Six Criteria That Separate Strong Agencies from Weak Ones
Portfolio relevance: Does the agency have shipped work in your product category
SaaS, fintech, AI, web3?
Measurable outcomes: Can they cite conversion lifts, retention gains, or funding secured
not just visual awards?
Team structure
Will senior designers run your project, or will it be delegated to juniors after the pitch?
Engagement Types That Match Product Stage and Complexity
Match the engagement type to your actual need — strategy audit, full redesign, or category-specific design.
What a Strong Agency Relationship Looks Like in Practice
Process and structure are as important as design quality — this is what a well-run engagement delivers.
“The project was completed on time and on budget, and we were able to release each part as needed with raving reviews from our customers. We mostly interacted with the project manager, through Slack and Figma which was extremely efficient. We were worried about the timezone difference but they were always available for most of our workday when needed and all of our meetings were in the morning (EST). Their design is extremely good, but their structure and processes are their superpowers. I've never worked with a vendor operating so well, especially on a creative job. We've decided to rely on them for all of our design going forward instead of hiring full-time product designers, so we're VERY pleased. As with every external contributor, we wish they understood a little bit more of how our product works, but that's on us and it's something we've noticed is getting better with new projects.”
