Overall, community interaction is the cornerstone of successful start-ups and small tech companies. Many of these companies are using Open Source Software and/or are part of larger community with a specific focus (e.g. Big Data, Developer Tools, Cloud Tech, etc.).
Many of these companies could greatly benefit from dedicated Developer Relations team. If they could take advantage of the expertise available from such a dedicated individual or team, they could transition into greater community visibility thereby increasing sales and opening the hiring pipeline all while keeping up to date on the communities and technologies they focus on.
For companies unable or not ready to create their own team, they can leverage DevRelate for these needs. Leaning on the experience of over 100 speaking engagements at conferences and meetups, dozens of events and sidecar events organized, and various content delivery abilities (interviews, podcasts, blogposts), you gain the power of a full team without the overhead.
