The starting point · Where we came in

To the NFL, the fans are the business. All their products need to connect those fans to the league.

The NFL runs a whole ecosystem of integrated products, each with its own audience and its own game-day pressure. Fantasy Football creates a game and community beyond the stadium. Live video and film study bring the action to life. In-depth, live player statistics serve the most serious fans and broadcasters.

Slytrunk became a partner across that stack. On some products, we own everything end to end. On other products, we joined NFL employees in keeping the products at the top of their game. Fans expect all of the NFL's digital products to engage them with the same intensity the players bring to every Sunday. Slytrunk was trusted with that responsibility because we were always more than a vendor.

More than closing tickets

Slytrunk doesn't just complete what is in the statement of work. We care about the products we work on and the fans that are using them. Sometimes that means putting in the extra effort to do it right.

The NFL could easily see how our effort benefited their products and goals. The NFL's trust in Slytrunk meant they were always eager to hand us the next thing. A stack this big needs a partner who can focus on delivering for the fan and also slot into someone else's team without friction.

So we did both. From running Fantasy top to bottom to embedding with NextGen Stats, we are one team the NFL can point to for almost anything.

The idea we brought

Own what needs owning. Embed where it helps. Be one team either way.

Across five products we flex the engagement to fit the work: full build-and-run where the NFL needs an owner, a seat on the core team where they need hands, an embedded resource where they need depth. Slytrunk's experience at all levels means we are always able to contribute to the product's core goals.

NFL Mobile

What we built

Five products across the NFL.

01 · Fantasy Football

Built and run the entire fantasy platform

It was all ours to run, end to end. We built all the system interactions — the React Native apps, the fan website, the admin tools. We also built the entire backend: feed parsing, business logic, data, and the API platform. Slytrunk created, developed, and deployed Fantasy+ and Adaptive Draft Rank. We ran it all day to day and supported the NFL's marketing and customer-service teams.

02 · NFL Mobile

On the core team for the NFL+ app

We are part of the frontend / React Native team building the NFL's primary consumer app — team pages, the NFL+ Watch experience with RedZone and live games, and live scores and standings.

03 · Video Player

Live and on-demand video player

Nothing is more central to the NFL's business than watching the games. The NFL trusts Slytrunk with frontend video player development and operations for the NFL's streaming experience — NFL+, RedZone, and GameDay across phone, tablet, and the big screen.

04 · NFL Pro

Partnered with NFL Dev Team to build and run the web experience

Slytrunk partnered with the NFL to build NFL Pro. We built the web client, admin tools, and Film Room — the play-study tool that lets the most serious fans filter every play of the season and watch it from the sideline or the end zone. We run it day to day and support the NFL's teams around it.

05 · NextGen Stats

Embedded with the NextGen Stats development team

Our platform engineers huddle up with the NFL's NextGen Stats team. Together we build tools to analyze tracking data for fans and broadcasters. We even built an AI assistant — powered by AWS — that turns the tracking data into weekly insights fans read.

Our depth chart

Slytrunk quality teammates, at whatever position the product needs.

01 · Own it

Build and run it outright.

Fantasy was ours end to end — every client, the backend, the admin tools, and the day-to-day operation.

02 · Join the team

Take a seat on the core team.

On NFL Mobile and live video player, our engineers jumped in alongside the NFL's own. Together we ship the app and the streaming experience.

03 · Embed

Drop in where the depth is needed.

With NextGen Stats we helped fill the NFL's shortage of available platform engineers with our specialists. Our engineers were able to build the AWS-powered AI behind the weekly insights.

One partner, not five vendors

The NFL didn't have five vendors on their bench. It started one quality partner.

Each product started as its own engagement. What connects them is that Slytrunk kept earning the next product. Once the NFL saw how we could produce quality results and mesh with their teams, everyone wanted Slytrunk on their project. We didn't prove our value once. We kept doing it with each engagement.

That's the whole argument. One team the league can hand almost anything, and trust it to ship.
