      Mobile App Development Review from Angie Tromley-Morales, PMP

      We hired Empat to design and build the MVP of House Caddy, a household management app that keeps receipts, warranties, manuals, and repair history in one place, with reminders for expiring warranties and maintenance. The product also helps homeowners prepare a full digital home history for future property transfers.Empat delivered end-to-end work: discovery, UX/UI design, Flutter mobile development, and a Python backend. They implemented a clear flow where users first create home appliances/systems and then attach documents and repairs to each item.A major highlight was Empats AI expertise. AI features simplify the entire user journey by auto-filling appliance details from photos/docs/links, assisting with utility provider setup, and importing contacts to speed up adding contractors. This reduced manual input and made onboarding fast and intuitive.Communication was excellent, with proactive brainstorming, clear sprint updates, and on-time delivery. The MVP is market-ready, early feedback is very positive, and Empat proved to be a reliable, product-driven partner with strong mobile, backend, and AI capabilities.

      Mobile App Development Review from MaryRuth Ghiyam

      Kaizen Apps is developing a mobile app for us. We provided information to jump start the project, and they gave us samples of similar projects they've done to give us an idea of what to expect. They provided a detailed scope of work that was over 100-pages long. We had several exchanges back and forth to tweak requirements for a few weeks. Our respective lawyers also looked over the scope. After the scope was approved, the team got into the project launch and began the design phase. The team started with a low-fidelity design and built swim-lanes. After that, they moved into high-fidelity design, which they're about to finish.Additionally, the Kaizen Apps team provides us with consultancy services to help us grow the app. For example, they've advised us on handling customer service and tools we can use to help with that aspect. They've also connected us to other parties that can help us.

      Web Development Review from Vadim Kagan

      Our company hired Kaizen Apps to develop our site backend database and front-end. They did a fantastic job. The site was fully coded, from start to finish. It wasn't on WordPress, wix, etc. It also needed to contain a database. There were so many guidelines to follow that I was impressed that each was fulfilled with ease. I was impressed by the ability of receiving a fully working site and also having received SEO & Google Ads setups. An all-around company.

      Web Design Review from Kenneth Barrett

      Kaizen Apps provided a full redesign of our website and recreated it in WordPress in a fashion where we can easily make changes without them. Website redesign included homepage development, some coded items to reflect our framework, design ideas to display unique value propositions and many solutions page. The team was responsive and delivered in a timely fashion when we wanted launch to be beginning of the year. The website redesign as offered us a fresh look to reflect our updated solutions/services. It has also helped us on the backend to easily make some changes ourselves.The quick-turn around on requests and design items. Also Kaizen Apps availability to hop on a call - which at times was late at night when we were trying to meet a deadline. Very flexible and their team was committed to pulling it which exceeded my expectations. Kaizen Apps is also very clear on what is feasible, what is not, and price points accordingly - straight shooter - which was very helpful as we were developing ideas.

      Branding Review from Andy Dickhut

      Ive had the opportunity to collaborate with numerous creative agencies throughout my career and BayCreative has delivered the level of insight, professionalism, and genuine partnership that I have experienced with the best of them. They have been true collaborators, invested in CFCUs vision and committed to helping us bring it to life.Our relationship with BayCreative began when we sought to undertake a full-scale rebranding initiative. CFCU has always prided itself on serving our community with a people-first approach, but we needed a refreshed identity that reflected who weve become and where were heading. We didnt just want a new logo or a new color palettewe wanted to redefine what Community First stood for in the modern financial landscape. BayCreative understood that right away.From the earliest discovery conversations, the BC team listened carefully, challenged us thoughtfully, and helped uncover an authentic narrative at the core of our brand. They guided us not toward trends or gimmicks, but toward something enduring and true to who we are.They have a team of talented creatives who brought our new brand identity to life. From graphic designers to copywriters to video editors, the BayCreative team demonstrated deep expertise. The final deliverables included a refreshed logo, a full identity package, and a bold new brand positioning platform we now call The New Local. This wasnt just a tagline or a sloganit was a strategic redefinition of who we are and why we exist. If you are looking for an agency that will take the time to understand your organization, push your thinking in productive ways, and deliver exceptional creative with professionalism, I cannot recommend BayCreative more highly. They are the real deal!
