Build the right system.

Then get out of its way.

3rd Interval is a boutique technical consultancy helping growing teams replace fragile tools with clean, scalable software.

We work fast. We work carefully. We don’t need perfect specs.


Most teams don’t need more software.
They need fewer breakpoints.

We step in when systems are duct-taped, automation is overdue, or AI feels important but abstract. We make sense of the mess, design the right shape, and build something that lasts.

Not an agency.
Not a dev shop.
A senior technical partner.


What we’re usually brought in for

  • Rapid prototypes that need to become real
  • MVP rebuilds cracking under growth
  • Internal automation and applied AI
  • Workflow and data systems that fit how teams actually work
  • Accessibility and compliance fixes done properly

If the requirements are unclear, the stack is mixed, or the timeline is tight, that’s normal for us.


How we work

  • Small, senior team
  • Direct communication
  • Plain language, no theater
  • Speed without shortcuts

We design systems that can be handed off, extended, or maintained without us. That’s intentional.


We’ve built and rebuilt systems for startups, local businesses, and mission-driven organizations who needed reliability more than hype.

Long-term clients tend to stay because things stop breaking.
