Puente Inc. (Headquarters: Tokorozawa, Saitama; Representative: Kazuo Hoshina) has announced the launch of 'A-ko san,' an AI secretary service designed for solopreneurs and small businesses.
'A-ko san' is a new type of corporate SaaS where a dedicated AI agent handles all tasks, including business instructions, progress monitoring, approvals, and notification consolidation, entirely through natural language conversation. Puente takes on technical burdens such as server operations and Claude API management, providing a structure where the CEO can control all business operations simply by 'talking.'
■ What is 'A-ko san'?
'A-ko san' is an AI secretary service running on Puente's proprietary AI agent foundation, 'Puente Platform,' with Anthropic's Claude API at its core. It serves as the sole operational interface for the CEO, standing by 24/7 to relay instructions received via dialogue to the underlying business systems (MCP servers) for automated execution. It addresses the needs of small businesses looking to operate an 'unmanned AI company' where operations can be managed by a single person.
■ Key Features
[1] Sole Operational Interface for the CEO
Business instructions, progress tracking, and approvals are all completed through conversation with A-ko san.
[2] Puente Handles Server and AI API Management
Puente manages cloud server environments and Claude/other APIs. Customers pay a single monthly invoice, with zero technical operational burden.
[3] Multi-tenant Design with Industry-Specific Editions
Business logic is centralized in the 'Puente MCP Hub Platform' MCP servers. Following the publishing edition, editions for professional services, consulting, and e-commerce/retail will be rolled out.
[4] Dedicated Learning and Tuning
'A-ko san' learns the CEO's speech patterns, priorities, and decision-making logic. Industry dictionaries and style guides are optimized for each client.
[5] Production Ready in 3 Months
Achieved production readiness in 3 months through agile development by CEO Hoshina.
[6] Data Separation and Portability
Customer data is fully separated. Should clients wish to switch to internal operations in the future, all A-ko san prompt dictionaries and data sets are transferable.
■ Future Roadmap
Following the official release of the publishing edition in 2026, editions for professional services, consulting, and e-commerce/retail are planned to be launched sequentially by Q1 2027. The goal is to reach an ARR of 100 million yen by 2027.
