Growthly
Growthly helps ambitious B2B and B2C companies build lifecycle marketing systems that increase activation, engagement, retention, and lifetime value. We work with SaaS companies, marketplaces, mobile apps, ecommerce brands, fintechs, and other digital products to design customer experiences powered by Customer.io. Whether you're implementing Customer.io for the first time, migrating from another platform, or optimizing an existing workspace, we help transform customer data into personalized, event-driven journeys that drive measurable business growth. Our services include: * Customer.io implementation and onboarding * Customer journey strategy and mapping * Customer data architecture and event planning * Behavioral segmentation and personalization * Lifecycle marketing strategy * Email, SMS, push notification, and in-app messaging * Onboarding and activation journeys * Product adoption campaigns * Retention and engagement programs * Win-back and reactivation campaigns * Transactional messaging * A/B testing and experimentation * Deliverability optimization * Analytics, attribution, and lifecycle reporting * API integrations and workflow automation * Ongoing optimization and growth consulting What makes Growthly different is our ability to work across both B2B and B2C customer journeys. For B2B companies, we help turn prospects into customers and customers into long-term advocates through better nurturing, onboarding, product adoption, retention, and expansion journeys. For B2C products, including marketplaces, mobile apps, ecommerce businesses, and digital platforms, we build lifecycle programs that improve activation, repeat usage, retention, referrals, and customer lifetime value. For marketplaces and platforms with both business and consumer audiences, we help strengthen both sides of the ecosystem. That can mean onboarding and activating supply-side partners, increasing demand-side engagement, improving repeat usage, and creating coordinated journeys that support marketplace growth as a whole. We combine lifecycle strategy with hands-on implementation, so Customer.io becomes part of a connected customer engagement system rather than another standalone tool. Our focus is always on delivering the right message, to the right audience, at the right moment, based on real customer behavior.

SaaS Playbook
I help product-led SaaS companies convert more trials, reduce churn, and grow MRR through behavioral lifecycle email systems built in Customer.io. Most SaaS companies lose 40-60% of signups after the first session. My Train Track Methodology fixes this by mapping state-to-state user transitions with precise time windows and behavioral triggers, replacing generic nurture sequences with systems that respond to what users actually do in your product. At LANDR, I built the lifecycle program that contributed to 4x revenue growth in two years, including an upsell sequence generating 42% of weekly subscription conversions. What I Build in Customer.io: Activation sequences that move users from signup to first value, conversion tracks that turn trials into paid subscriptions, retention programs that reduce churn before it happens, expansion campaigns that grow account value, and reactivation systems that recover dormant users. How I Work: Discovery ($8,000): Full audit of your current setup, journey mapping, competitive benchmark, deliverability review, and prioritized roadmap using Train Track Methodology. Implementation ($8,000/month, 3-month minimum): I build the actual campaigns in your Customer.io account. Month 1 covers audit and strategy. Months 2-3 build and launch your core behavioral tracks across activation, conversion, retention, and expansion. Ongoing Optimization: Structured A/B testing on each track with full execution and bi-weekly calls. I can write copy from scratch, review what your team writes, or collaborate with copywriters. Either way, you get real campaigns live in Customer.io, not recommendations in a deck. Who This Is For: Product-led SaaS companies with 1,000+ daily signups, clear product-market fit, and self-serve conversion models. Typically Series A/B, VC-backed, with decision makers who can move without committees. I work with a maximum of 2 clients at a time to maintain quality. You get me directly, not a junior team ramping up on your business. Author of The SaaS Email Marketing Playbook, used by thousands of SaaS teams. 13 years in SaaS as founder, head of growth, and consultant.

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.

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.
