Growth Marketing Lead
About Ambrook
Ambrook's mission is to make sustainability profitable for family-run businesses.
In the face of historic heat waves, drought, flooding, supply chain disruptions, water shortages, and pollution, climate impacts are intensifying across industrial America: from farmers facing crop losses, to truckers navigating fuel volatility, to contractors managing material shortages. Evidence shows sustainable practice upgrades deliver financial returns – from water-efficient irrigation to fuel-efficient fleets – but these changes require significant upfront capital and a clear proof of return-on-investment to owner-operators facing tight cashflows and razor-thin margins already. With data scattered across paper records and outdated systems, operators struggle to forecast whether a practice change will improve their bottom line – let alone prove business health to lenders and other funders.
Ambrook is solving this chicken-and-egg problem by re-architecting the financial data layer of America's independent businesses. We're replacing unruly paperwork and expensive, archaic tools with an affordable accounting, banking and payments platform that helps operators understand their numbers and access capital for sustainable transitions.
Ambrook customers are our economy’s historic backbone and a manifestation of the American Dream. Done right, both financial and environmental sustainability enables these entities to stay independent and resilient in the face of climate-driven volatility.
We’re starting by building for farmers and ranchers across America.
We’re a Series A startup backed by top investors (Thrive Capital, Dylan Field, Homebrew, Designer Fund, BoxGroup, and more) and are looking for early team members who are looking to untangle the knotted intersection between American industry and climate.

The Opportunity
Ambrook has grown 10x in the last six months thanks to the might of generalists. Now, we’re looking to go even faster—with a specialist who can turn paid and organic traffic into pipeline.
We’re hiring a Growth Marketing Lead with a deep expertise in conversion rate optimization (CRO)—someone who especially thrives after the click. You’ll manage paid media agencies and budgets, yes—but your ownership really shines in the entire post-click experience, from landing pages to lead flows to attribution frameworks and checkout optimization.
You’ll report to our Head of Growth and will work closely with sales and product teams.
What You'll Own
Performance marketing: Own and scale our paid acquisition efforts (Meta, Google, and others), managing a multi-million dollar annual budget with discipline and creativity.
Conversion infrastructure: Lead our experimentation roadmap across landing pages, lead capture, onboarding, and checkout flows.
Agency management: Be the strategic lead for our paid ad agencies—driving the high-level strategy while building the internal systems to convert traffic effectively.
Attribution & analytics: Partner with engineers to build out deeper attribution, tracking, and A/B testing frameworks.
Cross-functional CRO enablement: Work across teams to share best practices in CRO, ensuring copy, creative, and UX decisions align with conversion goals.
Within 1 Month, You'll...
Take ownership of our paid channels and optimize for more efficient acquisition.
Audit and improve our existing CRO stack—landing pages, lead forms, and content flows.
Establish working rhythms with designers, engineers, and our growth agencies.
Dive into our customer research and develop deep intuition about our audiences.
