dude everyone is building the most boring tech out there. I'm convinced there's not enough space for this many ai for accounting startups in the market.

My favorite question to ask early stage startups during an interview is what’s their gender split 🤭

got an email from @weebly today letting me know that they will stop hosting my site... my first thought was, which site?? turns out that 10 years ago I created a page dedicated to Cephalopods 🤓👆🏼 (octopuses, squids, etc.)
appreciate the pre-AI grind 🐙

Are you angered when you see AI posts?
Do you get value from certain AI posts?
Maybe you're just generally opinionated about this topic.
Tell me what you think (takes 1 min to complete):

I'm fascinated by the whole friction reintroduction phenomena, especially if it's promoted by tech startups like @UseCorgi

how do you politely tell someone that they need nose surgery? I can hear this guy breathing from the other side of the room

went mildly viral on linkedin last week for posting a picture of me handing out a one-pager to a cto explaining why he should hire me… and well, I have some thoughts.
every startup out there says they want people who didn't take the ordinary path, but then their JD says “ex-consulting, PE/VC, or IB preferred.”
i don't have any of them, and it feels impossible to break through these barriers. the job search has completely dismantled my self worth and made me question every single decision I’ve taken.
why didn’t I just do one year of consulting? Instead of moving to Berlin to work for random startups.
why didn’t I choose finance? Instead of jumping around ops roles with undefined tasks.
why didn’t I do an online coding course? Instead of studying data science for two years at 26 y/o.
this is not a pity party. I believe I’ve done difficult things in the last 5 years, taken risks that my peers would never take and had quite a few pinch me moments. i would just like recruiters to see the big pictures instead of focusing on badges and labels.
anyway, still looking.

Hackathons are blowing up in London (and beyond). I saw this anecdotally, then the search traffic analytics agreed.
It's because AI has done a few things:
1. Made software faster/cheaper to make
2. Broadened the type of person interested in making software
3. Made hosting hackathons easier, because you can do them faster
So we're seeing the supply (of hackathons/venues) AND demand (of participants) expanding at the same time.
Speaking to some of the young people at hackathons, in Ramen Space and beyond, it's increasingly how smart young people are socialising, learning, finding work, having fun.
But with hackathon discovery sites, I kept running into:
1. They're incomplete (e.g. not picking up some called 'buildathons' or 'hack nights')
2. They're a bit bloated, clunky or unfocused
3. I wasn't feeling the vibes UX wise
So on Saturday I hacked together londonhackathons.com to help me keep on top of them.
Complete with:
1. Thorough, expansive hackathon discovery for the next 90 days
2. Weekly newsletter to stay on top of stuff
3. Nothing else yet, let me know what you want 🤩
I’d love to see if one of @ElevenLabs voice models can actually fool a chilean person
