Launching the AI platform that redefined accounting — from stealth to $6.3M and acquisition

Materia AI was founded in 2022 by Kevin Merlini and Lucas Adams. Both had previously worked together at Facebook, where they led product and engineering teams for news integrity and AI systems. Merlini started his career as an auditor at KPMG but left after four months, frustrated by the repetitive, low-value tasks that consume most of an auditor’s day. That experience became the seed for Materia.

The co-founders incubated the idea at the Allen Institute for AI in late 2022, months before ChatGPT launched publicly. Their thesis was simple: the accounting profession was critically underserved by technology, and recent advances in generative AI made it possible for the first time to automate workflows that relied on unstructured data and qualitative judgment, tasks that were previously impossible to touch with traditional automation.

The market reality backed them up. The U.S. was facing a worsening shortage of accounting professionals, 75% of CPAs set to retire within 15 years, new CPA candidates down 33%, and firms across the country struggling to retain talent in a profession weighed down by manual drudgery. By mid-2024, Materia emerged from stealth with $6.3 million in seed funding led by Spark Capital, with participation from Haystack Ventures, Thomson Reuters Ventures, Exponent Founders Capital, and the Allen Institute for AI. The platform was already live with five clients, including firms in the U.S. top 100.

The challenge was to enhance Materia’s online presence and user engagement through a complete website overhaul. But the stakes went far beyond a redesign.

Materia was entering a market flooded with generic AI startups, all making similar promises. The accounting audience, firm partners, CTOs, and compliance leads, is inherently conservative and risk-averse. They don’t adopt new technology based on sleek marketing; they need to see SOC 2 compliance, authoritative content sources, and proven security before they’ll even book a demo. The product itself was technically complex: an AI assistant, a document analysis workspace, a centralized knowledge hub, and automated workflow integrations, four distinct capabilities that needed to be communicated clearly to non-technical buyers.

The website wasn’t just a brand exercise. It was Materia’s primary sales tool, the front door for every enterprise deal. It needed to establish instant credibility, explain the product without overwhelming, and convert high-intent visitors into qualified demo requests. All of this while the company was still in stealth, competing for attention against well-funded competitors with larger teams and louder marketing.
