We are optimists.
Who believe in our ability to improve our lives.
Do something that matters to us.
Optimium (= Optimistic + sum) is built on the idea that optimism — paired with a sustainable view of the world — can become the smallest unit (sum) of society and drive people's lives in a positive direction.
Our wish is to live in the space between heart and heart, to draw out individual curiosity and passion, and to write new scenarios from there. As we keep thinking about society and civilization, each person and each life faces new challenges — and from those challenges, new scenarios emerge.
That is what we ourselves take on with everything we have.
Case Studies
We specialize in generative-AI agents built to run deep inside real business operations.
Truck Inventory Search Agent
Find the right truck across hundreds — or thousands — of units, in plain language
Built an agent that turns vague salesperson queries like "4-ton flatbed, under 200k km, ready to deliver" into concrete vehicle suggestions from live stock.
Used Truck Pricing Agent
An AI agent that proposes fair acquisition and resale prices for used trucks
Built a pricing agent that weighs year, mileage, body configuration, condition, and market trends — supporting acquisition, resale, and price revisions on slow-moving inventory.
Truck Condition Inspection Agent
A digital intake inspection agent that replaces tacit visual judgment with image AI
Built an inspection agent that reproduces veteran appraisers' visual judgment of incoming trucks — scratches, corrosion, body damage, paint — using image AI and rule-based logic.
