The math is simple, and for a large real estate operator, it is maddening. A portfolio might have thousands of vendor contracts, each with its own pricing schedule, renewal clauses, and insurance requirements. The monthly invoices pour in, a river of PDFs and scanned paper. Somewhere in the flow, money leaks. A rate is billed incorrectly. A service is charged but not performed. A renewal auto-triggers at a higher rate, unnoticed until it hits the net operating income statement. Finding those discrepancies has traditionally been a manual, forensic accounting task, a cost of doing business measured in lost margin.
MARC, a startup founded in Dublin in 2024 and now based in New York, is betting that an AI-native layer can plug those leaks. Its platform connects to an operator’s existing systems,email, SharePoint, property management software,to find agreements, extract their key terms, and then automatically compare them against incoming invoices [Tech.eu, February 2026]. The goal is to flag discrepancies and potential overbilling before costs affect the bottom line, turning a reactive audit function into a continuous control layer [Commercial Observer, October 2026].
A wedge in multifamily operating expenses
The initial target is the institutional multifamily sector, where operating expenses (OpEx) are a primary lever for asset value. MARC positions itself not as another property management system, but as an intelligence layer that sits on top of the messy reality of how contracts and bills are actually managed. The platform’s “AI contract agents” are designed to handle the repetitive work of matching line items, tracking renewal dates, and surfacing consolidation opportunities across a portfolio’s vendor base.
By the time of its $5 million seed round in October 2026, the company reported it was already managing more than $100 million in annual vendor spend for clients across 30 U.S. states and Canada [sproutsignals.com, October 2026]. That figure, while provided by the company, suggests a wedge into a critical and data-rich workflow. The bet is that saving a percentage point or two on vendor spend is a compelling enough ROI to justify the software’s cost, especially for operators managing billions in assets.
Founder trajectory and transatlantic traction
The company is the project of solo founder Aaron Devitt, who was 24 when the seed round was announced [Tech.eu, February 2026]. His path to New York real estate tech was not linear. He deferred his studies at Technological University Dublin to build the business, first launching a property management product for the U.K. and Irish markets. That earlier product reportedly grew to more than 40,000 monthly logins and was adopted by some of Ireland’s largest property managers, providing an initial revenue stream and proof of concept [Business Plus, October 2026][Irish Tech News, October 2026].
This early traction helped attract initial capital. A $1 million pre-seed round in February 2026 was backed by two dozen angel investors, including Jack Pierse of Wayflyer and Tom Kennedy of Hostelworld [Tech.eu, February 2026][Silicon Republic, October 2026]. The subsequent $5 million seed round eight months later was led by New York-based venture firms Work-Bench and MXV Capital, signaling a deliberate pivot to the U.S. institutional market [Commercial Observer, October 2026].

The competitive landscape and execution risks
MARC enters a crowded proptech arena, but its specific focus on spend intelligence and contract compliance carves out a niche. Its competitors range from broad property management platforms like MRI Software and AppFolio to more specialized vendors in areas like procurement or facilities management. The differentiation rests on the AI-driven, cross-system analysis of unstructured contract and invoice data,a technical challenge that, if solved reliably, could create a sticky product.
The risks, however, are substantial and familiar for an AI-centric SaaS play.
- Data integration depth. The value proposition hinges on smooth connections to a myriad of legacy systems, from on-premise SharePoint servers to various property management APIs. Any friction in data ingestion directly limits the accuracy and comprehensiveness of the leakage analysis.
- Accuracy and false positives. An AI flagging a potential overcharge is only as good as its precision. A high rate of false alarms would erust operator trust and burden teams with verification work, negating the promised efficiency gains.
- Sales motion scale. Selling to institutional real estate owners is a relationship-driven, high-touch process. Scaling a direct sales team in the competitive U.S. market will be a capital-intensive test of the seed funding.
The company’s answer to these risks appears to be a focus on narrow, repeatable workflows within multifamily and a founder who has already navigated a product launch to thousands of users. The reported claim of managing nine-figure annual spend indicates some early enterprise validation, though named customer references are absent from public reports.
The unit economics of leakage prevention
The ultimate test for MARC will be in the arithmetic of its value capture. Take the company’s own reported figure of over $100 million in managed annual spend [sproutsignals.com, October 2026]. If its software can reliably identify and help recover even 1% of that sum in leakage,a conservative estimate in an industry where vendor overpayment is common,that’s $1 million in annual savings for its current client base. The software’s price needs to sit comfortably beneath that created value. For a portfolio with $500 million in annual vendor spend, a 1% recovery translates to $5 million; the cost of the platform becomes a rounding error on the savings.
To win its category, MARC must outperform the incumbent method, which isn't another software company, but the status quo: a combination of manual review, annual audits, and resigned acceptance of leakage as a cost of business. Its AI agents don't need to be perfect. They just need to be consistently better, and cheaper, than the alternative of human accountants sifting through PDFs. The seed funding from Work-Bench and MXV is a bet that they can be.
