The stack they build on and the tools they run — useful for a pitch, a partnership, or sizing up a competitor. It's one of the nine sections in every dossier, and below is exactly what this one does — what it surfaces, where those facts come from, and who leans on it.
What this section reveals
Concretely, the tech fingerprint section gathers:
- Front-end and back-end technologies detectable from the public-facing product and site.
- Infrastructure and hosting signals — where and how the product appears to run.
- Marketing, analytics and sales tools loaded on the site, which reveal how they go to market.
- Tooling named in job postings and engineering content, often ahead of anything on the site.
- A read on technical maturity and direction from the mix of what's in use.
None of it requires the company's cooperation — it's all there in the open record, just scattered until the dossier pulls it into one place. You can see it rendered on a real business in the sample dossier.
How it's sourced
Tech signals are detected from publicly observable surfaces only — the technologies a site loads in any visitor's browser, public DNS and infrastructure records, open engineering blogs and conference talks, and the stack named in job descriptions. Nothing here involves probing private systems or unauthorized access; it's the same fingerprint anyone viewing the public site could read. Detection is best-effort, so the section separates confidently identified tools from likely ones, links the evidence, and notes that the public surface can lag the internal reality — a company may have migrated off something still visible at the edge.
Who relies on it
This section earns its keep for anyone whose work turns on it:
- Sales & BD — tailor a pitch to the exact stack they already run.
- Founders — see how a competitor builds and where they've invested.
- Investors — gauge technical maturity from the tools in use.
