Most ecommerce and marketplace brands with real traction are leaving significant revenue in the gap between acquisition and repeat purchase. I build the AI-assisted lifecycle, CRM, and automation systems that close that gap and make revenue growth predictable. In my most recent role as Head of Community and Growth at a live commerce marketplace, I scaled daily GMV from under $10,000 to over $100,000. Buyer GMV retention went from 25% to over 80%. I managed $100,000+ per month in acquisition spend while simultaneously building the retention infrastructure that made that spend compound instead of leak. I have done lifecycle, CRM, community growth, paid acquisition, product-adjacent work, and operations at the same time inside a fast-moving platform environment. That breadth matters because revenue leaks are rarely isolated. They are usually a sequence of small failures across acquisition, onboarding, engagement, and retention that compound silently. What I build and run: Lifecycle and retention systems using Klaviyo, CustomerIO, and AI-assisted sequencing. Marketing automation workflows that reduce manual execution and founder dependency. CRM infrastructure, lead scoring, and follow-up systems tied to revenue. Onboarding, activation, and re-engagement flows for ecommerce, marketplace, and SaaS brands. AI workflow integration that connects strategy to execution without adding headcount. My process starts with a diagnostic: map the current funnel, find the highest-revenue leaks, and prioritize the first system that creates measurable impact. From there I build, document, and hand off systems your team can actually run without me. I work best with brands that already have traction and need the operating layer between their growth strategy and actual revenue recovery. If you are still validating your product, I am probably not the right fit yet. If the problem involves lifecycle, retention, CRM, automation, or AI-assisted marketing infrastructure, I can usually diagnose it quickly. I will tell you in the first conversation whether I can help and what I would look at first.
