The021株式会社 is an AI-first HubSpot partner specializing in Sales Hub, Service Hub, and Marketing Hub, serving B2B SaaS companies across the US and Japan. Where most partners stop at configuration, we go further by combining native HubSpot AI with Claude-powered workflows to build intelligent revenue systems that surface risk, flag opportunities, and route intelligence to the right person automatically. We use the right AI tool for the right job, whether that's HubSpot's built-in AI features or custom Claude integrations where they create the most leverage. Every engagement starts with your business outcomes, not your tool configuration... and we stay involved until your team can run it independently. Boutique practice. Senior expertise on every project. Direct communication, no account managers. Bilingual support across US and Japan markets.
