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 ?
Hey man, thank you so much for building this.
Guys, trust me — this is going to become something big. There's no doubt about that. This 18-year-old is cooking up something truly special.
Let's all do our part to help him out.
And hey kid, I'll do my best to bring this to the attention of as many people as I can, and I believe others will too.
The reason is simple: you're solving a genuinely important problem. So many people spend hours learning yet struggle to actually master what they've studied. You've recognized that problem and built something meaningful to address it.
Most importantly, you had the courage to build it without worrying about whether you might fail.
Keep going. We're rooting for you, and we won't let you lose without a fight.
Thank you. Messages like this mean more to me than you can imagine.
Lumetrix Play started from a frustration I personally experienced. I spent countless hours learning, watching videos, and completing tutorials, yet when it came time to build something on my own, I realized I hadn't truly mastered what I had invested my time in.
That's the problem we're trying to solve.
We're not trying to create another platform that helps people consume more content. We're trying to help people master what they learn.
The product is still young, and there's a long road ahead, but every piece of feedback, every bug report, every suggestion, and every user who gives the platform a chance helps us improve it.
If you genuinely believe in what we're building, the best way to help is simple: use it, challenge it, give honest feedback, and share it with someone who might benefit from it. Word of mouth is what helps small projects like ours survive and grow.
Thank you for believing in us. We'll keep building.
Your project and results are impressive; the fact that you've generated traffic through LinkedIn makes me want to promote my product through it as well.
Yeah great way to do that man . i dont know whether im in a postition to tell this .. when posting on linkedin have some people on your side to interact with the posts like comment , like , repost ...the algorithm loves this so much....and i have one more tip when reading posts across linkedin stop and wait a sec and see what they are saying ..if thats relevant to your product..then you can use that comment box to make big moves
258 users in 2 days with zero ads is a strong signal - especially because you can trace exactly where they came from. That traceability matters more than the number at this stage.
The insight about why people actually signed up is the most interesting part of your post. "Tired of feeling busy but not actually learning" is a much sharper problem statement than "tutorials don't work" - it's emotional, not just functional. If that's not already your headline, it probably should be.
One question worth sitting with: what does retention look like at day 7? The WhatsApp/LinkedIn launch gives you a warm audience who wanted to support you. The harder signal is whether strangers who found it cold come back and finish a challenge path. That's where the adaptive engine either proves itself or needs work.
Worth working on? The problem is real and the early traction is genuine. Keep going.
Alright brother lemme update the day 7 results soon
"Busy but not actually learning" is so real, I've lost whole weekends to tutorial playlists. 258 in 2 days at 18 is no joke, keep going.
alright brother . Thanks for your support
Congrats on the launch, Arshad! The immediate traction is impressive for an 18-year-old bootstrapped team. The fact that people signed up because they were "tired of feeling busy but not learning anything" is your core value proposition. Double down on that copy. One thing to watch out for with an "adaptive coding challenge path" is the accuracy of the LLM/engine generation. If the real-time generated challenges become too hard or too easy too quickly, students will drop off out of frustration. How are you handling the accuracy of the automated compiler grading to ensure students don't get stuck on false negatives? This is definitely worth pursuing if you can nail the path progression.
I'll give a try... But all that purple colors hurt my eyes 😅
Ha haaa... we deigned that way cz we got so much inspired by solo levelling . in solo levelling the hero levels himselves like wise users can level up thier skills here . And lemme tell you the next secret update which may not be a secret anymore "We R planning to provide pluggable Themes " so stick with us ...whats your favorite colour gentleman and by the whats ur username on the platfrom
258 users in 2 days with zero ads — that’s real.
Ran your landing page while reading. You named the exact problem in your post: “Students watch 6 hours of tutorials, feel productive, and actually retain almost nothing.” That’s specific and painful.
It’s not in your H1.
“Learn to Code. PLAY TO WIN.” is what every coding platform promises — Codecademy, freeCodeCamp, LeetCode, all of them. The thing that makes Lumetrix different — the tutorial-fatigue problem you actually solve — is invisible above the fold.
One swap:
Before: “Learn to Code. PLAY TO WIN.”
After: “Stop watching 6-hour tutorials. Build what you actually want — in days.”
Does this match the gap you’re seeing — people get it when you explain it, but the page doesn’t land it first? https://outboundautonomy.com/fix-sprint?ref=fixsprint-lumetrixplay
Amazing catch my frd !!! .. lemme fix that and update you about that ..and by the way why stopped at the landing page itself bro ??its unfair ..tell me what stopped you ?
Because the landing page is where the 259th user makes their call — without the WhatsApp context or a personal DM behind it. Your first 258 came through warm channels where people already trusted you. Cold visitors get 10 seconds with the page before they bounce.
The words that convert are already in your IH post, just not on the page yet. Gaps #2 and #3 done the same way — specific copy, paste-ready, 48h: https://outboundautonomy.com/fix-sprint?ref=fixsprint-lumetrixplay · $49 flat.
yeah sure man..lemme focus on fixing that landing page noww...i feel like it has very few conversion potential
The real signal here isn't the 258, it's WHY they signed up: 'tired of feeling busy but not learning'. You found the pain, not just a feature. That's worth working on. The manual distribution (WhatsApp groups + DMs) is also the honest lesson most people skip - it doesn't scale, but at 2 days in it's exactly right, because it tells you if the pain is real before you spend on ads. My only worry for you: retention. Lots of students will try a learning tool once. The question that decides if this is a business isn't signups, it's how many come back on day 7. Track that next.
Alright brother ... im taking all the steps i can to bring the users back daily...and honestly this is getting wilder than we expected two user from other countries usig this !! one we found he is from china and other we cant find . but how this is even possible ? we have not spend a single rupee on marketting . i guess the pain is real and my job is keeping them engaged ..so if u ever had some time chekc it out brother and share it with your homies as possible .
Users from China finding it on their own is the best signal you could get - it means it's spreading past the people you DM'd. That's the line between a push and a pull. Keep doing the manual work that keeps them engaged, but start watching where the China users came from; if you can find that channel, that's your next 258 without the manual grind. Will check it out, good luck brother.
alright brother . thank you
258 signups from WhatsApp groups is a strong signal that the problem resonates with people who already know you. The real test starts now: how many come back on day 3, day 7, day 14 without you personally messaging them?
A couple of things worth watching early. First, track where users drop off in the challenge sequence. If most people complete challenge 1-2 and then stop, the adaptive engine might be stepping up difficulty too fast, or the gap between "I watched a tutorial" and "I can write this from scratch" is wider than one challenge can bridge. Consider adding a "hint" step between watching and solving, something like partially completed code where they fill in the key logic.
Second, the WhatsApp distribution channel has a ceiling. College groups are great for the first 500, but they're closed networks. The next step is figuring out where students go when they're stuck on a tutorial (Stack Overflow, Discord servers for specific courses, Reddit learn-to-code subs). Showing up there with a genuine answer plus "I built something for this" is more sustainable than link-dropping.
On the "is this worth working on" question: the fact that 258 people signed up for a learning tool with no brand, no polish, and no ads is a better answer than anyone here can give you. The market is telling you something. Listen to the users who come back without being asked, not the ones who signed up once. Those repeat users are your real product.
Great message man ... yes now we have started to track who all are returning and how they use the platform ... we have been constantly working to improve the platform and can u suggest me some places where i need to pitch to get more users ..
the 'tired of feeling busy but not actually learning anything' line is the most important sentence in this post and it generalizes way beyond tutorial-learning. the shame gap 3vo named above shows up in productivity tools, fitness apps, journaling apps, every category where the actual job is 'help me close the gap between intention and result.' you're not selling code education, you're selling proof-of-progress. the brutal test is whether your D7 returners can articulate that on their own. if they say 'i learn faster now' you have a product. if they say 'i like the streaks' you have novelty.
what a message mannnnn ... Well Anuj18 we will try to increase the percentage of D7 retuners and lets make this product reaches evryones hands
Why are you offering such a good product for free though?
Education should never be a barrier for anyone, because it was once a barrier for me.
That's why we've decided that while Lumetrix Play will eventually have paid features, everything that's free today will remain free forever. Core learning should always be accessible. We'll only charge for advanced features, premium learning paths, and elite-level questions that require additional resources to build and maintain.
And honestly, I'm really happy that you liked the product. If you think it can help someone else, I'd be grateful if you shared it with your friends, classmates, or anyone who might benefit from it. Every person who discovers the platform through a recommendation helps us move one step closer to making quality education accessible to more people.
Feeling productive without actually learning is a painfully accurate problem statement. The strongest products seem to solve frustrations people already know they have.
Exactly.
I don't think the world needs another platform that helps people consume more content. There are already thousands of great videos, courses, and tutorials out there.
What I kept noticing—both in myself and in other learners—was that we often mistake exposure for mastery. We spend hours learning, feel productive, but struggle when it's time to apply what we've supposedly learned.
Lumetrix Play was built around that frustration. The goal isn't to help people watch more; it's to help them master what they invest their time in.
Really glad that resonated with you.
Yes, it's worth working on, but not for the reason you think. The signal isn't 258 signups, signups are cheap. The signal is that you found a group who felt the pain so sharply they got it instantly with no pitch. That's the start of product-market fit, so protect it. Two things I'd watch from here. First, retention over signups: of those 258, how many came back on day 2 and actually finished a challenge? That number tells you whether you built a learning tool or just a better-feeling tutorial. Second, your manual WhatsApp and LinkedIn outreach won't scale, but it just handed you the exact words students use to describe this problem. Write those words down. They become your landing page, your cold message, your everything. You're 18 and already doing the part most founders avoid, talking to users one at a time. Keep doing that long after it feels like you should have automated it.
Thank you sir for your valuable feedback
18, bootstrapped, MSME registered, 258 users in 2 days with zero ads
you're already answering your own question.
Thank you brother
Yes, absolutely. 258 users in 2 days without ads is a strong signal. The biggest positive for me is that you're solving a problem users already feel every day. Keep going and keep talking to users.
alright brother
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
