There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they're not AI-native. Our mission is to build proactive applications for anyone in the world, who are not used to complex prompting. We aim to bring intelligence to conversations, errands, organising and workflows, with minimal to no prompting.
Our first application is an agent-first mobile communication app. We believe building applications that users use daily for communication, coordination and collaboration needs will help integrate AI into their lives. The net effect is to eliminate misinformation, achieve low coordination costs, enable high quality tasks and collaboration at scale with minimal or little prompting.

Estimated take-home pay
Explore gross pay after typical payroll taxes for a work location.
Illustrative estimate only; assumes a standard employee profile and may omit benefits, pensions, credits and local rules. Regional and city-specific tax applies only where the selected calculator supports it; other results are country-level. Salary and location are sent only when you calculate: Paysums for supported regions, or WorthOf for wider country coverage. Confirm with an official payroll or tax source before making decisions.
Visa sponsorship and relocation: not stated in the ad.
JobCheckPoint never asks candidates to pay, and genuine employers shouldn't either. If this job asks you for money (registration, training, visa or equipment fees), don't pay. Report it below.
