How a project runs

Understand
We learn how the work actually gets done, not how the org chart says it does.
- 2
Plan and price
You get a written scope and one fixed price before we start.
- 3
Build in short cycles
Working software to review every week. You make the calls on tradeoffs.
- 4
Hand over or keep running
Full handover with documentation, or an optional monthly plan.
Rent or own?
A quick check on whether a custom tool would pay for itself. Sometimes the honest answer is keep renting.
Owning pays off in
10 months
Then saves about $807 a month.
Includes $300/mo upkeep, staff time at $35/hr, and 8% yearly price increases. List your actual tools
Common questions
How long does a typical project take?
Most first projects ship in 2 to 6 weeks. Integrations run 4 to 10 weeks, and first versions of larger apps 2 to 5 months, delivered in phases so you see value early.
Why is this cheaper than other custom software firms?
AI handles a large share of routine coding and testing, so the same project takes far fewer hours. A senior engineer makes and reviews every important decision. You pay for judgment, not for typing.
Is AI written code safe to run my business on?
Only if someone experienced reviews it. Every line we ship is reviewed by a senior engineer and tested before it goes live. That is the difference between us and doing it yourself with an AI app builder.
Can you work with the tools we already have?
Yes, and that is usually where we start. We connect to common field service platforms, QuickBooks, Google Workspace, Microsoft 365, and most tools with an API.
