Dynagon Achieves Approximately ¥100 Million in ARR with Just One Sales Representative by Implementing PLAINER to Enable Self-Driven Customer Purchasing Experience

PLAINER Inc. (Headquarters: Meguro-ku, Tokyo; CEO: Daisuke Kobayashi; hereinafter 'the company'), provider of the product experience platform 'PLAINER,' has published a case study on Dynagon Inc. (Headquarters: Shinagawa-ku, Tokyo; CEO: Shingo Sakamoto; hereinafter 'Dynagon'), a company offering the vertical SaaS 'Smart SDS' for chemical substance management. Dynagon introduced PLAINER during its early-stage growth to design a 'self-driven customer purchasing experience' where prospects can understand the product and drive internal adoption independently. With just one dedicated sales representative, the company achieved approximately ¥100 million in Annual Recurring Revenue (ARR) within one year from near-zero post-launch, establishing a scalable growth model that does not rely on expanding the sales team.

In conjunction with the release of this case study, an online seminar will be held to deepen understanding of 'the sales process behind achieving ¥100 million ARR with one person' and 'how to effectively use PLAINER.'

Case Interview Summary

During its early growth phase, Dynagon needed to generate significant revenue quickly with only one dedicated salesperson (who also handled marketing and customer success). Despite demonstrating value in sales meetings, the company faced challenges in advancing deals because internal communication to decision-makers and relevant departments relied solely on verbal explanations from the contact person, causing delays in approvals.

To address this, Dynagon adopted PLAINER and used its 'Scenario' feature to consolidate demos, pricing tables, contract procedures, and trial information into a single URL. This enabled customers to understand the product independently and share it across their organization—creating a 'self-driven customer purchasing experience.'

As a result, Dynagon reduced sales meeting times from one hour to 30 minutes, achieved approximately ¥100 million in ARR within one year with just one salesperson, and established a lean growth model without hiring an inside sales team.

Challenges Faced by Dynagon and Results After Implementation

[Challenges]

- Needed to generate substantial revenue early on with only one dedicated salesperson (also handling marketing and CS)

- Internal sharing with decision-makers and departments relied heavily on the contact person's verbal explanations

[Actual Results]

- Achieved approximately ¥100 million in ARR within one year with one salesperson, starting from near-zero after launch

- Reduced sales meeting time from '1 hour to 30 minutes'

- Secured orders without trials (customers used PLAINER content as internal justification material)
