About Kled AI
Kled AI operates 'the leading data marketplace,' sourcing what it describes as the largest licensable datasets on the planet from verified contributors around the world. Through its mobile app, everyday users upload photos, videos, and other personal or professional content (e.g., student work, photography, financial data) and get paid for it, while Kled aggregates and licenses this human-sourced data to leading AI labs, governments, and research institutions. The company also conducts its own research on data curation and model fine-tuning (e.g., its 'Uncanny Valley of Perfection' computer vision research), and maintains a token ($KLED) used as a rewards currency for contributors. Kled has raised $10M in funding, received a $3M investment from The DATA Foundation, and secured an $8M financial data request, indicating growth across enterprise, government, and research client segments. It is backed by a range of angel investors from entertainment, tech, and venture backgrounds. The company operates as 'A Nitrility Inc. Company.'
