Software development - Harare, Zimbabwe
We build the software African businesses actually use.
We're the team behind Propertyzone. We build custom platforms, internal tools, and SaaS products for businesses operating in real Zimbabwean conditions: USD pricing, WhatsApp-first customers, ZESA-tolerant architecture, Paynow on the rails.
The reality
Most software sold into Zimbabwe doesn't fit Zimbabwe.
Foreign SaaS breaks on local payment rails, assumes 24/7 power, and prices in currencies your customers don't hold. Local builds often ship without a roadmap and stall after launch, leaving you with code nobody can extend.
We build for the conditions that actually exist on the ground: USD pricing, WhatsApp as a primary channel, offline-tolerant flows, and operators who need to run the system manually before it ever sees automation.
Services
What we build
Custom platforms
End-to-end web platforms and internal tools. Built on Next.js, TypeScript, and the same stack that runs Propertyzone in production.
Integrations and automation
WhatsApp, Paynow, EcoCash, Google Workspace, your CRM, your sheets. We wire the workflows already running your business so they stop running on copy-paste.
Technical strategy
Stuck between vendor pitches and engineering quotes? We deliver architecture, a roadmap, and a build proposal: flat fee, two-week turnaround.
How we work
Four stages. No retainers. No scope theatre.
Discovery (paid, 1 week)
A scoping call, a written brief, a 1-page architecture diagram, and a fixed-price build proposal. You leave week one with a yes/no decision, not a follow-up next steps deck.
Pilot (2 weeks, fixed price)
We build the riskiest slice first. If the pilot doesn't validate the approach, we stop. You keep everything we built, no cancellation fee.
Build (4-8 weeks, fixed price)
Weekly demo. Weekly progress note. Fixed scope, fixed price, fixed timeline. Scope changes get re-quoted, not absorbed.
Handover and operate
We train your team to run the system manually first. We automate after we've seen the workflow run for real, with real data, in your hands.
Why Sparkline
We built Propertyzone. Now we build for you.
We don't sell retainers. We sell outcomes: a defined deliverable for a fixed price, on a fixed timeline. That's the same commercial model we use for Propertyzone, and it's the only one we offer clients.
Outcome-tied pricing
Flat fee per deliverable. No hourly bills, no scope creep, no discovery extension invoices.
Manual-first design
We run the workflow manually with you before we automate it. Saves you money. Stops you automating the wrong thing.
Zimbabwe-native stack
USD billing, WhatsApp routing, Paynow / EcoCash integration, ZESA-tolerant architecture. Each one shipped in production.
Founder-led delivery
Code is written by the founders. No offshoring. No agency middlemen. You talk to the people building it.
