Humor doesn't get you conversions, also you're not really addressing an audience that wants to buy devtools. Individual employees and even engineers often won't buy themselves devtools. You have to address management/executives if you want to sell them on your service, and fair warning; they hear almost 100 pitches a month sometimes.

At my old company we did some guerilla marketing on Reddit and got a post go mega viral (front page for 3 days) 15k+ upvotes.

For us it was a bit different because we were doing robotic F&B so people could come to our restaurant to see the place from Reddit IRL.

I would target memes in niche dev communities if you want direct outreach. Like if you're looking for people to test your product you'd have more luck on a 100 upvote post in some obscure deeptech subreddit then you would if your post got 10k upvotes on r/funny.

Sorry for any grammar mistakes - writing this on the rush hour train :)
