Our growth engine

From One Seed
to Orbit.

Four stages on one line — from the app store to new markets.

  1. Stage 01 · Seed

    Plant the seed with ASO Index.

    It all starts in the store. ASO Index reads Japanese and Korean keywords by morpheme, and we localize your listing, creatives and messaging so your app takes root in a new market.

    • ASO
    • Localization
    • Market research
  2. Stage 02 · Growth

    Focus everything on growth.

    Once the roots hold, we solve whatever is holding growth back — user acquisition, influencer campaigns and PR, run as one plan aimed at your North Star Metric.

    • User acquisition
    • Influencers
    • PR
  3. Stage 03 · Expansion

    Harvest, then expand.

    Growth turns into results you can collect. Then we build the brand around them — influencer partnerships, branding and community — and carry it into new markets.

    • Influencer partnerships
    • Branding
    • New markets
  4. Stage 04 · Rocket Ads

    Launch further with Rocket Ads.

    When the playbook is proven, Rocket Ads takes it further — engagement ads on local reward media in Japan and Korea.
