"We engaged Guidea for dozens of design innovation and execution projects at PayPal over a ten year time period. Their deep expertise in FinTech as well as mobile design strategy allowed us to quickly launch innovative experiences across the globe. For customers, merchants and PayPal partners including Discover, Home Depot. Starbucks and others. Their longest running success was Mobile Express Checkout, which helped provide a 33.7% spike in conversion rates for merchants and scaled to process billions in mobile payments annually by 2015. I wouldn't hesitate to hire them again."

"Guidea has created hundreds of designs for my development team to reference. Their work is super professional. The designs are well thought out, user friendly, visually appealing, and most importantly, clearly documented for developers."

"The project went very smoothly."

"They’ve always gone above and beyond. We work closely with them, and we’re really happy. My team basically considers Guidea as our team. They’re very knowledgeable in their field and are experts in usability and UX areas, information architecture, research, and wireframing. They’re top-notch."

"Guidea’s biggest asset is their research-driven design. Other companies might make research part of what they do, but research is the center of what Guidea does. Something that really stood out about working with Guidea was that we got their top talents working on our project, which made a huge difference."

"The UI designs Guidea delivered were leaps and bounds better than what we started with: grounded in user research, systematized, and beautiful. Our users loved the updates to our web app and the internal team was really excited by the momentum that work delivered." 

"I really enjoyed that they’re a boutique design firm; they provided a personal touch and personal attention. We worked with really talented and dedicated people who listened to our needs and expectations, acting as active partners during those discussions, and creating a very collaborative environment."

"Working with Guidea was one of the best decisions we’ve made, because of the breadth of experience that they have working in different industries. They brought all of that knowledge and insight to bear and really delivered some powerful insights on specific questions that helped guide the product strategy."

The team is flexible and adapts its approach to suit the individuality of the challenge. Guidea (A Theresa Neil Design Company) does not rely on scripted approaches and instead addresses each project on a case by case basis. It always felt as if they were highly engaged and thinking about the problem as thoughtfully as we were. They are one of the most creative vendors I’ve had the opportunity to work with."

"With Guidea, we were very clear and confident on what direction we needed to take after the project was completed."

"Theresa Neil's strategic approach and her UX/UI team were able to understand the mobile app approach quickly, audience needs, and current situation to make immediate, impactful recommendations utilizing a heuristic review approach and industry expertise to help ensure a world-class UX/UI."

"Theresa and her team were a great partner when we redesigned a whole analytical financial platform and set the path for good usability for years to follow. We did thorough market research and planning to get us a great new experience. Executives, internal staff, the sales teams and clients loved the new designs. It would be great to work with Theresa and her team again."
