A Polish developer with a full-time job grew his AI rendering tool for architects from about $150 to nearly $10K a month after one pivot
Piotr built Visualizee on nights and weekends. It sat near $100 to $150 a month for two years until he replaced a complex node editor with a simple chat.
Subject: Visualizee (Piotr)Subscription AI rendering tool for architects and interior designers, with a 7-day free trial and $35 or $80 monthly plans

Case Overview & Background
Piotr is a software engineer and tech lead in Poland who built Visualizee, an AI rendering tool, alongside his full-time job. Architects and interior designers upload a sketch or model and get a realistic render of a home or interior in seconds. He says the product was stuck at around $100 to $150 a month for its first two years. About six months before the interview he simplified it into a chat-style assistant and switched to subscriptions, and he says revenue grew to an $8.2K MRR, close to $10K a month with one-time payments.
How AI Is Used
Step-by-Step Process
Instead of a general AI image toy, he focused on renders for architects and interior designers.
His first version was a node-based editor that he says was too hard to understand.
He rebuilt the experience around a ChatGPT-style assistant that helps people say what they want.
He moved from one-time payments to a free trial and monthly plans, which he says drove the growth.
Customer Acquisition & Distribution
Limitations, Risks & Failure Modes
What may not apply to you, and what could go wrong:
- The figures are self-reported and were not independently checked
- It took about two years of near-zero revenue before the pivot
- The product depends on third-party AI image services and their costs
- Many competing AI rendering tools exist
Key Takeaways
- Friction in a product can look like a marketing problem
- A simple chat interface can make an AI tool usable for non-technical professionals
- Recurring subscriptions built steadier revenue than one-time payments for him
