Eight years into a Salesforce developer job, Jakub Muzik knows the feeling of trading time for money without much enjoyment attached to it. Corporate work grows repetitive after enough years inside it, and the work itself stopped being something he looked forward to a long time ago.

Four years ago, for his bachelor's thesis, he built a mobile app: a simple social media tool that mapped a user's location and showed local events nearby. It was the first time he had built something people actually downloaded and gave positive feedback about, and the feeling stuck with him. Since then he has been building side projects nonstop in his free time.

He has built countless apps. Most made nothing. Then one finally clicked, almost immediately: a social media lead generation tool called Leadverse. The idea is simple. You paste in your product or service, and the tool continuously searches for new social media posts from people asking for exactly what you provide. Because outreach only ever targets people already asking for help, it avoids the spam feel of cold email entirely, and since the follow up messages are automated too, it brings in traffic on autopilot.

Leadverse has now crossed $20k in gross revenue, with more than 130 paying customers and $3.3k in MRR.

Here is how a busy engineer with a newborn at home built it on nights and weekends, and what his pricing experiments taught him about trust.

Ten months ago, Jakub saw a post on Reddit. Someone was asking other builders what they were working on, offering to send them Reddit posts from people actively seeking their exact solution. The post went viral. Hundreds of people commented, all needing help with lead generation, and Jakub noticed the pattern before anyone else seemed to capitalize on it fully.

So he built his own version of the idea as a real product rather than a one off favor. That distinction, turning a viral moment into infrastructure, is the whole story of how Leadverse came to exist.

Jakub builds solo and fully bootstrapped, on nights and weekends. His development background made the technical side of building Leadverse relatively straightforward, and the MVP took about a month. The real constraint was never skill. It was time. Between the 9 to 5 job, freelance gigs, and a family that recently grew with a new baby, finding free hours to focus on side projects has been his single biggest challenge throughout.

Once the MVP was ready, he posted on Reddit using the same format he had seen work before: asking other builders what they were building and offering to send them leads for free. The post went viral exactly as he expected, bringing in traffic and his first paying customers in the same wave.

The stack behind Leadverse is compact:

The biggest technical challenge has been balancing LLM costs against output quality. The entire lead generation engine is fully AI powered, and LLM API calls account for roughly 90% of Jakub's total costs. He is continuously optimizing prompts and testing different models to cut expenses while keeping output quality where it needs to be.

Jakub started with a freemium model. Anyone could sign up and use the tool until they hit a certain number of leads. It felt like the safest option available, and it was not.

His main traffic source is Reddit, which comes with a specific tradeoff. Many users who arrive that way have no real intention of using the tool long term, and a share of them sign up purely to test the free tier once and disappear. Reddit is genuinely excellent for growing traffic, but it also means accepting somewhat lower user quality, and that quality gap was quietly inflating his cost per user in a way the freemium model could not absorb.

He switched to a three day free trial requiring credit card details upfront, and improvement showed up almost immediately. Fewer people started the trial, but the conversion rate climbed substantially. Less money went to non serious users, and more revenue came from people who actually intended to use the product.

Then he extended the trial from three days to seven, and the numbers improved further. Three days was simply too short for people to see the value clearly. He still runs a seven day trial today and has no plans to change it.

On pricing, Jakub initially assumed cheaper would convert better. He was wrong, and the data told him so consistently. He experimented extensively, lowering prices for a few weeks, raising them, and watching the results closely each time. Lowering prices never improved conversion. If anything, it did the opposite: below a certain threshold, trust decreased and the product started to feel low quality, and people bounced before even trying it.

He also started noticing fake users more often at low price points, people using cards that predictably fail after a week for insufficient funds. He had no idea that pattern existed until running his own SaaS and watching it happen firsthand.

He started with a 9 euro plan and a 14 euro plan. After about a month he switched pricing from EUR to USD, and conversion increased with no other changes made at the same time. A few months later he added a third $19 plan along with a custom plan option, letting users adjust limits and pricing to their own needs. That custom tier turned out to be another significant turning point. Around 30 users have opted into it so far, and Jakub is candid that he cannot believe he did not add it sooner.

All of Jakub's revenue has come organically from Reddit, through two specific tactics:

Beyond Reddit, he has built a few free tools and optimized his page for search engines, though he has not seen much conversion from that organic traffic yet and considers it unfinished work. He started that effort months after launch and openly wishes he had started it from day zero instead.

He has also tried affiliate partnerships, and now has more than 20 partners on board. He has not seen meaningful conversions from that channel, and it is not something he would recommend based on his experience so far.

Jakub started with a very simple landing page and made a sequence of specific changes over time, in this order:

Every one of these changes drove conversion higher, and none of them required rebuilding the product itself.

Building in public on X has also been a real advantage. Jakub regularly posts his progress, insights, and failures within the Build in Public community, which has helped him meet other founders and stay inspired by what they are doing.

His core advice distills to two words: get inspired. You do not need to reinvent the wheel. Look at what already works, whether that is a product idea, a marketing strategy, or a specific post pattern that keeps performing. Surround yourself with people who share your interests, get inspired by them, share your own learnings in return, and keep going.

From here, Jakub's goal is straightforward: build enough recurring revenue to leave his 9 to 5 job and go fully into indie building.
