AI Agents · Custom Software · Team Training
MainGrid builds custom AI agents and software for small businesses — delivered by senior engineers from the world's leading tech and payments companies — then trains your team to run it.
What we build
Agents that actually work your queue — answering customers, chasing leads, processing documents, keeping systems in sync, 24/7. The same builds shipped for enterprise companies, sized for yours.
Web apps, customer portals, dashboards, and integrations — built around how your business actually runs, not how a template thinks it should.
Hands-on workshops from a former software-development instructor — so the tools we build (and the AI you're hearing about) actually get used.
How it works
A free call to map where your business loses time and money — and where software or AI pays back fastest.
You get a working demo in days — something you can click, not a slide deck. We refine it together before committing.
Production-ready software, integrated with the tools you already use. Fixed scope, fixed price, no surprises.
Your team learns to run it — with real training, not a PDF. You own the code and every account.
Proof of work

Training
Most "AI training" is a slideshow. This is hands-on, project-based, and built on years of classroom experience taking complete beginners to shipping developers. Your team leaves with automations running — not notes.
Half-day workshop: what AI can (and can't) do for your business, hands-on.
We take your team's real weekly tasks and automate them together, live.
From fundamentals to shipping AI features — for junior devs and career-switchers.
Who's behind it
MainGrid's engineers spend their days building for some of the biggest technology and payments companies on the planet — and bring that same engineering bar to your business. No account managers, no outsourcing chains, no juniors learning on your dime: the people you talk to are the senior engineers who design, build, ship, and teach.
A free 30-minute call. You'll leave with a concrete plan — whether or not we work together.
