5&Vine is trusted by the world’s leading VCs as a Fractional CMO for their portfolio companies. We build strong value propositions and brands, Challenger Brand strategies that disrupt markets, and execute paid and organic social and search campaigns that put points on the board.

Our team has helped startups attain exits and scaleups drive user growth that’s generated over $1.4Bn in follow-on financing.

Startup Services

We’re the marketing resources you wish you had in-house, but don’t. Here are the services we offer startup teams.


By engaging as your Fractional CMO and leveraging 5&Vine’s Challenger Brand Playbook, we can assess the vulnerabilities of your industry’s incumbent, identify your unfair advantage, and push you to a win.


We work with Challenger Brands to establish a new normal that goes beyond being better for your customers to benefit the planet. By developing plans to address the unmet needs of your customers, we’ll craft narratives that resonate while taking on the incumbents in your industry.

Branding: Logo & Naming

We deftly craft names, logos, and holistic brand identities that resonate deeply with audiences and stand out. We ensure these are authentic, powerful, and differentiated.

Growth & Digital Acquisition

We establish the tracking and dashboard foundations that your startup will build on for years to come. We develop holistic growth strategies that deliver ROI via paid social, paid search, and owned channels that complement organic efforts.

Social Media, Content & Community

By nurturing conversations across social media, email, blogs, and advocacy programs, we drive meaningful engagement that goes beyond likes and shares to build community, drive loyalty, and enable authentic customer evangelism.

Team Building & Mentorship

Alongside our mentoring work with market leaders, helping them unlock the potential of them and their teams, we’ve worked with dozens of startups to build and grow their full-time marketing teams and fill critical gaps.


5&Vine enabled Greenlight to drive massive customer growth, help parents raise financially-smart kids and close a Series A led by Amazon.
