Growth companies are losing to competitors who've automated their marketing. We design, build, and hand over AI-powered marketing systems — with committed, measurable results.
We don't consult and leave. We identify which of these is costing you the most hours — then rebuild it on AI infrastructure.
Most growth companies have the same invisible problem: skilled people spending 30–40% of their time on repeatable tasks — reporting, content distribution, campaign setup, data pulls — that an AI system could do faster, cheaper, and more consistently.
Meanwhile, the agency bill keeps coming. The ChatGPT experiments stay in individual inboxes. And no one has connected the dots into a system.
That's what mimi63 fixes. We don't sell you a tool. We build you a working AI marketing engine — and then hand it to your team.
Start with a Diagnostic →Every engagement starts with Plan A — a diagnostic week. Then we move into the right plan for your situation.
We take over the heavy lifting — ads, content, SNS, reporting — and rebuild it on AI. Then hand it to your team.
Typical total investment: ¥350K–500K/month depending on scope. Most clients see measurable cost reduction and results improvement within 60 days.
One week. One deliverable: your top-5 AI automation wins, scored and prioritised.
Get recommended by your customers' AI agents. When AI assistants choose products for consumers, make sure yours gets picked.
These are the five patterns we see most often in 30–300 person companies. If one fits, Plan A is your first step.
The reports arrive. The invoices arrive. But no one on the team can explain the ROI — or even the methodology. Budget is leaving, capability isn't building.
Plan A → B ¥350K/moAI experiments are happening individually, across Slack threads and private tabs. No brand consistency. No compounding. No institutional knowledge being built.
Plan A → B ¥400K/moAI agents are becoming personal shoppers, advisors, and decision-makers for consumers. If your brand isn't optimized for AI recommendation, you're losing sales you never even see.
Plan A → C ¥200K/moThe goal is internal capability — not permanent vendor dependency. You want a system your team can own and run, not a retainer that creates lock-in.
Plan A → B ¥500K/moAI content doesn't have to mean generic content. Brand voice, aesthetic consistency, and tone guardrails are built into the system architecture from day one — not added as an afterthought.
Plan A → B ¥450K/moMost AI consultants hand you a report. Most agencies keep you dependent. mimi63 sits in the gap: we build the system, we prove it works, and then we hand it to your team.
The outcome isn't a deliverable. It's organisational capability — your marketing running on AI rails, owned by your people, with lower costs and stronger results.
A structured four-step process designed to build internal capability — not create dependency.
We map your current marketing workflows, identify every repeatable task, and score the AI automation potential of each one. You get a prioritised list of the top-5 wins — with estimated hours saved and cost reduction.
Week 1We design your custom AI marketing system: which tools, which workflows, how they connect, and what the handover looks like. Brand voice and quality guardrails are built into the architecture.
Week 2–3We build it, launch it, and run the first iteration alongside your team. We test, measure, and iterate until the system is producing consistent results. Cost and performance tracking begins.
Month 1–2We train your team, document everything, and step back. You own the system. Optional retainer available if you want us on call — but the goal is your independence, not our lock-in.
Month 3+Plan A diagnostic starts at ¥80,000 — one week, five prioritised AI wins.
