00 — Approach
We don't build prototypes for the drawer. We build software that passes audits, runs across managed fleets and can be maintained for years without fear of every change.
Native where it matters.AI where it adds value.No hype.
Experience
Nearly13years of practice
Nearly 13 years of practice. Ten of them without AI.
We built the foundation long before AI started writing code — from a first project in Objective‑C to an SDK for hundreds of millions of users. Honest work, on real projects. AI came on top of that foundation, which is why we know where it genuinely helps and where it would only hide a lack of understanding.

04 — Proof
From a document to structured data. In production.
Doklady.ai is the first product built on DS‑Intelligence. It reads invoices, checks accounting logic and exports to ISDOC — running in EU production.
- 01 Intake
PDF, email, scan
The document enters a controlled environment — no loss of control over the data.
- 02 Extraction
Fields, line items, VAT
The model understands the document structure and the supplier context.
- 03 Validation
Accounting rules
VAT, control statement and the document's internal logic are checked.
- 04 Export
ISDOC, accounting system
Structured output ready for the next system or person.
05 — Ecosystem
One company. Two pillars.
Engineering is the foundation, DS‑Intelligence the direction. The products around them prove both work in real operation.
