My SaaS Product has made $3,650 already 🀩 But there's a flip side to the story...


So, I released FeedHive in public beta 6 weeks ago. I think it's a good time to look at the total profit of my product at this very moment.And there's a flip side to the story πŸ˜‰In total, FeedHive has made:$3,650That's great. But let's take a look at some of the expenses.We got a UX Engineer involved, and he's currently building a new marketing website.It's really cool πŸ”₯ But we also had to pay him for his hard work.-$3,500For FeedHive, we're using Crisp chat. It's really adding a lot of value.But of course, we need to pay for a service like that. It's $30/month, and we've been using it for 3 months.-$30 * 3 = -$90In order to develop professionally, we're using a GitHub Organization on the paid plan. On GitHub, you pay $4 pr. member / month.Since we have paid yearly for 4 members, we spent around $300 on GitHub so far.-$300FeedHive runs on AWS. We architected the solution really well, but of course, there are still server costs. On average, we have paid around $1.6 / month in 3 months, so:-$5NB: It's worth noting that the average price of $1.6 included two months of closed beta. The price of February (the first month of public beta) was $3.74Now, stuff gets heavy! I canceled all contracts with my clients to go full-time on FeedHive.I'm only gonna look at the current month. I typically invoiced my clients $20K-$25K in total, pr. month.Let's make it an even $20K, for the argument here.I stopped working as a consultant on the 10th of March, so I'm estimating a loss in profit of $20K / 3 * 2 = $13K.So, let's break down the total expenses:-$3,500 -$90 -$300 -$5 -$13,000= -$16,895So, we can now calculate the total profit of FeedHive at this very point in time: $3,650 -$16,895= -$13,245Yup, that's right 😎 We're down with around $13K.Whenever you see people posting their MRR, remember:There's more to the story πŸ˜‰Do I still believe in FeedHive even though I've lost money so far? Yes, I totally do πŸš€ see hubwealthy.com/wealthy
