Marcelo Calbucci @calbucci.com · 26/09/2026Officially switching from RunKeeper to Strava to record my runs. I've been with RunKeeper for 15+ years, but the lack of an API and an MCP sealed the deal. 000
Marcelo Calbucci @calbucci.com · 24/09/2026I built my personal fitness display, a website to manage my training plan, and an MCP to let Claude control everything and adjust my plan according to my races, weather, etc. I believe that in the next decade we'll see a renaissance for the arts, science, technology, industry, and humanity. 300
Marcelo Calbucci @calbucci.com · 23/09/2026At this point, I don't want better frontier models. I want faster (!!!), cheaper, and less-error prone models. 000
Marcelo Calbucci @calbucci.com · 17/09/2026I'm looking forward to an AI agent that can organize and consolidate the decades of notes and files we have on OneNote, Notion, Google Docs, Dropbox, OneDrive, Notes App, and everywhere else. To answer your question, no, I won't use Muse, OpenAI, Claude, or Gemini. It has to be a local LLM. 420
Marcelo Calbucci @calbucci.com · 14/09/2026People are handing full access to their emails, documents, and calendars to "unknown" AI agent startups and to corporations with a checkered past of privacy violations. 040
Marcelo Calbucci @calbucci.com · 03/09/2026I'm old enough to remember when GPT-3.5 launched, and people said when GPT-5 launches the entire world is cooked. The jobs would be gone, society would collapse, Skynet would be here…Now LLMs struggle to have two-9s of availability. 010
Marcelo Calbucci @calbucci.com · 03/09/2026I'm going to make many tech solopreneurs upset when I say this, but you don't need Linear, branches, PRs, CI/CD, or staging until your product has meaningful traction. 021
Marcelo Calbucci @calbucci.com · 02/09/2026Folks, I'm not sure Amazon offers the best prices. I bought a product directly from the manufacturer, paid $8 for shipping, and the total came out to $35. On Amazon, with free Prime shipping, it was $47.49. 040

Marcelo Calbucci @calbucci.com · 19/07/2026Haaland, Vozinha, and Bellingham are the super heroes of this World Cup. It's not even a contest. 030
Marcelo Calbucci @calbucci.com · 14/07/2026BREAKING: Company led by a leader with low morals does a bad thing. 020
Marcelo Calbucci @calbucci.com · 10/07/2026With Claude Code, you are on the edge of your seat. You don't know if it'll crash, the API will error out, if you hit the usage limit for the period, or if it'll build an amazing feature. 270
Marcelo Calbucci @calbucci.com · 30/06/2026This is the first World Cup that you learn about a team scoring in the group chat before you see it on TV. 010
Marcelo Calbucci @calbucci.com · 25/06/2026LinkedIn Games is what happens when your strategy gets disconnected from your customer. Games -> Attention -> Ads -> Revenue. How does this align with their vision of "creating economic opportunity for every member of the global workforce"? This is what Eric Ries calls "corruption" in his new book. 110
Marcelo Calbucci @calbucci.com · 17/06/2026This is the first World Cup with mass TikTok use, prediction markets, and AI. 100

Marcelo Calbucci @calbucci.com · 27/04/2026If you work at Microsoft, May 7 is a big day. I worked there for 7 years. Built Startup Day for people sitting where you are now. Stay or go? Found or join? 16 founders sharing what actually worked. Startup isn't for everyone. Is it for you? May 15. Seattle. Prices go up Friday. Link below. 170
Marcelo Calbucci @calbucci.com · 23/04/2026I worked for 2 years in Benefits/HRTech, and 5 years in HealthTech. My superpower was to be an idiot in understanding insurance, benefits, and healthcare. h/t @morningbrew.bsky.social 120
Marcelo Calbucci @calbucci.com · 22/04/2026UNBREAKING: PRDs are not dead. It has a new shape, but still is a PRD. 020
Marcelo Calbucci @calbucci.com · 21/04/2026If you take the blip from the pandemic, Seattle has had the lowest # of investment deals in a decade (since 2016 Q4). The situation is worse than it appears because the total number of deals in the US has grown 40% since 2016. I have several theories, but I want to hear what you think is going on. 110
Marcelo Calbucci @calbucci.com · 21/04/2026Software engineers, PMs, designers, and CS / ML / MBA students: We're doing a Startup Fair @ Startup Day 2026. Builders from Clarify, Yoodli, Clearly AI, Predictable Machines, and more will talk product, tech, and their roles. No recruiters. May 15. Free 👉 seattleflow.org/fair 1201
Marcelo Calbucci @calbucci.com · 21/04/2026The Startup Day 2026 speaker lineup is live. 16 founders. 30+ startups built between them. Over $1B raised. Products used by billions. Seattle, May 15. Here's who's on stage. 👇 3161
Marcelo Calbucci @calbucci.com · 12/04/2026I don’t think there’s ever been a time that so clearly separates people with a growth mindset vs. fixed mindset. 240
Marcelo Calbucci @calbucci.com · 09/04/2026The current conversations about AI remind me of when we first controlled fire, 400,000 years ago. “Do we really understand fire?” “Will fire take our jobs?” “Can fire be trusted? What if it burns us?” “What if fire is just hype?” 121
Marcelo Calbucci @calbucci.com · 07/04/2026In 2010/2011, I printed a book called the Startup Guide. A directory of vendors and service providers for anyone building a startup in Seattle. Today we're launching the Startup Kit. Same idea, different format. A directory to help founders find the resources they need to build+grow their startups. 130
Marcelo Calbucci @calbucci.com · 06/04/20266,000+ tech layoffs in Seattle. Amazon, Microsoft, Oracle, Meta. You don't need permission to start a company. You don't need all the answers either. You need to learn from founders who've done it recently. That's why I'm putting together @seattleflow.org Startup Day! 4143
Marcelo Calbucci @calbucci.com · 06/04/2026The only reason Claude Code doesn't cost $2,000/month on the Max plan is Codex. 130
Marcelo Calbucci @calbucci.com · 04/04/2026Even if doctors don't adopt AI, medicine has changed forever already. Patients are more empowered than ever before by using AI to analyze labs and scans, to help them better describe symptoms, by challenging diagnostics, and to think about treatments that are right for them. 120
Marcelo Calbucci @calbucci.com · 02/04/2026AI feels like Vibranium. We are scratching the surface of what this new thing can do. 120
Marcelo Calbucci @calbucci.com · 01/04/2026Having multiple VS Code windows is the new having multiple tabs open. 130
Marcelo Calbucci @calbucci.com · 30/03/2026Shortcut to building a successful business: find a problem where you already know the market is there. Patrick Thompson built Clarify by skipping problem validation and front-loading business model validation instead. Hear Patrick + other founders at seattleflow.org/startupday 030
Marcelo Calbucci @calbucci.com · 27/03/2026Walmart with a P/E of 45 and Microsoft with a P/E of 22 were not on my bingo card for 2026. 030
Marcelo Calbucci @calbucci.com · 26/03/2026I've noticed a new trend on major products: bugs! Lots of bugs. I'm not saying it's LLM coding, but it feels to me that companies are struggling with the new software development lifecycle. 340

Marcelo Calbucci @calbucci.com · 23/03/2026There is a fine line between hallucination and vision. Ian Wong (Summation CEO, and Opendoor co-founder) got 5 companies to say “yes” before he wrote a single line of code. He's speaking at @seattleflow.org Startup Day 2026 on May 15 in Seattle. seattleflow.org/startupday 130

Marcelo Calbucci @calbucci.com · 17/03/2026Claude really needs a family plan. I'd be happy to pay for the four of us. Right now, I can't share a project with my wife or children. 111
