2026 · in production
What “custom software” means in 2026 is not what it meant in 2020. The buildable surface area expanded — and most agencies haven’t caught up. Here’s what we’re actually shipping into production right now.
Models running on infrastructure you own. No data crossing your perimeter, no third-party prompt logs, no surprise vendor lock-in. Ollama, vLLM, Bedrock, or self-hosted.
Tool-using AI that acts inside your software — not beside it. Connected to your data, your auth, your business rules. Task-specific. Auditable. Stopped when the bill says stop.
Retrieval that respects your permission model. The agent sees what the user logged in is allowed to see — no more, no less. Standard chat-with-PDF tools cannot do this.
Audit trails on every call. Eval suites that catch drift before users do. Hallucination guardrails. Approval flows for production prompts. The controls regulators actually inspect.
Your jurisdiction, your encryption keys, your hardware. Built for businesses that cannot send customer data to a US-based foundation model. GDPR · POPIA · UAE PDPL aware.
Multi-user state synced over websockets. Streaming LLM responses with token-by-token UX. Edge inference for sub-100ms latency. Production patterns, not demo tricks.
Powered by leading AI platforms
RAG, MLOps, and governance — engineered into the software you already run. Not bolted on.
ISO 27001 · SOC 2 · GDPR. The controls regulators actually check — cleared on production systems.
What we ship
Backend, AI, security, databases, and sites that don’t suck. One senior team. No vendor tax.
Platforms that clear real money. Multi-tenant SaaS, transaction-grade integrity, services that talk across regulatory boundaries.
Private LLMs that don't leak. Agents that act, not chat. RAG over your own knowledge — sourced, cited, governed.
Pen-tested before you ship. Audit-ready by default. We've cleared the controls the regulator actually checks — not the ones on a marketing checklist.
Schemas that don't drop rows. Relational graphs for the data model you actually have. Vector stores wired to your knowledge, not someone else's API.
Sub-second loads. 100 Lighthouse. No templates, no page-builder dependency. Custom design systems hardened for Core Web Vitals and the next algorithm update.
The stack
No exotic frameworks. No vendor lock-in. The boring, battle-tested stack that holds up under real load.
Every line written from scratch. Deployed on your infrastructure. Owned entirely by you.
// ownership
No lock-in. No black boxes. Full source handover.
Speed is a feature
Sub-second loads. Real-time AI. Infrastructure that scales
before your traffic does. We don't optimise for benchmarks —
we engineer for the moment everything hits at once.
Hold to accelerate
Selected clients
MERJ Exchange needed a regulated securities platform. A travel-security operator needed a SaaS from scratch. A multi-language tour platform needed to take bookings online. They hired a technical partner.
The receipts.
AWS, Google, and Meta write the exams. We sit them. No agency-resale badges, no marketplace stickers — the certifications that buy you root access on production.

Yes. Every line of code, every design file, every API key, every deployment configuration. Full transfer on delivery. No recurring license fees, no vendor lock-in, no dependency on us to keep your system running.
Yes. We audit the current state — architecture, dependencies, technical debt, security posture — then propose a path forward. Whether that means refactoring, migrating to a modern stack, or building new features on top of what exists.
No recruiting. No onboarding. No managing. You get senior engineers from day one, across disciplines — frontend, backend, DevOps, AI, security. We scale up or down with the project. You own the output, not the overhead.
30 days of post-launch support included with every project. After that, most clients move to a monthly retainer for ongoing development, monitoring, and iteration. You can also walk away with everything — the code, the docs, the infrastructure.
Security is built into the development process, not bolted on after. Encrypted data, OAuth/JWT auth, RBAC, OWASP-aligned code review, and infrastructure hardened before deployment. We handle GDPR, PCI-DSS, and EU AI Act compliance for clients in regulated industries.
