The Sahrène Standard
Fixed milestones, a live staging environment from the first sprint, and a warranty after launch.
Database schemas, system diagrams, UX wireframes, fixed milestones.
Bi-weekly feature releases deployed to live staging environments for continuous client review.
End-to-end testing, POPIA compliance checks, penetration hardening.
Zero-downtime launch, complete IP handover, documentation, and dedicated post-launch support.
Technology stack
We choose the stack for your constraints: performance, the skills of your team, hosting and the long-term cost of ownership.
Engagement models
Choose the model that fits where your product is today. Every model includes full ownership of the source code.
For MVPs, rapid prototypes, and scoped feature blocks. Predictable timeline and budget.
Best for MVPs and prototypes
Monthly senior capacity allocation for continuous product scaling.
Best for scaling products
Rapid independent audit of existing codebases, performance bottlenecks, and security flaws.
Best for existing codebases
Questions
Straight answers on cost, ownership, payments, progress and what happens after launch.
It depends on scope, integrations and the level of polish your product needs. Most projects start with a fixed-scope sprint priced against agreed milestones, so you know the budget before the build begins. Our project form lists budget brackets from R20,000 to R80,000 and above. Choose the closest one and we will recommend an approach that fits it, or tell you plainly if it does not.
You do, from day one. You own 100% of the source code, designs and documentation we create for you, and your agreement with us assigns the intellectual property to you. At handover you receive full access to the code, infrastructure and documentation, with no licence fees and no lock-in.
Yes. We integrate with Stitch, Ozow, PayFast and Peach Payments, including card and instant EFT flows, with reconciliation designed so that no transaction is lost or recorded twice.
You get a private Slack or Microsoft Teams channel with the team, sprint tracking in Jira or Linear, and a video demo every week. From the first sprint, every feature is deployed to a live staging environment, so you review working software rather than slides.
Every launch includes a 60-day warranty: if something we built does not work as agreed, we fix it at no cost. You also receive complete documentation and a full handover. After that, you can keep a dedicated engineering pod for ongoing development, or agree a support plan with defined response times.
