Show HN: HissingKitty – what teams pay for software and what replaced it

Have spent the last 20 years building and launching software in some of the biggest companies in the world. Every week I hear people debating "build vs. buy" or someone bragging about how much money they saved building custom tech in house.

I think we are going into a 2027 that will be somehow even more confusing than 2026, and I wanted a place that had more data and facts and less opinions. Hopefully over time we can aggregate enough real data to build consensus.

The data comes from real people, real posts, listings from builders, and sourced stories. While one of them alone might exaggerate the truth, over time it will be obvious when you average out the data.

Just getting going with this, so would love feedback. And if you are building your own platforms, or have data to add, feel free to add it. In some places data is still thin, but I'm adding more to it each day.

Thanks for your help in getting more data out there and less opinions on the whole "build vs. buy" conversation when it comes to software platforms.

I can't get our CEO to replace anything. We pay for 100 tools, including 3 CRMs. Somehow we use Salesforce, Hubspot, and Monday.com
