Case Study: Sumitomo Mitsui Banking Corporation launches Trunk and transforms SME banking with ABeam Consulting

Sumitomo Mitsui Banking Corporation launches Trunk with ABeam Consulting, surpassing 50,000 accounts

The customer, Sumitomo Mitsui Banking Corporation (SMBC), faced a historic turning point as interest rates returned. To acquire deposits, SMBC needed to target small and medium enterprises (SMEs), a segment it had insufficient experience with. The bank's legacy analog processes also made it difficult to provide the fast and convenient digital services these customers required. ABeam Consulting was engaged to support this transformation and the launch of a new service, Trunk.

ABeam Consulting provided end-to-end support from concept to launch, including market research, service design, and operational process redesign. The solution involved a complete digital overhaul, reducing account opening input fields from 200 to 70 and enabling next-business-day account opening. As a result, the Trunk service successfully opened over 50,000 accounts within its first year, achieving a strong market launch and establishing a new digital business model for SMBC.
