Exit
In 2025 Blis was acquired by global telecommunications company T-Mobile which valued the business at $175 million. During the period of Maven’s investment, the business has invested heavily in its technology platform, increased headcount from 240 to more than 320 employees, expanded its international footprint, and increased turnover by 75%.
"Blis provided Maven Investor Partners with a unique off market opportunity to invest in a fast-growing programmatic advertising business at an attractive valuation. The sale to T-Mobile marks an excellent outcome for the business, its management team, and our investors. With a best-in-class platform and talented team, Blis has firmly established itself as a leader in its field, making it a highly attractive acquisition.
