David McJannet Joins Greylock as EIR


I am thrilled to share the news that Dave McJannet has joined Greylock Partners as an Executive-in-Residence. When it comes to understanding the intersection of developer defined infrastructure and enterprise IT buyers, there is no better executive than Dave. He has worked in some of the most interesting enterprise software companies over the past 15 years including webMethods, Microsoft, VMware, Hortonworks, and Github. As a Greylock EIR, Dave will be a valuable asset to our portfolio companies by helping them with product and go-to-market strategy. He will also help source and vet new investment opportunities in partnership with our investment team. His background and integrity makes him a perfect fit for the Greylock family and we are excited that Dave is joining the team.

I was lucky enough to work with Dave more than five years ago when VMware acquired Springsource. Dave was the first person brought on post acquisition to lead product marketing at Springsource and he and his team reported into the Cloud Application Platform product team that I was running for VMware. The business unit included Spring, vFabric, and Cloud Foundry. In two years, I saw Dave strategically (and successfully) drive marketing and go-to-market strategy for key products such as the Spring Framework, vFabric, RabbitMQ, Cloud Foundry and the in-memory databases GemFire and SQLFire. During his tenure, Dave scaled revenue by 10X and transitioned the business into the company that is now known as Pivotal Software. After his tour of duty at VMware, Dave joined Hortonworks as an early employee when the company had minimal revenue. While there he built and led the overall marketing organization that enabled the company to scale through multiple phases and ultimately through its successful IPO.  Following the Hortonworks IPO, Dave briefly spent time as VP of Marketing for GitHub where he further developed his unique perspective on the transformations underway across the enterprise software ecosystem.

As Dave and I were talking about his next venture, we shared similar views with respect to patterns emerging in the enterprise space with a special interest in next generation applications leveraging the transitions at the infrastructure and data layers. Dave has always had this unique ability to bring fast growing companies to the next level (he helped his last two companies go from minimal revenue through $100M+ in revenue) and is ready to be part of the next big thing. 

With Dave on board, Greylock portfolio companies will reap the benefits of his knowledge and skills in product marketing, positioning, demand generation and the role of digital in building highly efficient enterprise go-to-market strategies. Given his track record, I’m confident that Dave is going to play a pivotal role and I can’t wait to see it all unfold.
