From a conversation about technology to a new business.
I've worked on both the management and the engineering side, and I build with you from the first idea to the first working version.
Coji Mizoguchi, founderThe person you talk to is the person who builds it.
When you want to talk about technology in business terms.
You have an idea, but no sense of whether it's technically feasible
I listen and help you sort out what's possible, what's hard, and what to try first.
A development firm asked you for a specification first
You don't need a specification. I start by hearing what you plan to sell, and we decide together what to build.
There's no one in-house you can trust with technical decisions
I explain technical options in terms of cost, time, and business impact, so you can decide on them as business decisions.
What to build comes after we've talked and tested.
I don't start from a spec. I start by exploring what kind of business a technology could become.
Decide who it serves and what it offers
We work out together which customers a technology could help, what problem it would solve for them, and what value it would deliver.
Test it
I run small experiments to measure whether the technology really works, share the results as a report, and we pick the seeds that could become a product.
Build the first version
I turn the chosen seed into something that works and can be shown to customers. Watching how they respond, we decide together what to test next.

Can AI that reads support messages become a product for online stores?
Yes. Online stores share almost the same data shape, so this can be a product rather than a one-off fix. Next, check that the same hit rate holds on data from three stores.
I deliver validation results through Artifact Share, a product I built myself.

Work I don't take on
I don't take on development-only work against a fixed specification, or on-site and time-and-materials contracts, because this approach starts by deciding together what to build.
Coji Mizoguchi
CEO
More than once, I have seen something we worked hard to build go to waste because the business never took off. Building something good isn't enough. What we build only means something once it works as a business.
So now I talk with business owners before anything is built, work out together whether it can become a business, and then build it myself.
What I am working on now
- A search system for chemical substances
- Prototypes built with AI
- A data aggregation platform
- Building and running our own product, Artifact Share

Tell me about your business in your own words.
I'm happy to hear about new business ideas, whether technology can make them work, and how to get started, even before anything has taken shape.
I read every message myself and reply personally.
