TieUps Launches 'Rittolink Collaboration DB' Categorizing 4 Million Creators into 273 Segments

TieUps Inc. (Headquarters: Meguro-ku, Tokyo; Representative Director: Fumihiro Ohara; hereinafter referred to as 'Our Company'), which develops co-creation and collaboration businesses centered on creator data, has begun offering the 'Rittolink Collaboration DB'. This service utilizes user data accumulated over five years on the branding profile tool 'lit.link'.

The service classifies over 4 million creators into 21 categories and 273 segments, supporting everything from planning and audience acquisition to campaign execution and reporting, including targeted announcements for specific genres, KOL casting and diffusion measures, and long-term engagement using communities.

## Background
The influencer marketing market is expected to reach 86 billion yen in 2024 (116% year-on-year) and grow to 164.5 billion yen by 2029 (※1). Meanwhile, challenges for marketing professionals are also becoming more severe, with 40% of companies reporting 'difficulty in measuring effectiveness' and 30% stating 'difficulty in selecting influencers suitable for their company' (※2).

The fundamental issue lies in the reality that 'follower count' is still used as the primary metric. However, mega-influencers with over 1 million followers have an engagement rate of only 1.21%, less than one-third of micro-influencers with 10,000 to 100,000 followers (※3). The era where the precision of 'who is reached' rather than scale determines results has begun.

Furthermore, changes in consumer behavior, particularly among Gen Z, are evident. Purchases are increasingly driven by 'Kaiwai' (communities formed around specific hobbies, values, and cultures). From VTubers to fitness, 'Oshi-katsu' (passion-based fandom), gadgets, and local regions, highly engaged fan bases exist within these fragmented communities. The 'Oshi-katsu' population is projected to reach approximately 19.4 million by 2025 (about 16% of Japan's population), with each person spending an estimated 210,000 to 250,000 yen annually (※4).

In response to these market shifts, Our Company has been working to build a marketing infrastructure that enables 'accurate and continuous approach to creators in desired genres,' starting with the 5-year accumulation of 4 million profile data points on lit.link.

## What is Rittolink Collaboration DB?
'Rittolink Collaboration DB' is one of Japan's largest creator databases, built from the profile information of creators registered on lit.link.

Its biggest feature is enabling reach to creators on a 'hobby, interest, and cultural sphere (Kaiwai) unit' basis, rather than a traditional follower count.

* Total Creators: Over 4 million (as of March 2026)
* Genre Classification: VTuber / Beauty & Cosmetics / Fashion / Fitness / Gourmet & Cooking / Travel & Outdoors / Games / Music / Anime & Manga / Business & Career / Technology & IT, among others, totaling 21 categories and 273 segments.
* Internal support for over 10,000 detailed segments.

Companies and advertising agencies can specify genres and precision (40% or more to perfect match) to check estimated reach and narrow down target creators.

## 3 Service Menus
This service provides consistent support across the three phases of creator marketing.

【1. Announcement | Segmented Distribution】
Effectively reach creators in specific genres through various methods such as banner distribution, LINE push notifications, and short videos. Achieves highly accurate targeting based on activity genre and context, independent of follower counts.

【2. Diffusion | Casting & Contests】
Implement PR by casting KOLs and influencers from specific segments. Furthermore, launch diffusion-type contests involving a large number of creators to foster organic awareness expansion originating from word-of-mouth within the genre.

【3. Engagement | Community Management】
Utilize a proprietary community system to build long-term relationships with creators through surveys, interviews, and co-creation PR. Support extends beyond one-off campaigns to brand ambassadorship.

Our Company offers a one-stop system that supports these three phases of campaigns, from planning and creator selection to audience acquisition, campaign execution, and performance reporting.

## Future Outlook
With the Vision 'Into a world where you can take a step forward without realizing it,' Our Company has been working to create mechanisms for individual activities to spread naturally.

Starting with Rittolink Collaboration DB, we will accelerate the construction of an infrastructure where creators and companies can connect appropriately by advancing more sophisticated segmentation and integration with advertising and products. By establishing an environment where diverse individual activities are correctly evaluated and lead to opportunities, we will contribute to the further development of the creator economy.
