The term A/B testing gets thrown around a lot in startups, many use it to great effect, and some know they should use it, but never quite do. Our guest today is Chetan Sharma , Co-Founder and CEO of Eppo , a platform that helps companies run useful, reliable experiments by automating the analysis, diagnostics, and investigations, all on top of your data warehouse. We get into the power of A/B testing, how Eppo can unlock that power for startups of all sizes, and best practices for implementing them. About Chetan Sharma: Chetan Sharma is the Co-Founder and CEO of Eppo . Previously, he was Data Scientist at Webflow and Airbnb. Chetan worked in empirical healthcare policy, helping to craft metrics and incentive systems as part of the Affordable Care Act's pay-for-performance programs. He has BS and MS degrees from Stanford. A word from our sponsor: At Ripple, we manage all of our fund expenses and employee credit cards using Jeeves.  The team at Jeeves helped get me and my team setup with physical and virtual credit cards in days. I was able to allow my teammates to expense items in multiple currencies allowing them to pay for anything, anywhere at anytime. We weren’t asked for any personal guarantees or to pay any setup or monthly SaaS fees. Not only does Jeeves save us time, but they also give us cashback on our purchases including expenses like Google, Facebook, or AWS every month. New users can earn up to 3% cashback for their first 90 days. The best part is Jeeves puts up the cash, and you settle up once every 30 days in any currency you want, unlike some other corporate card companies that make you pre-pay every month. Jeeves also recently launched its Jeeves Growth and Working Capital initiative for startups and fast-growing companies to enable more financial freedom for companies. The best thing of all is that Jeeves is live in  24 countries including Canada, US and many other countries around the world. Jeeves truly offers the best all-in-one expense management corporate card program for all startups especially the ones at Ripple and we at Tank Talks could not be more excited to officially partner with them. Listeners of Tank Talks can get set up with a demo of Jeeves today and take advantage of our Tank Talks special with a‍ $250 statement credit after the first $2,500 in spend or a $500 statement credit after the first $5000 in spend. Lastly, all Jeeves cardholders receive access to their Lounge Pass program and access to over 1300 airports globally. Visit tryjeeves.com/tanktalks to learn more.
