The result is industry-leading coverage and data quality, helping sales and GTM teams connect with the right people faster.

What started as a better way to find emails and phone numbers has grown into a broader vision: becoming the trusted GTM data infrastructure layer powering modern revenue teams and AI agents. Today, more than 6,000 customers, including companies like AWS, Deel, HubSpot, Clay, Intercom, Unify,and Artisan, trust us to power their prospecting and enrichment.

The Role:

You'll be joining as our Head of Growth Marketing, reporting directly to our CMO.

FullEnrich is growing rapidly, driven by a strong product-led growth motion and a successful creator program. As we enter our next stage of growth, we're looking for someone to build and own our growth marketing function, scaling the channels that already work while identifying new opportunities to reach and convert high-value customers.

Working with a dedicated budget and qualified signup targets, you'll be responsible for building the forecasts, experiments, and processes needed to drive efficient, sustainable growth.

This is a hands-on, entrepreneurial role where you'll initially be both the strategist and the executor. You'll manage external agencies and contractors, run experiments, optimize performance, and build the foundations of a scalable growth function. As the business grows, you'll have the opportunity to shape the team, tools, and processes needed to support the next phase.

You'll work closely with our CMO, Product, Creator, and wider GTM teams, with significant autonomy to test new ideas, challenge existing approaches, and make a measurable impact on FullEnrich's growth.
