AXSYS

Built. Shipped. Operated.

Where real-world demand becomes software products.

Based in New York, we build and operate online products of our own and provide commissioned software engineering for select clients.
Running our own products gives us an owner’s perspective on every product we touch.

Built from demand, not guesswork.

A few examples of what that looks like in production. Zyrable and Resellify are software products operated by AXSYS LLC.

B2BSaaS

Real-time social monitoring and alerting.

Zyrable monitors profiles and search queries across supported social platforms and news sources, then delivers source-linked alerts to Discord. Its developer API exposes the same monitored event stream for internal tools, automations, and custom integrations.

  • Posts, replies, quotes & profile changes
  • Per-channel Discord routing
  • WebSocket & REST developer APIs

Systems we know

From product surface to systems core.

Architecture gets interesting when real users, real traffic, and real-world failures enter the picture. That is when a system’s true constraints and tradeoffs come into focus, and where we do our best work, engineering for reliability, performance, and long-term operation.

Work with us

Serious engineering for serious products.

We work with a focused group of companies on consulting and commissioned builds, keeping the work close to the product, the code, and the systems underneath.

01What projects are a strong fit?

Engagements span marketing websites, operational dashboards, cross-platform applications, real-time systems, integrations, and internal tools. We are most useful when product and engineering decisions need to move together.

02Can you lead from idea through launch?

Yes. Work can begin with offer definition and prototyping, then continue through production engineering and launch. The target is the smallest complete release that validates demand without creating a disposable foundation.

03Can you improve an existing product?

Yes. We can enter an existing codebase and improve it without losing what users already value. An audit, stabilization pass, redesign, or focused performance engagement can all be sensible starting points.

04How do commissioned engagements work?

Engagements begin by aligning on the audience, opportunity, and success criteria, then move through focused design and development loops with working software, visible decisions, and a practical ownership plan.

What we believe

The strongest products begin with a problem people already care about.

That lesson came from building alongside clients. It now guides what we create, acquire, and improve.

Built with intention.
