Overtone looks like a great way to explore MusicBrainz data—the subgraph expansion is really slick. Since you mentioned you're looking for feedback, I ran your landing page through a conversion tool I'm working on. It gives a prioritized plan on how to make the value prop even clearer for new users. Might be helpful as you move toward adding the playlist features! https://websiteroasters.com/ Let me know if it help you :)

This is a fascinating breakdown of EBMs. Regarding your 'ship vs. tune' dilemma: one of the biggest risks of shipping with a 34% FP rate isn't the tech itself, but how it's messaged on the landing page. If users expect a perfect firewall and get blocked on benign code, they’ll churn.

I actually built a tool called AI Website Roast that helps founders in this exact 'stuck' phase. It analyzes your landing page to see if your value prop and 'Beta constraints' are clear enough to prevent that frustration you're worried about. Happy to run a roast on ebmsovereign.com for you to help make sure your first impressions don't get hit by the 'weak' categories you mentioned.

If you can check it out and give me some feedback as well if helps https://websiteroasters.com/

This is a clever script! Regarding your question on heuristics: technical errors (SSL/Speed) are good, but I've found conversion friction is a much stronger proxy for 'willingness to pay.' Business owners care less about a missing favicon and more about 'why users aren't clicking the Call button.'

I actually built something that automates the 'conversion audit' side of this. It analyzes the page and generates a prioritized improvement plan. It might be a great 'high-value' attachment to those cold emails to prove you've done deeper thinking than a standard bot. Happy to let you run a few of your Las Vegas leads through it to see if the pitch resonates better!

If you want you could run it and if possible just give me the feedback after or if you need any help with that. :) https://websiteroasters.com/

Congrats on the launch, Kristof! Social proof is definitely a huge lever for conversion. I took a quick look at your page and have a few thoughts on how you could sharpen the copy to really drive home that 'verified proof' value prop. If you're open to it, I'd love to run a full AI roast on your landing page and send over a prioritized list of conversion fixes? Might help you squeeze a bit more ROI out of your launch traffic.

You can try it for free. And if you need more help with that just contact me :)

This is a cool set of games! Since you're looking for feedback to see if people enjoy the idea, I ran your landing page through an AI tool I built that 'roasts' websites for conversion and clarity. It might help you spot why people might bounce before trying the daily games. Would you be open to seeing the report? It could help you get more of those free account signups you mentioned.

https://websiteroasters.com/ just check it out :) and if you also think you need help on do it just tell me we can talk!

vansbel — Sun, 08 Mar 2026 19:27:19 +0000

This is a fantastic resource! I love the map-first approach for niche discovery. Since you mentioned you're looking for feedback on how to make it more useful, I actually ran Yumo.to through an AI landing page 'roast' to see if there were any clarity or conversion gaps for first-time visitors.

One quick takeaway: visitors might initially miss the 'tattoo-friendly' filter, which is a huge USP for international travelers. Helping that stand out could really drive engagement. Happy to share the full prioritized improvement plan if you're interested!

New comment by vansbel in "Ask HN: What early signal convinced you to pivot?"

vansbel — Sun, 08 Mar 2026 19:22:24 +0000

This is a great question. Often, it's hard to tell if the product is wrong or if you're just failing to explain the value clearly on your landing page. If you're worried about 'bad conversion' being the noise, I actually built a tool (AI Website Roast) that gives a brutal/honest look at exactly where a landing page is losing people. Might help you figure out if you need a pivot or just better positioning. Happy to run it on your URL if you want a second set of eyes? You can also put it in and try it.
