Please describe your organization.

We are a marketing development firm running programs for clean energy companies.

What is your position?

I am the chief executive officer of the company.


What business challenge were you trying to address with PromptWorks?

Part of the work that we do involves identifying barriers to market penetration for clean energy products and services. One of those barriers was a glitch in the sales process. There isn't enough financial information given to building owners when they want to upgrade the energy efficiency of their buildings. With the help of PromptWorks, we developed a web-enabled platform with an intuitive user interface for the purpose of removing that barrier.


Please describe the scope of their involvement.

PromptWorks developed our solution with the use of Ruby on Rails, which was the technology they recommended. Greg Sterndale [cofounder at PromptWorks] was our primary point of contact during the process. He brought in the different resources needed for our project and kept things running in order. We used Google Docs during the collaboration to manage and track certain tasks and deliverables.

How did you come to work with PromptWorks?

They used to be located in our building, so we were already familiar with them. We did originally consider other companies, but I liked the approach and thoughtfulness demonstrated by PromptWorks. They have a great talent pool there with very reliable and responsive management.

Could you provide a sense of the size of this initiative in financial terms?

The total development cost so far has been $72,000.

What is the status of this engagement?

They've been working on upgrading our platform and creating subsequent versions of it during the past two years.


Could you share any statistics or metrics from this engagement?

We've not kept track of quantitative metrics. Our solution was developed from scratch, and we are still making an effort to get it out into the market and obtain large-scale customers.

PromptWorks definitely helped us in terms of bug reduction. They came up with great methods of qualification on the back-end of the model. It's a financial model for which they employed statistical resources from Harvard for regression analysis. They came up with many expert insights for us during the actual development phase. The output error was reduced, from the method we were previously using, by 50 percent.

People have thought that our solution is a breakthrough tool in the industry. They're excited to use it, and we've had a small group of testers already. Overall, the reaction has been extremely positive.

How did PromptWorks perform from a project management standpoint?

Very well. We haven't had major issues on that front. They have an excellent team that understands the importance of transparency and consistent communication.

What distinguishes PromptWorks from other providers?

I have not worked with other providers for software development in the past. I evaluated other companies and saw that many vendors are run out of India. This would not have gotten us the level of customer service provided by PromptWorks. They're tuned into the project and act as part of our team. They help us achieve every goal that we set. I don't simply feel like they're an outsourced software developer for our company. They serve actively as another member of our team. PromptWorks is in it for the long run and they want the end product to be successful.

Is there anything PromptWorks could have improved or done differently?

They're almost always available when we call, so communication and responsiveness were never an issue. In the beginning, PromptWorks provided a very good interactive designer for us. That person developed the graphical user interface for the tool, which turned out fantastic. Unfortunately, this person is no longer with us. PromptWorks has other designers in-house, but they should make an effort to attract other resources of that caliber to their company.
