For crews, plans, and work that keeps moving
Build the tool your business actually needs.
Custom software built around how your business actually works — flat priced, delivered quickly, and owned by you.
Hi, I'm Win.
I started Promptful because I kept meeting good business owners whose days were held together by workarounds, disconnected systems, and memory. I like learning how people really work, then making the complicated parts feel simple.
Read Win's storyWhat I've Built
Crews aligned. Plans compared. Jobs moving.
Field crews, tracked in real time
Clock-ins, GPS verification, and work orders across two languages, replacing phone calls with real-time visibility.
View the workPlan comparisons, built in one click
Replaced manual plan comparisons with a tool that pulls plan data side-by-side and generates client-ready recommendations.
View the workJobs and crews, finally in sync
Replaced scattered updates and memory with voice-controlled job logging and crew management, running in production in weeks.

In business terms, not technical. We understand where work slows down.
I Build
React, TypeScript, PostgreSQL. No vendor lock-in.
You Use It

You’ll know the price before we build.

Business App
Operational System
Need clarity before a build?
Start smaller with a focused audit or flexible advice from Win.
Operations Audit
$1,500Win maps how your business actually runs, finds the friction, and identifies what is worth building or fixing. You get a clearer operating picture and a practical next-step plan, even if you never move forward with a full build.
If you do decide to build, the audit cost credits toward any build.
Consulting Hours
$175/hourGet flexible, advice-first help from Win. Use an hour to work out what kind of app or tool you actually need before committing to a build, or get practical guidance on implementing AI with no app or build involved.
