Where is the demand coming from?
Mixed
Some genuine outside demand, some founder reach. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimateWe do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 9 weeks
Nothing patented, no network effect, and no proprietary data set standing in the way.
What it is
Pyx is a local-first, Rust-built portfolio tracker for macOS/Windows/Linux that stores encrypted investment data on-device and integrates with AI agents via a local MCP server. The product emphasizes privacy, deep financial analysis (18 years of company fundamentals), and honest performance calculations, charging $7/mo or $70/yr for brokerage sync.
The one thing to knowThe core value prop is defensible privacy and local compute, but the build complexity (Rust desktop app, brokerage API integrations, SEC data parsing, charting) and small detected community signal suggest limited near-term traction or obvious wedge angle for fast followers.
