How we do it

We build custom software applications using today’s most advanced technology. But so do a lot of software engineering firms. So what makes us different?

Founded in 2011, Spark DGS is a design agency based in Doylestown, PA. S&F handles roughly 85% of Spark’s total development work.

This is what people think

Speed & Function has been an invaluable collaborator in expediting progress on the Wikimedia Foundation’s yearly engineering roadmap and key development projects. Whether it’s augmenting day to day maintenance of our platform codebase to more complex, strategic projects and experiments - we know we can trust Speed & Function to do the job well (and often ahead of schedule)
Mat Nadrofsky, Wikimedia Foundation
Director of Engineering
The S&F team has taken the time to develop a deep understanding of our program and how it works. They were very quick to pick up our Meteor.js code base and contribute to it productively. They are helping us develop a better workflow and to shape our long term vision for this project. The team has a fast response time and good communication skills.
MJ Klenk, RestoreCore
The Developmental Sprint® app, designed by myself and our Chief Business Officer and moved online by Speed & Function, enables individuals and teams to surface and overcome hurdles to success. Within three months of our initial conversation, we had our first beta-version to test with a client. Within six months, we were using it as a cornerstone of our business expansion. Our mission has always been to help people and organizations to get better at getting better. This app has enabled us to scale that mission within an organization by providing a common platform and language for identifying and acting on areas of improvement.
Andy Fleming, The Developmental Edge
Chief Executive Officer
The Developmental Sprint(R) app was my first time creating an online app. I needed a team with patience, compassion, and enthusiasm in order to help me execute against the plan. Speed & Function helped me to not only create the app, but to think through and practice how it would work. As a result, we now have an online app that supports our ever-expanding global business.
Claire Lee, The Developmental Edge
Chief Business Officer
I've been working with Nick and his team for about a year now. The quality of their work is by far the best I've ever seen. Even better, they are willing to spend extra time explaining what they are doing and to help you in any way possible.
Seth Goldstein
By far the best development company I've ever worked with — and I've worked with dozens. They are hands-on, precise, patient, highly-skilled, and actually care about what they are building. It's not a contract for them, they join in as if they are official members of your team.
Jason Sherman
The professionalism, care, and attention of the S&F team is fantastic. They take the time to truly understand their clients’ needs, they ask a lot of questions so that nothing is overlooked, and they deliver quickly and efficiently. We have finally found our forever dev team.
Sara Elliott, Encore Editions
Before our partnership with Speed & Function, we had two major outsourcing challenges: 1) poor project management/client services, and 2) lack of quality execution. Freelancers and companies alike produced amateurish deliverables that weren’t complete, the work purely transactional vs. part of our overall strategy. With S&F, we were relieved to see work that was completed end-to-end. We never have to pull teeth to get things finished. Their process demonstrates confidence in their expertise, and it’s helpful that the founder is here and available in Philly.
Before finding S&F, we had a handful of web developers that were unresponsive, slow to finish, and often didn't understand what we were trying to fix. In a very quick and responsive turnaround, S&F fixed one of our forms and implemented a few custom modules. They also supported us with some Drupal updates. Our website is now more manageable and secure.
22q Family Foundation
S&F has been instrumental in our project work, especially during ongoing month-over-month engagements. We look at them as an extension of our team. They have a deep pool of solid engineering talent. We never have concerns about the quality of their work or their ability to figure stuff out — that’s their greatest strength.
S&F is a solid business partner. Nick and his team are willing to do whatever it takes to make a project successful and to keep the customer satisfied. They are professional and thorough.
