What Increments does

Increments (operating commercially as Qiita Inc. / Qiita株式会社) operates Japan's largest developer knowledge-sharing community and an adjacent enterprise knowledge management product. The company was founded in 2012 and is headquartered in Nagoya, Japan, with corporate registration as a Japanese corporation (address: Nakamura-ku, Meieki, Nagoya Station Building 32F). It is a consolidated subsidiary of Ateam Holdings Inc. (株式会社エイチームホールディングス, TSE Prime: 3662), providing it with parent-company capital access and listing-segment governance discipline. Leadership is comprised of founder & CEO Hiroshige Umino and Chairman Hironari Umino.

The company's product surface is two-sided and built on a shared knowledge-sharing infrastructure. "Qiita" (キータ) is the public, free community platform where individual engineers record, share, and discover technical articles on software development and adjacent topics; it is the dominant Japanese-language venue in its category and underpins large-scale annual community events such as the 16th-edition Qiita Advent Calendar (10,000+ participants and 23,000+ articles in 2025) and the Qiita Conference (7,000+ registrants). "Qiita Team" (キータチーム) is the paid, internal counterpart, an enterprise subscription product for organizational knowledge capture and team collaboration, with documented deployments including FREAKOUT BACKTARD. An additional line, "Kobito," is a Mac-based note-taking app targeted at developers.

The business model combines a free, ad-supported consumer/community product (Qiita) with a paid B2B subscription product (Qiita Team). Revenue is generated through (i) recurring Qiita Team subscriptions sold to engineering organizations for internal knowledge management, and (ii) advertising placement via the Qiita business site (business.qiita.com), including event sponsorships on the Advent Calendar and Conference. Pricing is not publicly disclosed. Distribution is self-serve/web-based through qiita.com and teams.qiita.com, with primary marketing executed through community events, the weekly "Qiita FM" podcast, and corporate web presence; no reseller or third-party channel infrastructure is evident. The company competes largely in a Japanese language silo, with global web access but no disclosed non-Japan commercialization.

Core offering

Increments (operating as Qiita Inc.) builds and operates developer knowledge-sharing software products. Its flagship offering is Qiita, a free public platform where software engineers record and share technical knowledge through articles. Its commercial offering is Qiita Team, a paid SaaS collaboration tool that lets organizations capture, document, and share internal engineering knowledge among team members. The company also monetizes an advertising channel through its Qiita Business site and runs community events such as Qiita Advent Calendar and Qiita Conference.

Product overview

Increments (Qiita株式会社) operates a dual-product platform centered around developer knowledge sharing. The flagship product Qiita is a public community platform where engineers share technical articles, while Qiita Team is a private, team-focused version for internal knowledge management. Both products share the same underlying knowledge-sharing infrastructure but serve different collaboration contexts — Qiita for public community engagement and Qiita Team for private team collaboration.

Increments competitors and assessment

Company assessment

Direct peers

Hashnode: Developer-first blogging and knowledge community with team workspaces. Comparable to Qiita in combining public dev publishing with a paid internal knowledge product, though globally distributed.
note: Major Japanese content publishing platform with a strong technical-creator user base. Comparable to Qiita as a Japan-centric knowledge-publishing destination, with a paid membership model analogous to Qiita Team.
Stack Overflow: Global Q&A platform for software developers. Closest international analog to Qiita's public community offering, with a paid enterprise tier (Stack Overflow for Teams) that parallels Qiita Team's value proposition.
Zenn: Japanese developer knowledge-sharing and blogging community owned by Cerezo. Most direct competitor to Qiita, targeting the same Japanese engineer audience with articles, books, and similar community events.
dev.to: Open developer community for sharing articles and tutorials. Mirrors Qiita's public community + ad-supported model, though English-first and without an enterprise team offering.

Emerging players

Notion: Team knowledge management and wiki product. Competes with Qiita Team for internal engineering documentation and structured knowledge bases, especially with globally distributed teams.

Broad incumbents

Confluence (Atlassian): Enterprise team wiki and documentation platform bundled into the Atlassian developer suite. Direct competitor to Qiita Team in Japanese engineering organizations already standardized on Jira/Atlassian.
Medium: Large-scale open publishing platform serving creators broadly, including developers. Comparable as an ad-supported article platform, though not developer-specialized and globally oriented.
GitHub Discussions: GitHub's built-in community Q&A and discussion features inside its dominant code-hosting platform. Indirect substitute for Qiita's public community, especially for open-source and global teams.

Regional players

Hatena (Bookmark / Blog): Long-standing Japanese blogging and bookmarking platform with strong tech-community roots. Regional alternative to Qiita for Japanese knowledge publishing, though with declining dev mindshare.
