Analog PR, which specializes in "designing corporate information and image" using a unique marketing strategy that blends media, web, and offline channels, announces the launch of its new company, Soushinsha Inc. Founded by Keisuke Matsuura, the company will partner with Tatsuo Oyama, a founder known for his YouTube channel "Marketing Samurai" with over 100,000 subscribers. By merging Matsuura's PR capabilities, responsible for hundreds of successful media exposures, with Oyama's marketing strength, boasting a track record of producing YouTube channels with over 96 million total subscribers, Soushinsha aims to develop "business production that directly leads to sales," not just simple awareness expansion.

The company name "創進舎" (Soushinsha) embodies the desire to be a group that "creates" the future and constantly "advances," and a "learning house" where management professionals can grow together. By breaking down the barriers between PR and marketing and updating businesses from their core, Soushinsha will support sustainable corporate growth. Soushinsha offers "PR that can be quantified by numbers," moving beyond qualitative PR, by providing services that pursue ROI, visualizing effects through metrics such as reach and new visitors in the awareness stage, measuring interest through viewing time and retention rates in the interest stage, tracking secondary actions and quote requests to measure lead conversion rates in the consideration stage, and presenting ROI calculated from the correlation between exposure periods and sales in the purchase stage. Representative Director Keisuke Matsuura of Analog PR, who has handled new business and PR for major media outlets including the Fufisankei Group, develops P2C brands and SNS marketing using a unique method combining PR and business development. He has supported business growth in the PR and media domain with over hundreds of achievements, personally securing 350 million yen in 4 months as a solo salesperson, rebuilding businesses without relying on investments or loans, and achieving 1.4 billion yen in group sales for two consecutive fiscal years.
