Kayvon Beykpour

CEO & Co-founder at Periscope

Kayvon Beykpour

In era of app fatigue, the breakout success of Periscope, a livestreaming video app launched in March, is rare. Within a week, the app captured a million registered users; in four months, it hit 10 million.


Beykpour, who previously led mobile for ed-tech firm Blackboard, says Periscope is popular because it teleports viewers into the raw, unfiltered action, be it the immediate aftermath of the April earthquake in Nepal, a backstage view of a Taylor Swift concert, or musings of a bored teenager. It didn’t hurt public intrigue that Twitter acquired Periscope for a rumored $100 million before it even launched.


Beykpour, who manages his team of 24 in a separate San Francisco office away from Twitter’s headquarters, says Periscope’s mission hasn’t changed since the deal: “In its most successful carnation, [Periscope] builds empathy and truth.” – by Fortune.com

Tom Górski

Co-Founder & CEO of SaaSGenius

Tom Górski

I am an Entrepreneur, SaaS Growth Expert, and Inbound Marketing Consultant.


I have been named one of top marketing influencers on the Polish web by Whitepress, and called one of the best growth hackers by Medium. To date, my biggest accomplishment is achieving 4500% growth for one of my clients over a three­year period.


My career spans over 12 years of developing and implementing online marketing, SEO and conversion optimization campaigns. To date, I have cooperated with over 150 businesses representing more than 30 industries, including IT, finances, health & fitness, education and construction. I have catered for the needs of businesses of various sizes, including startups, non-profits, and even Fortune 500 companies.


I design creative marketing campaigns aimed at elevating brand awareness, improving customer loyalty and customer retention. My key goal is to drive more traffic and generate more leads, while simultaneously reducing overhead and improving ROI. In 2012, I have generated more than $12 Million dollars for one of the biggest fitness companies through advanced SEO synergized with effective social media campaigns.


Given that some traditional SEO techniques are now becoming redundant, I believe a different approach must be considered. I believe Inbound Marketing is exactly what we need – as a form focused on synergy of many marketing activities, it is bound to bring about positive changes in marketing worldwide. It is therefore my aim to popularize it as widely as possible.

Chris Wanstrath

You may not have heard of GitHub, but you’ve likely used technology that was birthed, built, or tweaked on its network. The ultra-geeky tech platform is the world’s largest collection of public code and the de facto place where developers now collaborate.


Wanstrath describes it for a layperson as Facebook for tech projects. (“You log in, you’re connected to people, but instead of seeing photos of their baby, you see their code.”) Facebook itself has used GitHub. So have SAP, NASA and the White House. Wanstrath launched GitHub in 2008 with Tom Preston-Werner and P.J. Hyett, mostly as a way to see and tweak each other’s ongoing projects.


Now it has $350 million in funding, a $2 billion valuation, and 11 million active users. (It has also weathered a sexual harassment claim that led Preston-Werner to step down.) Wanstrath, who was the company’s initial CEO and returned to the role in January 2014, aims to “lower the barrier to entry” and make the site more accessible to those just learning how to code. After all, he says, the future of the world is software, and “that’s what GitHub is all about.” – By Fortune.com

Later, he was the CEO of Quantivo, one of the first large-scale cloud-based analytics platforms. So he understands what it takes to build an analytics solution that people love.


It gets even better. Brian recently was the CMO of a successful SaaS company. As a result, he fully understands the new demands on marketing to drive more revenue. He knows that buyers have taken control of the process and that you need to understand customers and be data driven to truly optimize marketing. If you don’t know your customers and understand their behavior, you can’t create the right messages that engage them and guide them to conversion.


He understands that insights are the key to optimize marketing. Analytics must show you how to improve, not force you to spend hours sifting through a confusing mix of data hoping to find something relevant. – by KISSMetrics blog

Co-Founder & CEO of Optimizely

Dan Siroker

I'm the co-founder & CEO of Optimizely. The original inspiration for Optimizely came from my experience as the director of analytics on the Obama 2008 campaign. Optimizely is the product I wish we had back then to make it easy for anyone to do A/B testing.


Four years later, not only did Obama 2012 and Mitt Romney use our product extensively in the last election cycle but so have over 7,000 other customers including Starbucks, CNN, and Crate&Barrel.
