I just sent my single client a monthly subscription link via stripe.

$875 a month for service and support on a custom built loyalty platform.

Make about $25K up front to build it, then followed up with maybe another $20K worth of various features over the last ~5 years

Starting this month $875 a month to keep supporting them and helping grow his vision (credit management for events...ie: get a nfc wrist band at a party as part of an all inclusive package, has $xxx.xx worth of credit, tap your wrist band to pay)

i'm also starting to try to bridge this out as a more generic platform and look for new clients.

$875 a month in the USA is a nice bit of extra cash. Server costs are coming in around $300 because I haven't optimized aws and there are some legacy systems I'm supporting(VPC costs are killing me) but it'll be nice to have some extra cash to pay off some debt and maybe buy some things to fuel new hobbies.

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

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.

$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.
