Business (description what they do)

Provision and sales of marketing tools "Mico Engage AI", "Micomii" and "Mico Voice AI".

We will be Asia's No.1 BtoC Communication Platform!

Our mission is to "Empower every brand for a better future" and our medium-long-term vision is to "To be No.1 BtoC Communication platform in Asia”. There are still many challenges in the BtoC domain to acquire attribute and behavioral data of each customer and realize communication that satisfies each customer. Until now, segmentation has been done in such a way as "men in 20s" or "those who have purchased a product at least once". However, this method includes people with completely different interests in the same category, resulting in a large number of unsolicited messages being delivered to many customers. In addition, people's interests and the environment surrounding them change from moment to moment. Instead of responding to customers based on information obtained in the past, communication must be tailored to the customer's "What do they want to do now? While communication channels are diversifying, many companies still communicate only by e-mail or telephone. In the future, companies will be required to deliver messages by flexibly changing channels according to the customer's situation, rather than relying on a specific communication method. In response to such a society, we must ask ourselves, "What are our customers doing right now? This is the basis for true personalization that provides the necessary information through the most appropriate channel based on real-time data such as "What are customers doing right now?

We have talented members from diverse backgrounds!

The company is an environment where 80% of employees are mid-career, and many members come from major consulting firms, major mobile carriers companies, general trading companies, and other companies listed on the first section of the Tokyo Stock Exchange. We have a wide age range, mainly in their 30s, and respect the diversity of nationalities, not only Japanese but also foreign nationals. ★Real opinions from IT Engineers at Mico,Inc.★ “Because there are still so few engineers, there are active efforts (workshops, off-site meetings, culture boards, etc.) to value engineers and foster a good environment and culture." “Communication with the Biz side is also very active, and there are no walls between the product side and the Biz side, as is often the case. I feel that we have a well-coordinated organization.” “Opportunities to work in an environment actively striving to become Asia's No. 1 are rare, so we would love for individuals who are eager to take on big challenges to join us.”

We have raised a cumulative total of about 6.3 billion yen!

Mico Raises 3.5 Billion Yen in Series B Funding Mico has secured 3.5 billion yen in Series B funding, led by Vertex Growth with participation from JAFCO Group, Mitsubishi UFJ Capital, SMBC Venture Capital, Mizuho Capital, and existing investors ALL STAR SAAS FUND and Eight Roads Ventures Japan. With this round, our total funding now exceeds 6.3 billion yen. Moving forward, we will accelerate product development for global expansion and strengthen our organization in line with our 2030 vision to become "Asia’s No.1 Brand Empowerment Company." ★ Investor Comments ★ Vertex Growth General Partner, TAM Hock Chuan "We are pleased to lead Mico’ Series B round alongside top investors. Mico’ scalable platform, deeply integrated with LINE, enables personalized customer engagement and delivers immense value. We admire CEO Yamada’s strong vision and top-tier management team and are excited to support Mico' global growth with our expertise and best practices." JAFCO Group, West Japan Branch Head & Partner, Mizuki Takahara "I first met CEO Yamada four years ago, before Mico Engage AI’s launch, when Mico had fewer than 30 employees. I was impressed by his bold vision to build 'Asia’s No.1 company.' Since then, his determination has led to Mico Engage AI’s rapid growth and a team of over 100 talented members. Inspired by their journey, we are honored to invest and support Mico in its ambitious challenge."
