Products

ShipDuel

A faster, funnier way to find good products: two shipped products from the same category go head to head and you pick the one you'd ship. Daily and weekly boards, Elo ratings, a permanent page for every matchup, and a forum to argue in.

Ultraspeed

Paste a URL. In about 15 seconds your inbox names the three things making your site slow - not a 0-100 score, not your host.

Urbio

Manage properties, client offers, and responses in one workspace.

Validate before you build.

That’s the cheapest feature you’ll ever ship. Most products don’t fail because the code was bad. They fail because nobody needed them enough to pay or switch. Building first feels like progress. It isn’t. Talk to people who have the problem now. Ask what they already do instead. Then test with a landing page, waitlist, fake door button, or a manual version you deliver by hand. Likes are not validation. “Cool idea” is not validation. The only signal that counts is someone giving you time, money, or a meeting. Don’t start the real build until you can say: these people have this problem, they already try to solve it, and they took an action when I offered a solution. Then build the smallest thing that keeps that promise. Validate first. Build second. It will save you months and a lot of money.

Should I build this, or is it a vitamin?

Idea: I ask ChatGPT/Perplexity the questions your buyers ask ("best X for Y", "alternatives to Z"), show you who gets recommended instead of you and which sources the AI cites, then get you into those answers and prove it moved. Tracking tools exist (Semrush, Peekaboo, 20+ more). None get you into the answer. Would you pay for the outcome, not the dashboard? Vote below. Want a real data point? Drop your URL + main competitor in the comments, I'll run 5 buyer questions and post your result. Free, no signup.
