SpendRule Raises $4M Seed Led by Mark Cuban's Radical Investments

SpendRule, a Dallas-based AI contract enforcement platform that makes sure organizations pay what their contracts say, has raised a $4 million seed round led by Mark Cuban's Radical Investments. The company did not disclose a valuation.

Zeal Capital Partners also participated. The round brings SpendRule's total funding to $6 million.

Enforcing Contracts at the Point of Payment

Founded in 2025 by co-CEOs Joseph Akintolayo and Chris Heckler, SpendRule reads contract terms, checks invoices against them, flags overcharges with supporting evidence and drafts credit requests. Each finding shows the clause and calculation behind it, so customers and vendors can work from the same evidence. The platform was first built for hospital purchased services contracts.

"Companies spend all this time negotiating contracts, but what’s the point if nobody checks whether they’re getting what they paid for? That’s the problem SpendRule is solving," said Mark Cuban.

Health Systems Are the First Market

SpendRule says health systems use it today across $2.91 billion in annual purchased services spend and 2,187 business relationships. Customers named in the announcement include OSF HealthCare, Kettering Health, MemorialCare and MUSC Health.

Heckler framed the stakes in clinical terms. He argued that nurses, techs and the people who keep the building running are not the cost problem, and that every dollar lost to a billing mismatch is a dollar that did not go to care.

A Decision Layer for People and AI Agents

The company's ambition reaches beyond hospital invoices. "Every company makes commitments it can’t monitor, enforce or keep current," Akintolayo said.

He said SpendRule turns agreements and policies into deterministic decision systems that check what was billed, chase what is missing and prove the result, and that finance teams can put any contract under continuous enforcement with a single instruction.

SpendRule is also building a layer that tells AI agents what every agreement actually allows. Akintolayo said the goal is to become the infrastructure that makes commercial agreements work across companies, software platforms and AI agents. The SaaS News described the product as a decision layer between contracts and payments for health systems and businesses managing complex vendor agreements.

Why It Matters

Contract compliance is a quiet, expensive problem: negotiated rates mean little if nobody checks invoices against them line by line. SpendRule is betting that AI can do that checking continuously and show its work, which matters when the other side of the dispute is a vendor.

Every overcharge SpendRule flags comes with the clause and calculation behind it, which gives vendors less room to dispute the finding. Starting with hospital purchased services gives the company a market where margins are thin and every recovered dollar has a clear destination. The longer play is broader. As companies hand more purchasing and payment decisions to software agents, something has to tell those agents what a contract actually allows, and SpendRule wants to be that layer.

The customer base is the early proof point. With $2.91 billion in purchased services spend already on the platform, SpendRule has real invoices to test its approach before it widens the target market.
