[Wild stat 🤯] ChatGPT now drives almost as many monthly users as Instagram to the order of ~5B users - creeping up to similar depth of engagement (7.5 mins per session vs IG's 8.5 mins) One's a "drier" Q&A engine and the other a video-rich social app Data: Aug 25'
[Underrated tech find: Back to the future] $19 USB-C "wired" Apple Earpods. USB-C now transmits "lossless audio" (24-bit/48 kHz) that sounds better than compressed audio on AirPods Pro 2 on bluetooth.
My time at Postmates taught me the 3 biggest hurdles to food delivery app growth: 1. Selection 2. Availability 3. Price In Part 3 of Data Science playbook dpal.substack.com/p/data-science… -I break down how we boosted checkout conversion for high intent users
Defaults matter. Storing chat history and allowing the model to train on data can be toggled "off" on frontier AI apps. This is separate from the concept of "memory" which still persists outside chat history.
Dropped a new substack on Product Analytics — Part 1 captures Instagram and Zynga open.substack.com/pub/dpal/p/dat… Part 2 captures TikTok open.substack.com/pub/dpal/p/dat…
[Wild stat] Half the world’s VC funding in Q1 2025 flows through the Bay Area, skewing more this year - $55B (~49% of Global VC dollars up from 32%) No city close - NYC (7%), Beijing(6.3%), London(4.7%),Bangalore (3.2%) Despite more tech hubs, money moves where exits are!
After years heads-down at TikTok, Instagram, Postmates, Zynga & EA - I'm writing my learnings from each of them in a substack series. "Product analytics" Data Science lessons you won’t find in slides. Part 1 here -> dpal.substack.com/p/data-science…
Back in the day, during Zynga onboarding, the team’s first assignment was simple: Play FarmVille until I hit level 20. That deep dive was formative in uncovering bugs and building empathy for the product you can’t find on a dashboard. Solutions begin in "experience"
Hard to think of an app that exemplifies "English is the modern coding language" than @cursor_ai - Buttery smooth - Shockingly few hallucinations - actually understands prompts
[My favorite AI use case: Voice] While image creation and agent-based use cases are more spoken about, find "AI voice" most useful - Lower latency than typing back and forth for response - Tonality captured - Use cases: Soundboard for ideation, mock interviews, etc
For all the innovation in AI, I still wonder how Google Sheets hasn't added a custom "K" and "M" formatter to format 170,182 as 170K or 0.17M Should at least be a suggestion on "Custom Number format"
There are just two kinds of people — 1. People who think its urgent enough 2. People who don’t think its urgent enough Be all.
For sometime now, ai.com was how I would access ChatGPT on browser. It now redirects to deepseek.
1. Apple branded iPhone 16 around “Apple Intelligence” 2. Did not release Apple Intelligence out of the box 3. Expected release with 18.1 (Oct 28) 4. In 18.1, find it in settings (easter egg) and join Waitlist Prime usage of the “scarcity principle” with a strong brand.
[Canadians are nice people: Testimonial 2273] In a coffee shop in Vancouver, saw the Barista taking paper towels and cleaning the toilet every 2 hours or so. Haven't walked into a Starbucks or coffee shop here with a clogged toilet here, feeling a difference.
Schedule send” (now rolled out across Gmail, iMessage, WhatsApp) might be a game changer for handling communication expectations
Pretty big on working for products that you use as a consumer. Makes work fun.
