I've been working with Darwin since it was first released in early 2018. They are always willing to help me out if i have any issues or questions about how their product works. The support team is amazing! Very helpful and quick to respond when you need them. Their customer service has made our lives so much easier with this software. It's helped us cut down on time spent writing code which allows more time doing what we do best - creating great products that make a difference. Nothing really but all around good experience with Darwin! We use Darwins machine learning toolkit to power a range of applications ranging from image recognition (tagging) through to sentiment analysis.
