Built by a surveyor

Built by a surveyor.

Brian Jaquess, PLS, spent 30 years in the field before he built the tool he always wanted, then brought in a small software and marketing team to finish it. Made for the survey and civil firms stuck adapting tools built for the big firms.

Datum30 years in the profession. One hub built to give you back your time.

Our mission

Build the hub that land surveyors and civil engineers actually use. Designed by people who have walked the lot lines and know what a paper field book is supposed to do.

Our vision

Every field crew running on a record that is complete and organized by project. Every office side seeing what the field saw, without translation. Every firm spending its time on work, not admin.

The founders

Field work, software, and business.

Three people with overlapping backgrounds and one shared frustration.
