Doppel is an Official Social Engineering Defense Partner of the San Francisco 49ers: two Bay Area organizations built on the same defensive mentality.

Today, Doppel is proud to announce a multi-year partnership with the San Francisco 49ers.
This one is close to home. Literally.
Doppel was founded in the Bay Area. It's where we built our first product, hired our first engineers, and spent years learning what it actually takes to defend something worth protecting.
The 49ers have been doing that on this ground for eighty years. Partnering with them is so much bigger than just a brand decision for us. It's a homecoming.
But the fit goes beyond geography. The 49ers have always relied on a standard of disciplined, proactive play. It’s a tradition that runs from Ronnie Lott to Patrick Willis to Fred Warner, players known for reading a play before it fully develops and closing the gap before it matters.
That's the same mindset we try to build into our technology.
At Doppel, we protect organizations from social engineering: impersonation, spoofed domains, fake profiles, cloned apps. These attacks don't try to break through a company's defenses head-on. Nowadays, they're designed to slip past them by looking convincing enough that no one questions them until it's too late. Stopping that requires the same instincts good defense requires on the field: anticipate the threat, cover the gaps, and act before it lands.
That challenge has gotten harder. AI has made impersonation cheaper, faster, and more convincing to produce. That includes everything from deepfakes aimed at executives to fake profiles built to erode a brand's trust with its own customers. Defending against it takes technology that can dismantle malicious infrastructure and respond at machine speed, across the entire social engineering attack chain.
Our three solutions operate on one Superintelligence Layer, enabling threats detected in one channel to inform defenses across the organization:
The 49ers have defended the Bay on the field for eighty years. Doppel was built here to defend everyone else in it: the brands, identities, and people who call the Bay home. That includes the 49ers themselves.
The 49ers have seen our platform in action, and this partnership deepens that work to protect their brand, executives, and fans from multichannel social engineering campaigns. It's a tremendous responsibility we take seriously given what this team means to us and to this city.
Throughout the partnership, you'll see Doppel show up right where the 49ers do: gameday promotions, in-stadium signage, and content built around our shared "Defend the Bay" campaign.
For us as co-founders, there's an added layer here. We started this company in the Bay, and we've watched the 49ers set the bar for what disciplined, relentless defense looks like for as long as we can remember. Partnering with them now, as a company built on the same principle, feels like a natural extension.
We're proud to serve as the Official Social Engineering Defense Partner of the 49ers and to mark Doppel’s first partnership with an NFL franchise. As AI changes what threats look like, we want to prove that AI-native companies can be a source of stability and trust, not just speed.
After all, that’s the same standard the 49ers have held themselves to for eighty years.
We're glad to be on the same side of the ball.
