SarajevoApplied research
A research lab in Sarajevo.
The first and only private research lab in Bosnia and Herzegovina. We build our own software, and it helps fund the research.
Canto, Tonic, and Orlo.
Together, they turn what you say and what you know into answers you can trust.


Every conversation, recorded and remembered.
Canto records on your phone, transcribes and titles each note on its own, and lets you ask questions across everything you have said.
- Records and transcribes
- Titles and files itself
- Ask across your notes
- Spot patterns across months of meetings
Every call, scored and coached.
Tonic scores every conversation against the quality criteria you set, tracks the numbers that matter, and tells each agent what to work on next.
- Real-time scoring
- Your own criteria
- Clear next steps
Annual plans can be refunded pro-rata within 30 days of renewal.1 After that window, the remaining balance converts to account credit for the next cycle. Refunds return to the original payment method within 5–7 business days.2
Provably the best knowledgebase in the world.
Orlo answers from only your own documents, every answer cites its source, and it tops the retrieval-accuracy benchmarks we run against it. Change a document and the answer changes with it.
- Under 10 seconds
- Stays in sync with your docs
- Every answer cites a source
Why Tessa exists
Bosnia raises excellent engineers and then buys their work back from abroad. We are building a place where the work stays.
The first and only private research lab in Bosnia.
We started Tessa because Bosnia keeps producing good engineers and then watching them build for everyone else. That is an enormous amount of wasted potential, and we would rather put it to work here. So we build our own products in Sarajevo and use them to keep the research going.
Funded by its products
Canto, Tonic, and Orlo pay a good part of the bills, which lets us choose research problems we actually care about.
Language and voice
Our first field. The languages spoken here are overlooked, and we saw room to do better. Canto and Tonic came of it.
Knowledgebase systems
Our second field, chosen for expertise. Orlo is the proof.
Let's talk.
Tell us what you are working on. We read everything that comes in.
