Background of Service Provision

Gartner predicts that spending on agent-based AI software will expand from $86.4 billion in 2025 to $206.5 billion in 2026 (a 2.4-fold increase year-on-year) and $376.3 billion in 2027 (Source: Gartner "Gartner Says Autonomous Business and AI Layoffs May Create Budget Room, but Do Not Deliver Returns" May 5, 2026). Large investments are also pouring into specialized AI agent companies, such as Harvey (valued at $11 billion) for legal services, Sierra ($15.8 billion) for customer service, and Cognition/Devin ($25 billion) for AI coding agents (based on funding rounds in 2025-2026). AI agents are entering a full-scale practical application phase.

However, many companies struggle to integrate AI tools into their operations even after implementation. They sign contracts for tools but lack the resources to incorporate them into workflows and improve operations, leading to them eventually becoming unused. The "implement and forget" approach is the biggest waste.

A primary reason for lack of adoption is the implementation of tools without designing the business flow. Without designing what triggers the AI, who confirms the output, and which system the results are written to, AI agents cannot function within an organization. Furthermore, even if Proof of Concepts (PoCs) are successful, deployment often stops before company-wide or cross-departmental rollout, with only a few individuals continuing to use the tools individually.

CRM platforms themselves, such as HubSpot's Breeze and Salesforce's Agentic CRM, are increasingly incorporating AI agents, transitioning from mere data repositories to execution platforms. With the rapid evolution of these platforms, the ability to leverage them hinges on the quality of business flow design.

As a HubSpot Elite Partner, 100 Inc. has supported numerous companies in their CRM implementations. "100 Agent Works" was developed by applying the know-how in business flow design, essential for CRM adoption, to the implementation of AI agents.

Features of "100 Agent Works"

Support begins with interviews and a business inventory. Current operations are organized to determine "what to automate, why, and in what order," before proceeding to design, implementation, and testing. Regular tuning continues after operation, updating AI agents to align with changes in business flows and organizational structures.

Routine tasks can be automated across all departments. Employees are freed from these tasks, allowing them more time to focus on work that requires human judgment, such as strategic planning, customer interaction, and creative decision-making.

Sales: Meeting minutes/thank-you email creation, CRM input, task management

Marketing: Blog outline/content creation, access analysis, competitor monitoring, social media posting

Inside Sales: Call summary, handover materials, follow-up emails

Customer Success: Initial inquiry response, churn detection, regular follow-ups

In addition to HubSpot, the service supports a wide range of tool environments including Salesforce, kintone, Notion, and Google Workspace. For companies using HubSpot, customer touchpoint data can be directly utilized as input and output for AI agents, enabling deeper automation.

Comment from Kei Tamura, Representative Director of 100 Inc.

Only 5% of corporate generative AI pilots achieve measurable results. The cause of failure lies not in the tools themselves, but in their integration into business processes. The more ambiguous the business process, the faster AI will amplify the confusion. Through implementing CRM for over 400 companies, we have been responsible for designing revenue processes and organizing data. Now that CRMs are shifting from data repositories to execution platforms, we are confident that our design capabilities can be directly applied to AI agents. 100 Agent Works is not a new service, but an extension of our existing support.

Moving forward, we will not stop at setting up agents. We will immerse ourselves in our clients' operations, designing and implementing everything from team-based agents to individual agents. By enabling humans and AI to collaborate, we aim to support our clients in achieving business outcomes beyond mere automation.
