High-fidelity design prototypes.
Fully developed app with implemented features.
Integration with third-party and custom REST endpoints.

To take our input throughout the project and respond accordingly.
To deliver it to the Apple and Android marketplaces.

We were very pleased with the project management. They completed within a reasonable timeframe (there was some flex due to new feature requests) and delivered with room to spare for two critical milestones and a time-sensitive demo event. They also communicated well, coordinated all QA testing and releases, processed bug reports and feature requests well, and were a pleasure to work with overall.

They understood our vision, didn't push back against challenging requirements, and were always friendly and professional.
They modeled what a great end-to-end application development process should look like!

Are there any areas for improvement or something JSGuru could have done differently?

I don't have anything to recommend!

Project summary

JSGuru offered custom software development for a sales intelligence company. The vendor had been taken in for their adaptability and creativity.

Feedback summary

JSGuru implemented all the client's ideas into one intuitive interface. The vendor exhibited flexibility and knowledge about the internal team's industry, as well. They built a good relationship with timely deliveries.
BACKGROUND

Please describe your company and your position there.

I am the CEO of Cognism. Cognism is a B2B lead generation, outbound automation and data processing service. We maintain a database of 5.6 billion data points, including 400 million business profiles and 10 million companies. This unique data asset provides B2B organisations with a GDPR compliant way of prospecting leads and enriching data.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire JSGuru, and what were your goals?

We hired JSGuru for a number of custom software projects to experiment with new ideas or build new modules we did not have technology capacity for.

SOLUTION

How did you select this vendor and what were the deciding factors?

We worked with JSGuru on multiple projects in the past, and thus we have a strong connection with them. Obviously, we completed our work together successfully on those past occasions and kept coming back to them for new work. Their ability to adjust fast sets them apart, which is essential because we build marketing products that require a particular dynamic.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

We primarily worked with their UI/UX design team. We scoped out the project and used AngularJS for implementation.

How many people from the vendor's team worked with you, and what were their positions?

1 project manager, 1 UI/UX designer and 1 developer.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

After a couple of weeks spent in the ideation phase, JSGuru designers implemented all of our ideas into one intuitive interface that we will be able to test with our users very soon.

Describe their project management style, including communication tools and timeliness.

Used Zoom and Slack for communication. Everything was done efficiently and on time.

What did you find most impressive or unique about this company?

We're impressed by their flexibility and domain knowledge for our industry. Deadlines are always tricky for us and JSGuru has delivered on all occasions. The management also understands business in general and how to build a good relationship.

Are there any areas for improvement or something they could have done differently?

We have been familiar with one another for a long time and had a couple of projects to learn how both sides operate. So, we don't have anything special to add or ask for a different outcome.
