Hey 👋 Quick story about why I put this together: I love sponsoring newsletters. They are an amazing way to find new customers. And there are many businesses eager to sponsor. But finding the right newsletters to book ads in is a laborious process. You contact dozens only to hear back from a few. The data you find online is often not up to date. At the same time, there are many amazing...

Hey 👋 I love building simple side projects that provide value to people. At the same time, I’m not a fan of offering free stuff if you have nothing to sell. So what I tried in the past is charging a little money for access to my side projects like Newsletter Spy or Product Explorer. This worked OK. But I was never able to grow them to a point where they generated significant revenue. It became...

Hey 👋 I started curating revenue numbers whenever I saw founder post them on Twitter, Hacker News, etc. a few months ago. Haven't talked much about the project so far since I first wanted to find out if the data collected this way is interesting at all. I find it really interesting to see how projects evolve over time and like that the raw numbers paint a realistic picture of what a typical...

I'm working on the second version of Under the Radar (https://undertheradar.io), an ever-expanding database of 10k+ under-the-radar markets, products, and investment opportunities. Biggest update I shipped is a detail page for each trend that shows more data.

Looks awesome! I'm using Ghost for my Founder Flywheel newsletter and can't wait to play around with all the new features. Especially being able to run multiple newsletters on a single site will unlock tons of new opportunities.

Hey PH 👋 I haven't launched anything in a while so I thought it's time for a fun weekend project. I already had a script that collects information on job posts on Lever job boards. (Honestly can't remember why I wrote it in the first place 😅.) And I wrote tons of trend detection scripts for another project of mine, Under the Radar. So I thought: why not combine the two? Job Title List is the...

Hey PH 👋 This is a tool I built to scratch my own itch. As for most people, my newsletter started with just my family and friends as subscribers. But now with thousands of subscribers, it has become quite difficult to develop any kind of understanding of who the people on my list are. There could be all kinds of cool people on my list that I should talk to. But I'll never know since all I have...

Hi 👋 Yesterday, I saw a cool project by @creative_octopus here on Product Hunt and it gave me the idea for this fun end-of-the-year project. Joseph used GPT-3 to generate product ideas for several serial makers. When I tested Joseph's approach myself I was surprised by how awesome some of the ideas were. For example, this is what I got for myself: - Alternative Data - Data and signals that the...

Hey 👋 Two days ago I saw an interesting discussion on Twitter [1] about alternative ways to uncover websites for sale. The idea is that just like in the physical world there are plenty of neglected properties online. Many sites of course get listed on the usual marketplaces but at least just as many never end up there. Sites not listed have the advantage that you don't have to participate in an...

Hi PH 👋 I recently launched VC Watcher and in the process wrote all kinds of scripts that I ended up not using for the project. So I had the idea to use them for another small project instead of letting them rot on my hard drive. VC Data is the result of these efforts. I'd love to hear what you think and feel free to ask any questions you might have!

Hi 👋 I primarily created this project to test some new technology I've never used before. But since I got some nice feedback from early subscribers, I've decided to share it here as well. The idea is quite simple. Each week, the script collects information on recent investments made by top VCs like Peter Thiel, Naval Ravikant, and Keith Rabois and then compiles an email which is sent to...
