The product.

Most businesses outgrow company mobiles long before a PBX makes sense: the numbers belong to employees, calls leave no record, and the customer history walks out when staff do. SemaCall gives the whole business one number instead. It rings a browser, a mobile or an AI agent, by department, language, working hours and routing rules, and goes live in 24 to 48 hours with nothing to buy or install.

Every conversation is recorded, transcribed in the caller's own language and summarised by AI, then turned into tickets, customer records and call-back tasks, so managers see performance, missed calls and what customers are calling about without asking anyone. The call data also connects to AI assistants through MCP, so a manager can simply ask how the support line did last week.

It runs on local numbers in 11 African countries from one workspace, is priced in shillings from Starter to Enterprise, and is built for customer-facing desks: banks and SACCOs, ferries and logistics, insurers, clinics, retail, NGOs and government. Sema also runs customer support for Neurotech's own products, Ghala and Snippe.

What I did

Built across the whole stack.

  • Agent console & call UI

    Browser-based softphone, live queues, call handling, and the dashboards agents work from, no install.

  • Call routing, IVR & telephony

    Smart routing with round-robin / priority / availability rules, IVR menus, working-hours logic, and mobile failover so no call is dropped.

  • Transcription & AI summaries

    The Swahili + English transcription flow and AI-generated post-call summaries, with recordings and emailed transcripts.

  • Compliance plumbing

    Encryption, user-controlled retention, role-based access, and audit logs, the parts a regulated desk actually signs off on.

  • Backend & integration

    APIs, data model, and the unified queue that lets several products and departments share one line.

“Calls from every product land in one queue, routed to the right team, recorded and reported in one place.”
