Bring project and portfolio costs together so teams work from the same institutional knowledge—not disconnected files and individual memory.

Aestor is construction cost intelligence software for owner-side teams, turning project history into traceable benchmarks for faster project and portfolio decisions.

Three principles hold the cost record together: what a team can see, what every number can be traced back to, and what gets sharper each time the record is used.
Bring project and portfolio costs together so teams work from the same institutional knowledge—not disconnected files and individual memory.
Keep estimate lines connected to source files, comparable projects, assumptions, and adjustments—creating a record teams can review and audit.
Each estimate and closeout you add becomes a comparable for the next—so benchmarks tighten and the same question takes less work than it did last quarter.
Aestor shortens the path to a first estimate while keeping the source and assumptions behind each figure within reach.
Closeouts, bid tabs, and consultant estimates—PDFs and spreadsheets, in the formats your team already uses. No template to fill in first.
