株式会社サイド・バイ・サイド is a Japanese company founded in 2010. It positions itself as a service provider centered on direct marketing, supporting the sale of products such as beauty items, cosmetics, and health foods. Its website emphasizes connecting companies with consumers and building trust through the stories, concepts, worldview, and experiential value behind products.
Its services cover brand and product storytelling, product planning, promotional planning, talent and organizational training, and other forms of support. In product planning, it handles product concepts, key messaging angles, dosage/form-factor and functional ingredient proposals, coordination with OEM manufacturers, cost control, and prototype monitoring/testing evaluation. Its marketing support is divided into acquisition and retention: on the acquisition side, it supports business planning, sales flows, ad creative/performance testing, first-purchase inserts, F2 measures, and subscription mechanisms; on the retention side, it supports CRM tool selection, promotional planning, cross-selling, PR/workshops, LTV validation, and issue identification.
The official website does not disclose packages, pricing, project timelines, or billing methods. It appears to operate mainly through customized consulting and execution support. Contact options include email, phone, and fax, so interested clients would likely need to discuss their requirements to obtain a proposal. The site does not mention a free trial, nor does it disclose any directly usable SaaS platform or admin backend.
Its strengths are a clear industry focus and a relatively complete service chain around product development, customer acquisition, CRM, and organizational training for beauty and health DTC/direct sales businesses. It also places strong emphasis on storytelling and empathy-driven marketing, making it suitable for teams that want to improve brand narrative and repeat-purchase operations. The downside is that publicly available information is limited: there is a lack of detailed case studies, data sources and scale, channel performance results, technical integration details, and service SLA descriptions. Further interviews and validation would be needed before making a decision.
It is best suited to brands selling cosmetics and health foods in the Japanese market, especially teams planning new product development, subscription purchases, CRM retention, or TV shopping/telemarketing channels. Access from China cannot be confirmed from the available content, so it should be considered unknown. Cross-border companies should also pay attention to language communication, local Japanese payment and settlement, advertising compliance, and alternative local DTC growth agencies or CRM service providers.
