Case Study: SoftBank achieves scalable innovation and accelerated growth with Slack

SoftBank scales innovation and accelerates growth with open collaboration

SoftBank, a diversified telecommunications and tech conglomerate of more than 260 companies and ~40,000 employees pursuing a Beyond Carrier strategy, found its fast‑moving culture hampered by slow, fragmented communication: heavy reliance on meetings, emails and disparate collaboration tools made decision‑making, knowledge sharing and execution inefficient across its large organization.

To fix this, SoftBank adopted Slack company‑wide (after early internal success), moving to secure, channel‑based messaging integrated with key apps and automated workflows. The change reduced meetings and email overload, scaled knowledge across teams, replaced manual notifications with real‑time updates, and accelerated decision‑making and partner collaboration—benefiting 20,000+ employees and supporting faster business growth.
