Featured case study · Legal
How Ekons Law modernized its legal operations.
A Nairobi-based litigation firm replaced spreadsheets, email chains, and bespoke filing systems with a unified matter management platform — purpose-built for how their teams actually work.
Challenge
Manual case tracking, fragmented client communication, and KRA-compliant invoicing handled by hand were capping how many matters the firm could carry at one time.
Solution
A bespoke matter-management platform with client portal, automated notifications, M-Pesa and bank payment intake, and KRA-compliant electronic invoicing — deployed in 14 weeks.

SolutionSenior teams that ship production-grade MVPs and scale infrastructure as traction lands.
How we work
A delivery process designed for predictability.
Senior-led discovery, agreed scope, weekly visible progress, and a launch that is the boring part by design.
01
Discovery
Deep dive into operations, constraints, and goals. We map what the business actually needs to ship — not a wishlist.
02
Planning
Architecture, scope, and milestones agreed up front. Clear contracts on what we'll deliver and when.
03
Development
Senior-led builds with weekly visible progress. Code reviewed, tested, and deployed continuously to staging.
04
Testing
Automated and manual QA across critical paths, performance, security, and accessibility — before users touch it.
05
Deployment
Zero-downtime cutovers, monitored rollouts, and rollback paths. The launch is the boring part by design.
06
Ongoing Support
SLAs, observability, and a partner who's still around six months later — most of our work is repeat business.
Technology
Built on production-grade foundations.
Scalable, secure, container-first. We pick boring, reliable technology — then engineer the interesting parts on top.

Brian Otieno
Finance Director · Northwind Logistics
“From discovery to launch in fourteen weeks. The platform is faster than anything we benchmarked against — and we benchmarked everything.”
