Are we on track?

We developed an idea in late Feb. Put up a pre-launch sign-up page to validate the idea. Drove traffic via Reditt, Twitter and Betali.st. During last 2 weeks got over 800 uniques and over 200 sign-ups (24% coversion). Started an email campaign and have over 70% open rate, 0 complaints and 0 unsubscribes. We’re thinking that we are ready to launch the MVP and start the feedback loop to further develop the product as well as get more proof of concept. We feel like this is validation that we may be onto something based on the numbers and are on the right track. Would appreciate any thoughts or suggestions. Thanks.
