Brno, Czechia

I build compliance infrastructure and the products around it, for teams that can’t afford to be wrong about who they’re doing business with.

About Sadat Nazarli

Every payment, every onboarding, every new partner starts with one question: can we trust them? I build the systems that answer it. Verifex screens people and companies against sanctions and PEP sources, across alphabets, and returns a decision you can defend: what was checked, what wasn’t, and why. Summativ brings that same rigour to how schools in Azerbaijan assess their students.

Verifex

A sanctions & PEP screening API that gives compliance teams answers they can defend.

  • 47 sources catalogued, from OFAC, UN, EU and UK lists to GLEIF and UK Companies House
  • Fuzzy, phonetic & transliteration matching across alphabets
  • Ownership chains screened, with OFAC 50% Rule calculations as analytical support
  • An evidence record for every decision: which sources were checked, and which weren’t
  • A missing source withholds clearance, so incomplete work never reads as clear

Summativ

Assessment infrastructure for Azerbaijani educators.

Small and large summative exams (KSQ / BSQ), exam access, student data, grading and result analytics in one system, so a school’s assessment stops living in scattered spreadsheets and group chats.

Try the engine

Same person.
Different alphabets.

The hard part of screening isn’t exact matches. It’s knowing that Садат Назарли, Sədat Nəzərli and Sedat Nazarlı are one person, and that Sadat Nazarov probably isn’t. This is a pocket-sized version of that logic. Type any spelling.

A toy version of the matching problem Verifex solves in production: one person, many alphabets, and every decision explained.

How I build

Principles

  1. 01

    Recall comes first.

    In sanctions screening a missed match is a regulatory breach, not a bug. Verifex tunes for recall first and publishes its benchmark with the limits attached: what was measured, on what, and what it doesn’t prove.

  2. 02

    Every decision leaves evidence.

    Each check records which sources it ran against, which list versions, and which sources it couldn’t reach, so any answer can be reproduced in front of an auditor.

  3. 03

    Trust shouldn’t need an enterprise contract.

    Self-serve from $49 a month, with free screens to start. A two-person fintech deserves the same protection as a bank.
