At Across, we wanted to see how many other technology companies and service providers we use on a regular basis. The answer was way more than we thought. For a seed stage 2 person startup, we already use 28 different tools regularly totaling $227 / month (we’re on the free plans for many of them). And, this excludes libraries in our product. It’s self-inflicted, but a lot of tools nonetheless.

I'm sure this number will grow as we hire employees and have to buy HR and IT software as well (and I'm sure I forgot a few existing tools on this list). We're interested to hear what other startup stacks look like!
