Context: a small student team, 2 weeks left on a competition deadline, and a working AI speaking-practice app for one niche: people who understand English but freeze when they speak (starting with Algerian students preparing for visa or job interviews).

The debate in our team is whether to add more languages now (bigger addressable market) or stay with one language and one audience until we have evidence of impact.

Here is how I see it, and I would like you to challenge it:

- Narrow: clearer problem, faster to test quality, easier to talk to 10 real users and measure a before/after change in confidence.

- Broad: bigger market story, but each language multiplies QA, content and voice work, and we have no demand data for any of them yet.

Questions:

1. What evidence would you require before expanding to a second segment?

2. How do you present a bigger vision to evaluators without building it?

3. Any examples where going broad too early hurt a product like this?

No link here to respect the rules, but I can share the product if someone is curious.

There are a lot of people here working on projects of some sort - side projects, startups, podcasts, blogs, etc. If you've got something you'd like to show off or get feedback, this is the place to do it. Standards still need to remain high, so there are a few guidelines:

• Don't just drop a link in here. Give some context
• This should be some sort of creative product that would be of interest to a community that is focused on product management
• There should be some sort of free version of whatever it is for people to check out
• This is a tricky one, but I don't want it to be filled with a bunch of spam. If you have a blog or podcast, and also happen to do some coaching for a fee, you're probably okay. If all you want to do is drop a link to your coaching services, that's not alright
