Experienced founder manages your project directly
When you partner with GEOSLN, you work directly with our founder, Kevin Mercy. Our founder has made a career specializing in data pipelines, GIS, cloud systems, and production apps. Whether it’s a basic development feature or a production deploy, we can provide a retainer or quote to meet your business needs.
Our business model
We offer several retainer sizes and technical audits for clients to choose from. Bigger or more custom projects will be quoted following your free consultation.

Frequently asked questions
Before you book
- What kind of companies have you worked with before?
- GEOSLN has mainly supported small businesses. We have primarily helped organizations automate processes they already had, or that were slow. GEOSLN has helped several organizations go from idea to MVP.
- What should I bring to the first call?
- Please be prepared with the issues or problems your organization is struggling with. We can help decide a retainer type or recommend a technical audit. The more tangible information we can discuss in the call, the easier it will be to quote your project. We will follow up with our retainer and/or audit recommendation shortly after.
- Can we pay hourly?
- GEOSLN is focusing on value-based contracts and is reserving more traditional hour-based contracts for larger or bulk projects. While our core business model is becoming more project-based, we may be able to reach agreements following consultation calls.
- How do contracts and payment work?
- Every engagement has a simple written agreement. Retainers and audits are paid in advance through a Stripe or Relay payment link. If plans change, what you paid carries over to the next piece of work instead of being lost.
