Dura Software operates as a specialized holding company that acquires, owns, and operates hyper-niche B2B software businesses. Founded in San Antonio, Texas, in 2017 by Paul Salisbury and Michael Girdley, the firm was created to provide a long-term home for software companies, distinguishing itself from typical private equity firms by its intention to never sell the businesses it acquires. This "buy-and-hold" strategy appeals to founders who are concerned about the legacy of their life's work and the future for their employees and customers.
The company's founding was a meeting of complementary expertise. Michael Girdley, an experienced startup investor in the San Antonio tech scene, identified a market gap where founders of smaller, niche software companies had no suitable buyers. Simultaneously, Paul Salisbury was seeking a new entrepreneurial venture after a successful executive career at companies like Rackspace, Dell, and Ernst & Young. A mutual connection introduced them, and they mapped out the framework for Dura Software, combining Girdley's investment acumen with Salisbury's operational expertise.
Dura's business model centers on acquiring 100% of established, mission-critical software products with stable financials and loyal customers. It targets companies in the "neutral zone," typically valued between $1.5 million and $5 million, which are often too small for private equity and too large for individual buyers. Upon acquisition, Dura relocates the headquarters to San Antonio, deploys its own management teams, and applies its operational playbook to improve processes like sales and marketing, fostering long-term, profitable growth. Initially focused on distressed companies, the firm has since shifted its strategy to acquire healthier businesses to optimize them more quickly. Revenue is generated from the operations of its portfolio companies, which serve over 3,500 customers globally across various industries, including maritime, healthcare, and contact centers.
Since its first acquisition of Moki Mobility in 2018, Dura has steadily expanded its portfolio, acquiring over 15 companies, including Nordic IT, 6Connex, and DB Technology. The firm's growth has been supported by significant funding, including a $50 million investment from Peterson Private Equity, enabling an accelerated acquisition pace. By consolidating and optimizing these specialized software businesses, Dura aims to build a diversified and durable stream of cash flows.
