This is a list of startup and tech companies in the San Francisco Bay Area that use Marketo for their Digital Marketing and Marketing Automation efforts.
tl;dr -
Marketo is a public company, owned by Adobe that builds Marketing Automation software. Digital Marketers use Marketo to set up campaigns, email marketing, landing pages and all sorts of things. I have not used Marketo myself, but recruited for it heavily when I was an agency technical recruiter. Marketo can be a complex product with tons of functionality. The companies on this list below have or are hiring Marketo experts to grow their B2B or B2C digital marketing campaigns.
It's common to find Marketo integrated with Salesforce and used as a way of tracking Marketing Qualified Leads (MQLs) or Sales Qualified Leads (SQLs). Alternatives to Marketo include Eloqua by Oracle, Pardot by Salesforce or Hubspot for some of the same functionality.
