Genesia Ventures Makes Additional investment in TAIAN, an AI-Powered Platform for the Celebration Market
Genesia Ventures has made an additional investment in TAIAN from Genesia Venture Fund 3 (GV-3) as part of its Series B round. TAIAN provides AI products and services specializing in the “Celebration Market.”
Investment Background
The spread of the internet, social media, and AI has created an environment in which people can live more independently as individuals. At the same time, the value of real-world experiences where people gather and connect emotionally is becoming greater than ever. TAIAN defines spaces where positive energy is created through these gatherings as “celebrations,” and has built a unique data foundation by improving on-site productivity and supporting management in the wedding and banquet domains.
Genesia Ventures has supported the team’s journey since the seed stage. As we continued to accompany TAIAN’s strong business progress after its Series A, our conviction deepened in the company’s potential to evolve into a Celebration Platform powered by AI agents and built on the wedding and banquet data it has accumulated. This additional investment in the Series B round is a renewed demonstration of that conviction.
Business Overview
With its vision of “moving the world through celebrations,” TAIAN is a startup developing multiple products for the approximately JPY20 trillion Celebration Market, spanning bridal, events, hotels, restaurants, gifts, and more.
Its core product — All-in-One Wedding and Banquet System Oiwaii — is a cloud-based wedding and banquet system used by 400 wedding venues and approximately 1,100 partner vendors across Japan. It centrally manages everything from customer information, estimates and ordering, to relationship-building after ceremonies, and is equipped with AI-powered features for operational efficiency and decision-making support.
Canjii, its banquet organizer agent, is an AI-powered venue-matching and event execution support service. As of the end of June 2026, the number of affiliated venues nationwide had surpassed 700.
Concept Marry, its web invitation and seating chart service, provides RSVP management, online gift money payments, smart reception, and seating chart creation, and is used by approximately 600,000 users annually.
In addition, TAIAN offers an inbound wedding support service that provides end-to-end support from customer acquisition design for overseas couples to day-of-event operations, accelerating its full-scale approach to the global Celebration Market.
Use of Funds and Future Outlook
The newly raised funds will be used in the following areas:
- Strengthening the organizational structure of its core wedding and banquet business and expanding domestic market share
- Investing in the banquet platform business
- Expanding services for complex facilities, including hotels and restaurants
- Full-scale development of its inbound-focused business
By establishing a vertical data foundation accumulated across each business and leveraging AI agents powered by that data, TAIAN aims to evolve into a Celebration Platform that delivers optimal experiences for diverse needs, and to drive further growth in the Celebration Market from Japan to the world.
About the investment

Since TAIAN’s Series A approximately two years ago, we have had the privilege of accompanying the team’s strong business progress. Through that journey, our conviction in the company’s potential for further nonlinear growth has deepened, and we are grateful for the opportunity to make our fourth investment in TAIAN.
It has been about four years since our initial seed-stage investment, and we feel a special sense of purpose in supporting services that help create celebrations for more people.
