DESSS is a Houston-based custom application development company with over 20+ years of operating history, headquartered at 2825 Wilcrest Dr, Houston, TX 77042. We have delivered 350+ software projects for mid-size and enterprise businesses, with concentrated experience across oil and gas, healthcare, logistics, construction, and professional services — the industry sectors most represented in Houston's local economy.
Unlike agencies that focus primarily on consumer mobile app stores or templated marketing websites, DESSS builds internal systems, customer portals, and enterprise platforms tied directly to a company's daily operations: approval flows, compliance reporting, integrations with existing ERP/CRM systems, and dashboards that leadership teams use to make decisions. Our technology stack spans React, Angular, Node.js, .NET, Python, and Java, with integration experience across Zoho CRM, Salesforce, SAP, and Oracle ERP.
Over two decades, DESSS has maintained a 92% client retention rate — meaning the large majority of our active engagements are long-term relationships with businesses for which we built an initial system years earlier, and have continued supporting and expanding since.
