Me and my team are struggling to get more signups to our API platform. So far we’ve managed to collect ~50. 5 of them tested our software thoroughly and seem to be really interested in buying the subscription. One of the channels that works good for us is just content e.g. on posts Stack Overflow or our profile at Programmable Web. However we get the feeling this is not the fastest way to attract new leads.
Now we’re wondering how to get in touch with software developers or CTOs at larger scale. We’ve submitted our product to Show HN, it’s even got to the first page but we ended up with poor signup rate. We’d like to ask for feedback on other developer communities related to e-commerce before we start cold emails. Do you know any?
