Which one should you pick?
Choose Athyna if…
- AI-training and research staffing. If you need annotators, model evaluators or RLHF researchers, that is a specialism we do not have.
- A stated 5-day match is materially faster than our 21-day average.
- Algorithmic matching scales better if you are filling many similar roles at once.
Choose Nexus if…
- You want a person running the search and defending the shortlist, not an algorithm's output.
- The role is a conventional full-time hire rather than research or annotation work.
- You want a published replacement guarantee — they do not publish one.
Athyna is the stronger choice for AI-training and research staffing, and it is faster to a match. Nexus fits conventional full-time hiring where you want a human-run search and a written replacement guarantee.

Questions people ask
Is a 5-day match better than a 21-day hire?
