Rent.

Based on the limited information provided with just the company name 'Rent.', I cannot identify a specific AdTech company with sufficient confidence. There are multiple companies with 'Rent' in their name across various industries, including Rent the Runway (fashion rental), Rent.com (apartment listings), and others, but none are primarily AdTech companies. Without additional context such as a domain name, full company name, or other identifying information, I cannot provide accurate details about a specific AdTech entity named 'Rent.' It's possible this refers to a smaller or regional AdTech company, a recently launched startup, or there may be confusion about the company name.
