A retainer engineer stays with your codebase, learns the business and takes ownership of what they ship, so the product keeps moving even when you can't be there to direct it. And when you need a security review or a designer, the rest of the team is there. How quickly can someone start? Usually within a week of agreeing the tier - no hiring cycle, no months-long ramp. Can we change the tier or stop? Yes. Retainers are month to month with no lock-in. Scale up or down, or stop, as your roadmap changes. Do we own everything you build? Yes, 100%. Code, infrastructure, docs and credentials stay yours. How much does a retainer cost? Retainers start at $4,000 a month for the part-time tier. Dedicated and embedded tiers add more hours and faster response. Month to month, no lock-in. ## Hear from us within 24 hours. **Prashant and Khushi** Partners @ Zeroic Need senior capacity without hiring? Tell us what's on the roadmap.
