Build a whole company
from one sentence.

Describe the business you want. Builda builds it for real — the site, the working product, and the storefront that takes payment — then a whole team of AI teammates grows and runs it. You own it. It keeps compounding.

Free for 7 days. Build and grow a real company — no credit card, cancel anytime.

Already have a business? Put Big Dog — your AI sales engine — to work growing it. It supercharges your reps, handling the grunt work so they close more — without scaling headcount.

Not a website builder. Not a gimmick. Grounded in real data, so what it builds actually works.

One sentence in.
A living company out.

You want to start a company and make money — without a team, a developer, or months of work. Say what it is. Builda does the rest, and doesn't stop at a landing page.

1

Describe it

One plain sentence — the business you'd start if you had the time and the team.

"A subscription nootropic-mushroom coffee brand." · "A compliance monitor for independent HVAC contractors."
2

Builda builds it

A real company: a branded site, the actual product your customers log into and use, and a storefront that charges for real — grounded in live data so it genuinely works, not a mockup.

3

It grows itself

Your AI SDR team finds customers, writes the outreach in your voice, and closes it your way — a self-serve purchase on your storefront, or a qualified meeting booked onto your reps' calendar. Any industry. You get paid; it keeps compounding.

Meet the team that runs it.

Builda doesn't hand you tools — it staffs you a whole company. Each teammate does one job, and they work as one.

Not just a website. The whole company — idea to exit.

Most AI tools stop at a page and a mug. Builda walks you the whole way: fund it, make it legal, build the product, sell real things, keep the books, stay compliant, keep customers coming back, hire a team — and, when the time comes, sell the company. It opens the doors most founders never find.

Fund it
Grants & funding

Real federal grants and non-dilutive funding matched to your company and scored by fit — money you can get without giving up a share. Plus the path to investors when you're ready.

How funding works →
Make it real
Incorporate & bank

Form your LLC or C-corp, get your EIN, open a business bank account — the legal company, handled. Attorney, taxes, and the paperwork most people get stuck on.

How incorporation works →
Build the product
The working app

Studio builds the real app your customers log into — accounts, their own data, and a grounded assistant baked in. Ship it and your storefront flips from waitlist to real paid signups.

How Studio works →
Sell anything
Products & services

Ship real products with no inventory — or dispatch real service work (delivery, home services, on-demand labor) through nationwide networks. Physical goods or hands-on services, fulfilled for you.

How selling works →
Staff it
Hire & pay

Post roles to Builda's shared job board and get applicants straight to your inbox — Builda even tells you when your finances say you can afford a hire. Add employees or contractors, run payroll, pay people.

Run the books
Your automated CFO

A real profit & loss, per-product margin, cash and runway — built automatically from your sales, costs, and fees. No accounting software to connect. Plain-language advice on what to fix.

How the CFO works →
Stay compliant
Sales tax, handled

Flip one switch and Builda collects the right sales tax on every sale — calculated per the buyer's address, itemised on their receipt. The thing most sellers get wrong, done for you.

How tax works →
Keep customers
Reviews & retention

Rollo works the customers you already have — asks happy ones for reviews, nudges repeat buys, and wins back the ones who drift. Repeat revenue on autopilot, from your own address.

Sell your company

When you're ready to move on, list it on the Builda marketplace with platform-verified financials — not screenshots — and a valuation from your real numbers. Ownership transfers the moment you accept an offer.

Builda doesn't replace jobs — it gives every human the power to be a company. A neighborhood bar running tabs without a card. An artist. A landscaper or a plumber. A SaaS you built in another tool and now need to actually sell. A tire store, a course maker, a life coach, a quilt maker, a convenience store, a mid-size enterprise. If you can serve a market, you can build the company to serve it. That's innovation, democratized — and the real American dream, open to everyone.

The brain under it all

Real, not hallucinated.

Every teammate — what they build, sell, and say — runs on Cortex, Builda's grounded brain. It answers only from real, cited sources, or it tells you it doesn't know. That's the moat: your company, its product, and its pitch are built on truth, not a generative model's best guess.

Grounded, not guessing

Every claim traces to a primary source — or Cortex abstains. No confident fabrication in your numbers, copy, or advice.

A living expert matrix

7,759 grounded expert endpoints across law, finance, health, trades and more — live and growing.

It teaches itself

Ask something new and Cortex researches primary sources and stands up a fresh grounded expert on the spot.
