Lucas Chevillard
I'm Lucas Chevillard. I help organizations with €50M+ revenue uncover what's working, what's not, and where the biggest opportunities are in their CRM. I've spent 12 years in email marketing and CRM, including 5 years at Airbnb where I worked on email and lifecycle marketing at a massive scale across multiple markets. Now, I work independently with organizations across EU and US markets that need strategic clarity on their CRM operations. 20+ clients across e-commerce, marketplace, and service companies. I specialize in turning Customer.io from a messaging tool into your revenue engine. I build lifecycle marketing systems that connect directly to business outcomes through strategic implementation, revenue-linked measurement, and operational excellence. Why work with me on Customer.io? Your team likely faces these challenges: * Customer.io is configured but campaigns don't tie to revenue * Segments exist but personalization isn't moving metrics * Leadership asks "what's the ROI?" and you struggle to answer * Marketing ops caught between campaign execution and strategic influence * Data flows into Customer.io but insights don't flow out I turn Customer.io implementations into revenue-generating systems that your leadership can measure and trust. How I work with Customer.io: From strategic audits to hands-on implementation: Customer.io configuration & optimization, event tracking architecture, data integration strategy, revenue-focused campaign design, behavioral journey automation, A/B testing frameworks, cross-channel orchestration, attribution modeling, and performance reporting that connects to business outcomes.

Repetitos
If an executive asks “how healthy is our customer contact database," can you provide more than a vague “it’s pretty good” response? As Forrester's Director of Customer Marketing, I learned: 1. A customer contact database decays 2% monthly and bad customer contact data impacts from 3-5% of annual contract value 2. Bad data is the second biggest challenge when running customer campaigns 3. The third largest buying signal is being a past customer and 20% of new business revenue can come from repeat buyers Repetitos can update and enrich your customer contact database for pennies per name. With a clean database, you are ready for, and we can design a Repeat Sales by Former Customer Contact program.

E-commerce is growing fast, yet 94% of transactions still happen in the real world.
