About Us

We teach what we know

DeeLab Academy is the training and certification arm of DeeLab. Our parent company, Tailjay, is headquartered in Singapore, but we operate globally — with a distributed team and trainees from every corner of the planet. We teach what we know from real project work.

Figures reflect our formal certification programme since its public launch in March 2025. Our first corporate training ran in November 2024, before the programme opened publicly.

Our story

Born from practice, not theory

DeeLab started as a data annotation services company. Over time, we noticed something consistent: the quality of annotation work — whether done in-house or by clients — depended heavily on how well people understood the full pipeline.

Not just how to draw a bounding box, but why the label matters, how it feeds into model training, and what makes a dataset genuinely useful for the task at hand.

We began training our own teams formally. That internal curriculum — refined through hundreds of real annotation projects across image, video, audio, text, and 3D data — became the foundation of DeeLab Academy.

Our first corporate training programme ran for a client team building annotation capability in-house. The results were strong. We opened the programme publicly. DeeLab Academy was born.

Our team

Built and taught by industry practitioners

DeeLab Academy courses are designed and delivered by a team of five industry practitioners with multi-year hands-on experience in data annotation, AI project management, and labelling operations.

The curriculum was built collaboratively, drawing directly from real project work. We are open to adding new domain experts as the course catalogue grows.

We collect structured feedback after every course and read every response. That feedback loop has shaped every iteration of our curriculum — and will continue to.

Founder

Kari Kinnunen

Kari founded DeeLab Academy as the training arm of DeeLab — the data annotation services company he leads through Tailjay, his Singapore-based venture builder. He set up the Academy to share what DeeLab learned running annotation projects across image, video, audio, text, and 3D data — distilling that experience into a curriculum that holds up in production, not just in demos.

His background spans startup operations, team building, and digital strategy.

“Real data, real teams, real deadlines. We're teaching what works in the wild — and what doesn't.”

Hannah Ndulu

Hannah designs and runs DeeLab Academy's training and certification programme — equipping annotators with practical skills they can apply on real client projects from day one. Based in Kenya, she also leads DeeLab's core annotation team, so what she teaches comes directly from active project work, not theory.

Her background spans bookkeeping and data annotation operations, which feeds into the meticulous, detail-driven approach she brings to every course.

“I'm passionate about precision and quality — making sure trainees leave with skills that hold up under real client pressure, not just in practice exercises.”

A note on our certifications

DeeLab Academy certifications are issued by Tailjay Pte. Ltd. and represent our rigorous assessment of your competency. There is no formal external accreditation body for data annotation training yet — we built our system to industry best practices and remain open to external audit as the field matures. We are transparent about this because we think honesty matters more than inflated credentials.
