We are a nonprofit advocacy organization whose mission is to end hunger globally. Our team was going through significant changes and transitions related to staff capacity, website migration and redesign, systems migration, and change in branding and messaging.

OST helped us go through this very rocky process by managing our tech stack: website management, microsite creation, web hosting, and analytics. We received bids from multiple vendors and decided on OST because of their breadth of experience and high reviews. After the initial call with Manish, it was clear he and his team had the right experience, skills, and disposition.

We found huge success working with OST. They were integral to helping us with multiple ongoing projects: website CMS, redesign, messaging, rebrand. Very effective workflow. Very responsive. Fully engaged, with quick turnaround on our asks no matter how small or big.

I have been very happy with them, which is why I have kept them on for years.

We are an online medical information business that lists health professionals located in Cyprus. We needed help with web development and creating the database, plus weekly and monthly extra tasks, features, and modules added to the website.

Patients gave very good feedback about the look of the site as well as the usability. The main focus was to make it user-friendly so that people of all ages could use it, and we achieved that. Any issues that occur are fixed within 24 hours. They were very responsive. Communication was very good between the project manager, the technician, and me.

I have been very happy with them, which is why I have kept them on for multiple years. If something critical comes up, they take care of it. They offer weekend coverage. Communication is the most important, as well as responsiveness and knowledge.

I feel like I'm their only client.

I own Bango Systems, an e-commerce company that sells wholesale goods all over the country on a custom-developed OpenCart platform. We needed functionalities the previous developer couldn't handle, including scraping a supplier with millions of products, pulling relevant data, and updating our site every couple of days.

OpenSource did tons of engineering work to set up two separate servers to pull in all of this information, do the backend work, and post it on our site. It was a huge project, and they pulled it off flawlessly. Before working with them, we were doing $25,000 to $30,000 per month in business. Now, we're doing well over $90,000 per month.

To say it as simply as possible: I feel like I'm their only client. When I send a message or call, they immediately respond and handle whatever I'm asking for. They project plan within hours, not days. Their answer is always yes. They always come in with a reasonable quote.

OpenSource Technologies had an amazing way of solving virtually any issue.

I'm the founder of a bullying prevention program for K-12 schools. We wanted to build a bullying reporting software that would allow kids to submit reports to their school in a secure database. The program then alerts school counselors, who can follow up and investigate each incident.

Working with OpenSource Technologies has helped me refine and develop which products I can offer schools. The backend and reporting side are hosted on a responsive WordPress site. The team developed the whole database, which has the capacity to import lists of schools' student bodies and track related reports throughout the year. The user feedback was overwhelmingly positive.

OpenSource Technologies had an amazing way of solving virtually any issue that arose. The communication process was always smooth and easy. They never dropped the ball. I appreciated how well they understood my project from the user perspective, especially the emotional layer of bullying prevention software. International developers often over-promise and under-deliver. OpenSource Technology really did the opposite.

We manage and operate five different corporations in different industries. We started our relationship with OpenSource Technologies when trying to start a mobile app for 27th Investments for our investors and clients to have access to information. They moved into website design and setting up servers.

Their team built an iOS and Android app, full-scale: from design to client interaction, all UI and UX, and publishing through the iOS App Store and Google Play. After the app was running, we started working with their marketing department as well.

We did a lot of in-house testing and the app functioned how we wanted it to function. They also did a great job with the website, which had a more complex backend. Some issues came up, but they immediately fixed them. Their knowledge of technology and ability to communicate were impressive. There's never been a question of whether they could do the work.

OpenSource expertly follows best practices and has phenomenal customer service.

We're a solar installation contractor that also sells product throughout the United States, Puerto Rico, Mexico, and Canada. Another company developed a shopping cart for us on the OpenCart platform but couldn't adequately service us. We needed someone else to take on the project.

OpenSource has done a great job of fixing most of the previous issues. In addition to the shopping cart work, they also do our SEO, and we've been pleased with the results. We found out that our credit card processing company didn't have a plugin for OpenCart, so OpenSource went to create the custom plugin.

OpenSource put together a highly detailed proposal that clearly outlined what they would need, what they would do, and how long it would take. We've definitely noticed a change in our website traffic. They're incredibly responsive. OpenSource expertly follows best practices and has phenomenal customer service. Their business model is organized and professional.

We sell commercial hardware online throughout the United States. OpenSource Technologies updated our existing website to the new OpenCart version and migrated it to a new server. The ongoing partnership has been limited to backend development.

The experience was stressful, but they were professional and pushed through the hurdles. We're happy with the team and continue to use them. The team provides responsive service in a timely and professional manner. We usually have teamwide emails, calls, or Skype.

OpenSource is very knowledgeable in many areas. We've used them to develop our website, add Google reviews, do SEO keyword work, and run our email system. The team's strong communication skills distinguish them.

They showed us that they know what they're doing and have e-commerce experience.

We are an e-commerce startup, Tenelo.shop, that specializes in South American markets. Our company operations are in Shenzhen, but our market is in Uruguay. Our current IT team isn't familiar with OpenCart, which is why we went to OpenSource Technologies.

There is a huge difference in the before and after pictures of our website. A lot of the current features are not even close to what they were in the beginning. They have delivered everything that I've asked for. Every time we needed to change something, OpenSource Technologies responded immediately with three or four options.

OpenSource Technologies met all of our deadlines and expectations. If I contacted them about something I wanted to change, even if it was at night or on the weekend, they would have an answer for me within a few hours. If they don't know something, they investigate and give me an answer within 48 hours. This is rare. I'm not used to working with companies that are so professional.

OpenSource had someone who was up earlier and up later to fit my needs.

We're kind of like Kosher Amazon. We have our own warehouses and do 1-hour free delivery to all of our customers through our mobile application on iOS and Android. Once a customer makes an order, our drivers pick up the order and deliver within one hour.

We launched in February 2017. It was very successful. We had one time when PayPal didn't work and they were all sleeping. I called Manish and within 5 minutes it was back up. We haven't had any reports of crashes. We have over 1,000 downloads overall.

There's a 10-hour difference. They had someone who was up earlier and up later to fit my needs. The project manager was very good, very knowledgeable. They have a lot of experience. What's amazing is I gave them a small deposit and only had to pay them after they finished the work.

I am the development manager for an online jewelry portal. I was looking for a trustworthy company that could build our website, which can be a challenge to find in India. OpenSource Technologies developed our website with elements like a dynamic banner that disappears when users scroll, zooming for our product pictures, and more.

Compared to the other companies we contacted, who promised to offer the cheapest and best solution, OpenSource Technologies could actually deliver what we needed. We received all the functionalities we asked for. The agency understood and met any deadlines we had.

I appreciated OpenSource Technologies' personal touch. They put it on all their work.
