Great question and sadly, at the moment, we cannot find companies that have/don’t have mobile apps.
Our technographic data is all about what’s installed on their website or web app.
Our recommendation is to order a ListKit in your niche, then qualify the prospects by simply asking them if they have a mobile app. You’ll get more responses (which = higher deliverability for email sends), and you’ll be able to start the conversation smoother, in a non-salesy way.
