Our mission
We've been in your shoes
The name started personal. Moss for patience and deep roots, Spark for engineering drive. But it describes how we work, too.
We've spent 15 years inside the same industries our clients work in: environmental compliance, construction management, and engineering. We've sat through the spreadsheet chaos, the Monday morning scrambles for project status, the RFQs that slip through the cracks. That's why the tools we build actually fit. We're not outside consultants guessing at your workflow.
Our mission is to build focused, dependable software that embraces automation to help small teams do their best work.
Featured work
Built for real workflows
Case Study
Rapid RUSLE
Erosion modeling, automated.
Environmental consultants were spending hours per project on manual RUSLE2 calculations — copying between spreadsheets, reformatting reports, and catching inconsistencies under deadline pressure. Rapid RUSLE replaces that entire process with a single web app: structured data entry, automated calculations, and audit-ready reports out the door.
