Custom SaaS Development
Built to Run, Not Just to Launch
For founders and mid-market teams who need a real SaaS — not a script. Multi-tenant architecture, subscription billing, GDPR and HIPAA-ready by default. Fixed-price from $3k, built by a team running 7 SaaS products with 13,000+ active users.
8–16 weeks
Launch, don't linger
SaaS MVP in 8–16 weeks, not 6 months. Fixed scope means day-one progress — no discovery tax, no moving targets.
From $5k
Transparent packages
Fixed-price SaaS builds starting at $5k. Scope published before a single line is written — no mid-sprint surprises.
SOC 2
Compliance by default
GDPR and HIPAA-ready architectures on every build. DPA on every engagement. Not a checkbox — an architecture decision made on day one.
Modern
Stack that scales
React, Next.js, TypeScript, Laravel, Node, AWS, Flutter — with AI-native integration available on every tier.
SaaS Engineering, End-to-End.
Six capability lines across the full SaaS lifecycle. Pick one or work with us across all six.
Multi-Tenant SaaS Architecture
Row-level or schema-level tenancy, per-tenant billing, isolated data stores, role-based access, and admin consoles — designed from the schema up, never retrofitted from a single-tenant codebase.
SaaS MVP Engineering
Fixed-scope MVPs in 8–12 weeks. React + Node or Laravel + Flutter. Purpose-built foundations for eCommerce, marketplaces, on-demand services, and B2B platforms — real code that scales, not throwaway prototypes.
Payments, Billing & Subscriptions
Stripe, Paddle, and Lemon Squeezy for global billing — Tabby, Tamara, Mada, and STC Pay for GCC markets. Usage metering, free trials, dunning workflows, refunds, and revenue recognition, all wired from day one.
Compliance-Ready Builds
GDPR, HIPAA, and SOC 2-ready architectures with audit logs, data-residency options, threat models, and a signed DPA on every engagement. UK Ltd, US Delaware C-Corp, and UAE DMCC entities available for local procurement.
AI & LLM Integration
RAG pipelines, agentic workflows, eval harnesses, and LLM retrofits for existing SaaS platforms. Anthropic Claude, OpenAI, LangChain, Pinecone, pgvector — with observability and a real ROI model, not just a chatbot bolted on.
DevOps & Managed Hosting
AWS, Azure, and GCP infrastructure as code, CI/CD pipelines, observability dashboards, cost optimisation, and post-launch SRE retainers. Your SaaS stays up, performant, and cost-efficient after we hand it over.
SaaS products, custom web platforms, mobile apps, and AI agents. From-scratch builds with published scope, fixed pricing, and a committed delivery date.
Problem validation, ICP definition, competitive mapping, feature prioritisation, and a signed scope document — agreed and locked before a single line of code is written. You leave the discovery sprint with a fixed price and a launch date.
Wireframes, a component library, and a production-ready Figma system — every screen and every interaction approved by you before development begins. No mid-sprint design pivots. No surprise rework costs.
Sprint-based builds with weekly demos, full test coverage, CI/CD pipeline, and a staging environment you can access at any time. Your feedback is logged and resolved before the next sprint opens — same team, start to finish.
Production deploy, DNS cutover, observability wired (Datadog / Sentry / PostHog), and a 30-day post-launch warranty. We don't disappear after go-live — we're on call through the first month and available for ongoing SRE retainers.
From Idea to Execution
SaaS products, custom web platforms, mobile apps, and AI agents. From-scratch builds with published scope, fixed pricing, and a committed delivery date.
01. Ideate
Problem validation, ICP definition, competitive mapping, feature prioritisation, and a signed scope document — agreed and locked before a single line of code is written. You leave the discovery sprint with a fixed price and a launch date.
Where Code Meets Conversion.
Custom-built websites with measurable outcomes. From-scratch builds with published scope, fixed pricing, and a committed delivery date — shipped, scaled, and proven in production.
AI-Powered Customer Support SaaS Platform
A self-hostable, multi-tenant Laravel platform with semantic AI chatbots, support ticketing, knowledge base builder, and Stripe billing — a full alternative to Intercom and Crisp that clients own outright.
Multi-Tenant eCommerce SaaS
A single Laravel instance powering 50+ independent online stores — custom domains, 19+ payment gateways, Flutter mobile apps, and per-tenant branding.
Crowdfunding & Donation Platform
Laravel crowdfunding platform with drag-and-drop campaign builder, event ticket sales, 10+ payment gateways, and a configurable platform fee model — built for full operator control.
Security is Not a Phase Two Concern
Every engagement ships a DPA. Every architecture ships with a threat model — an honest roadmap, not marketing badges.

Real Questions. Real Answers.
The questions every SaaS buyer actually asks. If yours isn't here, ask it on the call — we'll answer it honestly.
Our fixed-scope MVP packages run 8–12 weeks from signed scope to production — a full multi-tenant SaaS with mobile app and compliance takes 14–20 weeks. We publish the milestone list on day one and commit to a launch date in the proposal, not a rolling estimate.
