New group messaging startup Mobilize raises $6.5 million


The Israeli startup Mobilize, a community management platform that helps businesses organizing and communicating with large external groups,  has closed a $6.5 million Series A financing round and launched the self-service version of its product.

Mobilize developed all the tools a company need to manage and engage its network. Among the company’s customers are UBER, Intuit, Google Developer Relations, Thiel Fellowship and more.

The investment was led by Trinity Ventures with the participation of Floodgate Ventures, Hillsven Capital, Array Ventures, Upwest Labs in addition to SaaS angels such as Eoghan McCabe, CEO of, and Sanjay Subhedar.

Mobilize is designed to solve the huge challenges of organizing and communicating with large external groups, and is optimized to help companies manage and motivate external groups such as on-demand workers, developer groups, contractors, resellers, and influencers. In the past year, while still in stealth mode, Mobilize worked with leading brands such as Microsoft, Docker, Etsy, MakerFaire, the UN, MasterCard, Salesforce, and Prezi as design partners. These companies as well as just over 100 others have adopted Mobilize to allow over 5, 000 network managers to manage over a quarter of a million global partners.

Mobilize has now launched a self-service version of the platform to enable all organizations to benefit from the power of an optimized group management platform.


Founded in 2014 by CEO Sharon Savariego and CTO Arthur Vainer, Mobilize has offices in Tel Aviv and San Francisco.

Savariego, who previously worked as a business development manager at uTest, has enlisted help from serial entrepreneur and tech executive Laura Yecies to help her with her new business.

“I have always been excited by the power and impact of new communication tools, ” said Yecies in a statement.  “The time is perfect for a new category of Network Relationship Management products that we estimate to be over $65 billion in value.”

Savariego said, “In the new economy, companies and organizations increasingly rely on large numbers of people outside their organization to achieve their missions. Groups have become business-critical and there is a growing need for group communication within every business, ” said Sharon Savariego.

“There are over a billion groups active today. Group communications solutions such as Google, Yahoo and Facebook have not evolved to meet their needs for situations where the communications are mission critical and not just casual chatter, ” said Ajay Chopra, general partner at Trinity Ventures in a statement.  “Think of this as ‘Slack for external communications’ to actually get stuff done.”
