Learn more →I’m Nikos. I started Plumbnote in April 2026, in a small office in Bratislava, because I got tired of spending 45 minutes rewriting every angry-customer email and wanted a tool that would let me handle it in 60 seconds instead.
I built a prompt pack for myself, realized I had five more versions of the same need, and turned the first one into a product. That’s the Calm Customer Kit. More are coming.
Everything here is hand-crafted — no templates, no cookie-cutter, no AI-generated filler. I build each tool from real experience with the mess it’s meant to fix, I use it myself for weeks before I ship it, and I sell it directly without middlemen. No ads, no affiliate schemes, no upsell funnels.
The name comes from the idea that running a small business on your own isn’t about being a genius — it’s about having a plumbnote when things get bumpy. That’s what these tools are for.
