How he built DIGITEST
According to the founding account in the company’s D&T 1000 user manual, DIGITEST was initially established to provide maintenance and repair services for electronic boards widely used in industry. Within roughly three years, the firm turned to developing a domestic equivalent of the electronic board test and fault detection systems that were then imported at high cost; it first brought out the D&T 500 Fault Locator, followed in 2004 by the upgraded D&T 1000, developed with the support of university faculty members. Over time the company evolved from test equipment into a defense industry firm producing fire control systems, slip rings, joysticks and remote-controlled weapon systems.

Public statements
The most notable of Erseven’s statements reported in the press are:
- Embargoes and localization (February 2020): In his interview with Savunma Sanayi Dergilik, he said the embargoes imposed by foreign countries had provided an “incredible advantage” to the Turkish defense industry and that the company had grown roughly fivefold during crisis periods. In the same conversation he reported producing fire control systems, slip rings and joysticks for the Leopard 2A4, Leopard 1 and M60T tanks, investing about 5 million euros over three years, and holding talks with Airbus and Boeing.
- R&D and registrations (Moment Expo): He stated that the company had developed more than 300 products, held 19 utility model/industrial design registrations, 3 patents and 5 trademark registrations, and had reached a local content rate of roughly 80 percent in the machinery and test equipment used in production.
- Counter-drone systems (November 2024): At SAHA EXPO he said that, against ever-cheaper drones, the company was developing weapon systems to defeat them with lower-cost conventional ammunition; he announced that the ÖNDER-based system was designed and produced entirely in Türkiye and was being prepared for final acceptance tests.
