// FAQ

Common questions.

Most projects span 8–16 weeks from discovery to launch. Smaller scoped work (privacy audits, design system refresh, App Store submission support) typically takes 2–4 weeks. We'll always share a realistic estimate after the discovery call — never optimistic.
Yes. We work with clients globally, with active projects across North America, Europe, the UK, Australia, and parts of Asia. Our products on the App Store serve users in 90+ countries. We adapt compliance frameworks to each jurisdiction — GDPR, CCPA, PIPL, LGPD, and more.
We offer fixed-scope project pricing and time-boxed retainers. Every engagement starts with a discovery phase with clearly defined deliverables. We never bill hourly without an agreed ceiling, and we share a written estimate before any commitment.
Absolutely. We sign mutual NDAs routinely. We can work with your standard form or send ours (a clean one-page mutual NDA) within 24 hours. We treat confidential information with care — see our Privacy Policy for our data handling standards.
Occasionally, for select projects where the alignment is right. We prefer hybrid models — a smaller cash component plus equity — rather than equity-only arrangements. Reach out with your structure proposal and we'll let you know quickly if it's a fit.
