22-year-old college dropout backed by 23 heavyweight angels builds AI-native proptech

MARC, a Dublin-based AI company, is changing how large real estate portfolios manage contract and expense data. Backed by investors including Jack Pierse (Wayflyer), Susan Spence (SoftCo), Tom Kennedy (Hostelworld), and more, founder Aaron Devitt built MARC to reinvent how critical asset management data is managed at scale. Since launching in 2024, MARC has scaled from 40-unit Irish property managers to 25,000-unit US-based owners.

After seeing firsthand how poor property management practices affected renters and asset managers, then 22-year-old Devitt deferred from college to build proptech startup, Marc to serve as the contract-to-invoice truth layer for the property industry. MARC’s AI agents turn buried vendor contracts into structured, live operational data, cutting work that typically takes 2-3 months down to a matter of seconds.

Large property portfolios can involve thousands of vendor contracts covering services, licenses, and certifications. Critical details such as renewal dates, termination rights, escalation clauses, and fee structures are often scattered across inboxes, shared drives, and legacy systems, making budgeting, routine audits, asset sales and invoice comparison reviews slow and error-prone.

MARC builds AI Contract Agents that locate, uncover, read, and structure every contract across fragmented organisations.

MARC addresses this by deploying AI agents that plug directly into existing document stores, including email inboxes and SharePoint. The system automatically locates contracts, extracts key terms, and organises them into a live source of truth that teams can query instantly, enabling asset management teams to operate 200 times faster than humans.

MARC also compares historically buried contract terms against monthly invoices, helping institutional operators identify discrepancies and over billings before they impact net operating income (NOI).

Since launching in 2024, MARC has grown from serving local Irish property managers to working with institutional owners managing 5,000–35,000 units across the U.S. and Canada. Its customers now represent more than $80 billion in assets under management.

After securing some of Ireland’s largest property managers as customers, including Sherry Fitzgerald Lettings and DNG Lettings, in 2025, the MARC team began to serve institutional real estate owners across North America. The company now works with multiple operators managing between 5,000 and 30,000 residential units across more than 20 U.S. states. Today, MARC’s customers represent a combined assets-under-management (AUM) figure of over $75 billion.

“When you manage thousands of units, contract data directly affects asset values, but most teams can’t access that data quickly or reliably,” said Aaron Devitt, Founder and CEO of MARC. “On top of this, the relationship between the Accounts Payable (AP) systems and Contract Management Systems (CMS) have been historically disconnected, causing marginal and continuous over billing at scale. To the tune of many millions of dollars for larger residential portfolios.”

“This is why we built MARC, the connective layer between the CMS and the AP systems, ensuring every portfolio contract is accurate, up-to-date and being billed for accordingly, without thousands of human hours required to find, vet, and verify thousands of contracts.”

MARC has raised a $1 million pre-seed round from 23 angel investors, with no venture capital participation. Backers include Jack Pierse (Wayflyer), Tom Kennedy (Hostelworld), Susan Spence (SoftCo), Eoghan Quigley (Dublin Chamber of Commerce), and James McGann (Unmind), alongside multiple institutional real estate investors and U.S.-based multifamily executives. The funding is being deployed to advance the product and drive expansion into the North American market.

“Backing founders like Aaron is how we continue to build Ireland’s next generation of global technology companies,” said Jack Pierse, co-founder of Wayflyer. “MARC is tackling a deeply entrenched problem in real estate with an AI-native approach, and the early traction in the U.S. speaks for itself. This is the kind of ambition and execution we should be supporting more of from Irish startups expanding internationally.”

MARC is headquartered in Dublin, Ireland, and serves institutional real estate owners across North America and Canada.

Following a period of exceptional momentum, with revenue increasing more than 10× in the past four weeks and the team tripling in size, MARC is fully focused on execution. The company is prioritising customer delivery and product velocity in an otherwise antiquated industry, while continuing to hire across engineering to support rapid scale.
