Parallxeo

Parallxeo is an AEO agency that makes B2B SaaS brands the default recommendation when buyers ask AI which tool to use.

AEO stands for Answer Engine Optimization. It is the discipline of earning citations inside ChatGPT, Claude, Perplexity, and Gemini, the four engines that already shape most B2B software shortlists before a buyer ever visits a vendor website.

We started as an SEO agency. Our cofounders came up through statistics and information retrieval and went deep on how large language models decide which brand to cite on a query. That work covers tokenization, embedding distance, retrieval-augmented generation, and the third-party sources a model assigns authority to for a given category. We rebuilt the methodology around one question. When a real buyer asks an AI which ATS, legal tech, or dev tool to use, does this brand show up.

Three services anchor the work. The 90-day audit measures your citation rate, share of voice, and per-engine ranking across 150+ buyer queries. Citation campaigns earn coverage inside the third-party sources those engines actually trust for your category. The weekly tracker ships every Monday.
