It’s always interesting to know the (side) hustles people are running that, in their opinion, provides recurring revenue that is either a good source or passive income or their main source of income.

I'm at $1,000 - $1,500 range per month.

I run a free newsletter called Tech Talks Weekly[1] where once a week I send all the recently published software engineering and development conference talks and podcasts to my readers.

I'm offering a paid tier as well as sponsorship options, which together give me the above range.

Depends on what city and country you live in. Someone's $1k could be more valuable than another person's $10k

$0 so far (just launched).

I recently launched https://winlog.dev, a Slack-first tool to help engineers capture their work as it happens so they’re better prepared for reviews and promotions.

It’s early days, but I’m using it with my own reports and so far it's been really helpful. The goal for 2026 is to grow this into a meaningful side-business, but if not, then it's useful to me!

Enough to consider employing others to keep the business running without me, not enough to employ myself full-time, unfortunately. For the "from what?" bit, see my bio.
