産業を越えた業務効率化に挑む、マルチバーティカルSaaS―アトミックソフトウェアの思想―

Atomic Software CEO Shoichi Hatanaka and CTO Ryusuke Kumita explain how they are building a multi-vertical SaaS empire across aesthetics clinics and security firms using a modular ‘atomic’ architecture.

• Atomic Software (rebranded from MedicalForce in Jan 2025) targets industries where DX has not yet penetrated, starting with aesthetic clinics and security firms.
• The ‘Atomic Software’ concept treats each product feature as an independent module; combinations of modules form industry-specific all-in-one SaaS products.
• PMF accelerator: engineers physically embed at client sites to experience operations firsthand before building — one engineer stayed at a Kyoto clinic for days.
• Hatanaka defines PMF as minimizing ‘activation energy’ during switching: reduce what stops working in the old workflow, not just showcase gains in the new one.
• Salary calculation module built for the security product is planned for reuse across medical and future verticals, compounding the module asset library over time.
• On AI: the core job remains automating what customers find painful; SaaS will gradually shift toward agents, but the question to answer stays the same.
• Key hiring gaps named: VP-level mini-CEOs per vertical, M&A/finance capability to accelerate new vertical entry, and strong sales talent to quickly isolate product vs. market failure.
• Hiring screen: candidates draw a ‘life motivation curve’ and interviewers assess the energy level of their peak-motivation moments, not just skills or commitment signals.
