Thinks. Learns. Runs.Just like you would.
Mainstae is a second brain for your business — it senses what’s happening, decides what to do next, and runs your storefront, your Instagram and your billing the way you would. You just approve from your phone.
4 decisions — 30 seconds
Running a small business is a hundred small things nobody warned you about.
Ever wanted a website and a real Instagram — but never found the weekend to build either?
Mainstae ships your storefront and runs your feed. In your voice, on your domain, live in an afternoon.
Two full-time jobs. One of you.
You’re running the counter and the whole business behind it. Watch what shifts the moment a second brain kicks in and starts thinking alongside you.
- 6:30 AM
Open up. Prep. 12 DMs already unread on Instagram.
- 11:00 AM
Rush hits. The post you meant to schedule never went up.
- 2:00 PM
A regular asks about Sunday hours. You’ll answer later. You won’t.
- 7:00 PM
Close up. Now the invoices. Now the reviews. Now tomorrow’s promo.
- 11:30 PM
Bed. Tomorrow starts in 7 hours.
Not another app. A mind for your business.
Talks to every one of them, in your voice
DMs, messages, calls — answered instantly, sounding exactly like you. The ones only you can handle come straight to your phone.
Turns your Instagram into a growth engine
Posts, stories, reels and promos — written from what’s actually working. Your feed shows up, on time, every week.
Spins up a real storefront, on day one
Site, menu, hours, booking — live in minutes. Rewires itself the moment anything in the business changes.
Chases the money so you don’t
Invoices out, reminders sent, receipts filed. You get one clean weekly read on what came in and what’s coming.
Reads the room before you can
A quiet Tuesday, a slipping review, a supplier drifting late. It spots the shift and moves — you just get the heads-up.
One phone. One tap. Full control.
Everything it did today, everything it’s about to do tomorrow — one screen, one thumb, done.
A living brain for your business.
Four faces, one mind. It senses. It decides. It acts. It learns. The same instincts you’d use to run the place — switched on, all day, every day.
It sees the whole business at once.
Every DM, booking, payment, review and quiet hour — picked up in real time. The stuff no owner has the bandwidth to track.
Small businesses thinking bigger.
“We had no website and I was posting on Instagram at 11pm. Now Mainstae runs both. I bake.”
“It answers every DM before I even see it. Books the appointment. Sends the reminder. I just cut hair.”
“I got my Sundays back. That’s the whole review. My Sundays.”
Three moves. Then it thinks for itself.
Plug in
Connect Instagram, Gmail, Stripe, Square — whatever you already use. A handful of questions and it’s awake.
Watch it think
It reads the business, drafts the storefront, plans the week and starts making moves — all in the first afternoon.
Approve & go
One tap ships it. One tap edits it. You’re still the owner — you just stopped being the bottleneck.
Everything you were going to ask.
Neither. Mainstae is an autonomous operator — a mind for the business. It thinks and moves on its own. You don’t build workflows or write prompts. You just approve.
Give your business
a mind of its own.
Free while you’re in the founding cohort. No card. No contract. Awake and working before your next coffee.
