But sometimes you need to see people rolled up to the company level — for example, to count how many matching contacts exist at each company, or to prioritize accounts. ## How to group Apply any filters you need so the grouped view shows only the audience you care about. Click the **Group** button (next to the **Filter** button) and select **Company Name** to aggregate your results at a company level. Group dialog with Company Name selected; data grouped by company with record counts ## Nested groups for territory planning, account prioritization & personalization at scale You can use nested groups to layer your analysis. For example, if you want to know which retail companies have the biggest e-commerce teams: Find the relevant audience (e.g., retail and e-commerce companies in North America and Europe, with revenue and job title filters). Filter dialog for retail and e-commerce with industry, keywords, location, revenue, and job title Group by **Company Name** and add a nested level (e.g., e-commerce department) to see department size at every company and prioritize accordingly. Group dialog with Company Name and Job Title as nested group levels
