FAQs

Common questions

Can I interview the engineer before committing?

Yes — we welcome it. Your team gets a 30-60 minute technical interview before we confirm the engagement. If the fit isn't right, we find another.

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.

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.
