258 users in 2 days with zero ads — here's exactly how we did it (and the real problem we're solving)
Students are lying to themselves.
They watch 6 hours of tutorials, feel productive, and actually retain almost nothing. I was one of them. Most of my friends were too. We'd finish a YouTube playlist and still not be able to build anything from scratch.
That's the problem we built Lumetrix Play to solve.
You paste a YouTube link or a course outline. Our engine converts it into a fully personalized, adaptive coding challenge path — with a built-in online compiler so you're actually writing code, not just watching someone else write it. The challenge sequence rewrites itself in real time based on how you're doing. No two users get the same path.
We launched 2 days ago. 258 users. No paid ads. No Product Hunt yet. No press.
Here's what actually worked:
→ We manually shared the link across WhatsApp college groups
→ I personally messaged people on LinkedIn and asked for honest feedback
→ The feedback loop was immediate — students got it instantly because they'd lived the problem
The thing that surprised me most: people didn't sign up because of the gamification or the XP system. They signed up because they were tired of feeling busy but not actually learning anything.
We're 18, bootstrapped, MSME registered, based in Chennai. Just getting started.
If you're a student who's ever finished a tutorial and immediately forgotten everything — I'd love for you to try it: https://lumetrixplay.sidhi.xyz
Happy to answer anything about the growth approach or the tech behind the adaptive engine.
And one more important thing brothers tell me whether this is worth working on ?
258 users in 2 days is a real signal. The problem you identified is genuine.
The thing to watch now: those 258 came from WhatsApp groups and communities you seeded manually. That's warm traffic from people who know you or felt obligated to help. The real test is what happens in week 2 and 3 when you stop manually sharing.
Two metrics that will tell you if this is worth pursuing:
If strangers return on their own and can't stop using it, that's your answer.
alright buddy let me try that
The tutorial-to-project gap is probably one of the biggest problems in programming education. I like that you're focusing on getting users to write code immediately instead of consuming more content. Definitely seems like a problem worth working on if users keep coming back after the initial curiosity.
THanks for ur response mannnn ... !!
Yes brother, this is worth working on.
The problem is very real. Many students finish tutorials but still cannot build anything from scratch. If Lumetrix Play can turn passive watching into real coding practice, that is a strong use case.
258 users in 2 days without ads is a good early signal. Now focus on retention: are students coming back, completing challenges, and improving?
Your best positioning is simple: “Stop watching tutorials. Start building.”
Keep going, but measure user retention and learning outcomes closely. That will tell you if this can become a serious product.
Yes brother sure . if possible refer ur buddies to use this platform
Feature requests from real users who are actually learning on the platform -- that's a good problem to have.
On the language requests: don't build all three at once. Figure out which one your current 10 learners most need based on what they're actually studying, not just what they asked for. Java is probably the fastest to add given how well-documented the tooling is; Rust is a longer project given its learning curve. Prioritize the language that gets the most learners past their first real project.
The 10 students using it including yourself is the most important number right now. Keep watching whether they come back.
sure budddy
The WhatsApp college groups angle is the interesting part. You found a channel where your exact ICP already trusts each other -- that's harder to replicate at scale but it's also proof you understand who you're building for better than most.
The thing you buried in the post: people signed up because they were tired of feeling busy rather than for the gamification. That's more useful signal than any survey. Most ed-tech bets on engagement mechanics. You found a shame gap -- finishing tutorials, retaining nothing -- that people won't say out loud until someone names it first.
On "is it worth working on": 258 users via DMs and WhatsApp in 2 days isn't viral but it's genuine pull. If 10 of those 258 come back without you nudging them a week from now, that tells you more than the signup number does.
Thanks mannn for ur reply ....lemme tell you what currently happeningg today...one girl form CIT demanding java and rust support , IIT graduate requested php ..my own college students asking for playground features whre they can code freelyy....and 10 students including myself are learning ion that platform nowww......if possible share this platform to maximum number of students you know to help them..WE DONT COLLECT EVEN ONE DOLLOR OR DISPLAY ADS . ITS COMPLETELY FREE
Proof that starting with your local community works. 258 users in just 2 days! Congrats on the amazing launch.
Thank you mannnnnn .. but local community alone is not enough right .... we need to expand further .... so do u have any suggestions for our expansions ?
258 users in 2 days through manual WhatsApp outreach is honestly a stronger signal than most polished Product Hunt launches — those are real people who felt the problem, not curiosity clicks. The fact that they signed up because they were "tired of feeling busy but not learning" tells you the core value prop landed, which is the hard part.
Is it worth working on? I'd say the better question right now is: what does day 7 retention look like? Early signups from your personal network are warm — the real test is whether students come back after that first session without you nudging them. If they do, you have something. If they don't, that's your next thing to solve before scaling acquisition. Either way, keep going.
yeah sure man ... what advice you would give me to make this product undenieable
One thing: make the value visible. Most apps do meaningful things in the background that users never notice. In LifePilot we realized the coach was adapting plans, lightening workloads, breaking down hard tasks — but silently. The moment we started surfacing exactly what changed and why, the product felt completely different. If your product is working for users, make sure they know it's working.
i dont know which word i must use here to thank you but this is the most valuable feedback i got so far.....u r right we dont show the user whats happening in the background where we are using advanced tech for thier benefitsss..lemme fix that
I'd be careful with one thing.
The interesting question may not be whether students like the product.
It may be what kind of success would actually deserve confidence that this is worth building long term.
Those sound similar, but they can lead to very different decisions from the same early traction.
I wouldn't make that call casually from the current signals.
i can understand man
