Kombo (YC S22) is building a unified API for HR, payroll and recruiting systems that saves engineering teams hundreds of hours by needing to integrate only one API instead of 50+.

Culturally, we are looking for ambitious yet kind builders - we like to describe ourselves as a "SF startup but in Berlin".

Water is building AI that helps people accomplish goals, not just answer questions. Most AI systems are designed to follow instructions. They wait for the user to decide what to ask, what matters next, and what should be done. Water starts somewhere different: the goal. Tell Water what you want to accomplish. It builds the path, understands your progress and context, determines what matters next, and helps execute the work across AI, software, and people. The result is a new interface for getting things done: instead of managing prompts, tasks, workflows, and agents, the user focuses on the goal while Water helps direct the journey. We are starting with founder/operators — people with ambitious goals, small teams, and too many tools competing for their attention. The MVP is approaching launch, and we are building the initial founding team around a larger thesis: AI should not just be capable of doing almost anything. It should help people determine what is actually worth doing.

Radiology is the second most used healthcare service, used by over 51% of the workforce annually.

Our solution helps patients and families access essential radiology services at fair prices and without surprise bills, all while delivering immediate savings and ROI for employers and payers on every exam.
