SellTech

Based in Spring, Texas, SellTech is a small team offering software development and digital marketing services to businesses looking to modernize outdated systems or improve their online presence. The company works across sectors including healthcare, fintech, e-commerce, education, real estate, manufacturing, travel and hospitality, and automotive, positioning itself as a single point of contact for companies that need both technical development and marketing support rather than juggling separate vendors for each function. The service list spans custom software development, including SaaS applications, API development, cross-platform apps, and progressive web apps, alongside enterprise software solutions aimed at addressing integration, scalability, and security issues in legacy systems. Mobile app development covers both native and cross-platform builds. On the web side, the agency handles custom development, e-commerce sites, CMS builds, ongoing maintenance, and performance optimization. Digital marketing services include SEO, PPC advertising, social media marketing, and content strategy, described as aimed at improving search rankings and lowering customer acquisition costs. Branding work covers brand strategy, logo design, visual identity, brand guidelines, and marketing materials, while the UI/UX offering includes user research, wireframing, and prototyping. The site frames these services around solving specific business problems—outdated systems, slow websites, low visibility, and underperforming campaigns—rather than presenting them as standalone packages, and offers a free consultation for prospective clients.
