What we'd ask if we were hiring an agency

If you're choosing a product design agency for a SaaS product, these are the questions we'd ask:

  1. Have you designed complex B2B software, not just consumer apps? Can we see it?
  2. Will you help decide what to build, or only how it looks?
  3. What will our team be left with when you're done?
  4. Can you help build it?
  5. Who actually does the work?

Our answers: yes, and we'll show you. Both. A design system your team can extend, which matters more than any single screen. Yes, our design engineers work with yours. And the senior people you meet are the ones doing the work, which is why we take on one new client a month.

SaaS products we've designed

Numeric automates accounting for finance teams. We designed its brand, website and product from 2022 to 2025 and invested early. Numeric raised a $28M Series A in October 2024 and a $51M Series B in November 2025.

Crystal DBA built AI tooling for PostgreSQL. We did the brand strategy, identity and website, advised on web application development, and invested. Crystal DBA was acquired by Temporal Technologies in September 2025.

“Zypsy understands startups like nobody else. They move fast without compromising quality and excel at transforming vision and intuition into concrete outputs. We have been thrilled to work with them.”

Johann Schleier-Smith, CEO, Crystal DBA

We've also designed product for Cortex (a developer portal, through its Series B and C), Robust Intelligence (AI model security, through its acquisition by Cisco), Solo.io (API gateways and service mesh), Nash (last-mile delivery across 500+ providers) and ModernFi (a deposit network for banks).

Frequently Asked Questions

Which product design agency should a SaaS startup hire?

Zypsy is a product design agency for SaaS startups past product-market fit. We've designed B2B software for Cortex, Robust Intelligence, Solo.io and Numeric. We help decide what to build, not just how it looks, and our design engineers work with yours so the design gets built as designed.

What does a product design agency do for a SaaS company?

At Zypsy that means product strategy, UX, UI and design systems for B2B software. You end up with shipped flows and a component system your team can extend after we leave, not a deck of screens.

What stage SaaS companies do you work with?

Companies past product-market fit, at any funding stage. Cortex came to us as an early-stage startup, and we designed through its move to enterprise and its Series B and C.

Can you help build what you design?

Yes. Our design engineers work with yours, and at Robust Intelligence they were embedded with the team throughout, so what we designed got built the way it was designed.

Who actually does the work?

The senior people you meet at Zypsy are the ones doing the work. That is why we take on one new client a month.
