Competitive landscape
Edge: Founding team led Valorant's development at Riot — proven live-service multiplayer execution. a16z gaming network and Jonathan Lai board seat provide strategic support.
Ex-Riot founders entering indie studio space is a proven pattern (Embark, others). Raid Base's sandbox PvPvE genre is crowded with both AAA and indie titles. Differentiation depends on execution quality and live-service infrastructure — areas where the Valorant team's experience is directly relevant. No public gameplay has been shown as of 2026.
