Almost every company has an idea that keeps getting pushed back. But it is hard to invest in uncertainty. Until you try something, you do not know whether it makes sense or whether it will work.
That is why on Friday, July 31, we will choose three applications with the strongest potential and build a working prototype for them for free - work worth up to EUR 3,300. No lengthy specification, no commitment. The point is to quickly find out whether the idea is worth the next step - and you leave with evidence, not just a feeling.
A website, configurator, calculator, or customer portal that could sell better. A process held together by Excel. An internal tool that would save hours of work. Or an AI agent that would sort inquiries, monitor data, prepare materials, and free people up for higher-value work.
We are not looking for a contest for the “best app”. We are looking for real problems with an owner, impact, and room to grow.
A few minutes and a few sentences about what is slowing you down or what you would like to try are enough.
At Sinfin, we design and build custom web applications, publishing platforms, e-commerce, auctions, and AI agents.
A few things we have built recently. The same pattern every time: a specific problem, a specific solution.
You sell well, but only at home. We connected AI to an e-shop that translated the entire catalogue into EU languages - keeping technical terms, prices, and shipping right for each market, and preparing each version so Google reads it as a local-country website. No translators, no per-page translation billing, and automatic.
Customers cannot picture the product. We built an app where customers can use their own photos to arrange pictures on a wall, view them on their wall through mobile Augmented Reality, and get a hanging plan. Less hesitation, larger carts.
You want to sell live and remotely. We launched live auctions with a near-zero-latency stream from the room and real-time bidding - and handled hundreds of people at once when money was on the line.
Someone in your company spends whole days matching payments by hand. We programmed a process that downloads bank and payment gateway transactions, uses AI to match invoices, calculates fees, and prepares documents for accounting. A person just approves. Tested on a combination of e-shop, bank, Flexibee, and wflow, and it can find forgotten invoices and receipts in email and on disk.
You collect ideas for a company blog, but you do not have time to write. We built an agent that turns saved posts into a verified article in perfect Czech, creates images, and after your approval publishes it in twelve more languages - including an audio version.
You sell one-off, even though customers would gladly come back. We prepared a subscription for a coffee roastery: the customer sets once how often they want coffee delivered and then does not have to do anything else. One-off purchases become recurring revenue.
Every time, it starts with an ordinary problem or an idea that was put aside - and ends with something that saves time, opens markets, or earns money. Your “what if” can be next.
