Companies can’t avoid working with data, but management of that data can pose serious challenges.
Customer and other personal data keep escaping, courtesy of breaches that surged 78% last year in the U.S., hitting a record 3,205. Total victims? An eye-popping 353 million.
And don’t forget the trust issues created by using real-world data to train AI. That hasn’t worked out so well for accident-prone autonomous cars, or for reliably racist chatbots.
Part of the solution? Synthetic data.
To be clear, synthetic data isn’t fake. In fact, it can be better than the real thing. Let me explain, with help from executives at a pair of synthetic data providers.
Synthetic data falls into two buckets, says Yashar Behzadi, founder and CEO of San Francisco–based Synthesis AI.
Structured data is what you find in database tables from industries like banking and health care. Let’s say a hospital doesn’t want to expose any patient data. “What you can essentially do is create a copy of that data that has all the statistical properties, but none of the actual information or data,” Behzadi says. “That allows folks to then work on it or share it and take it outside of specific safety bounds.”
Then there’s unstructured data—images and video used by applications based on computer vision. That’s where Synthesis plays, using CGI and generative AI to create data that helps train the systems behind technologies such as identity verification, extended reality (XR), and driver monitoring.
For example, if a facial recognition model is trained without a balanced dataset, it might have biases against dark-skinned or older people. To avoid that, Synthesis builds digital humans and uses them to generate high-quality data. “We can easily represent every ethnicity, every age, every different demographic to ensure our systems are completely bias-free,” says Behzadi, whose customers include Fortune 500 companies. “If it’s synthetic, it’s completely privacy-compliant as well.”
Alexandra Ebert is chief trust officer of Vienna-headquartered MOSTLY AI, which provides AI-generated, structured synthetic data for banks, insurers, telecoms, and health care companies. “They have plenty of existing data, but of course, it’s privacy-sensitive,” says Ebert, who runs an online course on synthetic data. “What they want to use synthetic data for is to basically anonymize it so that they’re out of scope from privacy laws.”
One of MOSTLY’s clients, bank Erste Group, likes synthetic data because it’s considered superior to traditional anonymization methods, which offer ways to piece the original data back together.
Synthetic data is taking off. By this year, 60% of the data used to train Al models will be synthetic, Gartner has predicted. That’s a huge jump from just 1% in 2021.
With help from generative AI, it’s now possible to create sophisticated simulations using unstructured synthetic data, Behzadi notes. Because that data is easier and cheaper to generate than real data, some applications will explode, he reckons. Rather than spend billions deploying fleets, autonomous vehicle makers can build simulations that include so-called edge cases, like a child running in front of a car. Another use: creating digital doubles of robots.
Ebert highlights data augmentation—using a synthetic data generator to create information that wasn’t in the original data set. For instance, a bank could take that approach to better understand fraud cases.
She also sees a chance for companies to democratize data by launching internal synthetic data hubs. The goal: “to go from synthetic data as a resource that belongs to the high priests of data science within an organization to data that is used by everyone.”
That would be real progress.

Wedding alarm bells
For Kevin O’Leary, nothing says love like separate bank accounts. In a recent TV interview, the Shark Tank star said he “forbids” family members to blend finances with their partners and forces prenups on them. “You must, in this society, maintain your own financial identity,” warned venture capitalist O’Leary, who’s reportedly worth $400 million.
Wealth gap
Baby boomers have lost the trust of millennials and Gen Z, Larry Fink concludes in his annual letter to BlackRock shareholders. As Dylan Sloan writes, the CEO of the $10 trillion asset manager blames boomers for avoiding tough decisions about retirement reform. Left holding the bag: younger generations, for whom hope and financial security are in short supply.

Would you trust a “finfluencer”? The U.K.’s Financial Conduct Authority takes a dim view of people who flog financial advice online. In new guidance, the FCA promises stiff penalties for failing to include adequate risk warnings, Orianna Rosa Royle reports. Its numbers add up: Offenders could get two years in jail, an unlimited fine, or both.
Trade talks
Xi Jinping is seeking the confidence of corporate America. In another sign that relations between Beijing and Washington are thawing, the Chinese president just hosted a meeting with top U.S. business leaders where he called for closer trade ties. Despite that gesture, expect Xi and Joe Biden to keep playing the blame game over U.S. tariffs and China’s export surplus.
TRUST EXERCISE
“Glassdoor has evolved—but our commitment to user anonymity is steadfast, evidenced by more than 15 years of fighting for anonymous users to have their voices heard.
Having the power to be anonymous, but knowing that the people you are speaking with are verified, has enabled constructive conversations on a massive scale. Worklife is changing—and we’re focused on creating a home for real talk that enables anonymity and trust.”
Job review site Glassdoor made a name for itself by letting visitors post anonymously, without fear that their feedback would land them in trouble with an employer. But to sign up for Glassdoor Community, an offshoot that launched last summer, users must share their name, job title, and company name.
After the confusion that followed, CEO Christian Sutherland-Wong sought to clear the air by explaining what could be construed as an attempt to have it both ways. Glassdoor Community gives people a choice between posting anonymously or revealing their name, Sutherland-Wong says. As for confirming identities, it deters trolls, fraudsters, and other bad actors from misusing the platform, he argues. Fair enough, but it still clashes with the brand trust that Glassdoor built, one anonymous review at a time.
