About Yendou · Berlin, Germany

Bring the next breakthrough closer.

Clinical expertise that compounds.

Every clinical programme builds on scientific discovery. It should also benefit from everything an organisation has learned about patients, sites and delivering studies.

Our ambition is to make that knowledge compound, expanding what teams can investigate today and what their organisation can draw on tomorrow.

Your expertise. Operating at a new scale.

Whether you are developing your first programme or building on years of trial delivery, Yendou expands the specialist capabilities available to your team.

We combine your scientific and organisational knowledge with specialist AI analysis, external clinical intelligence and direct site engagement. Together, these inform your strategy and build your institutional memory.

More capability today. More knowledge for tomorrow.

01

Expand your team’s specialist capacity.

Yendou’s AI teams investigate protocol requirements, patient pathways, competition and site capabilities alongside your organisation’s evidence and experience.

02

Connect strategy with site evidence.

Engage sites directly on Yendou. Bring their feedback into the assessment of patient access, protocol fit and delivery capacity.

03

Build institutional memory through the work.

Keep recommendations, supporting sources, site responses and expert-reviewed answers connected to their context. Give future teams access to the evidence and reasoning behind previous decisions.

Clinical depth. Commercial strength.

Zina Sarif, Founder and CEO of Yendou

Built from inside clinical development.

Zina Sarif’s work in cancer research and clinical development, including at AstraZeneca, brought her close to the decisions connecting a potential medicine with the clinics and patients needed to study it.

Yendou grew from that experience: a conviction that clinical teams should be able to combine what they know with what they need to discover, and preserve what they learn for the programmes that follow.
