Exciting, innovative, world-changing technology that connects people to nature to save life on Earth.
Our portfolio
Raising the value of nature through innovative technology
- The Bio-Expertise Engine: An Artificial Collective Super-Intelligence (ACSI) platform that engages expert communities to score nature observations and reward expertise. The system is finding a new species, undescribed by science, almost every day.
- QuestaGame: A popular mobile game that turns nature discovery and education into the adventure of a lifetime. Available on iOS and Android devices.
- BioSMART: A dynamic, real-time bureau of global nature data. The BioSMART technology connects global nature data systems – and their communities – in real time, to produce the most accurate and comprehensive measurement of natural capital.
- IndigiQuest (coming soon): Helping bring indigenous knowledge and science to the forefront of natural capital valuation and management.
- Guardians of Earth. A real-world AR game that engages players in nature conservation.
“QuestaGame engages people – young and old – with nature, awakening a deep appreciation for all the amazing life forms, often found in their own backyards. It not only transforms players into researchers, scientists, custodians of life on Earth, but importantly contributes to official citizen science portals recording actual sightings so that it is so much more than a game.”
