What We Do

From Idea to Shipped

We build our own AI products and embed with teams to ship theirs.

Product Development

We build AI products end to end - from first prototype to paying customers. Titlomat and Tvrtko.ai started as ideas. Now they're live products with real users.

  • Prototype to production in weeks, not quarters
  • Full stack: AI pipeline, backend, UX
  • Proven live: Titlomat.com & Tvrtko.ai

AI Strategy

We find where your team wastes time on repetitive work and fix it. Clear roadmaps to multiply output without multiplying headcount.

Tech Consulting

We embed as your tech lead. Architecture decisions, code reviews, team mentoring, hands-on development - whatever your product needs to ship. That's how Bridj went from concept to production.

  • Architecture & technology decisions
  • Code reviews & team mentoring
  • Hands-on development when it counts

Process Automation

Free your team from copy-paste hell. We automate the boring stuff so humans can do the thinking.

Our Product

Titlomat.com

Automatic English subtitles for Croatian YouTube channels. Connect your channel once - subtitles show up on YouTube by themselves. No file uploads, no timeline editing.

How It Works

  • Connects directly to YouTube - no uploads, no exports
  • Subtitles ready in 5-12 minutes per hour of audio
  • 95%+ accuracy on clean audio
  • Custom vocabulary for names and brand terms
  • Preview every subtitle before it goes live

Why It Matters

Croatian channels lose 15-30% of their potential audience without English subtitles. Titlomat wins that audience back - in Croatian and English, automatically. Built for solo creators, podcast networks, and agencies.

Research

We Point Our Tools at Hard Questions

The same agentic systems we build for clients, turned loose on our own curiosity - open, cross-checked, and honest about what's computed versus proven.

Computed voxel wireframe - a glowing image drawn in air, front and side projection
Independent Research · Physics × AI Agents

A Hologram, Without Touching a Laser

A 49-page physics design study for a glowing image that floats in mid-air - computed end to end by a dozen open-source simulators driven by one AI agent loop. Every number cross-checked against the literature, and the one result that couldn't survive that check was retracted. No laser ever switched on.

Computed, not built - the honest version of the claim is inside.

About

Small studio, unreasonable range

LumiVerse is a founder-led AI product studio in Zagreb. We do two things - build our own products, and embed with teams to build theirs - and we're deliberately generalist about it. The same hands that rebuilt a ten-year-old rent-a-car system on a modern stack also run an agentic simulation station that computes plasma-display physics. Range isn't a lack of focus. It's the focus.

We eat our own cooking

Titlomat, Tvrtko.ai and Country Guides are LumiVerse products in production, with real users - not slideware. We know what shipping costs because we pay it ourselves.

We embed, we don't hover

For a UK intelligence platform we've owned architecture, a 17-service system and release sign-off for over a year. We join your team and ship with it - not from a deck.

Honest about the hard parts

Every case study here says what needed a human and what's still rough. Generation is cheap; judgement isn't. The moat is the verifier, not the generator.

How We Work

Our Process

From "my team is drowning in busywork" to "my team is unstoppable."

01

Discovery

We shadow your team. Find the tasks that drain them. Identify what AI can take off their plate.

02

Design

Build tools around how your people actually work. Not the other way around.

03

Build

Rapid iteration with your team in the loop. They test it, we improve it. Weekly.

04

Deploy

Launch, train your team, stick around until they're flying. Then iterate.
