Why

Index is an AI HR system for companies that hire skilled trades in Germany. It finds applicants, talks to them, screens them, books interviews and keeps a pool of people for the next role. The applicants are electricians, plumbers, carers and technicians who apply from a phone, often at night and without a CV. The team needed a brand and a product that show how much the system does on its own, and that a person still makes every hiring decision.

How · Brand

We designed the brand: the logo, colours, type, pictograms, ads and posters. The logo is seven dots that form one mark. In the photos, each dot holds a trade.

How · Product

We designed the whole system around one recruiter and their assistant. The assistant runs the job ads, answers every applicant by SMS, email or WhatsApp, asks the screening questions and offers interview slots. The recruiter starts the day with a brief of who needs them. Every applicant comes with a summary that shows where each point came from. The assistant can suggest, draft or act, but rejecting and hiring always stay with a person.

No CV.
No cover letter.
No problem.

Index asks four questions in the chat instead. 58% of people we hired never sent a CV.

Most hires live within 20 km of the job.

Can I still apply?

Our assistant asks questions and finds interview times. Only a recruiter says yes or no.

The loop from ad to hire: the ad runs version B, the chat answers 88 messages today, screening has 17 ready, Anna's interview is at 10:00, and 1 of 3 is hired.

Gap of 17 pointsIndex traced it

Most of the gap comes from one screening question: “German at B2 or better.” It held back 11 people who have B1. Your site lead’s brief says B1 is enough on the job.

Index added this question from the job description on Sep 2. Nobody has changed it since.
