Two words, defined.
- agentnoun
Software that works toward a goal you give it. You say what you want done. It figures out the steps, does them, and tells you what it did.
It can only do what you've let it do. Some things, like sending a bill to a customer, it has to ask you about first, every time.
- Thirteennoun
A construction platform where your agents and your people go to work. Your jobs, your customers, and your paperwork are kept there.
Anything you can do in Thirteen, an agent you've allowed can do for you.
What can agents do for me?
The part of the job that isn't the job. Estimates. Proposals. Change orders. Invoices. Receipts. Hours. The follow-up you meant to send. The thing you'd do tonight if you weren't so tired.
An agent takes that off your desk. Not by making it faster to type, but by doing it. You say "invoice the Hill Road deposit" and an invoice shows up, ready for you to send. You forward a photo of a receipt and it's filed to the right job.
And it doesn't just do what you ask. It has your whole record in front of it, so it can tell you which proposals have gone quiet, or what you spent on a job that never made it into a change order. The questions you never have time to ask, it can answer.
That's why it matters. Not an hour saved on a form. Evenings back, and money that was leaking between the site and the office.
What can Thirteen do for me?
Keep every job in one place. The estimate, the proposal, the change orders, the invoices, the receipts, the hours, the photos, and the messages with the customer. Open the job and it's all there.
Run the office without an agent, if you'd rather. Write the estimate yourself. Send the proposal for signature. Photograph a receipt and it's read and filed. Thirteen is a full construction back office on its own.
Give your agents hands. Anything you can do in Thirteen, an agent you've allowed can do too, through the same doors, with the same limits. A chatbot can tell you how to write a change order. An agent in Thirteen can write it, send it to the right customer, and file it to the right job, because all of that is already there.
And you decide how far it goes. Drafting, it can do on its own. Sending, when you say. Money, signatures, and the contract are yours every time, and Thirteen enforces that, not the agent's good behavior.
Where this came from.
Jonathan and Ryan spent a year on a few startup ideas that didn't work. Then they spent six months inside three construction offices, doing the estimates, the change orders, the invoices, the receipts, the hours. Most days there was a fire. Every fire made Lucile do something new.

GRC General Contractor
Gerver, founder
Receipts and photos
Came from cleaning up Gerver's office. A truck full of receipts and a phone full of photos, none of it filed to a job. So Lucile learned to read a receipt and put it, and the photo, where it belonged.

WG Buildings
Walter, founder
Change orders
Came the day Walter hit a hiccup. The office went from six figures to seven while they were in it, and a change nobody wrote down is how that kind of growth loses money. So Lucile learned to write one up and get it signed.

Four Winds Construction & Tile
Jessica, founder
Estimates
Came when Jessica turned out to run her business with scientific rigor, and Thirteen had to match it. Every line priced, every assumption written down. So Lucile learned to build an estimate the way she would.
We still run our office on it. There's nothing in here we didn't need ourselves, and nothing we needed that isn't in here.
How we speak to
Lucile, our agent.
Wednesday
Text it what you need, like you'd text your foreman.
