“Can a project-based ERP vendor become the intelligent operating platform for every high-stakes, compliance-heavy industry without ever having to become a fintech?”
Founded 1983 as Deltek Systems, a specialist ERP vendor for government contractors and project-based professional services firms. IPO'd in 1997, went private in 2002 after the dot-com crash. Thoma Bravo took it private again in 2012 at $1.1B, then flipped it to Roper Technologies in 2016 at $2.8B — where it remains as an operating subsidiary. Today Deltek is the category-defining vertical ERP for GovCon, aerospace & defense, architecture & engineering, construction, and consulting, with 30,000 customers across products like Costpoint, Vantagepoint, Maconomy, ComputerEase, and Ajera. Embedded finance is deliberately thin: Deltek acts as the system of record and partners with third parties (Corpay for AP disbursement, Plaid for bank feeds, Ramp for spend) rather than issuing money or lending itself.
Deltek connects to bank accounts through Plaid.
Deltek uses Corpay for FX and cross-border payouts.
Deltek integrates with QuickBooks and Xero.
The Embedded Finance Index 2026 maps 4 layers in Deltek's stack: Open banking (Plaid); FX & payouts (Corpay); Accounting (QuickBooks and Xero); Spend / AP (Ramp and Corpay).
Deltek was founded by Donald deLaski and Kenneth E. deLaski and is founded in 1983, headquartered in Herndon, Virginia, United States.
Deltek's acquisitions include Replicon (2023), TIP Technologies, ArchiSnapper and ComputerEase.
