About the Company

Flai is a spinoff company of Flycom Technologies.

Flai develops a web-based application that automatically turns raw geospatial data into meaningful information. Point clouds, images, and satellite data are processed via advanced AI models – this complex work is done automatically on a scalable infrastructure which reduces time-to-process from months to days.

Our AI models are pretrained on multiple data sources and can be used for processing right away. Also, our solution enables additional training of AI models. All annotations done on the web application are automatically used to generate better results. Retraining the AI model greatly reduces the time and cost needed for quality control and manual edits.
