Quillon, the AI startup formerly known as Acclara AI, has raised $1.5 million in pre-seed funding to accelerate the development of its audit-grade artificial intelligence platform for technical accounting and financial reporting. The financing will support product development, engineering expansion, and the company’s go-to-market efforts as it seeks to broaden adoption among public companies, accounting firms, and financial consultants.

The pre-seed round was led by 42CAP, a Munich-based venture capital firm known for investing in early-stage B2B software companies. The financing also included participation from angel investors affiliated with NVIDIA and Roblox. The backing reflects investor confidence in Quillon’s approach to applying artificial intelligence to one of the most complex areas of enterprise finance.

Founded in 2023 by Nikolay Dakov, Ivaylo Stefanov, and Atanas Dobrev, Quillon operates between Sofia, Bulgaria, and San Francisco. The company focuses on helping accountants, auditors, and finance professionals interpret complex accounting standards and prepare documentation that can withstand regulatory and audit scrutiny. Rather than offering a general-purpose AI assistant, Quillon has developed a specialized workspace built specifically for technical accounting and financial reporting.

The company’s platform combines a proprietary knowledge graph of accounting concepts with direct integration to the U.S. Securities and Exchange Commission’s EDGAR database. This allows users to research accounting guidance, benchmark peer disclosures, analyze contracts, and generate audit-ready technical accounting memoranda. A defining feature of the platform is that every AI-generated conclusion is traceable back to its original source material, allowing professionals to verify recommendations and maintain confidence in regulatory compliance.

Quillon says more than 500 accountants across U.S. public companies, audit firms, and consulting organizations already use the platform. According to the company, customers save more than 50 hours each month by automating research and drafting workflows while maintaining complete citation trails for every recommendation produced by the AI system. This emphasis on transparency distinguishes the platform from many general AI applications that cannot consistently provide verifiable references.

Technical accounting has traditionally required professionals to spend substantial amounts of time researching accounting standards, reviewing prior filings, and documenting their conclusions in formal memoranda. These documents often become critical during financial statement audits and regulatory reviews. Quillon’s platform is designed to streamline these workflows while preserving the documentation standards required by auditors and regulators.

The newly raised capital will be used to expand Quillon’s engineering organization and continue developing its AI-powered drafting workspace. The company is also investing in broader go-to-market initiatives as it expands its presence among enterprise customers in the United States. Leadership has indicated that future product development will extend beyond technical accounting memoranda into additional financial reporting workflows, allowing finance teams to automate a wider range of compliance-related activities.

Investor support from 42CAP adds an experienced enterprise software investor to Quillon’s cap table. The venture capital firm has previously backed companies in artificial intelligence, enterprise infrastructure, and data management, supporting founders building globally scalable software businesses. The participation of angel investors with experience at NVIDIA and Roblox also brings additional technical expertise as the company continues refining its AI platform.

Quillon’s financing comes amid increasing enterprise demand for specialized artificial intelligence applications capable of addressing industry-specific workflows. While general AI assistants have become widely available, highly regulated industries such as accounting require systems that provide transparent reasoning, accurate citations, and outputs that can withstand professional review. Quillon has built its platform around these requirements by ensuring every response can be traced directly to authoritative accounting guidance and regulatory sources.

The company believes this approach positions it to serve organizations handling increasingly complex accounting issues, including mergers and acquisitions, revenue recognition, lease accounting, debt restructuring, and other areas requiring detailed technical analysis. By reducing the time professionals spend on research and document preparation, Quillon aims to improve efficiency without compromising accuracy or audit readiness.

With its $1.5 million pre-seed financing led by 42CAP and supported by angel investors affiliated with NVIDIA and Roblox, Quillon is advancing its mission to modernize technical accounting through artificial intelligence. As adoption of AI continues to grow within enterprise finance, the company is positioning its audit-grade platform as a trusted tool for professionals who require both automation and verifiable accuracy.
