Our engagement models flex to your stage: fixed-scope, staff augmentation, or monthly retainers.

FAQs

Common questions

What happens if the engineer underperforms?

We guarantee a replacement within 7 business days at no cost if the engineer doesn't meet the agreed-upon quality bar during the first 30 days.

How are your Rag Engineers vetted?

Every engineer goes through a 90-minute technical + systems-design interview with a senior from our team, plus reference checks. We record interviews so you can audit the process.

Who owns the IP?

You do. All code, documentation, model weights, and deliverables are assigned to you on payment. Our master service agreement spells this out explicitly.

Do you sign NDAs before a scoping call?

Yes — standard practice. We circulate a mutual NDA before any detailed conversation about your product, data, or roadmap.
