A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the president of an innovation product company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Semaphore Mobile?
We needed a software platform to work with a product we were developing for Amazon.
SOLUTION
What was the scope of their involvement?
They created the platform from scratch. It was a web and mobile application for iOS and Android, and they integrated everything into the chips that we use for the project. The product interacts with Amazon's Alexa, so it's a cross-platform system between Amazon and our clients to deliver information back through our product. The entire project is unique in our industry.
What is the team composition?
We worked with a team of three, and our main point of contact was one of their company heads.
How did you come to work with Semaphore Mobile?
We interviewed a number of companies. Semaphore's depth of understanding and overall grasp of the total project was very impressive. Ultimately, that's why we selected him.
What is the status of this engagement?
We started in 2017 and worked into 2018. We had a five-month development period before we fully deployed.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Our main markers for the project were implementation and a successful rate of functionality. The product operates well and we've received positive comments from users.
How did Semaphore Mobile perform from a project management standpoint?
Their project management was particularly strong, and they did extremely well throughout the process. Most of our communication was through in-person meetings and email. We also shared links to documents and other parts of the project.
What did you find most impressive about them?
Their global understanding of our mission and their ability to see the project through to fruition both stood out.
Are there any areas they could improve?
They’re great, and I really don’t have anything they could change. They worked all hours of the day or night, and we couldn’t have achieved our goals without them.
Do you have any advice for potential customers?
Spend the time you need at the beginning of your project and collectively develop your expectations.

A Clutch analyst personally interviewed this
client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
We’re a software development company focused on building an e-commerce product.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Semaphore?
We didn’t have the required on-site staff to develop new features for our web-based platform.
SOLUTION
What was the scope of their involvement?
Semaphore worked on several features, including a quotation system and order fulfillment functionality. They used Ruby on Rails and JavaScript. They did not provide any frontend design.
What is the team composition?
Semaphore assigned three senior developers and a project manager (PM). An architect was also available. We didn’t really need the PM, as we could manage our own staff.
How did you come to work with Semaphore?
I found them online and gave them a call. I started a conversation with Eric (Owner, Semaphore Mobile), and we hit it off. We kept in touch over time, and I reached out to them when I needed help.
How much have you invested with them?
The cost of their work was around $20,000.
What is the status of this engagement?
We worked with Semaphore from January–November 2018. The application is fully deployed.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
We tracked their quality through a weekly code review. It took us a few reviews to let them know how we wanted things to be done, but this is to be expected with every project. Once we got past this, they were able to meet our standards.
How did Semaphore perform from a project management standpoint?
It was pretty great. We shipped code quickly, with the average deployment time being two weeks. Our main forms of communication were phone and email. We also had Skype meetings when needed. They responded well to our feedback.
What did you find most impressive about them?
We sometimes get the bait-and-switch with development companies, but I never saw that happen with Semaphore. They stand out just by being straightforward.
Are there any areas they could improve?
They addressed all the issues that I brought up.
Do you have any advice for future clients of theirs?
It’s always wise to know exactly what you want before engaging a development company.

Describe the scope of work in detail. Please include a summary of key deliverables.
We had an app built by our local team. However, development had come to a stand-still due to lack of manpower. We enlisted Semaphore Mobile to take over the app development from where the code existed. This required a major update due to the age of the application. After the first release that brought the app up to date, Semaphore has been working with our back-end team to develop and release new builds to our clients to improve the user experience and to add features to the application.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The re-write of the app libraries and UI was a complete success. All bugs were mitigated before release to the public. Client response the updated version of the app was very positive. Since the first release, there have been 2 newer releases, including some new features and performance and security improvements. These releases have been extremely positively received as well.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Semaphore has been very agile in its responses to our update requests, and bug submissions. They have even provided several solution suggestions to our back-end team when requested.
What was your primary form of communication with Semaphore Mobile?
Email or Messaging App
What did you find most impressive or unique about this company?
The greatest thing about working with Semaphore has been the very rapid delivery of feature requests, system improvements, and UI updates. The team at Semaphore has been very "on hand" to discuss changes as they evolve and have demonstrated that they are very enthusiastic about our product and services. Questions that come up are always answered very quickly and clearly. The team has consistently proven to be available and helpful.
Are there any areas for improvement or something Semaphore Mobile could have done differently?
If there are, I am not aware of them.
