Engineering firm · NYC · since 2023

An engineering firm.
Not an agency, not a startup.

We embed into your business as your full-stack technical team — software development, AI infrastructure, creative production, SEO, ongoing operations. R&D and production under one roof.

We don't sell projects. We don't sell subscriptions. We run a piece of your operation.

Five service lines. One team. One roof.

Engagements typically include 2–4 of these running in parallel for one client. Each service stands on its own; together they cover the full surface a digital-native business needs an embedded technical partner for.

Founder · Engineering Lead

An engineering firm built around one rule: we run a piece of your operation. Not a project. Not a subscription. We embed, we ship, we stay.

After three years embedded with our anchor client across SEO, content, AI infrastructure, video production, and ongoing engineering — I built Simple4u to do this for a small number of digital-native businesses at the same depth. Open source platform, transparent retainer, real engineering.

The team

Six humans plus one AI agent. Building together since 2023.

The same people who built our open source platform are the ones embedded in your operation. No hand-off to junior account managers.

Anchor case study

Three years embedded with WorldSpa — premium spa group

SEO + content + AI video production + custom Stripe / dynamic pricing integration + ongoing engineering. The full Simple4u model in production at one client. Read what we built, what we shipped, and what the partnership looks like in practice.

Read case study

Built for businesses too small for an in-house team but too dependent on tech for project-only work.

Most digital-native SMBs and agencies sit in an awkward middle: too small to hire 4–5 specialists full-time, too tech-dependent for a project-only agency to keep pace. The embedded engineering firm model fills that gap.

Traditional agency / project shop

  • Sells discrete projects. When the project ships, the relationship resets.
  • Different team for software vs. SEO vs. video vs. AI — fragmented.
  • Bills hourly or per-deliverable — interests misalign with longevity.
  • You explain your business again with every new vendor.

Engineering firm (Simple4u)

  • Embeds long-term. We learn your operation, defend it as it scales.
  • One team across software, AI, creative, SEO, ops — coordinated.
  • Monthly retainer at $10–15K. Predictable. We stay aligned by default.
  • Memory persists. The longer you work with us, the smarter we get.
