Our killer differentiator. You won't just build "To-Do" lists. You will architect the exact systems African businesses use daily to survive and scale.

Phase 1: Foundations

M-Pesa Paylink & Receipt Mini-App

Send clients a payment link, trigger M-Pesa STK, and generate instant PDF receipts.

What It Does

A complete end-to-end payment link generator. Business owners can create a unique link, share it with a client, and handle the entire M-Pesa checkout process gracefully. Upon successful payment, a branded PDF receipt is automatically generated and sent to the client.

Real Business Use Case

Freelancers or small service providers who need a professional way to invoice clients and collect mobile money payments instantly without writing complex integration code.

Real Business Use Case

Real estate agencies or car dealerships receiving hundreds of WhatsApp inquiries daily, needing to structure chaos into a manageable sales pipeline.

Multi-Channel Notification Hub

A unified API to send alerts via WhatsApp, SMS, or Email with failover logic.

What It Does

A microservice acting as a central nervous system for communications. If a critical WhatsApp message fails to deliver within 5 minutes, it automatically falls back to an SMS, and subsequently an Email, ensuring guaranteed delivery.

Real Business Use Case

Fintech startups sending OTPs or critical security alerts where delivery failure is not an option, regardless of the user's internet connectivity.

Real Business Use Case

A B2B software founder wanting to build and scale a platform that serves thousands of African businesses securely and efficiently.
