End-to-end product development for mobile & web
SISU is a software development consultancy that designs and builds new digital products and services.
We do much more than code -- Our interdisciplinary team combines strategy, design, and software engineering. When working with us, we’ll help you reduce risks and make the right trade-offs to maximize the chances of success, and to get you the best value for your budget.
Building the right digital service starts by tackling the right problems. To that end, we kick off our projects with Service Vision Workshops where we seek to understand and share a common vision of success for the product.
Since 2013 we've been working with our clients, from Startups to Fortune 500 companies, to help them defend, differentiate, and transform their value proposition with custom software for web and mobile.
Each year we choose to work on a select number of projects where we closely collaborate with our clients to generate value for their users and their business.
Key clients: Boehringer-Ingelheim, Credijusto, BBVA, Hightech Group, AstraZeneca, Booksnap, Segmail, Microsafe.

Decreasing untreated strokes in Mexico and Central America with Boehringer-Ingelheim
Goal: Design and develop a digital service that provides vital information to health professionals in small hospitals, clinics and pharmacies to quickly identify symptoms of a stroke and refer patients to properly equipped hospitals.
Why?
Not every hospital or medical facility in Mexico and Central America is capable of treating a stroke. There is a short timeframe to get proper help to patients and our goal was to reduce the number of mishandled cases.
Results:
- 12000+ users in the first year
- 30% searched for specific hospital information
- 0.5% called 911 from the app
- 275 hospitals on the app
Why it matters
This was an opportunity to collaborate with Boehringer as a unified team working on a very interesting challenge. They brought valuable knowledge from previous experiences and we were able to launch a successful product and achieve the project’s goals in record time.
We are really proud of the outcome, as its success means there’s an impact on thousands of lives in the region.

Validating new business ideas to push growth with Credijusto
Goal: Assess the feasibility of a referral program for strategic partners that could bring in new clients and expand their footprint.
SISU partnered with the commercial team to launch a prototype of the digital service for the program, helping them validate and track its success.
Why?
It was important to explore a potential way of accelerating growth with a low-cost prototype that would minimize risk and investment while maximizing learning.
Results:
- The first version of the prototype was released 3 weeks into the project.
- The final prototype used for the pilot with the self-generated landing pages was completed in 7 weeks.
- The budget used was on average 55% lower than traditional development methods.
Why it matters
The flexible and agile model that we adopted for this project allowed us to quickly start developing based solely on the client’s vision and the set of goals to be achieved.
The pilot program was launched in a short time and Credijusto was able to test their hypothesis, enabling them to refine, validate and rule out expansion initiatives. This resulted in great savings and risk reduction by allowing resources to be allocated to the programs with the greatest impact and that were best aligned with their growth goals.

Printing your memories: Creating photobooks in minutes, from any device with Booksnap
Goal: Booksnap sought to create a new service in the Mexican market with a friendly mobile photobook printing service that delivers to your doorstep.
Why?
For most of us, taking hundreds of photos is now a normal part of our lives, even though they almost always end up being forgotten in the cloud. Booksnap wanted to offer a service that allowed each photo to have its own story and become treasured objects to share and give away again.
Booksnap wanted to offer the experience of reliving these memories through a high quality, physical photo book that would make these pictures regain their place in our lives as treasured objects we can share and gift.
Results:
-
4.6 Star rating on the AppStore & PlayStore
-
68% sale to registered user ratio
-
+50k downloads
Why it matters
The MVP approach allowed us to obtain valuable insights that helped us make the decision to expand the service when the business was already profitable and the brand had positioned itself.
We are very proud of the service we developed jointly with the Booksnap team. The feedback from their users and glowing reviews of the app and service lets us know that all the effort and love we put into this project was worth it.

Automating complex processes to grow a shipping service with Segmail
Goal: Segmail required a management system tailored to its operation, capable of dealing with the growing size of its business.
Why?
As Segmail’s operation grew, so did the amount of information it had to manage. Doing the administrative work manually was no longer sustainable and made it difficult to continue to grow the business.
Segmail required weeks of work each month to process the information needed to figure out how much to charge each client.
The process relied entirely on complex spreadsheets and the thoroughness of its employees to avoid making mistakes or correcting them effectively when needed.
Results:
-
8x Increase in tracking numbers processed since launch
-
97% Decrease in processing time each month
Why it matters
The management system that we developed for Segmail has allowed them to continue growing their operations and take control of their business. It represented a great challenge of conceptualization, design, and development due to the amount of information that needed processing and the non-standardization in the handling of data by the different shipping companies.
We’ve also been able to prove that our work can adapt to new technologies and changes in the business environment without disrupting Segmail’s operation.

Reframing and updating an educational service for CxVet
Goal: After several years of developing and selling educational videos and materials through its website, CxVet needed to redesign its image and service to become a modern referent for veterinary consultation.
Why?
CxVet was born to help veterinary doctors who didn't have the chance to learn and practice all the different kinds of surgeries that they require in their professional practice.
Results:
- 4.2x premium accounts vs porevious site
- 28% growth in the first year
Why it matters
Developing the CxVet site allowed us to be part of the transition of an experienced business with an outdated and insecure platform that failed to attract new clients into the latest trends.
We also faced an interesting user migration challenge, both technical and strategical, that required us to offer the best user experience in order to avoid any membership loss.
The result was a successful new platform that has had an excellent reception among its users and with which CxVet has managed to reach a whole new group of clients who were previously unaware of the service.

Custom Dev & Design Solutions for Fintech Platform
"They remained efficient from the pitching to the deployment stage."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I was the head of product for a corporate-sponsored startup collections platform when I worked with SISU Technologies.
What challenge were you trying to address with SISU Technologies?
We needed their support in building a multi-component platform for our partner financial institutions.
What was the scope of their involvement?
We initially met with SISU Technologies to relay our requirements and proposed project flow to their team. Once this phase was finalized, they proceeded with building development and design solutions via Java and AWS on the backend and Javascript and React on the frontend. Meanwhile, our onshore development team solely focused on the platform's backend and UX functions.
What is the team composition?
We worked with Alejandro (Founder), a UX specialist, and two developers.
How did you come to work with SISU Technologies?
One of my friends recommended SISU Technologies to me.
What is the status of this engagement?
The project ran from March–November 2021.
What evidence can you share that demonstrates the impact of the engagement?
We hadn't measured any quantifiable success metrics as we only accomplished the product development a week ago; however, we were easily impressed with SISU Technologies' capacity to collaborate with our internal team and execute solutions that helped us meet our development goals. They also delivered well-designed and commendable functions that elevated the quality of our product.
How did SISU Technologies perform from a project management standpoint?
We finished the project ahead of our projected deadline, which spoke a lot about SISU Technologies' timeline-oriented approach. Throughout the process, we could always rely on their team to address our concerns, implement bug fixes, and stick to our budget.
What did you find most impressive about them?
They remained efficient from the pitching to the deployment stage. We got what we paid for and more with SISU Technologies' services.
Are there any areas they could improve?
There was a learning curve in our project management methods, but it was nothing that both parties couldn't fix.
Do you have any advice for future clients of theirs?
Organize weekly sprints and trust their team to deliver the results you need — SISU Technologies can even outperform your internal resources.

the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there
I’m a former project manager of a pharmaceutical company.
What challenges were you trying to address with SISU Technologies?
I was the manager of a patient's program, and the project grew more than we expected, so we needed to create an app to escalate this project.
What was the scope of their involvement?
SISU Technologies helped us design the app from scratch and made sure it was what we were looking for with this program.
What was the team composition?
There were four people involved.
How did you come to work with SISU Technologies?
The company had a list of service providers that had collaborated with before, and we found them on that list. We evaluated two different companies, theirs being one of them, and we chose them for the value proposition. They showed to be innovative and able to provide a great quality of services.
What is the status of this engagement?
We worked together from October 2016–May 2017.
What evidence can you share that demonstrates the impact of the engagement?
They did a great job; the app was disruptive, professional and they managed to create an innovative solution without losing touch with the human part and empathy.
How did SISU Technologies perform from a project management standpoint?
We had in-person meetings, presentations, and tests of the app on our phones. In terms of communication, we used WhatsApp.
What did you find most impressive about them?
They offer a great value proposition.
Are there any areas they could improve?
I don’t think there’s anything they can improve on — they were able to solve everything we needed, and we clicked with them.

Mobile App Dev for Marketing & Graphic Design Company
"The folks at SISU were what we expected. They were very professional and they delivered on time."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I'm the President of my organization called TOCA, Team of Creative Answers. We are a marketing and design company.
What challenge were you trying to address with SISU Technologies?
There was this client called Unilever who wanted more than graphic design and more of strategy. I was thinking of building an app for them and since we’re a graphic design and marketing agency, we had no developers. I then called Alex from SISU and that was my contact with him.
What was the scope of their involvement?
The app we developed was for the buyers of soap called Camay and Zest. The project calls for us to make an app for just 5–7 users — these users are considered the top buyers in Mexico, and this app would enable the seven buyers to compete with each other for a prize. I contacted SISU and they were very clear with the project. The quotation was very clear, which is something that isn’t normal here in Mexico for programmers, and the delivery was great. They were on time, and my client was very happy.
The app is to encourage top buyers to buy more products. In addition to the development, we created the graphics to show the users how many products have been bought without giving the actual numbers — since the actual numbers are private. It’s quite a difficult challenge as users can only see a percentage of their purchases and compare it to their competitors.
The application is available for both Android and iOS devices. As we are designers, we shared with SISU some screens which they used for their framework. We were responsible for the UI/UX design of the app, and they were mainly responsible for the development. They also did the follow-up when the concept was up and running.
What is the team composition?
We work with Alex (Director) and two other developers.
How did you come to work with SISU Technologies?
It was a recommendation from a friend of a friend.
What is the status of this engagement?
We started working together in 2017, between January and March, and the partnership with them is still ongoing.
What evidence can you share that demonstrates the impact of the engagement?
Well, the client was more than satisfied, and the folks at SISU were what we expected. They were very professional and they delivered on time. At first, we experienced some bugs and crashes when they were developing, but it was nothing that they couldn’t solve.
How did SISU Technologies perform from a project management standpoint?
They were perfect. They don’t use any project management tools but we mainly communicate through phone calls.
What did you find most impressive about them?
We found their initial quotation impressive and clear. I’ve worked with other vendors in the past who gave us a different fee from the original quotation. They said something like they needed more hours, or something unexpected happened. With SISU, everything was really clear.
Are there any areas they could improve?
No. I think they are perfect.
Any advice for potential customers?
I would advise that if you're not clear with what you want, SISU might help you with some solutions. For example, if I needed to know how something specifically worked, they will make it work — they will think, and they will provide you with an upgraded proposal.
