Executive summary
Q3 2025 revenue was $68.0M, with adjusted EBITDA of $11.2M (16% margin), and a GAAP net loss of $6.5M; strong cash flow and margin improvement were driven by CTV, online video, and mobile app growth, as well as AI innovation and operational efficiency.

Diversification efforts resulted in over 40% of revenue from CTV, mobile app, and emerging streams, up from less than 30% two years ago.

excellent app, it gives me free access to company earnings calls and annual reports. I also love the convenience of calls being available offline so I can listen in whilst doing other things and even when internet or WiFi isn't available.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
