What Cubic does

Cubic is a Tokyo-headquartered digital marketing agency and SaaS provider founded in June 2016 by Koike Toru (小池 徹), a former DeNA sales and new-business executive. The company operates a two-pillar business: (1) advertising agency services (広告代理事業) providing digital advertising strategy, social media operations, creative production, and in-house marketing consulting; and (2) the Rakusta (ラクスタ) product suite of Twitter/X-focused campaign tools. Named enterprise clients are concentrated in Japanese mobile game publishing (NextNinja, KLab, VOYAGE SYNC GAMES, IGG Japan, Imaginer, Zest/Dream Artisan) and adjacent media verticals (NTT Docomo's Conobie parenting media, Osaka Gas Marketing, TOHO Games), with documented campaign outcomes including 250K follower growth and 500K pre-registrations for Touhou LostWord, Twitter trending #1 for 夢職人と忘れじの黒い妖精, and 30–50% CPI reductions for VOYAGE SYNC GAMES.

The Rakusta product line is the company's technology backbone. Rakusta (released December 2022) is a Twitter/X-specialized instant-win campaign tool with digital gift auto-distribution, multiple participation conditions (follow, retweet, hashtag, keyword, URL click), reminder functions, and web-transition campaign architecture. Rakusta Lite (July 2023) is a lower-cost entry product starting at 50,000 yen enabling next-day campaign launch with DM bulk-sending for 100+ winners. Rakusta LP100 (June 2025) is an SNS-linked landing page service offering 100+ templates (diagnostics, omikuji, puzzles, slots, scratch cards) starting at 500,000 yen with one-week minimum delivery, now supporting X, LINE, Instagram, and TikTok. The platform is built on a direct Twitter API Enterprise Plan contract (signed June 2023, following Twitter's API monetization), integrating with giftee for 500+ digital gift options, and includes ROBOTICA, a Twitter ad auto-operation tool developed in-house.

Cubic generates revenue through three streams: (1) professional services fees from its advertising agency engagements, which is described as the core revenue driver funding product reinvestment; (2) subscription/transactional SaaS fees from the Rakusta product suite with published unit pricing (Rakusta Lite from ¥50,000, LP100 from ¥500,000); and (3) bundled pre-registration campaign packages for the game app market priced at ¥1.4M–¥2.0M. Distribution is direct-sales led through a field sales team (inside sales plus outside new-customer acquisition), with a self-serve PLG motion layered on for Rakusta Lite targeting SMBs. The company is self-funded, has 39 employees as of July 2025, and has not taken external VC capital.
