spline
Commercial preconstruction, re-engineered. Spline runs the takeoff, the pricing, the schedule, and the risk model — so your estimators ship defensible bids in days, not weeks.
The discipline
of estimating.
Estimating has been a craft of paper, gut, and rework. Spline replaces that with a system — agent-first, model-aware, evidence-bound.
We read the spec. We read the drawings — PDF, Revit, IFC, or CAD. We hold the product knowledge, the historical bids, the field data, and the risk in one place. The result: more accurate bids, shipped faster, with the kind of visibility general contractors actually need to make a call.
Built for commercial interiors and ground-up. Field-deployed 2026. Made in Kentucky.

What Spline does.
Spreadsheets compound risk.
Spline compounds discipline.
Every spreadsheet-driven bid carries the cost of yesterday's errors — and hides them. Spline turns the estimating function into a closed-loop system: every number traced to its source, every decision logged, every bid more defensible than the one before it.
Watch the bid
get built.
A real Spline session, replayed in miniature. Spline reads the spec, lines up the takeoff, prices the model, and assembles a defensible bid — while the estimator stays in the loop. Swap this section for a screen recording when you're ready; the section's data-mode attribute does it in one line.

Spline is not a demo. It runs inside a working commercial preconstruction firm, on real bids, against real deadlines. The dashboard below is a sanitized snapshot of one week of live use — project names, totals, and locations redacted.
Built in
Kentucky.
Spline was built in Shelbyville, Kentucky — between the tobacco barns, the thoroughbred farms, and the construction sites that make up Shelby County. It is field-tested inside a working commercial general contractor, on the kinds of bids that move buildings here.
We serve preconstruction teams across Shelby County, Louisville Metro, Frankfort, Lexington, and the central Kentucky construction corridor.

Building up Kentucky.
Spline brings agent-driven preconstruction to the commercial work that rises across the Commonwealth — more accurate, faster, and giving general contractors the visibility they actually need to make decisions.
Group
Built by estimators, not by demo decks.
Spline is not a SaaS pitch waiting for product–market fit. It was built inside Summit Flooring Group — a working commercial preconstruction firm in Shelbyville, Kentucky — and runs on their live bid desk every week.
Every capability on this page has been pressure-tested against real specs, real models, real deadlines, and real dollars on the line. When you bring Spline to your team, you're bringing a system that has already paid for itself on the kind of work you do.
SFG and Spline now extend that capability to peer commercial preconstruction teams across Kentucky.

next project
with Spline.
In collaboration with Summit Flooring Group (SFG), Spline is taking on a small number of commercial preconstruction engagements each quarter. If you estimate, manage, design, build, or engineer commercial work in Kentucky — and you've outgrown the spreadsheet — tell us about the project.
