About Sena

AI at full speed.Never AI slop.

We make website templates, design brands and websites, and build AI products, bringing in specialists as each project needs them. AI runs through every step; people make every decision.

Senior-led. Specialist-built.

Every project has one senior lead who designs, builds and stays with it to launch. Around them is a small circle of specialists we trust, and the work decides who joins. A bigger problem gets more hands, never more layers.

Our lead’s decade in product includes work for

  • Hoopit AI

  • Data engineeringPipelines, models, scaleNot needed
  • QATests, before every releaseJoins

A back-end specialist joins for accounts, payments and the API. Anyone else the work calls for joins the same way.

How we work.

Four rules. Every template we sell and every studio project is held to all of them.

  1. Human judgement, every time.AI drafts, builds and checks. People make and sign off every design decision.
  2. Written down.Rules, tokens and recipes ship with every template, so your AI tool keeps our decisions.
  3. Tested, and dated.We name a tool only after testing it by hand, and we show the date.
  4. The bar does not move.Every tool test is run again every ninety days, or its badge comes down.

One studio, three ways in.

Buy a template, have your brand, site or product made by our studio, or sell your own under the same standard. Every door leads to the same work: fast with AI, judged by people, ready for any AI tool.
