Strategic proximity
HKR.AI is a global AI partner that builds and operates AI-augmented teams on behalf of US-based companies. Our European roots and US presence make us a reliable partner for founders and operators who want outcomes — not overhead.
How we got here
One person
Sergiu Poenaru started as a remote worker for a US company in 2016. He delivered at a high standard, so the company asked him to find more people like him.
Beyond CS
Growth was entirely organic — one client recommended the next. Services expanded from customer service into operations, sales, and specialized roles.
Going global
International infrastructure across 20+ countries. EOR coverage in 150+. Geography expanded to South Africa, LATAM, Philippines, Europe, and beyond.
People + AI
HKR.AI is the next evolution — the same operational excellence, now amplified by AI agents that deliver outcomes at scale. Fewer people, better results.
The people running it
A lean leadership team with 10 years of embedded operational experience.

The team behind the teams
Clear expectations, direct feedback, ownership. Everyone knows what's expected, gets honest feedback, and has the autonomy to deliver. No performance theater — just performance.
Our eNPS of 78 (anything above 50 is excellent) isn't from perks — it's from clarity, fairness, and the kind of work people are proud of. Average tenure with the same client: 5-7 years. Attrition rate: under 4%.
The AI Manager model
You pick the outcomes. We handle everything that comes after: designing agents, deploying them, managing their performance. Every deployment gets a dedicated AI Manager from day one.
At HKR.AI, feedback goes both ways and nobody waits for a quarterly review. AI Managers flag issues in real-time, tune agent behavior weekly, and report results to your leadership directly.
