About

I'm Paul. I build Finishwork.

I'm a licensed civil engineer in California, and I write software. Finishwork is made by Cresalto, my small company in the Bay Area.

What I've done

I've run construction jobs and designed structures. I've also built large software systems.

Why a proposal

A contractor can spend hours getting a price right. Then it goes out as a table of line items. The customer has to guess at the rest. Did they understand the job? Who will be at the house? What isn't in the price?

One general contractor put it this way:

“We win about two out of ten. The proposal is the most important document we send.”

Finishwork takes the estimate you already priced and turns it into a proposal that answers those things. Your customer opens it on their phone.

How I work

For your first five bids, I build every proposal myself. You send the file, and I send it back within three business days. I set up your company too, from your website and a few old proposals.

I ask two things back. Tell me what's wrong with it, and tell me when you win one.

What the AI won't do

  • It won't make up a price. Every number comes from your file or from you.
  • It won't write a review. Your customers' words go in exactly as they wrote them.
  • It won't touch your math. It checks every subtotal against yours, to the cent.

Cresalto

Cresalto is the company. Finishwork is what it makes. You can meet the rest of the team at cresalto.com.
