Esports data infrastructure provider Runestone has closed a partnership with production agency Raidiant to power the gender-inclusive Overwatch tournament circuit Calling All Heroes (CAH).

The agreement designates Runestone as an Official Partner of Raidiant, a women-founded and women-led company, and as an Official Associate Partner for the upcoming CAH tournament stages scheduled across August and September 2026, marking the data firm’s entry into the competitive Overwatch ecosystem.

Originally launched in September 2022 with the official backing of game publisher Blizzard, Calling All Heroes serves as a critical competitive equity platform designed to empower underrepresented communities within Overwatch. The 2026 circuit, which kicks off this July, features a revamped three-phase format consisting of an open Swiss regular season and an eight-team playoff stage.

Live tournament coverage will be broadcasted directly on official Overwatch Esports and Raidiant channels. The competition will culminate in the multi-weekend Calling All Heroes Raidiant Series 2026 Championship, featuring a $40,000 total prize pool. Runestone will integrate its specialised data and engagement tools into the live broadcasts, building on the momentum of the 2025 circuit, which captured a peak of 62,000 concurrent viewers and featured jewelry brand Pura Vida as a sponsor.

Heather Mumm, Founder of Raidiant and Executive Producer of Calling All Heroes, stated that incorporating Runestone’s data and analytics infrastructure will give the production team advanced methods to better understand, serve, and activate their highly engaged fanbase. Michael Schwartz, Head of Partnerships at Runestone, added that entering the Overwatch competitive scene via an inclusivity-driven pipeline aligns directly with the firm’s core operational values, ensuring that talented players receive the necessary technical backing and visibility as the broader gaming market continues to diversify.

The expansion into Blizzard’s hero shooter ecosystem comes just one day after Runestone was announced as the data and integrity partner for the Counter-Strike 2 FiReMAJOR Buenos Aires 2027. The back-to-back announcements continue a rapid period of market expansion for Runestone within tier-one tactical and mobile esports. In recent months, the data infrastructure provider has finalised major data agreements across several flagship titles, including a comprehensive PGL dataset partnership for Counter-Strike and Dota 2 circuits through 2029.

Runestone has targeted the mobile esports ecosystem through partnerships within the Mobile Legends: Bang Bang (MLBB) scene. In 2026, the company has partnered with SURGE and NODWIN Gaming for MLBB esports development across Europe and Americas, respectively.
