Our goal at Tiingo is to bring top quality data to all. We’re former quantitative traders who understand the importance of good, clean data. We’ve built our own network connectivity infrastructure right at the exchange data center, crawler farms using NLP we’ve been studying for over a decade, and API so you can get better structured, faster, and more accurate data.
For some of our data sources, we come across vendors who pass our rigorous test. We speak with them, learn their process, and then run our own checks. When possible, we combine them with different vendors that cover the same dataset, and then cross-reference them automatically to ensure they stay accurate.
