Professional geotechnical software at a fraction of the cost
Deep foundations, earth retention, slope stability, and more. A full suite of engineering software shaped with the real workflows of working geotechnical engineers in mind. GEOpetra was built to make you thrive.
Launching soon — sign-ups open shortly. Free to use at launch; pay what it's worth when you're ready.
The problem
Industry-standard geotechnical software is licensed per expensive seat.
Most firms own one — and it's always in use.
The alternative? Spreadsheets passed around the office, or waiting on whoever has the license. Engineers-in-training learn the method in school and then spend hours fighting unfamiliar software to apply it on a real project. There's a better way.
What's included
A growing collection of tools. One subscription.

Why GEOpetra
Designed for how engineers actually work
Priced for everybody
Free for now, under $50/month when subscription fees begin to apply. An individual engineer can subscribe without a manager's approval and without breaking the bank. No commitment; cancel anytime.
Report-ready output
Every calculation produces a formatted PDF with methodology references. Hand it to a reviewer or stamp it directly — no reformatting required.
Fast from day one
No multi-day learning curve. If you understand the method, you understand the inputs. Run your first calculation in under five minutes.
Methodology you can cite
Established design standards and published methods. Results reference the source — so your calcs are defensible when a reviewer asks.
More products coming
GEOpetra keeps expanding to cover more geotechnical design workflows. One subscription grows with the platform.
Developed with YOU in mind
If you have a pain point in your geotechnical workflow that an update or addition to our software could relieve, we want to hear from you. Our product gets better for everybody when you tell us what you're wishing for.
Tooltips, tooltips, and more tooltips
Our software is designed to help you master your craft. Most inputs in each analysis have helpful tooltips that explain what the input is and how changing it affects the design.
Pricing
Simple, transparent pricing
One plan. All tools. Free now, pay what you think it's worth after GEOpetra has improved your workflow, and then less than $50/month later when we implement subscription pricing. See full details →
