03Talent

The right AI team, matched to the right problem.

Talent is where DT21 lives day to day — through Alteam, the AI-powered talent platform I founded.

Why

Great talent is everywhere. Opportunity isn't. We find brilliant, underrepresented tech talent that the startup world overlooks and match them to the problems where they will do their best work.

What

Alteam is the right AI team. It is an AI talent platform that helps startups hire vetted, senior tech teams in days, not months, with a focus on underrepresented talent most platforms miss.

How

1Describe your brief or ideal candidate.
2We understand the problem. AI analyses scope, risks and complexity, validated by our CTO and CPO.
3We assemble the right team. AI matching with human review surfaces underrepresented talent others miss and forms a focused delivery pod.
4We deliver or help you hire with confidence, extending the team only if it makes sense.
