Hopin's take on their challenges in 2021

Johnny Boufarhat headshot
Johnny Boufarhat
Founder and CEO

To meet the significant demand for our platform, we’ve had to ramp up hiring significantly - Hopin has grown from eight employees to over 200 across 38 countries in the same time. Hopin has over 60,000 event organizers including The Atlantic, Miro, Disney, NATO, TNW, Wildlife Conservation, TechCrunch, Twitch, UCLA, and The University of Notre Dame.

Because of the pandemic, there’s been a significant increase in demand for Hopin. Our recent $125 million Series B round will be used to help scale our platform and team to support the exponential amount of business we’ve seen over the past six months, to ensure we can meet the needs of our current — and future — customers.

At Hopin, our mission is to empower people to gather together in a way that is sustainable and accessible to everyone. Our platform is made to give our customers the freedom to create a fully customized event experience and empower event attendees to explore events the way they would in-person, while in a virtual environment.

Ultimately, we want Hopin to make the world smaller — by connecting people in meaningful ways so that geography no longer becomes a barrier to memorable live events and experiences. Virtual events have proved to be a cost-effective means to bring communities and attendees together. And as companies seek to expand their presence to meet demand due to stay-at-home measures, there will be significant growth opportunities for organizers and those in the event space. This opportunity will continue to grow after the pandemic, as businesses recognize the value of reaching larger audiences for their events through a hybrid approach — organizing events simultaneously online and in the real world.

Our take on Hopin

Kirsty headshot
Kirsty
Company Specialist

Hopin launched in 2019, and has been one of the fastest growth companies able to take advantage of the global shift to online meetings and conferencing that has taken place during pandemic lockdowns. They're now a fully fledged event platform, allowing companies to create immersive virtual, hybrid, and in-person event experiences for their audiences, no matter where they are.

Hopin has made several significant acquisitions in 2021 to further its capabilities and hit unicorn status. These have included Boomset, adding onsite capabilities such as kiosks and badges to its offering, and Attendify, enhancing its event marketing suite to provide elevated, data-driven registration and engagement tools.

They have been one of the fastest growing companies in the world over the last couple of years, and now has hundreds of thousands of customers, including the likes of Slack, Twitch, WSJ and UPS.

The panel's take on Hopin

Holly Bennett headshot
Holly Bennett
Head of Ecosystem & Portfolio Development at Accel

Hopin has become one of the fastest-growing European startups ever, having grown from a team of 4 to over 200 employees and a £2billion+ valuation only nine months after launch. Its virtual events technology caught a tailwind when COVID-19 cancelled travel and in-person events all around the world.

After growing annual recurring revenue from $0 to $20 million in nine months and having reached more than 3.5million users, Hopin's Founder Johnny Boufarhat intends to continue to hire rapidly into 2021, allowing the business to double-down on investing in its product. In November of this year, off the back of this incredible growth, Hopin announced a $125m Series B led by IVP and Tiger Global, along with participation from earlier investors such as Accel and Seedcamp.
