With technology,we make it work

So much work is still written off as "nothing we can do."
We combine AI, software, and workflow design to build systems that actually move work forward.

Products

We don't just support businesses.
We build our own.

We build and run these products ourselves, improving them every day.

showhours editing screen: a one-week timeline showing open slots as candidates, with blocked and published hours color-coded

showhours

Pick the hours to block, not the slots to offer.

No need to add candidate slots one by one. Every opening in your Google Calendar lines up as a candidate — block the hours you don't want booked, and publish the rest. Guests book without an account. Currently in beta.

Dazbench dashboard: today's task list with an in-progress task the AI is working on

Dazbench

Tasks your AI can actually run.

A task board you manage together with AI. Write a one-line note and AI fills in the purpose, background, and acceptance criteria — readable and writable directly from Claude or ChatGPT. You decide when it's done. Currently in beta.

Company

From ads to the web, and on to AI.

The tools change; what we do doesn't. For 19 years, CreateSea has been getting stubborn problems unstuck with technology — for more than 1,500 client companies. Today we also build our own products.
