Quick selection tips (how to choose the right partner)

• Match scope: pick a UX-led studio for discovery, research and product design; pick a full-stack product studio or consultancy if you also need backend/scale engineering.
• Check portfolio & outcomes: look for case studies similar to your industry or product type (SaaS, e‑commerce, enterprise, public sector).
• Team size & tempo: smaller studios give hands-on senior designers; larger consultancies scale faster for enterprise programs.
• Process evidence: prefer teams that publish their UX process (research, prototyping, testing) and design-system work.
• Contracts & IP: confirm ownership of design/assets, support/maintenance and handover arrangements.

If you’d like, I can:

• Narrow this list by city (Sydney, Melbourne, Perth, Brisbane, Adelaide) or budget range, or
• Produce a 1–page comparison matrix (capabilities, typical project size, estimated budget bands, sample clients) for your top 4 picks, or
• Draft an RFP/email template you can send to shortlisted firms.

Which of those would be most helpful? (If you prefer, tell me city, project type and budget and I’ll shortlist best matches.)
