Founder

Representative

Kazuki Tajima

After completing graduate studies at the University of Tokyo, he joined Google Japan as a new graduate in 2012. Over 13 years in the advertising sales division he drove marketing strategy for major domestic and global companies in technology, telecommunications, automotive and entertainment, managing more than JPY 10 billion in annual ad spend. In 2023 he won first place in Google's APAC internal competition.

In 2025 he joined a major venture company as CMO, overseeing more than 400 people across six divisions, building an integrated operation spanning customer acquisition, recruiting, web production and staffing, and leading company-wide generative AI adoption and cost-structure reform.

Armed with deep platform-side expertise and practical management and execution experience inside an operating company, he founded aigent LLC in May 2026. Under the mission "Rebuild the way you grow," aigent supports corporate growth end to end, from strategy through execution to in-house enablement.

Philosophy

Mission

Our Mission

Rebuild the way
you grow.

Rebuild the way companies grow

What holds back a company's growth is not people's ability but its systems: gut-feel decisions that depend on individuals, precedent followed for its own sake, and know-how that never stays in-house because everything is outsourced. We are not a company that simply executes campaigns on your behalf.

We take responsibility for the whole chain, from strategy design through production, operations and in-house enablement, and implement inside your company a system that keeps customer acquisition and recruiting running as a business.

Vision

Our Vision

A world where SMEs can compete with the same precision as large enterprises.

Enterprise-grade precision, for every small business

What to invest in, and what to stop. Making that call takes neither scale nor budget, but the right numbers and a well-constructed strategy.

We bring the marketing precision honed at large enterprises to the management decisions of small and mid-sized companies, and extend to every SME a state in which size is never a reason to hesitate.

Value

What We Value

To realize our mission and vision, these are the five standards we hold ourselves to in our daily work.

  • 01 Owner-Led The founder stays accountable to the end.

    Who does the work changes the result. The founder personally handles strategy design, proposals, creative direction and ad and social media operations, and takes responsibility for outcomes. Rather than advising as a commentator, we step into your business as the people who execute.

  • 02 True Partner Accountable for every single yen.

    The budget entrusted to us is profit your business has earned. With the mindset of an owner who wastes nothing, we make investment decisions by working backward from your break-even line and customer lifetime value. Spending the budget is never the goal, and we never propose increases without a basis.

  • 03 Fact First Decide on facts, not intuition.

    Strategy is built from search demand, customer feedback and market data. Every claim comes with evidence, and initiatives that didn't work are reported as the numbers show them. We use AI as a tool to speed up analysis and production, but people own primary research, judgment and responsibility.

  • 04 Never Done We don't build and walk away.

    For websites, ads and social media alike, launch day is only the beginning. Performance dashboards, monthly reports and improvement meetings come standard, and site, ads and social media are managed under one KPI tree. We pinpoint where to act to move the numbers, and keep moving them.

  • 05 Build to Hand Over Hand it over ready to run on its own.

    Everything outsourced, nothing learned in-house: we don't call that success. We leave the decision criteria, operating procedures and ways of reading the numbers inside your company, and our goal is a system that runs even without us. That is what rebuilding the way you grow means.
