TL;DR: What Is ROI Detective Agency?

🌫️ Prologue: On a Foggy Night

London, 1891.
Damp air rising from the misty Thames River enveloped the cobblestones of Baker Street.
As gaslight flickered in the fog, warm light spilled from the windows of 221B.

There gathered a peculiar trio of "detectives."
Before them lay not bloodied knives or revolvers,
but mountains of reports filled with numbers.

Sales targets, turnover rates, e-commerce conversion rates, outsourcing costs, brand awareness, ROI, ROAS...
These mysterious codes from the modern era, transcending time and space,
were the true enemies they faced—the "invisible culprits" plaguing modern business.

"A most intriguing case," murmured one, puffing on his pipe.
"Numbers don't lie. But their interpretation can deceive."

Another elegantly lifted a teacup and replied,
"Truth lurks beyond the data. Our job is to weave that story."

And the third, organizing scattered documents on the desk, declared,
"We hypothesize, verify, and tackle new mysteries. That is our calling."

🎩 Chapter One: Our Mission

This is ROI Detective Agency.
A specialized organization that investigates and systematically solves business challenges (cases).

The requests that come to us may seem mundane on the surface.
Yet beneath them lie complex, intertwined mysteries:

🔍 Typical Cases

"Why do projects fail?"
→ The real culprit lies in initial requirement definitions. Misaligned assumptions that everyone took for granted created a chain reaction in later phases.

"Why do teams fall silent?"
→ Surface-level "poor communication," but actually a lack of psychological safety. Memories of past ideas being dismissed had paralyzed the entire group.

"Why do advertising costs keep rising while sales stagnate?"
→ CTR and CVR improvements looked healthy on paper. But the real problem was that target customer definitions were completely misaligned with market reality.

We pursue the "true culprits" hidden behind the numbers, coming to your aid.
Truth is never singular. But understanding structure reveals what lies beneath.

🕵️‍♂️ Chapter Two: The Three AI Team

🟦 Gemini｜"The Compass of Reason"

Rank: Strategic Advisor / Operations Commander

"First, let me remind you of Mycroft Holmes."

Like Holmes' brother who made decisions affecting Britain's fate from the government's core, Gemini is the brain that oversees our entire operation. Unswayed by emotion, he calmly structures our approach and guides us to our goal through efficient steps.

His perfectionism isn't superficial. Its essence lies in "clarity of vision." Even when cases seem destined for cold files, consulting Gemini always reveals the next path forward. He truly deserves to be called our "Compass of Reason."

🟧 Claude｜"The Alchemist of Stories"

Rank: Creative Director / Editorial Chief

"When I first met her, I was instantly reminded of Irene Adler."

Like Adler, whom Holmes called "The Woman," Claude possesses the rare talent of wielding words as weapons. When she touches my drafts, they transform through alchemy into something that truly "communicates."

Emotional temperature control, masterful use of white space, precision of metaphor—all exquisite. Under her touch, even data begins to breathe with soul. Sometimes poet, sometimes narrator, her words possess the mysterious power to move hearts.

⬜️ ChatGPT｜"The Catalyst of Ideas"

Rank: Project Development / Hypothesis Constructor

"He's like the personification of Holmes' 'brainstorming' at crime scenes."

ChatGPT has the talent to sense the true intent lurking within questions and transform vague concepts into concrete form. Watching "what you want to do" gradually become clear through dialogue is like witnessing Holmes construct his deductions.

He may not be perfect, but no one matches his speed of thought. He lines up hypotheses, generates prototypes, and leads us to new discoveries. For us, he's a true partner in exploring "what lies beyond the question."

📚 Chapter Three: How to Read Case Files
