SOLON & CO.

Judgment is the hard part of AI.
We recruit it.

Solon & Co. builds and fixes talent pipelines for AI companies, run by Oto Attang, who until August 2026 helped lead one of the world's largest AI expert marketplaces at Invisible Technologies ($2B+ AI training company): 15,000+ experts placed personally across 120+ countries and 94 languages for programmes serving Google, Microsoft, Meta and OpenAI.

Three ways we work

Fractional Recruiting

AI and technical sourcing, full-cycle recruiting, and pipeline operations for AI companies. Fifteen to twenty hours a week, month-to-month, productive from day one.

From $85/hour

Talent-Ops Sprints

Fixed-scope engagements with a deliverable you keep: pipeline rescues, rate architecture, assessment-integrity audits, and recruitment media planning.

€5–15K · 2–3 weeks

Expert Consultations

AI workforce economics for investors, strategy teams, and operators: rates, supply, vendor landscape, and fraud. Via GLG, AlphaSights, or direct.

By the hour
The Operator

Built at the largest scale in the industry

I joined Invisible Technologies as a sourcer on what became one of the world's largest AI expert marketplaces, and finished leading a 30-person talent operation. In 2024, before the promotion, I owned 144 concurrent requisitions that delivered 4,500+ hires at an 86% fill rate, including a 500+ seat programme filled at zero attrition through delivery.

Along the way I built the sourcing funnel that brought 15,000+ experts onto the platform, identified LLM-aided cheating as a systemic failure mode, initiated the expert-gated verification standard that replaced the automated test and directed its build with my assessment team, wrote compensation policy across 70+ countries, and modelled a six-figure multi-channel talent-acquisition plan costed per approved expert.

Since September 2026 I am on contract in expert supply with two AI-data companies; Solon & Co. takes a limited number of engagements alongside.

Now that machinery works for you.
