Bye bye San Francisco 👋 It was my first time in the USA, so here is what surprised me: - SF is like X IRL. Tons of billboards ads for Vercel, PostHog, and AI startups - You can bump into anyone and start a conversation. Ppl are very friendly - Food is mediocre imho - It’s expensive AF. $10k/mo is just above survival - The tech grind is contagious. Makes you wanna ship more, as Dominik Sobe ツ said. - Air quality is awesome (very low PM2.5) - You go from multibillion startup office to super poor area in 1 block (note to self: don’t follow Google Maps “busy area”) - The city is infested by self driving cars. It’s dystopian Thanks again for having us Stripe. It was awesome to meet my indie friends IRL

I made an app to turn web analytics into a Severance episode. Every page on your site is a department. /pricing is a department. /blog is a department. Your visitors are innies now. When they visit your site, they arrive through the elevator. When they navigate to another page, they walk to the next department. When they bounce, they walk out. It's called MACRODATA:

I made TinderMRR. Instead of people, you swipe on startups for sale. Swipe right to acquire. Swipe left to pass. All startups have verified revenue from Stripe, LemonSqueezy, etc. It's connected to my $1.2B database of verified startups, TrustMRR. Goal: Someone buys a $50k MRR SaaS because they swiped right on the toilet >

I tested my V02 max for the first time today: 🫀 57.4 ml/kg/min According to ChatGPT, that's the top 5–10% of men my age. The test was done in a lab using the Bruce protocol. Every 3 minutes, treadmill speed and incline increase: - stage 1: 4 km/h at 10% grade - stage 2: 5.5km/h at 12% - stage 3: 6.7 km/h at 14% - etc etc I passed out at the end of stage 5. It's just a horrible test because you're fighting inner demons to get a little farther. V02 max is a key biomarker in predicting longevity, so from now on, I'll focus my training on increasing that number.

I hate working on this startup... But Stripe disputes now cost $30, so I added a new rule to ByeDispute: 1. If a customer makes a successful payment 💳 2. BUT had recent payments blocked by Radar 🚫 3. Choose any to avoid a dispute ✅ If you're a startup founder with Stripe disputes, please let me know what would be helpful based on previous patterns.

I made an app to fix my terrible posture. It uses my MacBook Pro camera to watch me work. When AI detects that I’m sitting like a shrimp 🦐, it sends me a notification with a preview of my posture so I can reposition myself. Everything stays local. It works offline too. > And because apparently my brain only responds to fake rewards, I added XP: good posture makes my shrimp evolve (currently level 7).

I told JR Farr I make money off Stripe's 0.4% invoicing fee I told Jeff Weinstein one of my 24 Stripe accounts has a -$2K balance Yet they flew me to San Francisco and offered me a non-alcoholic Guinness. Stripe is one of the rare big companies that doesn’t enshitify and actually cares about its customers.

I've created a monster... My web analytics now scans 𝕏 for mentions of my startup. Whenever someone tweets a keyword I track, like “DataFast”, the post appears directly on top of my traffic and revenue charts. Boring analytics are dead 💀 (this tweet will literally show up on top of my own revenue chart)

AI is making software development easier than ever. One day, maybe all SaaS will provide only an API key, with no user interface, and your AI will create the interface within your OS. Maybe it's a crazy idea, but it sounds possible (and awesome), so I gave it a try: I shipped 18 new API endpoints for my web analytics SaaS DataFast ✨ All your website data is accessible programmatically: unique visitors, total revenue, pages visited, countries, etc... That way, you can vibe code an entire analytics dashboard with a 1 prompt without worrying about the complexity of the backend! If you build something on top of it, please DM me. I'd love to check it out.

I've created a monster... DataFast Realtime Map now shows the likelihood of a visitor making a purchase 🤑 The algorithm analyzes 10 metadata points (browser, country, referrer, etc.) from your previous purchase patterns to make predictions. 🥵 Warmer color = higher chance to become a customer 🥶 Cooler color = cold traffic... I also added a confidence score (not all segments have enough data) and an estimated value for this visitor (predicted conversion rate X average purchase for a similar segment). Your startup needs at least 1,000 visitors and 10 attributed payments to see the prediction data (the more data, the better the accuracy) Available now!

I built a full startup marketplace: 👋 Sellers: - Chat with buyers - Manage your listings - Verify with government ID 🛍️ Buyers: - Chat with sellers - Discover startups - Verify with government ID If you've listed your startup for sale on TrustMRR, here's how to see all the offers you've received: 1. Go to the /login page 2. Claim your startup(s) 3. View offers in the Chat tab If you're buying startups on TrustMRR, visit the /login page to view and manage all your offers. 🚨 Buyers and sellers with verified government IDs will receive a boost (more visibility for sellers, less chance of hitting the spam filter for buyers). The missing piece is Escrow (or a similar service) to facilitate asset transfer. I’m not familiar with this, so suggestions are welcome!
