Automation
What we do
Engineering that bends to your idea.
We take on the technical work other teams hand off — custom builds, tricky integrations, and the glue that makes platforms talk to each other. No templates, no hand-offs to junior teams.
Platform Integrations
APIs, CRMs, payment rails, and data pipelines wired together cleanly — so your stack runs as one connected system, not silos.
Automation & Workflows
We automate the repetitive — publishing, reporting, sync jobs, and the handoffs between tools — to give teams their time back.
Front-End & Experiences
Interactive sites, microsites, and brand experiences with motion and polish — built to feel as considered as the work they showcase.
Social Media Tooling
Scheduling, analytics, and content pipelines connected to the platforms your audience lives on — posts and reporting in one place.
Technical Consulting
Architecture reviews, build planning, and pragmatic advice when you need a senior engineer in the room before committing.
Capabilities
One studio, across every surface.
We work fluently across three worlds — and the integrations that connect them. Here's where we plug in.

Integrations
We connect to the tools you already use.
From off-the-shelf platforms to AI agents to bespoke endpoints, we wire your stack together so data flows where it should — no copy-paste, no silos.

Our approach
A straight line from idea to launch.
The name is the philosophy. Linear — a clear, direct path with no wasted motion. Arc — the full journey we carry a project across, from first sketch to shipped product.
We're a senior team that takes ownership of the technical hard parts. No layers of account managers, no template factories — just engineers who care about clean code, reliable integrations, and work that holds up under real use.
1
Discover
We dig into the problem, the platforms, and the constraints before writing a line of code.
2
Architect
A clear build plan and integration map, so you know exactly what's being built and why.
3
Build
Tight iteration, visible progress, and code written to last beyond the launch.
4
Launch & support
We ship it, connect it, and stay close while it settles into real-world use.
Engagements
Every project is scoped to fit.
We don't do off-the-shelf packages. Tell us what you're building and we'll come back with a clear plan and a quote — or just connect with our team to talk it through.
