We advise. We build. We invest.

In the companies founders carry quietly for years — and in the work it takes to finish them properly.

What we do
  • Strategy, positioning, pricing, hiring, go-to-market. We sit beside founders during the decisions that compound — the choices that look small in the moment and define the company three years later.

    Hands in the actual work, not slideware delivered from a distance. Brought in early — before the wrong cofounder, the wrong investor, the wrong feature roadmap. Sometimes for a single conversation, sometimes for the duration.

  • Internal automations, customer-facing AI products, the unglamorous infrastructure that quietly compounds. We write the prompts, train the models, wire up the integrations, and put the thing in production.

    Shipped to real users, not demoed in a meeting. The kind of system that still works on a Sunday morning when its owner is on holiday.

  • Early stage, conviction-led, written checks only. We back the small number of companies we'd want to work at ourselves — and stay close enough to help when it matters.

    Capital, network, and our own hands when the company needs them. No spray-and-pray, no board theatre, no investor letters written by AI.

Ονείρο
ó-nee-ro · dream

Oneiro is Greek for dream the kind a founder carries quietly for years before anyone else sees it.

We chose the name because that's where our work begins: with someone who already knows what they're building, and needs partners serious enough to help them finish properly.

We advise, we build, we invest. For the same kind of person, in the same kind of way directly, with our hands in the work, without process for its own sake.

— What happens after the dream.

All men dream — but the dreamers of the day are dangerous, for they may act their dreams with open eyes, to make it possible.
