We bridge the gap between business strategy and technical execution. Our architects design scalable, secure and resilient systems before you spend on building them. Based in Margate, KwaZulu-Natal, we serve organisations in Johannesburg, Cape Town and Durban, across Africa and internationally.
Solutions architecture is the practice of designing a complete technology solution to a specific business problem. A solutions architect defines how applications, data, integrations, security and infrastructure fit together, so the system you build is scalable, secure and affordable to run.
A developer writes code; an architect makes sure you are building the right system in the first place. Without a design, businesses end up with disconnected tools, duplicated data, surprise cloud bills and projects that need rebuilding after launch. We act as your independent technical partner, helping you prevent those costly rebuilds, remove data silos and scale smoothly as the organisation grows.
Whether you are choosing a stack for a start-up, integrating ERP and CRM, moving to the cloud or modernising a legacy estate, the method is the same: understand the business, design the target state, validate the risks and oversee delivery. See our options by organisation size, what you receive, or request a consultation.
Our co-founders have worked on technology modernisation at enterprise scale. Riaan Terblanche and Natasha Jooste were each individually involved in a modernisation programme for Toyota South Africa in Durban, from assessment of the existing systems through to implementing a roadmap to modernise them.

Systems that are secure by design, highly available and deeply integrated, planned before the first line of code is written.
We analyse your current operations, find the bottlenecks and map optimised digital workflows tied to your commercial objectives.
Blueprints that let legacy systems, modern cloud apps and third-party APIs exchange data securely and reliably.
Scalable, highly available designs across Azure, AWS or hybrid setups, built for growth and cost-efficiency.
Zero-trust principles, encryption standards and compliance mapping (POPIA, GDPR) built into the foundation, not bolted on.
Data models, warehousing and reporting design that end data silos and give leadership one trusted view of the business.
Service boundaries, API contracts and event flows for new platforms, or for decoupling a legacy monolith in stages.
Independent comparison of off-the-shelf software and custom development on fit, cost, risk and exit options.
We stay involved after the blueprint, working with your developers or ours so what gets built matches what was designed.
The principles of good design apply at every scale. We match the depth, governance and cost of the engagement to your organisation's maturity and budget.
A solid foundation from day one. We help small businesses choose the right tech stack and avoid costly rebuilds later.
Connect disconnected systems and automate data transfer so teams stop re-typing information between tools.
Move from legacy, monolithic systems to an agile, modern ecosystem in controlled, low-risk phases.
Align complex, multi-site IT estates with business strategy through governance, standardisation and high-availability frameworks.
Every engagement ends with documents you own and can use with us or any supplier. The exact set is confirmed in your proposal.
Context, logical and physical diagrams of the target solution, readable by directors and actionable by engineers.
How every system, API and dataset connects, who owns what, and where data is at risk.
The options considered, the choice made and why, so future teams do not reverse decisions blindly.
Technical controls mapped to POPIA and, where relevant, GDPR. Legal advice stays with your attorney.
A prioritised sequence of work with realistic cost ranges so you know what to fund first.
Technical, delivery and vendor risks with mitigations, plus a clear build, buy or hybrid recommendation.
| Role | Focus | Typical output | When you need them |
|---|---|---|---|
| Software developer | Writing and testing code for specific features | Working software modules | The design is already settled and needs building |
| Solutions architect | Designing how systems, data, security and infrastructure fit together for one business problem | Blueprints, integration maps, roadmaps, decision records | Before a major build, integration, migration or vendor purchase |
| Enterprise architect | Aligning the entire technology estate with organisation-wide strategy and governance | Capability maps, standards, target-state architecture | Large or multi-division organisations managing many systems |
We rely on proven architecture frameworks to document data flows, secure endpoints and map business capabilities to technology, and use the lightest approach that fits your size and risk.
We interview key stakeholders and audit your existing technology landscape to understand current capabilities, constraints and pain points.
We translate business goals into clear functional and non-functional technical requirements: performance, security, availability and budget.
We draft the blueprints: data models, network topologies, API structures and security frameworks.
Proof-of-concepts and feasibility studies test the riskiest assumptions before you commit major investment.
We do not simply hand over a document. We work alongside your developers or our engineering teams so the build matches the blueprint.
Our architecture portfolio is being updated. Contact us to discuss relevant client work.
Our team is based in Margate on the South Coast and works with businesses from Port Shepstone and Durban to Ballito, Richards Bay and Pietermaritzburg. Local presence means face-to-face architecture workshops when you want them.
We provide enterprise architecture consulting, system design and digital transformation planning to organisations in every province, from Johannesburg, Pretoria, Cape Town and Durban to Gqeberha, Bloemfontein, Polokwane and Mbombela. Workshops and reviews run through video calls and shared documents, with site visits where they add value.
We advise African organisations and international companies on system design, cloud and security architecture, planning for variable connectivity, power reliability, currency and local data protection laws. Projects run through secure remote collaboration with milestones agreed up front.
Solutions architecture is the discipline of designing a complete technology solution for a specific business problem. It bridges business requirements and technical implementation, so the final system is scalable, secure and aligned with company goals before any major build begins.
A solutions architect studies how your business works, defines the requirements, then designs how applications, data, integrations, security and infrastructure fit together. They compare options, document decisions and oversee delivery so the result matches the design.
A developer writes code to build specific features. An architect looks at the whole picture: how systems interact, what infrastructure is needed, how data is secured and which technologies will still serve you in five years. Architecture comes before development.
A solutions architect designs the answer to one business problem or project. An enterprise architect governs the whole technology estate across the organisation. Smaller and mid-sized businesses usually need solutions architecture; large multi-division organisations often need both.
Typically before a major build, system integration, cloud migration, ERP or CRM rollout, or software purchase. It is also valuable when systems no longer talk to each other, costs keep rising, or a previous project ran over budget.
Both. We offer standalone architectural consulting for companies with their own development teams, and our in-house engineers can build and deploy what we design. The blueprint belongs to you either way. See our software development and cloud infrastructure services.
Our architects work with industry-standard frameworks and methods including TOGAF, ITIL, AWS Well-Architected, Azure Architecture Center guidance, ArchiMate, BPMN, microservices and event-driven design. We choose the lightest approach that fits your size and risk.
Yes. A build-versus-buy analysis is a core part of our work. We map your requirements, evaluate SaaS and enterprise products on fit, cost, risk and exit options, and tell you honestly whether custom development is justified.
It depends on scope, size and depth. Small focused engagements are quoted as a fixed scope after a short discovery conversation, and larger programmes are estimated in phases before work starts. Request a consultation for a clear written proposal.
A focused small-business design can take one to three weeks. Medium engagements usually take three to eight weeks, large transformations are phased over several months, and enterprise work is scoped in stages with milestones.
Yes. We are based in Margate but work with organisations in all nine provinces, including Gauteng and the Western Cape. Workshops, reviews and reporting run through video calls and shared documents, with site visits where they add value.
Yes, for selected projects. We advise organisations across Africa and in markets such as the United Kingdom, United States, Australia and New Zealand through remote collaboration, taking local connectivity, power reliability and data protection laws into account. Scope and delivery are agreed per project.
We build the technical safeguards into the architecture: access control, encryption, data minimisation, retention and audit trails. POPIA and GDPR are legal frameworks, so we work alongside your attorney or information officer rather than giving legal advice.
Yes. The blueprints, diagrams and recommendations are yours to use with us or any other supplier. We write them in plain language so a director can read them and a technician can act on them.
Engage our architects before you write a single line of code, so your next major digital investment is built correctly from day one.
