About

Product designer since 2020, from LA to the Silicon Valley! I've been designing my own consumer products on and off since then, but couldn't find anything I wanted to commit to until Retrocodex: Stuff You Learned Wrong. It was inspired by a prompt on a viral social media post. I committed to making the site after I saw an Instagram comment on the post that said "I know I'm living life with an outdated operating system". I didn't want myself or anybody else to have that. I hope you enjoy the site and make an account to join the community of Unlearners! I'd love to know what myth bothers you most that's on the site -- if it's not there, please submit it!

What marketing strategies do you consider unethical, and which ones do you consider brilliant?

During today s standup meeting, an idea came up about improving our presence on Reddit (for LLM search visibility and similar reasons).

One of the suggestions was to look for high-karma accounts and possibly buy them to appear more credible when posting and mentioning the product within the posts/comments. It s a tactic, sure, but to me it already feels like it crosses an ethical line. I sometimes worry they can seriously damage a company s reputation.

Retrocodex - Fix outdated parts of your education and unlearn myths.

Many things you've been taught in school or everyday life is now outdated or was always a myth, like "you only use 10% of your brain". Retrocodex is a platform that documents common misconceptions and outdated information submitted by users from all over the world. What you learned often depends on where you're from, so follow other users who grew up in the same state or country as you to discover what your part of the world got wrong!

What was your initial motivation for starting a business?

People s motivations for wanting something of their own vary quite a lot.

So far, though, I ve most often heard these three answers:

To make a lot of money.
To work really hard until 30 so I can relax later in life.
Time and location freedom.
