Applications for the Fall 2026 @southparkcommons.bsky.social Founder Fellowship are now open. Five years ago, I almost didn't apply. Looking back, it was one of the most consequential decisions of my career.

Two conversations have stayed with me since Vercel Ship NYC last week so I wrote up a few reflections, with post title inspired by the conference wall art: "You Can Just Ship Things." blog.nseldeib.com/p/you-can-ju...

As distance between an idea and a working prototype has gotten dramatically smaller, I've found myself building more. More thoughts on this: blog.nseldeib.com/p/what-if-cr...

Last weekend I ran my first 24K trail race. Then, because my race tracking failed and I’m apparently very stubborn, I ran another half marathon the next morning for NYRR virtual race credit… then climbed the Manitou Incline 😅 Now that my legs have recovered, I’ve been reflecting on stubbornness.

At CodeYam, we’re lucky to work with an incredibly talented product designer, Dani, who’s been pushing the limits of what AI can (and can’t) do in software product design. blog.codeyam.com/p/the-two-xs...

As a second-time attendee at the Female Founders Retreat, I had a surprisingly hard time putting this year’s experience into words. I wrote up my thoughts on The Magic of Attempting Hard Things here: blog.nseldeib.com/p/the-magic-...

Recently, I’ve been reflecting on something I think is one of my superpowers: networking. Ironically, I hate the word “networking.” It evokes transactional interactions, performative conversations, people aggressively collecting LinkedIn connections or pitching each other. That’s not what I mean.

🚨 3 minutes and 30 seconds. One new category. Two live demos. No pressure, right? 😅 Last week I presented CodeYam at the Vercel AI Accelerator Demo Day at Okta HQ in San Francisco.

What might building software look like in the Star Trek universe? Our team at CodeYam, especially my co-founder @jaredcosulich.bsky.social, has a bit of a superpower: blending imagination (often influenced by science fiction, fantasy, and history) with deep, pragmatic problem solving.

We need a phrase, akin to the "uncanny valley" to describe a technological landscape that is far more complex and nuanced than we expected. Self-driving cars are insane! - but they can't handle weather. AI is insane! - but it still struggles to remember things you talked about 10 minutes ago.

After our Product Hunt launch this week, a few founder friends reached out asking if we had any learnings or best practices to share. I wrote up an honest (and somewhat long, sorry) reflection on our recent launches to Show HN and Product Hunt, including the prep work and what actually happened.

Over the past few months we’ve been using Claude Code heavily for software development. One issue we kept running into was memory. Claude Code would repeat the same mistakes and our claude [dot] md files would slowly get stale.

Are you on Product Hunt? After years of lurking, I’m finally launching my first product there tomorrow. If you’re on Product Hunt, feel free to follow me at “nseldeib” and I’ll happily return the favor. Tomorrow morning we’re launching CodeYam CLI & Memory for Claude Code.

Made my first Show HN post today. Woke up early with the nervous/excited butterflies that come with shipping something new. Posted it… and within minutes watched launch after launch push it down the feed. Such is life on Hacker News. Still really proud of what we built.

Lost an AirTag weeks ago. Find My said it was at my climbing gym but I had no clue where. Asked lost & found yesterday mostly on a whim. Someone suggested pinging it. Immediate chirping from the bin. Same day I recovered sunglasses from a ski jacket pocket I’d already washed.

Preface: I’m okay. Had a small mountain (mis)adventure this weekend that felt very startup-adjacent.

One thing I keep relearning as a founder is that communicating a complex product can feel almost as hard as building it. We have been using AI not just to write code, but to pressure test how we explain CodeYam. Our product designer Dani wrote more about this. Link in the comments.

I often hear some version of: “Why can’t AI just do X?” Where X is a software development task like fixing a bug, writing a test, or making a clean code change. Usually the answer is simple: the task is more complex than it looks, for both the human responsible and the AI doing the work.

"APPROVED - Ship It!" 🚀 Set myself a challenge: rebuild the @codeyam.bsky.social website from Figma designs using AI coding agents. Claude Code CLI acted as: → Programming pair → PR reviewer → Pseudo-CTO

AI workflows aren’t just for prototypes. I rebuilt parts of the @codeyam.bsky.social website using an agentic coding workflow...and it is almost production-ready. Curious: would you trust AI-generated code in your own projects if humans reviewed it first? Full thoughts below👇

We ran an experiment: can AI tools build real, functional software from a natural language prompt? The result: a deep dive across 7 “vibe coding” tools, from v0 to Lovable to Figma Make. All built something, but not always what we expected. 👉 Full write-up here → blog.codeyam.com/p/creating-s...

Been diving into how AI is reshaping software development. Not just faster code, but better feedback loops, more intuitive tooling, and sometimes strange bugs. Wrote a piece on what I’ve been learning through CS50, vibe coding tools, and building in the in-between. open.substack.com/pub/nseldeib...

Just published a practical guide to recruiting quality user research participants when you're bootstrapping the process 🔍 At CodeYam, we've learned that talking to the wrong people = useless data, no matter how good your questions are. Read on: nseldeib.substack.com/p/finding-re...

If you're a founder friend, you know that for years I've been obsessed with leveraging qualitative user research to create faster feedback loops to improve learning velocity and iteration, especially in the earliest stages. 👇 Introducing a new series on this: nseldeib.substack.com/p/build-fast...

Listening to Tubes: A Journey to the Center of the Internet by Andrew Blum and am struck by how much of the internet's history (and present!) is in suburban Virginia, where I grew up. As a kid, I had no idea. Is this taught now? I would've loved to learn about the internet's creation and evolution.

Hey #startup folks — I’m Nadia, CEO & co-founder of CodeYam. We’re building something new for developers and running 1:1 usability interviews on April 23 & 25 (and beyond). Sign up: forms.gle/rjUe3YzKxjkf...

Will folks be at the @dora.dev meetup at Google Cloud Next today? Hoping to join and meet some familiar-from-Meets faces!

As a founder wrestling with the speed v. quality tradeoff, I'm fascinated by AI tools promising both. Our product designer tested four AI-native tools to redesign our @codeyam.bsky.social site. The result: impressive speed, but real limitations. Read her findings: blog.codeyam.com/p/testing-th...

No matter how good AI becomes, one fundamental challenge persists: communication. Despite significant AI progress, effectively communicating with LLMs remains a significant and under-appreciated problem that will hold back AI's value. blog.codeyam.com/p/ai-cant-re...

This is crazy, egregious, beyond the pale. Musk has legitimate influence and power and is pushing to jail a political opponent. A prominent senator. This is as anti-democratic as it gets.

Spent two days with the Boldstart community in Miami talking AI-native software development. We're not just changing what we build, but HOW we build. Everyone's using AI tools, DX is evolving rapidly, and we're seeing early signs of a B2A (business-to-agent) future emerging.

Did I always know I wanted to become a founder? I get asked this question all the time. Today, I shared the journey that led me from to the @southparkcommons.bsky.social Founder Fellowship and creating CodeYam with my co-founder Jared. Read it here: nseldeib.substack.com/p/founder-fa...

Morning thoughts on successful founder-market fit and the roles played by effort, ability, and luck. These are distinct yet interconnected factors that you can influence but cannot perfectly control as a founder.

Isolation and abstraction are two useful techniques that humans use to navigate complexity and large amounts of inputs. Historically, we've applied these concepts to great effect when developing software. But what about when developing software with AI?

New product feature shipped! Our goal with CodeYam is to make it easier to understand, test, and deliver valuable software changes. To do that, you have to tame software’s complexity. This demo shows how we try to do that for CodeYam itself.

A couple of months ago, I attended a @github.com Women in Tech dinner. Each attendee left with an action item. Mine was to be more transparent about how I became a founder and what I've learned (and unlearned!) along my non-linear journey. Read more: nseldeib.substack.com/p/founder-fa...

Yesterday, I got a text from a founder friend just reminding me that they believe in and support me. This got me thinking: I sometimes forget to express appreciation and celebrate what I love about the people around me enough.

Earlier I was looking for great product-oriented demos of software products. Found a 16 year old "DropBox" demo @dropboxofficial.bsky.social that certainly fit the criteria. Not sure if it was successful or not at the time, but it's incredibly product-centric. www.youtube.com/watch?v=7QmC...

As an experiment and in that spirit of shipping something imperfect-yet-useful over something perfect, I published a blog post today: nseldeib.substack.com/p/taming-sof...

Feels appropriate to go literal for the first post here. Hello 🦋!
