Engineering the world's wind data.

We are the independent party in the room — and the only number everyone agrees on. We hold no position in the outcome, so OEMs, owners, lenders and independent engineers all work from the same VOTC dataset.

We don't just measure. We build the whole chain.

Guyed lattice masts to 170 m — designed by our in-house structural team, manufactured near Pune, installed and commissioned by our own certified crews. One accountable party from the first calculation to the commissioned, signal-live mast.

Met masts and LiDAR, ground to hub height. Thies First Class sensors, Ammonit logging — every serial tied to its calibration certificate, so the dataset survives an independent engineer's review.

Where is the site — and what must the data prove?

Tell us where the site is and what decision the data has to support. We'll come back with a measurement scope, a programme and a price. Parties whose interests don't align, working from the same dataset.
