Catching up with Boca-based ZeroBounce: growth, global expansion, and new products aplenty

By Riley Kaminer

You may not have heard of ZeroBounce. But it is likely one of the fastest-growing startups in our ecosystem, and a Boca Raton tech success story.

The startup is on a mission to help companies ensure that the emails they send arrive in their customers’ mailboxes.

The problem: around 15% of email lists contain inaccuracies – anything from typos to predatory spam traps. But these threaten companies’ ability to send their marketing emails, potentially blocking them from critical platforms like Mailchimp. ZeroBounce’s solution enables companies to validate email addresses before they are used.

Founder and CEO Liviu Tanase told Refresh Miami that the company has experienced a year-over-year revenue growth of 53%. Meanwhile, their base of users has grown 60% annually and is now more than 200,000 strong.

 ZeroBounce’s team has expanded just as quickly. The startup now has around 50 employees globally, six of whom are based in South Florida. ZeroBounce recently made a smattering of new senior hires, including CMO Anne Ghaltchi, CTO Paul Pintiliescu, and Head of Cybersecurity Vlad Cristescu. 

Tanase attributes this growth to the sustained – and increasing – need for services that validate email. He also argues that their high quality customer support has made the startup stand out from the crowd. “Many other companies have support that is extremely bad: with low quality replies that take a long time.” ZeroBounce, on the other hand, prides itself on responding to customer queries quickly and effectively.

The bootstrapped startup has now validated more than 13 billion emails, serving major clients including Amazon, Disney, Netflix, LinkedIn, and Sephora. Looking forward, Tanase said that he is excited to continue onboarding new enterprise customers. 

Constantly improving ZeroBounce’s product is also top of mind for Tanase. The 2.0 version of their platform, which is currently in public beta, will be fully launched in December. Tanase asserted that the new platform will work 80% more quickly than the previous version, on top of an improved customer interface. Other new features in the pipeline include domain protection, more security features, and an increased ability to automate various aspects of their service.

Security has been a key focus for ZeroBounce of late, adding two more security certifications to the platform: SOC 2 Type 2 and ISO/IEC 27001:2013. “We really wanted to make sure that all of our customer data is super secure. We have really big brands that use us so we’re really keen on protecting their data.”

Florida still plays a major role in ZeroBounce’s growth trajectory. “The work ethic in Florida is so good,” noted Tanase, who is now spending more time in California. 

As for founders trying to replicate ZeroBounce’s success, Tanase asserts that the best thing to do is fail fast and pivot as necessary. 

“Sometimes you have a lot of good ideas, but the public might not actually need or want them. The idea is not to over-invest or create the perfect solution from the beginning. Release something to the public, and then spend money to make it work. But it is best to fail as soon as possible so that you can create something that consumers actually want.”
