You’ve probably never heard of Survey Sampling International LLC (SSI), but there’s a massive chance they’ve heard of you. Or, at the very least, they’ve had your phone number sitting in a database since the nineties. For decades, SSI was the invisible engine behind the world’s market research. If a politician wanted to know why they were losing the suburban vote, or if a cereal brand needed to know if people actually liked marshmallow stars, SSI provided the "who."
They were the kings of the sample.

Then everything changed. If you go looking for Survey Sampling International LLC today, you won’t find a shiny corporate headquarters with that name on the glass. Instead, you'll find a trail of mergers, rebranding, and a legacy that basically defined how modern data collection works.
The wild early days of dialing for data
SSI started in 1977. Think about that for a second. This was a world of landlines and physical mail. Tom Danbury and Beverly Weiman founded the company in Connecticut because they realized something fundamental: researchers had great questions, but they had no idea who to ask.
Before SSI, "random" was hard. You couldn't just click a button. You had to physically understand the geography of phone exchanges.
They pioneered what we call "Random Digit Dialing" (RDD). It sounds simple now, but back then, it was revolutionary. It allowed researchers to reach unlisted numbers, which meant the data was actually representative of the real world, not just the people who were fancy enough to be in the Yellow Pages. For a long time, if you were a researcher, you went to SSI. Period. They were the gold standard.
Why the name Survey Sampling International LLC disappeared
Businesses don't usually stay the same for forty years. They either die or they eat other companies. SSI chose to eat.
The biggest shift happened in 2017. That was the year Survey Sampling International LLC merged with Research Now. It was a massive deal in the "insights" world. At the time, they were two of the biggest players in the game. When the dust settled, they rebranded as Dynata.
Why the change? Honestly, "Survey Sampling International" sounded like a firm that lived in a basement with a bunch of filing cabinets. "Dynata" sounds like a tech company. It was a play for the future. They wanted to move away from just being the "phone call people" and become the "everything data people."
By the time the merger happened, SSI had already built a footprint in over 100 countries. They weren't just a local operation; they were a global infrastructure. They had panels—groups of millions of people who volunteered to take surveys—that were more valuable than the software used to track them.
The pivot from landlines to "Digital Panels"
The death of the landline almost killed the industry. Think about your own life. Do you answer the phone if you don't recognize the number? Probably not. I don't.

SSI saw the writing on the wall earlier than most. They shifted hard into digital panels. They started recruiting people through loyalty programs, airline miles, and gaming rewards. If you've ever taken a survey to get a few extra miles on your Delta account or a "free" gift card, you've likely interacted with the ghost of SSI.
But this created a new problem: Data Quality. When you call someone on a landline, you're pretty sure they are who they say they are. When you offer a $5 Starbucks card for a digital survey, you get "professional survey takers." These are people who lie about their age, their job, and their location just to finish the survey and get paid.
SSI—and later Dynata—had to get incredibly good at "digital fingerprinting." They developed tech to catch people using VPNs or those who were clicking through questions too fast. It became an arms race between the data collectors and the people trying to game the system.
The 2017 Philippine tragedy that nobody talks about
It’s not all spreadsheets and data points. There is a dark chapter in the history of Survey Sampling International LLC that many in the business world have forgotten. In December 2017, just as the merger with Research Now was finalizing, a horrific fire broke out at the NCCC Mall in Davao City, Philippines.
SSI had a massive call center on the top floor.
Thirty-seven SSI employees died in that fire. It was a devastating blow to the company and a grim reminder of the human cost behind global outsourcing. The company faced intense scrutiny over safety protocols and emergency exits. They ended up providing significant compensation to the families, but the event left a permanent mark on the organization's culture. It’s one of those things that doesn't show up in a marketing brochure, but it’s a crucial part of the company's history.
Is the data actually any good?
This is the big question. You’ll hear critics say that survey data is dying because of "non-response bias." Basically, only weird people answer surveys now.
If you're a normal, busy person, you ignore the emails. So, are the results skewed?
SSI’s whole value proposition was "Weighting." They used complex math to make sure that even if they only talked to three 20-year-olds and fifty 70-year-olds, the final report looked like the real population. It's $f(x)$ logic applied to human behavior.
Researchers like Pew and Gallup have used SSI samples for years. The math is solid, but the "human element" is getting harder to capture. As we move into 2026, the reliance on AI to simulate "synthetic audiences" is the new threat. Why pay SSI to find 1,000 moms in Ohio when you can ask a Large Language Model to act like 1,000 moms in Ohio?
The industry is at a crossroads. Dynata (the artist formerly known as SSI) is betting that "real human data" will always be more valuable than "AI-generated guesses."
How to handle your data if it's in their system
Look, if you’ve ever filled out a survey for a brand, your data is probably in the ecosystem that Survey Sampling International LLC built.
They are generally GDPR and CCPA compliant because they have to be. They aren't "data brokers" in the way those creepy people-search sites are; they are a research firm. They want your opinions, not necessarily your social security number.
If you want to opt-out, you don't look for SSI anymore. You go to the Dynata opt-out page. They have a centralized system where you can "unsubscribe" your phone number or email from their entire network. It actually works, mostly because they don't want to get sued by the FTC for TCPA (Telephone Consumer Protection Act) violations.
What you should do next
If you are a business owner or a curious consumer, the legacy of SSI matters because it dictates how companies talk to you.
- For Businesses: Don't just buy a "list." If you're looking for market research, understand the difference between a "convenience sample" (easy but biased) and a "probability sample" (the SSI gold standard).
- For Consumers: Be aware of "Sugging." That’s "Selling Under the Guise of Research." A real firm like SSI/Dynata will never try to sell you something at the end of a survey. If they do, it’s a scam, not research.
- Privacy Check: Periodically check your "advertising preferences" on big platforms. Much of the data SSI used to collect via phone is now being scraped from your digital behavior.
The era of Survey Sampling International LLC as a standalone name is over, but the way they taught the world to measure "the crowd" is still the foundation of every political poll and product launch you see today. They proved that if you ask the right people the right questions, you can basically predict the future.
Just make sure you’re asking real humans, not bots.
Next Steps for Your Data Privacy: To see if your information is still being used by the successors of SSI, visit the Dynata Trust Center. You can request a report of the data they hold on you or exercise your "Right to be Forgotten" under modern privacy laws. Most people find that once they opt-out here, the number of "random" research calls they receive drops significantly within 30 days.
