Tulsa, Oklahoma
Custom software for companies in Tulsa, Oklahoma.
21 Solutions builds the custom software a company runs on. The team works from 12 N Cheyenne Ave in Tulsa. We learn the business, decide what is worth building, write the code, and stay after launch.
You hire a technology team. You stay the founder. You do not have to be the CTO, and you do not have to manage the engineers.
We build up to 3 prototypes per month.
Who this work is for
A fit
- A startup building its first version.
- A business with customers that runs on software.
- A multi-site business that runs on software at scale.
- An owner who wants one senior team to decide and build.
- Software the company actually runs on: the workflow, the platform, or the system that would hurt if it stopped.
Outside this work
- A marketing website.
- A class project or a side project.
- A single feature, or the cheapest hourly developers.

The team is in Tulsa
You work with the people making the technical decisions. The same team also works with companies elsewhere in the United States.
Custom software development in Tulsa means the software your operation runs on: internal platforms, the workflow that still lives in spreadsheets, a rebuild of a system that costs too much to change, and the connections between tools you already pay for.
Questions we get before the call
Do we need custom software?
The front door is a working prototype of one workflow, and only if the Prototype Review says we should build it. We will say no when connecting tools you already have, a process change, or nothing yet is the better move.
Are you a custom software development company in Tulsa?
Yes. 21 Solutions is based at 12 N Cheyenne Ave, #319, Tulsa, OK 74103. We build the custom software a company runs on. You work with the senior team that decides what to build and writes the code.
Who is this for?
Startups building a first version, businesses with customers, and multi-site businesses that run on software at scale. A marketing website, a class project, a side project, and a single feature are outside this work.
What is the prototype?
One working piece of your software, built in about 2 weeks. You apply, then we talk for 30 minutes. Then pick a plan: Startup $5,000, Business $10,000, or Enterprise $20,000 a month.
What happens after launch?
We stay involved. We fix, improve, support, and keep making technical decisions as the business changes.
Do you only work with Tulsa companies?
The team is in Tulsa. We also work with companies elsewhere in the United States.
