We rebuild how service businesses operate — replacing scattered tools, spreadsheets and manual work with custom software and AI engineered into the core. Systems you own, getting smarter every month.
Leads slip, documents get lost, and you can't see your numbers. The fix isn't another app — or a chatbot bolted on. It's intelligent systems built around how you actually work, with AI doing the heavy lifting where it earns its place. That's what we engineer.
The building blocks of every Sigma system. Each is a real capability with real clients — combined into one platform, built around how your business runs.
Your platform, built to last.
Custom SaaS, mobile apps, client portals, and integrations. Production-grade architecture purpose-built for your workflows. You own the code — no subscriptions, no vendor lock-in.
Engines built into your system — not bots.
AI that does a real job inside your software: assessment and scoring, operational assistants, decision and analysis engines. Trained on your data, running on our own infrastructure. The kind of AI that actually ships.
Embedded payments. Zero monthly fee.
Powered by Stripe Connect and Pagar.me. Every Sigma-built platform can ship with full payment infrastructure — cards, PIX, subscriptions, invoices, split, and accounting sync. Revenue from transaction volume, not monthly fees.
Intelligence that compounds every quarter.
BI dashboards, data warehousing, executive reporting, and a Fractional Data Office. Your leadership always has the number that matters — automated, clean, and current.
One door in, one relationship that compounds. Senior engineers, custom code, and AI where it earns its place — billed clearly, scope by scope.
We map your operation and find exactly where custom software and AI engines create real value. You leave with a written diagnosis and a prioritized plan — no commitment to build.
A defined new capability, shipped end-to-end: a system module, a client portal, or an AI engine built into your stack. Every new scope is its own sprint — clear price, clear deliverable.
Your embedded technical team. We run it, evolve it, and ship something new every month — with an SLA and a monthly roadmap you control. This is the asset that compounds.
Custom software and AI engineered into one system you own — Software, AI, Payments, and Data, working together. Not tools bolted together. A smarter way to run your business, compounding every quarter.
These are the actual platforms and AI engines we have designed and shipped. The product is real, the demo data is fictional, and each card below opens a navigable demo.
A lifecycle operations system for service businesses that need pipeline, tasks, conversations, SLA visibility, and account health in one place.
A spoken English assessment engine that scores fluency, pronunciation, and grammar, then returns a CEFR-aligned result in minutes.
A voice interview simulator that asks questions, listens in real time, and produces structured scoring and competency feedback at the end.
A multi-tenant WhatsApp AI assistant layer for support, lead qualification, scheduling, and knowledge-based answers across different businesses.
A government-contract sales CRM that organizes leads, proposals, deadlines, commissions, and delivery workflow in one operating system.
A fractional-CFO portal that turns monthly finance into understandable KPI reporting, projections, and action plans for clients.
Same flow whether it's a 2-week Sprint or an ongoing Partner engagement. Predictable cadence, decisive milestones.
We meet your operation. Map workflows, read the data, find where you're actually losing time and money — and where an AI engine pays off. Output: a written diagnosis and scoped proposal.
Decide the shape. Stack, data model, integrations, deployment target. You see the blueprint before a line of production code is written.
Engineers ship in small, reviewable increments. Weekly demos. Decisions logged. You stay close enough to redirect, not so close that you have to babysit.
Production deploy, monitoring, documentation, training. You own everything. We roll into Sigma Continuum — running it, evolving it, and shipping something new every month.
We start from how your business actually runs, then build the software and AI that makes it run better. Never technology for its own sake.
Full source, full deployment access, full documentation. No vendor lock-in, no recurring license fees on your own software.
We engineer AI into your system where it does real work — assessment, scoring, analysis — never a chatbot bolted on for show.
We architect for the next three years, not the next quarter. Type-safe, tested, monitored, maintainable.
Before this, we had no single place to see our business. Now everything — leads, operations, finance — is in one system we actually own. It changed how we run the company.
We were rebuilding the same spreadsheets every week. Now the data comes in automatically, the opportunities are scored, and our sales team just works the pipeline. Something we never had before.
We used to review every transaction by hand and still missed things. Now the system categorizes the routine, flags the anomalies, and sends us only what truly needs a human. Our monthly close is faster and the team is with clients, not spreadsheets.
I had a proven method but I was capped at one-on-one sessions. They built a platform that runs the whole practice — intake, progress tracking, and AI that turns each diagnosis into structured insight. I scaled to hundreds of clients without losing the personal touch.
Free 30-minute conversation. We'll tell you honestly whether we're the right fit, and if not, who is.
