Traditional freelance missions These are regular project-based opportunities where the listed mission is the actual project you may work on. 2. AI Lab roles For AI Lab roles, we scout, review, and approve profiles for access to future project opportunities. The missions listed for AI Lab roles are not traditional job openings. AI Lab work is often highly confidential as this exposes information of what an AI Lab is working on, and project requests are unpredictable. When an AI Lab request comes in, we often need to respond within 24 hours with suitable talent. Matching depends on the specific needs of each AI Lab project and your niche expertise. Once your profile is reviewed and approved, you may be matched to relevant AI Lab projects when suitable opportunities arise. This can happen within hours, but it may also take months, depending on the researchers at the AI labs and their project needs. ## About 10x Team ## Company Overview - **One-liner**: 10x Team is a European-first platform that assesses, trains, and activates verified professionals (10x-ers) for expert-in-the-loop AI model evaluation, fractional work, and AI fluency building. - **Entity Type**: Private (Seed stage – raised $1.1M in seed round led by Maikel Lobbezoo in May 2024) [linkedin.com](https://www.linkedin.com/company/10xteam) - **Headquarters**: Amsterdam, Netherlands - **Founded**: 2023 - **Founders**: Angelique Schouten (CEO) and Anton Zhelyazkov (Co-founder & Tech Lead) [10x.team](https://10x.team/about-us/) ## Core Business - Primary industries: AI talent platform / human intelligence layer / professional services for AI model evaluation and training. - Target customers: AI labs, enterprise companies, and regulated sectors (finance, legal, healthcare) that need verified European domain experts for model evaluation, human feedback, and fractional AI-native work.
