15 movers and shakers driving a new breed of startups in the enterprise tech IPO rush

Eliot Horowitz is one of the founders of MongoDB, along with Kevin P. Ryan and Dwight Merriman.

MongoDB, an open-source database company based in New York, went public in October 2017. MongoDB had raised $256 million before going public with a valuation of $1.6 billion. Since then, the company's market cap has swelled to $3.6 billion under Ittycheria. Today, MongoDB has over 30 million downloads and over 1,000 technology and service partners.

Starting in 2007, Horowitz wrote the core codebase for the popular open-source database today. Today, as CTO he oversees the engineering and product teams. Recently, he led MongoDB in introducing new licensing to prevent major cloud companies from selling its software without open-sourcing it.

Before MongoDB, Horowitz also co-founded an online retail search engine called ShopWiki, which he built and later sold in 2010. Horowitz had also worked as a software developer in DoubleClick.

In 2006, Horowitz was listed in BusinessWeek’s Top 25 Entrepreneurs Under Age 25, and in 2015, he was listed in Business Insider’s “Under 35 and Crushing It” list. Just last year, he was also named to Crain's NY Business 40 Under 40 Class list.

Sameer Dholakia is accustomed to using both hands to accomplish a variety of jobs — and not just because he's ambidextrous.

The India-born executive has served in numerous roles in the tech industry, from sales to product management.

Since Dholakia took the helm as SendGrid’s CEO in 2014, the company's revenue has quadrupled, and he led the company to IPO on Nov. 15, 2017. Twilio announced it would acquire SendGrid in a $2 billion deal.

Dholakia, who has ten siblings and grew up in a two-room flat in India, has previously served as CEO at VMLogix, which was acquired by Citrix. And he worked in sales, business development and product management for Trilogy, where he helped the startup grow to a $300 million business.

And his ambidexterity has given him another special skill: he can write with his left hand and throw a fastball with his right.

Lynne Laube is one of the co-founders of Cardlytics, along with Scott Grimes and Hans Theisen. On Feb. 8, Laube took Cardlytics public, and since 2008, she has secured over $200 million in capital from investors. At the time, this Atlanta-based company had a valuation of $273 million.
