Privacy Preserving Cryptocurrency Startup Iron Fish Run by Founder and CEO Elena Nadolinski Raises $27 Million

Cryptocurrency startup Iron Fish run by Founder & CEO Elena Nadolinski has raised $27 Million in Series A funding. Nadolinski is one of the leading privacy blockchain innovators focused on preserving privacy of digital transactions especially with cryptocurrency.

Elena Nadolinski grew up in Volgograd, Russia, playing on abandoned tanks and decommissioned battleships. While visiting Russia from Silicon Valley a few days ago, she says that she was struck by how Russia’s authoritarian surveillance continues to undermine the very nature of innovation.

“Lack of privacy, and having this expectation that I am surveilled, and I need to hide what I have, because I don’t actually have privacy guarantees,” says Nadolinski, speaking from her offices in San Francisco. “Has evolved the culture in a way that I think negatively impacts innovation, and entrepreneurship in the country.”

To help combat this chilling effect, the 29-year-old founder of anonymous cryptocurrency startup Iron Fish raised $27.6 million in a Series A led by Addreessen Horowitz to help ensure the next generations of Russians, and citizens of the growing number of authoritarian states around the world, can continue to have a private life, even if all the world’s transactions move to a shared, distributed ledger.

She and a growing wave of other privacy innovators building with blockchain have much more at stake than just what happens in the once-niche world of cryptocurrencies. In fact, it could have ripple effects reaching into the very nature of money, and whether or not online payments of all sorts—crypto or fiat—retain any sense of offline privacy when paying for goods with cash.

“The reason why I’m working on Ironfish is because right now we’re headed in a direction where payments are totally transparent,” says Nadolinski. “If you are a surveillance-happy state, this is the future you want. And for us, it’s kind of a scary future.”

Having been born in Volgograd, Russia to software engineers, she remembers her grandmother pointing out the only two buildings in what was then called Stalingrad that survived the war. After studying in Russia for first and second grade, she moved to the United States and in 2014 received a degree in computer science from the Virginia Polytechnic Institute and State University. Parlaying a Microsoft internship into her first engineering job at the tech giant she went on to work on property rental site Airbnb’s autocomplete function for locations.

In 2017, the rising star developer was invited to a birthday party at Ethereum developer Juan Benet’s house in Palo Alto, California. Three years earlier, Benet founded Protocol Labs to build technology that could enable a new version of the internet without central servers, called Web 3, and Nadolinski was struck by the openness of the blockchain developers she met, including the developer of Web3 portal, MetaMask, Dan Finlay, who helped her debug a smart contract she was working on at 3 o’clock in the morning. “I was like, ‘this feels like a magical open community,” she says. “‘Where there’s so much potential, and there’s so much to build.’”

A year later, she began working on the original version of Iron Fish, a privacy-preserving cryptocurrency built on Sapling Protocol, developed by Zcash. With early funding from Benet, Forbes 30 Under 30 alums, Jill Carlson of Slow Ventures Linda Xie of Scalar Capital and others, the cryptocurrency evolved to include a system whereby almost any cryptocurrency can be deposited into a smart contract that “wraps” it in the same anonymity as Iron Fish itself. Think of it as the secure sockets layer (SSL) of the internet, except instead of vouchsafing for the security of a website, it helps protect the privacy of nearly any cryptocurrency.

Based in San Francisco, the Delaware C Corp currently employs nine people around the world, including six developers. In April 2021 the firm launched the early version of its open source code, letting anyone build on the network, which is currently validated by 1,800 node operators. Earlier this month, they opened pre-registrations for an incentivized test network that will reward the validators and other network participants with points that qualified users will eventually be able to redeem for Iron Fish’s native currency, iron.

With other investors in the Series A including Sequoia Capital, LinkedIn executive chairman Jeff Weiner, billionaire Met’s owner, Alan Howard, and others, the firm plans to spend the capital to nearly double its team size, establish a treasury for assigning grants to companies building on the platform and redeeming incentive points for iron, and pay legal fees to help assure that the process is as compliant as possible. What they’re not doing though, is adding anyone to the board, something Nadolinski says is increasingly par for the course with crypto startups relying on a governance model built into the very fabric of the code.

“If there’s an update miners like or don’t like, they will either run or not run the updated software,” says Nadolinski. “There is, as with any cryptocurrency project, governance by action.”

This is at least the sixth investment Anddreesen Horowitz has made in crypto privacy startups over the past four years. Most recently, the firm earlier this month led a Series A in Switzerland-based Nym, which uses cryptocurrency, including bitcoin, to reward users who run nodes similar to the Tor Network. Three-point one billion dollars has been invested in privacy startups, according to datasite Crunchbase, with more than three-quarters of it over the past four years.

According to Fortune Business insights, privacy protecting technology will grow into a $17.75 billion industry by 2028, and research site ResearchAndMarkets.com predicts a $107 billion VPN market by 2027.

Iron Fish may be able to provide anonymous transactions for more than just traditional cryptocurrencies. The biggest threat to financial privacy in the past few years has been the emergence of Central Bank Digital Currencies (CBDCs), where traditional issuers of government-backed currencies are seeking to take advantage of the speed and efficiency that their decentralized competitors have to offer.

While everyone—from the Bank of International Settlements to David Chaum, whose work on electronic money was cited by bitcoin creator Satoshi Nakamoto,—has cited concerns over what this new kind of currency might mean, the second largest economy in the world, China, is slowly rolling out its own digital currency, and dozens of similar projects are in the works.

Supporters of increased transparency say such hybrid cryptocurrencies could undermine terrorist funding and money launderers, while detractors worry about some of the same chilling effects on innovation experienced by Nadolinsky. “Right now,” she says, “whether or not you’re a believer, disbeliever regulator, builder, whoever, you are inadvertently helping shape that inevitable future of digital payments being cryptocurrency-based.”
