My eSIM app makes 2x my SWE salary – here is how I found the first 100 users for it I launched my first app @yadaphone when Skype closed down and scaled it to $15,000 per month alone. 6 months ago, I decided to launch another business – an eSIM service called eSIMPal. I felt super nervous – I was afraid it would flop, and that would mean my first app was just a matter of luck. For the launch, I used all the lessons I learned from my first business. And it worked – in 6 months, @eSIMPalx ended up making $5,600/month – 2x what I was getting as a software developer Here is exactly what I did: 1. The X launch post I spent 4 hours writing the 200-word launch post. First I dumped all my thoughts about the products into the editor – it was about 1000 words. I thought about who the users would be, how I could differentiate from a red sea of other eSIM providers, and most importantly – why people would trust me. I am a frequent traveler, so I used this as a hook (the link to the post will be in the comments), then I talked about the competition, why they suck, and why my app doesn't. I also attached two photos with my face in the travel context (super important, adds credibility). This was a pure marketing launch post, I didn't pay for any boosts – and it got 332k views. The follow-up post got 200k views. The 500k combined views led to 70 signups, 45 payments, and ~$800 in revenue. Some of the users from this batch are still buying eSIMs for their travels from my app! People started interacting with eSIMPal, I got first purchases, and most importantly – the users pointed out what was wrong with the app. Two pain points were my pricing for some destinations and the lack of regional packages, so I spent the next couple of days fixing that. 2. Marketing on Reddit During the first week after launch, I showed up in every possible subreddit about eSIMs and travel. I made a lot of mistakes – I used shady marketing practices, like astroturfing, and of course got banned a lot. I got around 30 clients from marketing on Reddit this way, but I actually don't recommend it to anybody – shady marketing means you will be fighting with the platform, and it's an uphill battle. Much better is to write actual useful content, help people, and let Reddit help you in return. 3. Network As I mentioned, I already had a working product called Yadaphone when I launched eSIMPal. Yadaphone is a website to make cheap international calls; the niche was practically the same. So I used the existing network of affiliates and users – I texted affiliates to see if they would be interested in promoting eSIMPal as well, and let the users who might be interested in eSIMs know about eSIMPal. In the first week, this brought around 20 users – but the numbers were much bigger in the long run. If you don't have an existing product, use your family, work/friend chats – basically anywhere where people already know you, and you don't need to cold pitch them. I hope this post was helpful to anybody preparing to launch their first business! Links to everything are in the thread
