A software company with one product and one person
QuantumCX builds pSEO Engine, programmatic SEO software sold to agency owners, freelance SEOs and in-house marketers. It researches the queries worth building pages for, writes the page set, publishes it to a domain you control, and tracks where it lands.
Who runs it
Baibhab Bose. I write the software, I answer the support email, and I am the person you will be dealing with. QuantumCX is a private limited company.
That is worth saying plainly rather than hiding behind a plural. If you are an agency owner who has been ghosted by a SaaS vendor before, a named person who answers their own email is not a smaller version of a support queue — it is a different and better thing. It also means I am not going to pretend there is a team here, or that this has been running for a decade.
What we are building toward
One product, done properly. pSEO Engine already does the full run — research, design, generation, review, publishing, rank tracking, AEO and GEO optimization — and the work now is depth rather than breadth: better research qualification, better templates, better reporting for the client sitting on the other side of your invoice.
We are deliberately not adding a second product, and we are deliberately not chasing enterprise. The buyer is an agency owner who bills a client for results and needs the page set to exist by Thursday.
Why the tool audits its own marketing site
pSEO Engine ships with the same review stack it sells: near-duplicate detection, section-reuse checks, unsourced-claim detection, and answerability scoring. We run that stack on this very site — the same free audit anyone can request — and fix what it flags here before we quote findings from anyone else's site. When the audit of quantumcx.net comes back clean, that is the demo: the tool keeping its own house in order, in public, on a one-person company's website.

Proof, such as it is
One client engagement is public: 500 pages published for a makeup artist, on his own domain, with rank tracking running. One client is one client, and the case study says so. You can open the live site and count the pages.
