The team

Six humans plus one AI agent.

Engineering firm running on a small team that's been working together for years. Founders since 2023, designers and developers since longer. Plus our own production AI agent (open-sourced as SAE4U Agent) — runs inside our operations stack, supports client work, eats its own dogfood.

The crew

The people you'll work with.

When you engage Simple4u, you're not getting passed to a junior account manager. The same people who built our open source platform, who shipped our anchor case study, are the ones embedded in your operation.

Founder

Viacheslav Nesterets

Owner / CEO · Engineering Lead

Founder. The person you'll be on calls with. Three years embedded with WorldSpa across SEO, content, AI infra, video. Built the open source platform in this org.

AI · open source

SAE4U Agent

AI Team Member

Production AI agent we built and open-sourced. Runs inside our operations stack — handles knowledge ingestion, scheduled analysis, client-facing Q&A. The same agent we ship for client engagements. Eats its own dogfood.

How we work

Three principles that shape every engagement.

These aren't slogans. They're the operational defaults that come up in every project decision.

Honesty over comfort

If a project should pivot, we say it. If a deliverable isn't going to compound, we say it. Hard truths early prevent wasted quarters later.

Shipped over perfect

Marketing and engineering both reward velocity. We ship working things at quality, then iterate — instead of polishing in private until the moment to ship has passed.

Memory persists

The longer you work with us, the smarter we get. Our agents and our team keep institutional memory of your operation — open source memory architecture (sae4u-memory), open source agent platform, no lock-in.
