About 4dc · Estonia (EU)
Ten years in operations. Built for the agentic era.
Founded in 2016 in Tallinn, Estonia. We build pragmatic AI automations, internal operational tools, and modern web platforms. 100% owned by the client, running in private cloud or edge, with zero vendor lock-in.

Timeline
A decade of operational evolution.
We didn't start as an AI lab. We started inside revenue operations in 2016, solving business problems before writing agents.
Sales & Revenue Operations
Enterprise sales tooling, CRM implementations, and commercial pipeline architecture.
Process Architecture
Data analytics pipelines, executive BI dashboards, and custom operational software.
Machine Learning & Tooling
Automated document extraction, production ML pipelines, and internal back-office apps.
Agentic Systems & Edge
Deterministic multi-agent workflows, sovereign private-cloud execution, and modern edge platforms.
Engineering Philosophy
Why domain depth makes AI engineering actually work.
LLMs can generate code at unprecedented speeds, but they have zero intuition for operational reality. We combine deep business context with deterministic engineering rigor.
Code is cheap. Domain context is rare.
Generative AI has commoditized boilerplate code. The bottleneck in software engineering is no longer typing syntax—it is understanding precisely how invoices flow, how sales pipelines qualify leads, and where operational edge cases live. A decade inside business operations provides that context before writing a single line.
Deterministic boundaries over black-box chaos.
We reject unconstrained chat widgets and brittle autonomous loops. We engineer cyclic state machines (LangGraph), strict schemas (Pydantic/Zod), regression test harnesses (Promptfoo), and mandatory human-in-the-loop validation for all critical paths.
100% Client ownership & sovereign execution.
We never lock you into proprietary platforms or recurring SaaS fees to us. Everything we build is deployed directly into your own AWS, GCP, Azure, or Cloudflare infrastructure, with complete source code transferred to your GitHub organization on day one.
Zero maintenance by architecture.
Fragile dynamic servers and vulnerable CMS plugins are operational liabilities. We favor static edge compilation (Astro), serverless Workers, event-driven queues, and hardened API microservices that run unattended for years with near-zero hosting costs.
How We Operate
Senior engineers. Direct access.
We operate as an agile, high-density engineering squad. No account managers, no junior handoffs, no bureaucratic telephone games.
Direct Access to Senior Builders
You interface directly with the senior engineers designing, testing, and shipping your code. Context never degrades across managerial layers.
Private Cloud & Edge Deployment
Every workflow, database, and model runtime executes within your security perimeter and data sovereignty boundaries (EU GDPR compliant).
Fixed Scopes & Tangible Deliverables
Every sprint delivers working code, automated test suites, and documentation that you own outright—whether you continue to the next phase or not.
