OPPORTUNITY / CHALLENGE
What specific goals or objectives did you hire Jett to accomplish?
We brought Jett on board to design our very first corporate website. They didn’t just deliver a website — they gave us a digital presence that truly represents who we are. The result was so strong that we quickly expanded the partnership, trusting them with the online platforms of our partners as well.

RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The launch of our first corporate website completely shifted how we’re perceived online. Within the first three months, we saw a 40% increase in inbound partner inquiries, our average time-on-site tripled, and our brand started showing up in conversations where we were previously invisible. The site didn’t just give us credibility — it opened doors. That traction is exactly why we brought Jett back to work on websites and digital products for our partners as well.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
From a project management perspective, the collaboration was seamless. Jett kept everything on track with clear timelines, proactive updates, and zero surprises. What stood out most was their ability to adapt — when priorities shifted, they adjusted without losing momentum. The project launched ahead of schedule and under the expected budget, which gave us the confidence to scale the partnership and trust them with more complex initiatives.

What did you find most impressive or unique about this company?
What impresses us most about Jett is their mix of creative precision and business sense. They didn’t just design a website; they asked the right questions to understand our goals, our audience, and the bigger picture. That balance — delivering clean, striking design while making sure it drives real business outcomes — is what sets them apart.
Are there any areas for improvement or something Jett could have done differently?
If anything, the only challenge was that Jett moves fast — sometimes faster than we were ready for on our side. A bit more time built in for internal reviews would have helped us keep pace. That said, their speed and efficiency are also what made the project launch ahead of schedule, so it’s a strength as much as an area for fine-tuning.

Describe the scope of work in detail. Please include a summary of key deliverables.
We initially engaged Jett to create the branding and UI/UX design for our first DeFi dashboard, and the results exceeded our expectations. Later, when I launched a new business, Jett supported us from the ground up - handling everything from brand and market research to the design and development of AlphBanx, a leading DeFi platform. Once again, the outcome went above and beyond what we had anticipated. Market research; - Brand development (identity, logo, graphic design); UI/UX design; No Code Development (Framer, website); Web Development (React.js / Node.js, Typescript).
RESULTS & FEEDBACK

They delivered a world-class brand — both visually, through exceptional branding and design, and technologically, through high-quality development. This strong foundation played a key role in securing funding to support our future growth.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
The project management was outstanding. They anticipated our needs and adapted their approach as the project progressed. Communication was always professional and fast, and they kept me informed at every stage — often providing clarity on the next steps before I even had to ask. This proactive approach made the entire process smooth and stress-free.

The client submitted this review online.
BACKGROUND
Please describe your company and your position there.
I am the Founder of Ronin Ventures - a blockchain software and infrastructure company.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Jett?
Lack of user experience design in goods is one of the challenges of working in the blockchain industry. We recognized an opportunity to create solutions that would provide users with a cutting-edge UI and UX similar to those of already-available solutions in other industries.
As a result, we employed Jett to help us with the UI/UX design of a number of products, such as an NFT Marketplace, Web3 Wallet, and a few others.
SOLUTION
How did you select this vendor and what were the deciding factors?
An important consideration while hiring is, overall enthusiasm for the projects. We were seeking for a team that had a strong desire to satisfy and was "hungry" for work. Additionally, we were searching for a group that could adapt to the demands of a sector like blockchain which is changing quickly.
When we chatted with Jett, we discovered all of these qualities in addition to the capacity to build lasting relationships. They presented the brief with high professionalism and demonstrated a readiness to adapt to modifications. It was clear that we could collaborate with them on a variety of projects.
Describe the project in detail and walk through the stages of the project.
The first task for Jett Develops was creating UI/UX design for NFT Marketplace. The deliverables were: competitors’ research, user flow creation, wireframing, and prototyping.
After the first phase, I decided to assign one more project - Web3 Wallet design - since I liked the way guys managed to complete the research. As of July 2022, Jett Develops delivered for our company the following products:
UI/UX design for NFT Marketplace
UI/UX design for Web3 Wallet
UI/UX design for Blockchain Explorer
UI/UX design and development for NFT Collection Website (under development)
UI/UX design and development for Web3 Wallet Landing page (live now)
2D and 3D models for the collection
Multiple small UI engagements.
As for the tech stack, we utilize Jett Develops mostly for the frontend (React) based tasks, Unity tasks, and Smart Contract Development (Rust).
How many resources from the vendor's team worked with you, and what were their positions?
4 UI/UX designers, 2 Front-end developers, 1 Blockchain developer, 1 Unity developer, 1 3D artist, 1 2D artist, and a project manager.
RESULTS & FEEDBACK
Can you share any outcomes from the project that demonstrate progress or success?
In terms of important UI/UX designs, Jett was able to offer a high level of satisfaction. Additionally, they were able to refine a number of the designs to an initial MVP stage that allowed internal developers to take over. Overall, they were able to set a delivery deadline and consistently meet it while being open to fast iterating over feedback.
How effective was the workflow between your team and theirs?
Highly effective! We like to be very active in the process and believe in quick iterative feedback. Jett was very accommodating to a client that is as participatory as we are.
What did you find most impressive or unique about this company?
Working with Jett Develops is an amazing experience! They take the time to listen to your needs and are outstanding communicators. The group becomes an equal participant in your endeavor. T
hey actually care about the success of the projects beyond just their participation and don't just view them as "another job." The only reason our business will keep using them and their growing list of services are because they consistently go above and beyond!
Are there any areas for improvement or something they could have done differently?
I believe Jett has a solid team of people skilled in various areas and effective at what they do. I believe there is room for improved communication when deciding on the architecture for developing apps. That is to say, it is best to investigate the feature's objective from a development position rather than taking some UI features literally, leading to the construction of a modular architecture. This would provide the client the freedom to eventually tweak things without having to do major redesigns. With it, Jett would raise their performance to an A+.
