A lot of founders think they need a technical cofounder when what they actually need is one engineer who will tell them no. The value isn't the code. It's someone with the standing to say "that will take four months and here's why," and be believed.

@kelvinbuildss Currently building an AI tool to debate business decisions. Let’s connect?

Hey founders ! Looking to connect with people building in: 🍽️ SaaS 🚀 Tech 📲 Automation 🧠 AI tools 📱 Product Development 🔥 Web APP 💻 Devs Drop what you're working during this week

@billainsahu Let’s connect. Working on an AI platform called Edge Arena.

Hey people ! Looking to connect with people building in: 🚀 Tech 🧠 AI tools 📷 Personal brand 📱web tools Drop what you're working on

@farhanchyyy Always willing to connect with other founders. Currently building in both AI and blockchain spaces.

@souvikdeb26 The biggest advantage of learning from scratch isn’t syntax anymore it’s developing the mental model. Once you understand why and how code works AI can then expedite your work but without knowing the fundamentals AI will produce code that isn’t maintainable

Genuine question: Does it still make sense to learn coding from scratch in 2026? And please don’t give me the “people who use AI will replace people who don’t” answer. If someone were starting from zero today, would you still recommend learning to code from scratch?

AI didn't remove the need for architecture. It raised the stakes on it. When generating code is cheap, the cost of a bad boundary compounds much faster because you'll have ten thousand lines sitting on top of it before anyone notices the shape was wrong.

Founders: what did you outsource that you should have kept in-house?

@surim0n Toronto based founder here. Would love an invite too.

i didn’t expect to receive this kind of response dm’s will start coming out in the next few days after i figure out the best way to message all of you if you have an anon account, it makes it harder

I build on-chain side projects and I'll say the quiet part: most blockchain projects are a database with a much worse developer experience and a much better narrative. The ones that work are the ones where the thing being decentralized is the whole point, not a feature you bolted on for the deck.

What's a piece of tech debt you've made peace with and will never fix? Genuinely think this is a senior skill and nobody talks about it.

The painful part of using AI for coding: It allowed the junior engineers to be more productive but made the senior engineer’s work much more difficult. Evaluating large amounts of code which is very sure about itself and seems plausible is a different skill from writing it and most teams haven't staffed for this shift yet

Any team adopting microservices to go faster runs into the same problem after six months. The problem wasn’t ever the monolith itself. There was no agreement on what people owned. Now you get the exact same debate except now it’s across networks and with retries.

Signs your architecture review is theater: - the decision was made before the meeting - the doc is written to justify not to explore - nobody names a tradeoff they're actually unhappy about - the only real debate is about naming - someone says we can revisit this later Nobody revisits later.

@coryalthoff Proprietary data. Everyone can copy distribution methods but in some niches without data you can’t compete at all

Which will matter more in 2030: proprietary data or distribution?

If AI coding is just becoming infrastructure, what's the next application layer worth betting on?

We love dunking on the 'idea guy,' but picking the right thing to build probably matters more than building it well. I've made some really clean, polished stuff that nobody wanted. Turns out that doesn't count for much 😅

@BeavanAI @X Oh nice. A platform where multi agents compete to decide business decisions. Its called Edge Arena. How about yourself?

@jaymansfield @X Hey Jason. Fellow Canadian all my families from Toronto, but I’ve been living in Texas for 20 years now what are you currently working on now?

🚀 Hey @X algorithm — let's build something incredible. I'm looking to connect with people passionate about: ⚡ Backend Development ⚡ Full-Stack Engineering ⚡ DevOps & Cloud ⚡ AI / Machine Learning ⚡ Data Science ⚡ UI/UX Design ⚡ Python ⚡ JavaScript ⚡ Java ⚡ SaaS ⚡ Startups & Founders ⚡ Marketing & Growth ⚡ DSA ⚡ Vibe Coding If you're building, learning, hiring, investing, or just obsessed with tech... 👇 Drop a "Hi", tell me what you're working on, and follow. I'll personally reply to everyone, help make introductions, and connect you with the right people in my network whenever I can. Let's build an incredible community where everyone grows together. #BuildInPublic #AI #Programming #Python #JavaScript #DevOps #MachineLearning #DataScience #Startups #SaaS #100DaysOfCode #TechTwitter #Coding #Networking

The office I pictured: standing desk, plants, deep focus. The office I have: a laptop and a baby monitor at 92% volume 😅

@coryalthoff Start planning the next one 🤣

Your startup just exited for life-changing money. What's the first thing you do?
