Runestone to power Raidiant’s calling All Heroes broadcasts

Runestone, an esports data infrastructure provider, has agreed to supply data and analytics services to production agency Raidiant for the Calling All Heroes Overwatch tournament circuit. The company will integrate its tools into live broadcasts for stages taking place in August and September 2026.

Under the agreement, Runestone is named an Official Partner of Raidiant and an Official Associate Partner for the Calling All Heroes stages. Runestone will provide live data feeds and audience engagement technology to Raidiant’s production team for use in match coverage and broadcast presentation.

Calling All Heroes is a gender-inclusive competitive platform launched in September 2022 with support from Blizzard. The 2026 circuit begins in July and uses a three-phase format: an open Swiss regular season followed by an eight-team playoff. Matches will stream on official Overwatch Esports and Raidiant channels and conclude with the Calling All Heroes Raidiant Series 2026 Championship, a multi-weekend event with a $40,000 prize pool.

The 2025 circuit reached a peak of 62,000 concurrent viewers and included sponsor Pura Vida. Runestone’s analytics will be added to production to support broadcast storytelling and fan interaction during the 2026 stages.

Heather Mumm, founder of Raidiant and executive producer of Calling All Heroes, wrote that Runestone’s data and analytics infrastructure will give the production team advanced methods to better understand, serve and activate their audience. Michael Schwartz, head of partnerships at Runestone, added that working with an inclusivity-driven series aligns with the company’s operational values and will help provide technical support and visibility for players.

The agreement marks Runestone’s first official entry into the competitive Overwatch ecosystem. The announcement came one day after Runestone was named data and integrity partner for the Counter-Strike 2 FiReMAJOR Buenos Aires 2027. Recent Runestone agreements include a PGL dataset partnership covering Counter-Strike and Dota 2 through 2029 and 2026 partnerships with SURGE and NODWIN Gaming to support Mobile Legends: Bang Bang esports in Europe and the Americas.
