When you can't find the software you need,
we build the software that fits.
How we build it this fast — without cutting corners.
A working prototype in two weeks for $5,000 sounds too good to be true. Here's how it's actually possible — and why what we build holds up in production:
The prototype is the spec
No up-front documentation marathon. We build a working prototype and walk you through exactly how it behaves — then that prototype becomes the specification our production team builds from. What you're shown is what gets built. Skipping the written-spec phase is the biggest single time-saver — a new, AI-era way to build software.
AI speed, production discipline
AI is what makes the two-week prototype possible. The same team and rigor behind ESPCalcs and ESPPortfolios then builds the production system — to SOC 2 Type II compliance. AI makes the speed possible; our people make it production-grade. Speed without slop.
A purpose-built foundation
ESPCalcs, ESPPortfolios, and ESPProjects gave us battle-tested patterns — calculation engines, workflow, reporting. We've built those patterns into a new foundation purpose-made for fast custom work. Your Quick Build assembles on top of it. We don't start from a blank file.
We understand your world, not just the code.
We've spent years building software for energy efficiency — ESPCalcs, ESPPortfolios, and ESPProjects — so we already speak your language: rebates, measures, cost-effectiveness, day-to-day operations. We start from the problem that's actually yours and get to a solution that fits how you really work.
