Delivery
How the engagement runs
- Phase 1
Scope your hours band
We agree on a Light, Standard, or Heavy hours band on a call. You get a fixed monthly price before anything starts.
- Phase 2
Weekly check-in + Slack
A brief weekly sync keeps you in the loop. A dedicated Slack channel means asynchronous communication flows without friction.
- Phase 3
Hours roll over quarterly
Unused hours roll over within a calendar quarter. They never expire mid-quarter; you get what you paid for.
Flexible capacity
Hours bands
Light
20 hours / month
Routine patches, dependency updates, and occasional small additions. Best for stable products in maintenance mode.
Standard
40 hours / month
Ongoing maintenance plus a steady stream of small feature work each month. Our most common retainer band.
Heavy
80 hours / month
High-velocity maintenance with significant capacity for product additions. For products that need continuous engineering attention.
Pricing scoped on a call. Every band includes weekly check-ins and a dedicated Slack channel.
Is a Retainer right for you?
Best for
- Existing clients, post-launch: the team that built it maintains it
- Products that need guaranteed engineering availability without a full squad
- Teams who want predictable monthly cost and defined response SLAs
- Products in steady state with occasional small feature needs
Not for
- New clients: start with a Tech Audit or Discovery Sprint first
- Active new-feature development: see Project Build or Embedded Squad
- One-off bugs on a product we did not build: an ad-hoc engagement fits better
- Teams who need full-time dedicated capacity: see Staff Augmentation
