hak-i is an AI-native marketing company based in Tokyo. We build growth systems where generative AI, autonomous agents, and human strategy compound.
Three structural shifts are happening at once. Companies that rebuild their marketing around AI now will compound an advantage that late movers cannot buy back.
Customers increasingly ask ChatGPT, Perplexity, and AI Overviews instead of searching and clicking. Being cited by AI assistants is becoming as important as ranking on Google.
3.5×growth of AI search usage in Japan in 11 months — now 37% of consumersGenerative AI has pushed the marginal cost of ad creative toward zero. The winners are no longer the teams with the biggest studios — they're the teams that test the most iterations per week.
87%of marketers now run generative AI in an always-on workflowBidding, budget allocation, and anomaly detection are shifting from dashboards to autonomous AI agents that watch accounts 24/7 — freeing humans for strategy.
+32% CTRfrom AI-driven dynamic creative optimization vs. static campaignsOur services are the state of the art of AI marketing itself — not AI as a garnish, but AI as the operating system of growth.
High-volume generation and testing of ad creative — static, video, and copy — powered by generative AI. Pre-flight AI scoring predicts the winners before budget is spent, and performance data feeds the next generation loop.
AI agents monitor bidding, budgets, and anomalies across Meta, Google, and TikTok around the clock. Human strategists make the decisions that matter; agents handle everything else.
Structuring your brand to be found, trusted, and cited by AI assistants — ChatGPT, Perplexity, Gemini, and Google AI Overviews. The next SEO, before your competitors get there.
LLM-powered analysis of user behavior, landing page personalization, and continuous conversion experiments — turning the same traffic into more revenue.
Machine-learning models for LTV prediction, audience scoring, and budget allocation — so acquisition targets are set by science, not by gut feel.
We embed AI workflows inside your marketing organization — tooling, playbooks, and training — so the capability stays with you, not just with us.
Every engagement runs as a weekly learning loop — the same iteration speed that frontier AI companies use to build products, applied to your growth.
We map your funnel, data, and current operations to find where AI creates the most leverage first.
We architect the growth system — channels, creative engine, measurement, and agent workflows.
Campaigns, creative loops, and AI agents go live. First results within weeks, not quarters.
Weekly iteration on data. Every experiment makes the next one smarter — that's the moat.
