The LinkedIn post highlights a focus on in-house engineering capabilities, pointing readers to a technical blog from Slash’s founding engineer describing how its card transaction processing system was built and scaled. For investors, the reported volume growth and emphasis on proprietary infrastructure may suggest rising customer adoption, potential revenue expansion tied to interchange and membership fees, and a strengthening competitive position in the corporate card and B2B payments segment.
