Oxxi is the AI-native hiring infrastructure for the GCC and MENA. One workspace that unifies the hiring stack. ATS, sourcing, headhunting, job distribution, salary benchmarks, outreach, scheduling, and a talent vault. All running on a memory layer that carries hiring context forward across every role. Built for recruiters, HR teams, and founderswho deserve better.

Oxxi's answer:
Oxxi unifies the hiring stack instead of adding another tool on top of it. The ATS and career pages are free, so the cost barrier that legacy platforms charge for is gone. Itโs built WhatsApp-first, not WhatsApp-as-a-bolt-on, which fits how the GCC and MENA actually hire. And it runs on a memory and context engine that resurfaces overlooked candidates, so your past pipeline keeps working for you instead of going to waste.
Oxxi's answer:
Oxxi is AI-native hiring infrastructure built on a memory layer. Most hiring tools help you find new candidates. Oxxi remembers the ones you already have. It revives dormant CVs sitting in your folders, ATS, and WhatsApp, then matches them to live roles automatically. The core thesis: hiring fails because of memory loss, not sourcing. You donโt lose candidates because you didnโt find them. You lose them because you canโt find them again.
Oxxi's answer:
Companies and recruitment teams across the GCC and MENA region, with a focus on high-volume hiring sectors like F&B, logistics, fintech, and tech. Built for in-house talent teams, agencies, and founders who sit on years of candidate data theyโve never been able to reuse.
Oxxi's answer:
Oxxi started from a hiring agency. While placing senior roles across fintech, F&B, and logistics, the same pattern kept repeating: strong candidates would get archived after one role closed, then forgotten by the next. The problem was never finding talent. It was losing the memory of it. Oxxi was built to fix that, turning wasted candidate data into a living, searchable hiring engine.
Oxxi's answer:
AI agents and large language models for matching, enrichment, and outreach, with a provider-abstracted data layer for candidate retrieval. Built around a memory and context architecture that stores customer-owned candidate data, syncs WhatsApp and career page applicants, and resurfaces matches against live roles.
