Synergy Captuvo

*Synergy Captuvo* is the mobile implementation of the Synergy sales tool.

OneClick needed to hire a team with expertise in mobile development. They've already had a big number of clients and implementing the mobile part of their system  was a must. The Synergy system allows organizations to handle sales and purchases done on their daily operations in an orderly fashion, giving total transparency to all the parties of

the company.

We implemented the mobile part of their software which requires the use of the Captuvo® cradle which adds to the mobile phone the capacity to scan barcodes and allows it to read credit cards.

We took over the development process and built a solution which was customized to three of Synergies customers, in order to add mobile sales points, payment generations and stock control features into their processes:

Key challenges
• iOS App (Objective-C, Swift, Realm DB, Unit Testing)
• Moving big volumes of data from server to client
• Implementing bardcode reading hardware capabilities
• Test and generate a bug-free version of the software

PontaMedia creates innovative digital marketing solutions.

They need a technological partner to help them build BrandCaptcha, a CAPTCHA AdServer Platform that provides services for Publishers and Advertisers, in order to connect brands with users.

Instead of having to decipher illegible codes, users must enter a brand message in the “Answer” field. Thus they

validate that they are human and not bots.

Zarego became a main actor and finally took over full management and development process.

Working continuously side by side for over 18 months, today more than 30 agencies, 80 brands
and 500 publishers are using BrandCaptcha services, solving 10 millon daily CAPTCHA Challenges.

Introduce your business and what you do there.

I’m the CEO of PontaMedia, a company that develops technology for the digital advertising industry. We started developing our product in mid-2013 and it was launched in the first quarter of 2014. We’ve worked with more than 100 brands over the last five years, including Fortune 500 companies. They’ve all chosen our company for advertising their services or products in a unique and innovative digital format.


What challenge were you trying to address with Zarego?

When the company was founded, we made a prototype of our BrandCAPTCHA product and managed to raise some money. We needed to take it to the next level, so we went to Zarego for advice and help with developing this service. Our company didn’t have a tech team or a CTO, so they’ve played this role while going through the transition from the prototype to the product we launched.


What was the scope of their involvement?

Our product determines whether users are human or robots through the use of a captcha. This includes users interacting with registration forms, surveys, or anything else that requires validation. We came up with the idea for users to interact with advertisements, as opposed to traditional captchas that work with distorted words or letters. Instead of typing an ancient English word scanned from a book, they now have to type in the color of a car, the discount offered by the car company, or whatever the advertisement wanted to communicate to the users.

We needed to accommodate the increasing demand of ads we were receiving. We had big opportunities with telecommunications companies and banks using BrandCAPTCHA, so we needed to go from a hundred thousand to a hundred million captchas per month. Zarego took a few weeks to see the big picture and finally told us to start over from scratch since the prototype wasn’t ready to be transformed into a real product.

They recommended using AWS for the scalability it offers as well as its other useful features. We started creating an architecture there that could handle all the volume we would be having with the telecommunications companies. Zarego was very involved from the first moment they took the project on. They didn’t just think about solving the present problem but rather approached it as a long-term vision and solution.

What is the team composition?

We worked with four of them in the beginning. A few developers left the company, so I believe we were working with 2–3 of them towards the end. Zarego handled all project management. They acted as our CTO for the first year and we outsourced everything technology-related to them.

How did you come to work with Zarego?

One of our partners—our first seed investor—knew them from years ago and considered them capable and trustworthy. He told us that we needed to give this project to a company that could take it to the next level. We met Zarego in 2013 and we trusted them from the beginning.

How much have you invested with them?

I would say we’ve spent $70,000–$100,000 with them.

What is the status of this engagement?

We started working with Zarego in September 2013 and wrapped up around July 2015. We later took all the work in-house by hiring a CTO and a senior software engineer.


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

In our first year, we had close to 100% uptime. We went from 100,000 captchas served in that time to almost 10 million. More than 20 million people have interacted with our captchas since we started and we’ve run more than 100,000 campaigns on the platform Zarego created, with more than 100 brands. We currently have almost 100 million impressions every month.

All of this was built on the foundation Zarego provided. The architecture is still on AWS and we’re working with the servers we procured back then.

We had a nonverbal service level agreement with them stating that they would intervene whenever we had a bug or a small crash. We didn’t have any problems in the first years, but if something happened, they had different response times depending on the level of importance. Since we didn’t have an in-house CTO, we needed them to give us solutions fast. Their team always responded very, very quickly. They knew that if we wanted to run a campaign for a client, we couldn’t take a week to solve a problem, so they were always available for us.

How did Zarego perform from a project management standpoint?

Zarego did an excellent job. We were very happy with them and we still meet with their team every now and then. We started working with them in 2013 and we’re still looking for new projects to do with them five years later, which speaks for itself.

We didn’t use any project management platforms, only Google Drive, email, and phone calls.

What did you find most impressive about them?

They were sincere and straightforward when providing solutions, but they also listened to our opinions. They know where their strengths supplement a client’s lack of skills. When I explained to them how something on the platform should be developed, they’d kindly tell me what the best way to do it would be based on their experience.

Since I’m not a technical person, I didn’t get involved in the details of the development but rather let them do what they did best. Furthermore, I’ve always appreciated that they were sincere with time estimates and provided precise timelines. They didn’t promise to complete a task in one month if they knew it could take three.

Are there any areas they could improve?

I don’t have any specific criticisms. I believe the company needs to grow and offer their services to more people, but it’s their decision whether to expand or continue being a boutique software development company. I know that they’re skilled in what they do and they’ve worked with a lot of clients.

Do you have any advice for future clients of theirs?

Clients should just talk to them; they’ll see that Zarego has great skills for transforming an idea into a product. Their team will work on as if they were part of the company, not just a service provider. Go ahead and start working with them as soon as possible!

Overall Score One should always have room to improve, but I’m giving them a five because I’m happy with them.
