ashby) is growing revenue exceptionally fast with leading companies adopting the tool at record pace. We’ve brought together a small team of some of the most talented engineers in the world. This has allowed us to build a technology that fully autonomously and exhaustively tests frontend codebases. Such a capability has never existed before, and no other company is even close to building such a capability — it’s built on the back of a range of novel technologies and research (hint: the core itself doesn't use transformers or LLMs, but something more novel). As a result the demand for the product has been immense. In addition to being one of the fastest growing companies, customers like Dropbox, Wiz, Notion are often paying more for Meticulous than any other vendor or software product - and then spontaneously referring us to other companies. We believe that autonomous and exhaustive testing is the missing piece in unlocking the full potential of code generation, and automating the majority of software development. We are a team of ten onsite in London. We believe in building a small but extremely talented team. We are hiring in London and are considering opening up Forward Deployed Engineering roles in San Francisco shortly. If either role sounds interesting please apply to this job posting here. What you may work on: - Build a distributed system to concurrently replay thousands of sessions, such that a developer gets a result in seconds. - Integrate Meticulous into the inner loop of agentic code generation, to produce a coding agent far beyond anything that exists today - by giving it a feedback loop to understand the exhaustive impact of every change it makes and iterate against; while also allowing it to understand the full runtime behaviour of the code it’s editing and space of data and edge cases it may operate over. - Derive algorithms to detect sessions that cover differing code paths and edge cases, and ignore sessions that are too similar. - Work directly with engineering leaders across the world's top technology companies to help them deploy Meticulous to their organisations. What you get from working here: - World-class compensation, exceeding top technology companies and startups. - Work with exceptional colleagues to solve novel and exceedingly difficult problems and change the way the world develops software. Work with some of the very best engineers who were previously at Uber, Google, Dropbox, GitHub, Meta and Palantir, including previously leading 100+ engineer organisations at these companies. - Expand your network - Guillermo Rauch (founder of Vercel), Jason Warner (CTO of GitHub), Calvin French-Owen (founder of Segment), Jared Friedman (YC partner and founder of Scribd), Scott Belsky (CPO of Adobe), Arash Ferdowsi (founder of Dropbox) and many others are all personal investors in Meticulous. We can connect you with anyone in the technology world. ## About Meticulous ## Core Business - **Primary industry**: Software testing & quality assurance, developer tools - **Target customers**: B2B; engineering teams at mid-market and enterprise companies (e.g., Dropbox, Wiz, Notion) - **Mission or purpose**: Radically accelerate the pace of software development by making frontend testing autonomous and exhaustive. ## Products & Services - **[Meticulous Platform]**: A SaaS/AI agent that records user sessions (clickstream + network data) from staging, dev, or production environments. When a developer opens a pull request, Meticulous replays the most relevant sessions against the new frontend, takes screenshots at key interaction points, and detects visual diffs. The test suite evolves automatically — new tests are added as features are introduced, old tests are removed when they become obsolete. Built from the Chromium level up with a deterministic scheduling engine to eliminate flakiness. Tests are parallelized across a compute cluster, returning results in under 120 seconds even for thousands of screens. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metric**: Total funding raised — $4.5M (Seed round led by Coatue, with participation from Soma Capital, Base Case Capital, and Y Combinator) - **Notable Investors/Partners**: Coatue, Soma Capital, Base Case Capital, Y Combinator (S21 batch). Personal angel investors include Guillermo Rauch (Vercel), Jason Warner (former GitHub CTO), Calvin French-Owen (Segment), Jared Friedman (YC partner), Scott Belsky (Adobe CPO), Arash Ferdowsi (Dropbox co-founder). - **Growth Signals**: Profitable with 10x annual recurring revenue growth every 12 months; customers like Dropbox, Wiz, and Notion often pay more for Meticulous than any other vendor and spontaneously refer others; team size of 15 (small, elite). ## Competitive Advantages - **Deterministic replay engine** built at the Chromium level — the only testing tool that completely eliminates flaky tests. - **Exhaustive coverage**: The AI engine curates a suite of visual end-to-end tests that cover every line of code, every user flow, every edge case. - **Zero maintenance**: Tests automatically evolve as the app evolves — no test writing, fixing, or updating required. - **Speed**: Highly parallelized compute cluster allows testing thousands of screens in under two minutes. - **Novel technology** that does not rely on LLMs or transformers, making it difficult for competitors to replicate. ## Strategic Focus - Accelerate the adoption of autonomous testing to unlock the full potential of code generation (e.g., AI-written code) by ensuring regression safety without developer effort. - Continue scaling the distributed replay system to handle increasing session volumes and enterprise demands. - Expand integrations with CI/CD pipelines and developer workflows. ## Why Work Here - **Culture**: Small, extremely talented team of six (currently 15 total) based in London; belief in building a lean, high-impact team. - **Compensation**: World-class — exceeds top technology companies and startups. Salaries range $280K–$400K (San Francisco) or £150K–£300K (London). - **Work on novel distributed systems**: Build a system to concurrently replay thousands of sessions deterministically, derive algorithms for session selection, and push the boundaries of automated testing. - **Network**: Access to a personal network of top technology leaders (investors and advisors) — the company facilitates introductions for commercial reasons. - **Remote/Hybrid**: Primarily onsite in London (office-based), with some roles in San Francisco. - **Perks**: Opportunity to solve exceedingly difficult problems that change how the world develops software; work alongside colleagues who have led large engineering groups at Palantir, Dropbox, etc. ## Sources 1.
