# startDepthChart

`POST /v1/depth-chart/start`

**Tags:** `Company info`

Start depth chart generation

**Endpoint:** `https://api.fiber.ai/v1/depth-chart/start`

## Description

Generates a breakdown of the number of employees at a given company by department/function (Engineering, Sales, Marketing, etc.), seniority (Junior through Executive), or both. This helps answer questions like, 'how many senior engineers does this company have?'. Asynchronous; use the polling endpoint to get your results. Processes up to 10,000 employees per report.
