Company profile

researched Aug 2026

KKday is a Taipei-headquartered online travel e-commerce platform that connects independent travellers with local experiences, tours, activities and attraction tickets. Founded in 2014 by Ming Chen, the company began with a focus on curated local experiences in the Asia-Pacific region and has since broadened into an all-in-one travel booking service that also covers hotels, rental cars, flights, SIM cards and eSIMs, rail passes, dining reservations and event tickets. As of late 2024 the platform listed more than 350,000 experiences across over 550 cities in 92 countries.

Beyond the consumer marketplace, KKday operates several related brands. Rezio, launched in 2019, is a cloud-based SaaS booking management system for tour operators, activity providers and attractions, offering inventory tracking, reservation management, voucher scanning via a mobile app, channel management, analytics and integrations with OTAs and payment providers; it supports over 5,000 merchants, 30,000 experiences and 10 million travellers, with a deployment at the Nikko Toshogu Shrine used to manage queues through online booking and cashless payment. FineDayClub, launched in late 2020, is a membership-based travel concierge service for high-end clients, families and organizations. Activity Japan, a Japanese domestic experience booking site acquired in 2021, continues to operate independently.

The company employed 960 staff in 2025 and is led by founder and CEO Ming Chen, with Victor Tseng listed as CFO.

Founding story

Ming Chen launched KKday in 2014 after building two prior travel ventures, Star Travel and Ezfly, both of which he led to IPO. The platform was created to let travellers choose from thousands of curated local experiences across multiple countries. The KKday name was selected by Chen and his team for its memorability across users speaking different languages.

Business model

KKday operates a two-sided travel marketplace: it aggregates inventory from local tour operators, attractions and activity suppliers and sells it to travellers through its website and app, earning commissions on bookings. Alongside this consumer OTA business it runs Rezio, a B2B SaaS booking and inventory management product sold to suppliers, which focuses on backend operations and lets merchants retain brand independence and direct customer relationships while optionally distributing through OTAs including KKday. FineDayClub adds a membership-based concierge model for premium customers.

Revenue comes primarily from commissions on experience, ticket and travel-service bookings made through its consumer marketplace, supplemented by SaaS revenue from Rezio subscriptions for tour operators and attractions, and membership-based concierge services through FineDayClub. Reported revenue doubled year on year in 2022, surpassing pre-COVID levels.

Traction

Inventory grew from about 6,000 experiences in 53 countries in 2016 to over 10,000 in more than 500 cities and 80 countries by 2018, and more than 350,000 experiences in 92 countries by late 2024. By the end of 2018 the company reported over 4 million weekly website views and more than 1 million app downloads with roughly 400 employees, rising to 960 employees in 2025. Revenue doubled in 2022 versus 2021, exceeding pre-pandemic levels, and European product sales in the first three quarters of 2023 ran 60% above the same period in 2019. Vietnam bookings rose 2,000% through 2022 and Rezio onboarded over 1,200 operators in the country; Rezio overall supports more than 5,000 merchants and 10 million travellers.

Latest developments

In December 2024 KKday announced a $70 million round led by Cool Japan Fund, Taiwan's National Development Fund and Darwin Ventures, earmarked for mergers and acquisitions, talent, AI innovation, strengthening its Asia-Pacific position, improving its Japan offering and supporting small suppliers in Southeast Asia through Rezio. In July 2025 CNN's 'Next Stop' programme visited the company's Taipei headquarters in a segment on Taiwan travel. The platform continues to publish destination content and promotions, including extensive Japan inventory such as theme park tickets, observation decks, day tours and eSIM products.

β–ΈFull profile β€” market position, technology, go-to-market, geography, history, risks & controversies

Market position

KKday is described as a Taiwan-based travel experiences platform and a key player in Taiwan and across Asia, having remained operating through the COVID-19 period when many travel-tech companies shut down or scaled back sharply. Coverage positions it within the growing experiences and activities segment of online travel, with an Asia-Pacific focus and stated ambitions for global expansion.

The company combines a consumer experiences marketplace with supplier-facing software: Rezio addresses backend operations for tour and attraction operators, allowing them to digitize offline processes and keep direct customer relationships, in contrast to the commission-based OTA exposure that KKday itself provides. Its portfolio also spans luxury concierge (FineDayClub) and a Japan-focused domestic experience site (Activity Japan), and it positions the main platform as an all-in-one travel app spanning hotels, cars, flights, SIM cards, rail passes, dining and tickets.

Technology

The consumer platform is a web and mobile e-commerce marketplace with booking, ticketing and voucher functionality. Rezio is a cloud-based SaaS system offering inventory tracking, reservation management, a mobile app for order management, customer information checks and voucher scanning, channel management, customer analytics and integrations with multiple OTAs and payment providers. The company has stated plans to invest funding in artificial intelligence integration.

Go-to-market

The company acquires travellers through its consumer website and mobile app, supported by destination content, travel guides and promotional campaigns, and recruits supply through direct merchant onboarding and the KKday Marketplace programme in Southeast Asia. Distribution partnerships extend inventory, including Rail Europe for European rail and Tabelog for Japanese restaurant reservations, while Rezio serves as a supplier-side channel that digitizes offline operators and can connect them into the marketplace.

Independent leisure travellers booking tours, activities, attraction tickets, transport and connectivity products, particularly in Asia-Pacific markets; high-net-worth customers, families and organizations for the FineDayClub concierge service; and tour operators, activity providers and attractions as Rezio software customers.

Geography

Headquartered in Taipei, Taiwan, with early offices in Hong Kong, Japan, South Korea and Singapore, later expansion into Malaysia, Thailand, Vietnam, the Philippines, Indonesia and mainland China. The platform sells experiences in 92 countries and over 550 cities, with core markets historically in Taiwan, Hong Kong, South Korea and Japan, and growing coverage of Europe through the Rail Europe partnership.

History

KKday was founded in 2014 in Taipei by Ming Chen, who had previously started and led Star Travel and Ezfly to IPO. A US$4.5 million Series A led by AppWorks Ventures in March 2016 funded office openings in Hong Kong, Japan, South Korea and Singapore, and by end-2016 the platform listed over 6,000 experiences across 53 countries and 174 cities. Expansion into Malaysia, Thailand, Vietnam and the Philippines followed in 2017-2018, alongside new offices in Indonesia and mainland China; a $10.5 million round led by Japanese travel group H.I.S. closed in February 2018. By the end of 2018 the company operated in 11 countries and regions with roughly 400 staff. The Japan-South Korea trade dispute and the COVID-19 pandemic prompted a pivot to domestic staycations and local experiences; KKday raised a $70 million Series C in 2020 that was later extended to $95 million with a TGVest Capital-led $20 million addition in July 2022. It acquired Activity Japan in 2021, signed a rail distribution MoU with Rail Europe in 2023, and closed a $70 million Series D in late 2024, bringing total capital raised to over $250 million.

Risks & controversies

The business is exposed to travel demand shocks, as demonstrated when the COVID-19 pandemic wiped out roughly 90% of regional travel and forced full customer refunds and a pivot to domestic products, and by the Japan-South Korea trade dispute that redirected regional tourist flows. Management has also flagged staffing shortages across Asia's tourism industry as demand rebounded.
