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 marketing manager for a pharmaceutical company.

We have a product for strokes. There are a lot of hospitals here in Mexico that don’t have the infrastructure to treat strokes. We wanted to develop a geolocation app so that referrals could be made to hospitals that have the needed capabilities.

They developed our geolocation web app from scratch.
What is the team composition?
We worked with four people from their team.
How did you come to work with SISU Technologies?

MVP Dev & Pilot Test for FinTech Portal
"SISU was very good in both navigating this process and in being very respectful and transparent with the cost."
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.
Credijusto is a fintech company doing asset-backed lending to SMEs that are excluded from the traditional financial system. I lead the sales operations part of the company.
What challenge were you trying to address with SISU Technologies?
We wanted to test a new partnership program. However, we didn’t want to invest internal resources, given that it was an experimental run. We were looking for a vendor that could run a lean and skeletal MVP to quickly test whether we had potential.
What was the scope of their involvement?
SISU helped us build an MVP to test the potential of our idea. We had an approximate idea of what we were looking for. We wanted to be lean and to the point. We provided some wireframes, and they turned those into actual designs, after which SISU started the actual development. They created an operational version, and we made some changes based on that. We had 2–3 rounds of iterations, after which we made it available to a pilot group of customers.
The portal we developed allows any client to request a partnership, and create their own website, branded with their logos and colors. SISU recommended building a control panel where the clients could change whatever they wanted in terms of logo, design, and name, and check how many clients had applied through their portal.
I believe the portal was built on Firebase. We used Adobe for the mockups and Mailgun for email notifications.
What is the team composition?
We worked with Alejandro (Founder). He was responsible for framing the whole project. Then, we worked with a technical person and a UI/UX designer.
How did you come to work with SISU Technologies?
We came up with two potential vendors, both through recommendations. A colleague from the sales group recommended a vendor that had done similar work, and I knew SISU from the past, but I’d never worked with them before.
We made the same pitch to both of them, in terms of our needs and what we were looking for. SISU outbid the other competitor on everything—price, approach, and estimated time for delivery—and we felt way better with them during the scoping session. They asked intelligent questions from the beginning, challenging our views. It was a pretty easy decision to make.
What is the status of this engagement?
We started working with SISU in May 2019. We had the first version by May, and our work kept going until August of that year.
What evidence can you share that demonstrates the impact of the engagement?
Adherence to the proposed timeline was one of our metrics, and they did it successfully. We were measuring the number of customers actually creating a portal and engaging with it. In the end, the idea of lead channels didn’t work out, but that was exactly what we were looking for: to check in a live environment whether we should keep going with the idea before we started investing in marketing.
We explored it with our internal base of customers. We invited 100 of them to the program, and a bunch of them created websites. There was lots of feedback and engagement, but we could never generate business through it. However, SISU did what we asked for and more, and we were very happy with the product.
How did SISU Technologies perform from a project management standpoint?
We didn’t require anything other than a few emails when needed and a few checkpoints when we had delivery milestones. It wasn’t a big project, so we didn’t need anything more complicated than that. SISU does have a system to bill the amount of time spent by the team. They billed by hours, and they knew exactly how much time they were putting into the project. Had we been given any sort of project management tool for this project, it would’ve been a waste. There weren’t that many things to follow up on.
What did you find most impressive about them?
It’s their ability to understand what the customer actually needs, and to challenge our initial vision, to build a product that’s closer to what we were looking for. We had one idea, and we ended up with something that was 10 miles from that, and it was better. SISU was very good in both navigating this process and in being very respectful and transparent with the cost. They told us when an option would lead to 30 hours more work, for example, and it was up to us to decide whether we did it or not. They were very transparent, and it was a very good execution overall.
Are there any areas they could improve?
I don’t have anything in mind. SISU performed well, and I have no complaints in terms of pricing or transparency.

Android App Development for Metal Manufacturer
“They were clear and precise with all of their deliverables, and everything was provided formally and professionally.”
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 am a general manager at MicroSafe in Mexico City.
What challenge were you trying to address with SISU Technologies?
We have developed different solutions for security and cash management and worked with them to help us lay out the requirements and plan for those projects.
What was the scope of their involvement?
The first part of our work together involved workshopping and more precisely defining our roadmap for a large and complex development project. We needed to establish requirements for a payment kiosk that we were trying to provide to fast service restaurants in order to eliminate a significant amount of risk in the project both budget- and time-wise.
We sat down together and really went into detail about what needed to be done and what constraints we had on our side so that we could formalize those in the form of expectations with our client.
After that, they helped us to develop an Android application for one of our particular solutions that served as a smart locker. It allows delivery and secure pickup and uses a mobile app that they helped us develop.
What is the team composition?
There were three individuals on their team that we interacted with, including a general manager and two developers, one of whom functioned as a project manager as well.
How did you come to work with SISU Technologies?
I had a pre-existing relationship with the founder of their company, so I knew they had been working on some interesting projects and had really solid development skills. We chose to work with them because of their portfolio as well as our confidence in their work ethic and reliability.
What is the status of this engagement?
The two projects ran from February 2019–March 2020.
What evidence can you share that demonstrates the impact of the engagement?
The biggest value that we got out of the first project with them was that we were able to deploy a working MVP with our client that didn’t overshoot the budget or timeline of the engagement.
Throughout all of our activities with them, they have been totally professional, and we’ve always gotten what we expected if not more.
How did SISU Technologies perform from a project management standpoint?
Since we were working for a third-party client, they were able to act as an incredible mediator, not only between the two teams but between our development team and more business-oriented teams in order to help them understand and respect the constraints that the other teams were under.
We could go back to the documents that we laid out in the project and use them to keep things under control and on track if there was ever disagreement further down the line. They were clear and precise with all of their deliverables, and everything was provided formally and professionally.
What did you find most impressive about them?
The fact that we were able to do that on a project that involved hardware and software over the course of a year or more was absolutely incredible, and without the definitions workshop I’m not sure that we would have been able to do it.
Are there any areas they could improve?
No, we’ve been quite satisfied with the quality of their work so far.
Do you have any advice for potential customers?
Scope creep is a recurring problem in a lot of development projects here in Mexico, so I would recommend more people engage in the kind of workshop we had with them. It is a really different and better way of doing things from what we were used to.
