There is a version of the startup story that gets told over and over. The founder had a vision. They built the thing. Users came. Money followed.
My story does not go like that.
I am 18 years old, I live in India, and on November 10th 2024 I opened my laptop and started building something I had never built before. Not a small script. Not a school project. A full SaaS product — an AI landing page builder called Sento AI — completely alone, with no co-founder, no mentor, no funding, and no real roadmap.
What followed was four months of things going wrong in almost every possible way.
The Image Problem That Ate Ten Days
The core idea behind Sento AI was simple: a user types one sentence describing their product, and the AI generates a complete, professional landing page in seconds. Hero section, pricing table, testimonials, call-to-action — everything.
Getting the text to generate correctly took weeks of work. But then came a problem nobody warned me about.
The images were wrong. Every time.
When the landing page generated, the images pulled from libraries had nothing to do with the product being described. A fitness app would get photos of office furniture. A SaaS tool would get pictures of mountains. And every time the page refreshed, the images changed again — completely random, completely useless.
I tried everything I could think of. Different image libraries. Different file structures. Different ways of passing context to the generator. Nothing worked consistently.
For ten days I sat with this single problem. Not ten days of steady progress. Ten days of trying one approach, watching it fail, trying another, watching that fail too.
The fix, when it finally came, was something I almost missed. I modified the generated HTML itself to extract a relevant keyword and pass it directly to Unsplash as a search query. The images snapped into place. Suddenly a fitness app got people running. A SaaS tool got clean desk setups. The page looked like it was designed by someone who understood the product.
Ten days for one fix. That is what solo building actually looks like.
Three Illnesses, One Semester Exam, and a Family That Did Not Understand
Building the product was only part of the problem.
In December, while deep in development, I got sick. Fever, cough, phlegm, headaches — the kind of illness that makes sitting upright in front of a screen feel like a punishment. It lasted seven days. I worked through some of it in fragments, thirty minutes here, an hour there, but the momentum broke.
I recovered. I came back. I kept building.
Then a stomach issue hit. Three days gone. Then in February, another fever as the seasons changed — this one lasting more than five days.
Between the three illnesses, I lost roughly three weeks of productive work spread across the build. But the biggest single blocker was not sickness. It was the semester exam in February.
For fifteen days, the laptop stayed closed for development. Not because I wanted to stop. Because in my house, in my situation, there was no choice. College existed before Sento AI in the order of priorities that other people controlled.
When the exams ended I came back to the codebase like someone returning to a house they had left in a hurry. Things were where I had left them. The problems were still there. The work was still unfinished.
I picked it back up.
The Payment Wall
By early March the product was functionally complete. The AI generated landing pages that looked genuinely professional. The publishing system worked. The analytics dashboard tracked visitors. The custom domain feature was live.
There was just one thing left. Payment processing.
Stripe rejected my application.
PayPal rejected my application.
Lemon Squeezy rejected my application.
Each rejection came with a waiting period — days of hoping the appeal would work, days of reading documentation trying to understand what went wrong, days of watching the launch date slip while the product sat finished and unusable for paying customers.
Five days passed in this cycle of applications and rejections. For someone who had spent four months building something that worked, being blocked at the final step by paperwork felt almost designed to break me.
I found DodoPayments. Applied. Got approved. Integrated it in a single night.
On March 5th, 2025, Sento AI went live at sento24.com.
Six Users. Zero Revenue. One Question.
There was no big launch moment. No ProductHunt spike, no viral tweet, no flood of signups. I started doing what I could — posting on X, leaving comments, submitting to directories, making videos, building in public from day one.
Six real users signed up. Three of them actually generated complete landing pages using the product. Professional pages, ready to publish, built from a single sentence exactly as the tool promised.
Then they disappeared. No upgrade. No payment. Nothing.
The pricing was $5 a month. Not $50. Not $99 like Unbounce charges. Five dollars.
I did what most founders do first — I guessed. Maybe the free tier was too generous. I cut it. Maybe features were missing. I checked — they had everything. Maybe $5 was somehow still too high. I looked at the numbers and could not make that math work.
The guessing was not working. So I did something harder.
I emailed all six of them. Not an automated sequence. Not a survey with twenty questions. One email, written personally, with one question:
What actually stopped you from paying?
That answer — whatever it turns out to be — is worth more than any assumption I could make sitting alone at my desk.
What Sento AI Actually Does
For anyone unfamiliar with the problem Sento AI is trying to solve: building a landing page the traditional way takes time that most early-stage founders do not have.
You need to choose a template, write copy, find images, set up a domain, configure analytics, and make everything look professional enough that a stranger will trust you with their email address or their money. Tools like Unbounce and Leadpages help, but they charge $49 to $99 a month and still require significant manual work.
Sento AI's approach is different. You type one sentence. The AI generates the entire page — structure, copy, images, sections — and it is ready to publish immediately. From there, any section can be refined further using AI assistance. The whole system is built around the reality that most founders need something live and working today, not a perfect page two weeks from now.
It is built with React, runs at sento24.com, and starts at $5 a month.
The Doubt That Never Fully Goes Away
I will not pretend the journey has been clean. There are days when the idea of listing Sento AI for sale on Flippa feels more rational than continuing to push. Days when the question of whether any of this will ever work sits heavy alongside everything else — the family pressure, the college schedule that eats my mornings, the comments and videos and directory submissions that feel invisible.
I am eighteen. I built something real. I shipped it. I am talking to users.
That is further than most people who have the same idea ever get.
The story is not finished. But it is also not over.
