DemenTech Enterprise is a Lagos-based digital solutions company building custom software, SaaS platforms, and telecom infrastructure for African markets.
Founded by Umeh Onyedika Emmanuel and registered with the Corporate Affairs Commission (CAC #7330687) in February 2024, DemenTech operates out of Lagos, with a small, hands-on team.
We specialize in the parts of software most companies outsource or avoid: multi-tenant SaaS architecture, VoIP and PBX systems built on Asterisk and PJSIP, WhatsApp/SMS/email communication infrastructure, and AI integrations that actually ship. Our clients are primarily African businesses, and we design our systems to work in the realities of local carrier routing, Nigerian payment/SMS systems, and WhatsApp first product thinking.
We build and run our own products, which means we're not just consultants; we're operators who run and maintain the systems we design.
