Common Questions

Everything you need to know.

Quick answers to the questions we hear most often, from candidates and companies alike.

Yes, always. We never charge candidates to register, apply, or access opportunities. Our business model is funded entirely by the companies that use our network. Any platform that charges you a "registration fee" or "access fee" to find AI work is not a legitimate operator.

No specific degree or certification is required. What matters is clear thinking, attention to detail, and domain expertise in your field. We have contributors ranging from recent graduates to senior professionals: doctors, lawyers, engineers, developers, linguists, and generalist writers. Roles are matched to your background, not a checklist.

Response times vary depending on the partner company and their current hiring activity. Some move quickly. Candidates have heard back within 1–2 days. Others may take up to 4 weeks depending on project timelines and volume. Communication is managed by the partner platform, not by Crossing Hurdles directly. We recommend keeping an eye on your inbox and checking your spam folder.

Our network is global and most AI training work is fully remote. We have contributors in 50+ countries across Africa, Asia, Europe, Latin America, and beyond. Some specific projects may have geographic or language requirements, but we always make those restrictions clear upfront.

Payment terms and methods are set by each project and disclosed before you commit to any work. We only place contributors on projects with clear payment structures: hourly, task-based, or milestone-based. We never withhold payment or create surprise deductions. Payment is typically processed via the project platform (such as Appen, Scale, or Surge) or directly for managed service engagements.

For most standard profiles, we can provide a shortlist within 3–7 business days. For specialist roles (medical, legal, highly technical) or large-scale staffing, allow 1–2 weeks for a full-quality shortlist. Our managed service model can also embed a vetted contributor team within your workflow for ongoing projects.

We are a network and connector, not a platform with our own projects. We match contributors to opportunities across a broad range of AI labs, research platforms, and enterprise AI teams. We're also differentiated by our focus on the Global South and underrepresented contributor pools, and our strict no-fees-for-candidates policy. We don't just list jobs. We actively advocate for the contributors in our network.

Our Story

Built to open a door most people didn't know existed.

Crossing Hurdles started with a simple observation: the AI economy was generating enormous demand for skilled human talent, but the people best qualified to contribute had no reliable way to find it. Opportunities were fragmented, platforms were opaque, and the Global South, despite having millions of highly educated professionals, was consistently underserved.

We built Crossing Hurdles to be the bridge. No candidate fees, ever. No false promises. Just genuine access to meaningful AI work, handled with transparency from start to finish.

"The AI economy should be open to everyone with the skills and dedication to contribute, regardless of where they live or how well-connected they are. That's the company we're building."
