Now, without further ado...

Submissions are locked; here's what that means for you
That's a wrap on submissions for H0: Hack the Zero Stack. If you submitted — genuinely, nice work. Building a full-stack app on a deadline while holding down a job, a life, and probably a few too many browser tabs is no small thing.
What "submissions locked" actually means
As of the deadline yesterday, your submission was locked — and that's actually a good thing. It means everyone is on equal footing from here. No edits to your Devpost submission — not your video, not your Vercel project, not your links. You did the work. It's in. Let it breathe.

"Access must be provided to an Entrant's working Project for judging and testing by providing a link to a website, functioning demo, or a test build. If Entrant's website is private, Entrant must include login credentials in its testing instructions. The Entrant must make the Project available…

What judges actually want to see 👀 + Devpost Build Session
Hi there,
Judging kicks off June 30. Before you record your video or write your project description, let's talk about what actually makes a submission score well.
The judges are AWS Database experts. They know this stack. They will notice when you genuinely thought about your data model vs. when you just wired up a database to check a box.
What they're scoring you on
-
🔧 Technical Implementation — Is your database integration thoughtful? Real engineering decisions, not just "it connects."
-
🎨 Design — Does the frontend feel coherent with the backend? Full-stack thinking, not just a pretty UI.

Your demo video is doing more work than you think 🎬
Hey —
A lot of people treat the demo video like an afterthought. Those people lose.
Your video is often the first thing judges review — and for this hackathon, it has to do a lot in under three minutes: introduce the problem, show the app working, and make your database choice look intentional. Here's how to pull that off.
⏱️ The structure that works
You have less than three minutes. Use them like this:
1. The problem — ~20 seconds 🎯 Who is this for? What pain does it solve? One sentence. Don't spend thirty seconds on your company…

Stop. Breathe. Now let's build something great 🛠️
Hey builder —
You registered. You've got a deadline. And if you haven't gotten your credits yet — head to the Resources tab on the hackathon page to request your AWS and v0 credits while supplies last (you'll need a Track and an idea, but it's okay if you change your mind later!)
Now, let's talk about what actually matters this week: making a plan.
The difference between a great submission and a "welp, I ran out of time" submission usually comes down to one thing — the first hour. Not the last hour. The first.
Here's how…
