Describe the scope of work in detail. Please include a summary of key deliverables.
Calda Calda did an amazing job turning our idea into a real app we can use, called Client Keeper. In the beginning, we had meetings to figure out what the app really needed to do and how long it would take to make it. Calda was really careful to only include the most important things in the first version of the app, so we didn't spend money on stuff we didn't need. Next, we worked on making the app look good and easy to use, which is called UI (how it looks) and UX (how it feels to use). This took the longest time because changing how the app looks after we start making it is hard and expensive. After about 3 months of focusing on the UI and UX, we started actually building the app in early 2024. This part was easier for me because we had already made all the big decisions. By early March 2024, anyone could download our app from the App Store! Plus, they made a Web App that was for admin and data management :) Every week, the team making the app and I would meet to talk about how things were going and what we needed to do next. We made sure everything that needed to be done, got done.

The thing that I appreciated the most was how they mapped the whole process for me and made sure I was aware of time frames and pricing. Everyone has been on the same page since day 1. They do not mind having "tough conversations" meaning if they see a better way to design they will tell you especially when it comes to long development cycles and a lot of money. They want their projects to be amazing, on budget, and on time.

Nope! It has been great!

Describe the scope of work in detail. Please include a summary of key deliverables.
I hired Calda to develop a mobile application, which would allow our app users to order their food online in-advance to later pick up in the restaurant. The other important feature was to set up a loyalty system that allows users to be rewarded for their continuous purchases. The system had to be easy to manage for the customer (as little input from them as possible).
Overall, Calda approached the project professionally and with great care. We started the development by defining the key features and then followed up with UX wireframes. That was followed with UI design (which I was very satisfied with!) and then the development of the backend. App was developed in Bravo studio (frontend) and Supabase (backend), which allowed a quick development process, which was key for me and my business.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
A great mobile application, which helped my business to channel online orders from 3rd party platforms to our own sales channel, which allowed greater profitability. We also saw great rise in recurring buys, because customers seemed to love the loyalty system. Overall the app helped my business make more money. And Calda made sure that the process was quick and efficient, which was of utmost importance to me.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
I felt like I was a part of the development process throughout the whole time, which was not my experience when working with other software development teams in the past.
They did their best to keep the communication thorough and constant with a dedicated Slack channel, weekly recurring meetings and access to their tasks kanban board. They also dedicated a project manager to my project, who made sure that I was always updated and my wishes were met.

What did you find most impressive or unique about this company?
The Calda team was fun to work with. They cared about helping me build the best prototype possible, and advised me when they thought a tool could do a better job than what we may have initially planned to use. I remember early on the process they suggested using a different back end tool than the one they first suggested, because it would allow me to capture data from a larger group of customers.
Are there any areas for improvement or something Calda could have done differently?
Because I was referred to Calda they wanted to be good partners and recommend using the no code app development tool of the company that referred me. Although there may have been another tool that would have met my needs slightly better. I can’t fault them for that. I wish there was a way to see what other options and tools they have worked with so that I could compare those tools before making my decision.

I’m the founder and CEO of Superplan, a financial services company that provides AI for financial advisors.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Calda?
We needed help building our MVP.
SOLUTION
What was the scope of their involvement?
Calda has been helping us with FlutterFlow development, backend development, and AI integration. The main deliverable is an end-to-end platform for financial advisors, which includes document ingestion, data structuring, and report writing. We encountered lots of unknowns that appeared as we built the functionality, especially with FlutterFlow’s limitations with Postgres and AI, but we managed to overcome all of them.

What did you find most impressive about them?
We’ve been building our product with Calda, and they’ve been a great partner throughout. The team is solid across FlutterFlow, backend work, and AI integration. However, what stands out the most is how they think like builders. Calda doesn't wait for perfect specs; they get stuck in, figure things out, and keep moving.
Moreover, the team is easy to work with. They’re flexible, collaborative with other teams, and supportive of us as founders. Overall, they’re genuinely good people who care about the work and the journey. I highly recommend Calda.
Are there any areas they could improve?
There’s nothing I’d have them improve.

"Strong across FlutterFlow, backend, and AI - but more importantly, they move fast, figure things out, and care about building good stuff. No waiting around for perfect specs - they’re hands-on, curious, and solve problems as they go. Highly recommend."
