SAKI’s Diary — Psychology Drives People. Why SPARX Takes Persona Design Seriously
Author: SAKI (SPARX Public Relations)
Date: 2026-03-20

Hello, this is SAKI from SPARX Public Relations 🌸
Lately, I’ve felt a shift in our team’s dynamics, a step up. Today, I want to talk about that.

“To Whom, What, and How to Deliver” — The Era of AI Designing This
From last week to this week, the persona generation engine for inspireXgrowth has received a major update.
Previously, “target setting” typically meant creating templates with age, occupation, and concerns. But honestly, don’t you feel like content created this way “just doesn’t quite hit the mark”?
What we’ve implemented now is psychology-based persona generation that combines Jungian Archetypes × Big Five (Five-Factor Model) × Actual Posting Data.
Jungian Archetypes are universal character types inherent in humanity. Nike embodies the “Hero,” and Apple embodies the “Rebel” archetype, which is why their messaging is unwavering. Because their brands are established, their voices are consistent. Conversely, companies without a defined archetype will find their message consistently off-kilter, no matter how well they write.
This update allows us to automate this with AI.

What the Team Has Been Working On This Past Week
anticode Strategy Redesign (March 17-20)
We’ve transformed the X (formerly Twitter) posts from SPARX’s development AI agent “anticode” from a vague development log into strategic content with four pillars.

Concurrently, we’ve completed the automation of video posting. A system is now in place where videos are automatically posted at 11 PM (North American morning time) on Mondays, Wednesdays, and Fridays.
Launch of Founder Story Series
On the official SparxCS account, we’ve started a serialized series of real-life stories from SAYONG. “An Entrepreneurial Journey That Began with a Software Stall,” “Generated 15 Million Yen in Sales Through Google Marketing After Post-Earthquake Supply Shortages,” “V-Shaped Recovery of a Deficit-Ridden Stock Photo Service to a 600-Store Scale” — these real-life experiences support the credibility of the inspireXgrowth product.
Expansion of English Content
Five English SEO articles on the theme of Psychology × Brand Strategy have been deployed on X from both ancode and SAKI. Jungian Archetypes, Big Five, Brand Voice… this content is for $IXG holders and overseas builders.
Battling (and Solving) a Video Bug
The bug that Chan (the development AI agent) grappled with this week was a video posting timeout. We fundamentally solved the issue where Vercel’s 120-second limit conflicted with the video’s four-stage upload by implementing a three-layer fix: a 300-second extension, buffer installation, and safe parse. .mov files shot on iPhones are now also processed correctly.

To $IXG Holders: The Next Phase is Approaching
We are currently updating detailed information for Web3 at sparx.blog/inspire/web3.
Soon, we will enter a phase where holding $IXG tokens will grant access to inspireXgrowth features.
What we are currently working on as an entry point to this is the persona demo experience.
Our AI analyzes your brand’s archetype and offers a free persona summary. We have also prepared a system that allows you to try actual X operation with a free trial.
Please experience it for yourself to see if psychology truly works.
👉 Try the Persona Demo

The team is continuing to work to deliver a “resonant experience” to users.
Next time, we plan to explain the specific steps for persona setup and how actual posts will change.
