Project Description — Stage 1: Design and Build of the Monetr App for Simplified Reporting in Small Businesses

The first stage of the Monetr project focused on the design and development of a web-based application that enabled small businesses to track, visualize, and share key performance indicators (KPIs) without the complexity of traditional reporting tools.

During this stage, Acid Tango delivered an intuitive, no-code-style interface that allowed users to:

• Create and customize KPIs aligned with their business goals across sales, operations, and finance.
• Manually enter or import data from spreadsheets or integrated systems.
• Visualize performance through automatically generated graphs, percentage changes, and trend insights.
• Collaborate with team members via comments, shared dashboards, and simple reporting tools.

The primary objective of Stage 1 was to build a minimum viable product (MVP) that validated Monetr’s core value proposition: making data-driven decision-making accessible to smaller companies that lack dedicated analytics or BI tools.

Key deliverables achieved included:

• Core app design and user experience (UX/UI).
• KPI creation and reporting workflows.
• Manual data entry
• Visualization components such as line charts, trend analysis, and sharing options.
• Basic user accounts and permissions.

This initial release laid the foundation for future development.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

Key Success Deliverables — Stage 1

• Functional MVP delivered — A working application demonstrating Monetr’s core purpose: simplified KPI tracking and reporting for small businesses.
• User-friendly interface — A clean, intuitive UX/UI allowing non-technical users to create and view KPIs without setup complexity.
• KPI creation and management — Full workflow for adding, customizing, and organizing KPIs across Sales, Operations, and Finance projects.
• Manual data input — Secure workflow for direct data entry.
• Dynamic visualizations — Automated charts and trend indicators (line graphs, percentage change, comparisons) for quick performance insights.
• Collaboration tools — Commenting and sharing functionality enabling simple internal reporting and discussion.
• User authentication and access control — Basic account setup and role permissions implemented for secure use.
• Technical foundation for expansion — Solid architecture prepared for SDK integration, automated data collection, and AI-driven KPI recommendations in future stages.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Delivered on time and project requirements were met.

What was your primary form of communication with Acid Tango?

• In-Person Meeting
• Virtual Meeting
• Email or Messaging App

What did you find most impressive or unique about this company?

We worked with Acid Tango on the first stage of the Monetr project — the design and development of our MVP for simplified reporting in small businesses — and found the experience extremely positive.

They were highly professional, showing strong technical expertise and excellent communication throughout the process. They were open to new ideas and showed genuine interest in understanding our vision, often suggesting thoughtful improvements that strengthened the final product.

Their organisation and project management were standout qualities — milestones were clearly defined, progress updates were regular and transparent, and delivery remained on schedule. Overall, Acid Tango proved to be a reliable and collaborative partner, and we would not hesitate to recommend them to others looking for a capable and well-structured development team.

Are there any areas for improvement or something Acid Tango could have done differently?

While our overall experience with Acid Tango was very positive, we felt that their involvement in post-release testing and user validation could have been stronger. Once the initial build was delivered, we would have appreciated a more proactive approach to refining the product based on real user feedback. As this stage of testing and iteration is critical to our roadmap, we decided to take a different direction for the next phase of development.

BACKGROUND

Introduce your business and what you do there.

I’m the co-founder of DESCIFRA, a map infotech company. We help business owners create strategies using maps.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Acid Tango?

We wanted to redesign our whole UX/UI from scratch.

SOLUTION

What was the scope of their involvement?

Acid Tango designed the customer journey by coming to understand how our customers use our previous platform. They then mapped all of that into a new design for the whole platform. We originally thought we wanted to update the existing one but it turned out to be a better idea to redesign it from scratch. They helped us implement an agile scrum way of working. They used Zeplin and Illustrator.

They built widgets and the capability of selecting maps. They helped us develop more on the frontend side but they also helped on the backend side.

What is the team composition?

We worked with four people from Acid Tango most of the time.

How did you come to work with Acid Tango?

We were looking for an agency in Mexico and we weren’t able to find one right away. Out of the blue, they sent me a message on LinkedIn. They looked good so we decided to work with them.

How much have you invested with them?

We have invested $80,000.

What is the status of this engagement?

We worked together from February–July 2020.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Our customers thought the platform was fantastic and easy to use. We got a lot of good testimonials.

How did Acid Tango perform from a project management standpoint?

We used Monday and Slack to collaborate. Project management was great. Internally, we didn’t work with any particular methodology but they helped us go into scrum and agile.

What did you find most impressive about them?

The quality of their work was excellent. Their willingness to complete the project despite the budget limitations was quite notable.

Are there any areas they could improve?

We were happy with Acid Tango's work.

Do you have any advice for potential customers?

Make sure you have the right scope of work that you want to do because it’s not cheap. You want to make the most out of your time.

BACKGROUND

Please describe your company and your position there.

I am the CEO and co-founder of Happets, a premium subscription service for customized pet food. It handles the entire fulfillment and delivery process from picking and packing the product to shipping them off to the home of the consumer.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Acid Tango, and what were your goals?

We hired Acid Tango to optimise and scale Happets' back office, add new functionalities to our platform, and improve the performance of the home page.

As a funded startup in need of rapid growth, we had to be able to swiftly implement lots of requirements in our platform.

Since this could not be covered by hiring people at that point, we looked for skilled and experienced developers matching our needs.

SOLUTION

How did you select Acid Tango and what were the deciding factors?

We considered several providers, but chose Acid Tango because of a personal recommendation. We decided to go with them due to the speed and expertise they were able to provide.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

The project involved improving our back office, which had been developed in-house, to encompass a wide variety of functions, many of which were interlinked. Acid Tango added new functionalities related to the subscription model management, orders management, and customer service support mainly.

They also maximised scalability in the back office, eliminated most manual data entries, and redesigned the platform so it could be more usable. Finally, they carried an A/B testing to monitor the performance of the home and the checkout page.

This led to the optimisation of the user experience implementing new design features and custom functionalities. Other functionalities incorporated included the user log in, profile, ingredient specifications, order tracking among others.

How many people from the vendor's team worked with you, and what were their positions?

They assigned us a dedicated project manager, and a team composed by 3 front-end developers, 4 back-end developers and 2 UX/UI designers.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

Our team found the process much easier to fulfill as a result of the new features included and the manageability of the back office. It made the company scalable.

Describe their project management style, including communication tools and timelines.

The team was always very engaged when it came to finding a solution for complex problems and the workflow was highly efficient.

What did you find most impressive or unique about this company?

We were impressed with the diversity of the skills. They held and their commitment to our project as if it was their own.

Are there any areas for improvement or something they could have done differently?

There’s always room for improvement, but I’m happy with what they’ve been able to do, I don’t have any complaints.

BACKGROUND

Please describe your company and your position there.

Exolum, a new company from CLH Group, its mission: push new sustainable business opportunities that preserve the environment. We want to be a lead agent for change that contributes to society creating viable green projects based on the transformation of infrastructures.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Acid Tango?

We wanted to develop a secure and technological parking network for trucks, where the operation of the facilities could be managed from an App for our customers.

What were your goals for this project?

Our goal has been to allow users to enter the parking facilities in an agile, comfortable and safe way through their mobile devices.

SOLUTION

How did you select Acid Tango?

We met AcidTango through a common contact, and after reviewing different proposals, we found that their business philosophy was similar to ours.

Describe the project in detail.

Customers use the parking autonomously to access and leave the facility, but also to make reservations on a one-off basis (as if they were a hotel). A booking system had to be created to analyse availability and manage occupancy in real time. Access is done through a double check that reads the vehicle's number plate and an smart QR reader to validate entry and exit.

What was the team composition?

On our side, we had 3 different profiles assigned to us. On the Acid Tango side, our main interaction was the project manager, but there were different profiles adapted to the following needs: graphic design, iOs development, back-end development, front-end development, user experience, etc.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Although we are still validating the business model, you can download the Yubick app on both iOs and Android in their respective stores.

How effective was the workflow between your team and theirs?

Communication was quite fluid with daily and weekly meetings. In addition, we used Slack to communicate easily all the time.

What did you find most impressive about this company?

Their synergy with our company and ability to develop in a lean way were impressive.

Are there any areas for improvement?

We believe that more flexibility in the customer relationship model would be helpful.

BACKGROUND

Introduce your business and what you do there.

I’m a product manager at Wondo Mobility, a three-year-old Spanish startup. We’re part of Ferrovial Group, one of the biggest companies in Spain, working on highway infrastructures and things like that. Our startup aims to give citizens of Madrid, Barcelona, and other cities of Spain different possibilities to move around their cities, by car, scooter, and so on. They can also use our app to pay for public transport and taxis.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Acid Tango?

We started small three years ago, and we were thinking about getting bigger and adding integrations with more mobility operators. Our main focus wasn’t technology, so we wanted a partner that could help increase our development quality and speed, in order to go to market as soon as possible.

SOLUTION

What was the scope of their involvement?

Acid Tango has worked with us in two main areas: backend integrations between our system and operators, namely the companies that own cars and scooters; and client application development.

The app is built on React Native, which enables us to deploy the same code on iOS and Android. Acid Tango is also developing our website, and they’ve helped us with UX design.

What is the team composition?

We have seven developers from Acid Tango working with us, both frontend and backend. They’ve assigned us UX developers as needed.

How did you come to work with Acid Tango?

We attended South Summit, a large event in Madrid for innovators and startups. We were presenting our new application there, and we began talking with Acid Tango about what they did.

How much have you invested with them?

We’ve spent more than €200,000 so far (approximately $240,000 USD).

What is the status of this engagement?

We started working with Acid Tango in December 2019, and it’s ongoing. We hope to work with them in the long term.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’re really happy with Acid Tango. They’ve helped us increase not only the speed but also the quality of development. They integrated well into our development and design teams, and they’re very proactive people. They’ve given us a lot of new ideas on technologies and ways of working.

We gained 60,000 users in one year. We launched in September 2019, and we were going very slowly. Acid Tango started with us in December of that year, and we increased our user count very fast after that.

How did Acid Tango perform from a project management standpoint?

We all work with Slack, and we use Jira to log issues and tasks. We also use Confluence, and we use Figma and InVision for design.

What did you find most impressive about them?

They’re very proactive people, and they always come up with new ideas to test.

Are there any areas they could improve?

I always tell them to hire more people. Acid Tango has good expertise in mobile applications, but they could always improve in terms of marketing and getting us more downloads.

Do you have any advice for future clients of theirs?

I’d tell them to give Acid Tango an opportunity. We started very slow with them, to see if it would work out.

BACKGROUND

Please describe your company and your position there.

I belong to an small IT consultant company and I'm in charge of the AI department.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Acid Tango?

We hire Acid Tango because we needed to design the dashboard of a Reputational Risk software.

What were your goals for this project?

The Reputational Risk application interface needed to be very usable and self explained. Because the data showed were not easy to understand, the UI/UX was a key point in the road map of the project.

SOLUTION

How did you select Acid Tango?

Because we liked some of the projects where they work before.

Describe the project in detail.

The project was basically the design of an interface for a reputational risk measurement software. The concept of this program is complete new and difficult to understand, so it was mandatory to build a dashboard that helps the user to work easily with the data.

What was the team composition?

The team was composed by a coder and a UI/UX designer.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Acid Tango made and excellent work on designing the user interface. That was one of the key points for the success of the application. Most of the clients were impressed by the features they designed and code.

How effective was the workflow between your team and theirs?

They workflow was quite effective and we have no problems on discuss/sending ours specs and have feed back fluently.

What did you find most impressive about this company?

Their creativity and understanding were great.

Are there any areas for improvement?

Always, I would say that the code was not very structured and clean. Probably because we were on a rush to finish, but they didn't use components.
