Old Reliable came on board to increase our development capacity at a critical time for Risk Ledger. They rapidly developed a proof-of-concept natural language processing tool, then developed it into a cloud micro-service which integrated easily into our existing system. Our clients have been screaming for this tool - now we're using it to make their lives easier. A massive value-add for them and us!
