MainGrid builds custom AI agents and software for small businesses — delivered by senior engineers from the world's leading tech companies — then trains your team to run it.
Flagship — AI Front Desk
Almost half of calls to small businesses go unanswered — and most callers won't leave a voicemail, they just call your competitor. MainGrid's AI front desk answers 24/7, everywhere your customers already reach out: on the phone in your business's voice, in a chat bubble on your website, and on WhatsApp. It greets them, answers questions about your services and prices, books real appointments into your calendar, takes messages, and hands off to a human when it matters — one dashboard for every conversation, no matter the channel.
Connected live to your calendar and hours — on the phone, in chat, or on WhatsApp, it offers actual open slots and confirms on the spot. Double-booking is impossible, and every booking lands in your inbox and dashboard instantly.
No porting, no paperwork: forward your missed calls and the AI catches only what you can't — or get a brand-new local number in one click. Your team answers when they can; the AI never lets the rest go to voicemail.
Full transcripts, bookings, and messages from every channel in one place — urgent ones flagged and emailed the moment they come in. You'll never wonder what happened with a customer again.
One line of code adds it to your website — the chat bubble on this very page is the same technology. Give customers your WhatsApp number and it answers there too. Same brain, same bookings, same dashboard as the phone agent.
Phone agent: from 40¢ per answered minute, prepaid. Website chat & WhatsApp: a flat $29/month. No contracts, no seats, no monthly minimums — mix and match what your business needs.

Get yours — book a free callWhat 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.
iOS and Android apps from one codebase — from booking apps to full marketplaces with live video, real-time chat, and in-app checkout. App Store and Play launch handled for you.
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.

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 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.
Questions
An AI that answers your business 24/7 — on the phone, in a chat bubble on your website, and on WhatsApp. It greets customers with your script, answers questions about your services, books real appointments into your calendar, takes messages (urgent ones flagged and emailed instantly), and transfers to a human when needed. Every conversation, on every channel, lands transcribed on one dashboard. Call the phone version right now: (737) 353-1001 — or use the chat bubble on this page for the website version.
No. Most clients keep everything as-is and simply forward missed calls — your team answers when they can, and the AI catches only what would have gone to voicemail. Prefer a fresh line? We provision a local number in one click.
Both — pick either or both. The website chat widget is one line of code on your site; the WhatsApp agent answers on a number you give your customers. Same configuration, same calendar, same dashboard as the phone agent — set up once, answers everywhere.
Phone agent: from 40¢ per answered minute, prepaid — you load credit, it drains only when the AI is actually on a call, and it tops itself up at a threshold you control. Website chat & WhatsApp: a flat $29/month. No contracts, no seats, no monthly minimums — take one or both. Setup is a one-time fee after your free strategy call.
We build custom AI agents, web and mobile software, and workflow automation for small businesses — then train your team to run it. The same engineering bar you'd expect at a large tech company, sized for your business.
Every project is fixed scope and fixed price, quoted after a free strategy call — no hourly surprises. Pricing is sized for small businesses, and you approve the scope and price before any build begins.
You get a working, clickable prototype in days. Most production builds launch in weeks, not months, because we work in focused, fixed scopes.
Yes — you own 100% of the code and every account. No lock-in. And we train your team to run what we build, so you're never dependent on us.
Small and mid-sized businesses — local services, e-commerce, clinics, professional services — that want enterprise-caliber software and AI without an in-house engineering team or an agency's overhead.
We're based in Austin, Texas, and work remotely with clients across the United States.
