After a few weeks sketching and refining problem statements and arriving on some potential solutions (and day-jobbing and raising a kid), it's long since time to take the pulse of the market! I pushed up a landing page at the domain root of https://todaybuteasy.com after collaborating with founder friends that I respect, and am reasonably happy with the content.
In parallel, I launched (my very first!) Google AdWords campaign. That's been...less impressive. Over 20,000 impressions in, and I've got about 22 clicks and zero signups. That's not enough data to say if my landing page is any good, but it's clear that my AdWords targeting needs work--so that's my clear next step!
