The portfolio
One house. Five ventures. Each one carries the stamp.
Every StampGrid venture solves a problem we've seen up close in Zambia — then earns its place with real users, real revenue, and real compliance.
SG·01 / ProptechIn build
RentStamp
Rentals, without the runaround
A landlord-and-tenant platform for the Zambian rental market: verified listings, digital lease generation, tenant screening, and rent tracking. Money moves directly between landlord and tenant — RentStamp never touches it — so trust is built in, not bolted on.
SG·02 / HospitalityIn build
LodgeStamp
Paperless lodge management
A full management system for lodges, guesthouses, and small hotels: bookings, check-in and check-out, housekeeping, billing, and ZRA-compliant receipts and quotations — eight modules that replace the paper register for good.
SG·03 / Digital healthIn development
PEN-Sync
NCD care at the frontline
A point-of-care platform that operationalises the WHO PEN protocols for non-communicable diseases — guided screening, clinical decision support, and patient follow-up for hypertension, diabetes, and cardiovascular care at primary-care level.
SG·04 / IntelligenceConcept
Nzeru Health
Zambia's public health intelligence
A platform that turns scattered public-health data and evidence into clear, decision-ready intelligence for practitioners, programmes, and policymakers — Zambia's health picture, in focus.
SG·05 / EdTechPrototype
Nzeru Home Tutor
AI-assisted learning, Grades 1–12
An AI-powered tutoring companion covering the ECZ national and Cambridge curricula — lessons generated on demand, tuned to how Zambian learners actually study at home.
