Turn one-time buyers into lifelong customers, with lifecycle systems that compound revenue.
Acquisition is expensive. Retention is margin. We build lifecycle-driven retention engines that keep customers active after the first purchase: Klaviyo email flows, SMS & WhatsApp touchpoints, reviews and onsite personalization, orchestrated around customer intent, not random campaigns. The outcome: higher LTV, lower churn, stronger brand loyalty and predictable growth without buying more traffic.
Retention Marketing Agency
Retention is your second growth engine, if you run it like an operating system.
Most brands have a “newsletter problem”, not a retention strategy: inconsistent messaging, no segmentation, broken customer data and no feedback loop between product, reviews and lifecycle. We build a retention system that connects the full chain: Customer Data → Segmentation → Automated Journeys → Personalization → Reviews/UGC → Measurement. So you don’t just send messages, you move customers through lifecycle stages and compound profit.
We build a retention blueprint across RFM, cohorts, intent signals and lifecycle stages (new, active, slipping, churned, VIP). This becomes the system for all automations and campaigns — consistent, scalable, and measurable.
We design and implement high-impact flows: Welcome, Post-Purchase, Replenishment, Browse/Cart Abandonment, Winback, VIP and cross-sell sequences, built around timing + intent + offer logic, not templates.
We add SMS/ WhatsApp where it creates incremental revenue: time-sensitive nudges, back-in-stock, delivery moments, review requests, winback triggers, with frequency governance to protect brand equity.
Retention isn’t only messaging, it’s trust. We operationalize review generation, post-purchase feedback and UGC loops to reduce churn, improve conversion, and strengthen customer confidence.
We connect onsite behavior to lifecycle logic: personalized offers, dynamic messaging, intent-based prompts and friction insights to improve conversion and feed smarter segmentation.
We align reporting on what leadership actually cares about: LTV, repeat rate, churn risk, margin contribution, CAC payback support, cohort health — with a clean KPI setup that prevents vanity reporting.
Our Approach: The Lifecycle Growth System
We don’t “send campaigns.” We build retention as an end-to-end system: strategy, automation, creative execution and measurement — so results compound instead of resetting every month.
Results that show up in business
Qualified leads or increased organic revenue are core results next to visibility growth, reduced Customer Acquisitions Costs and AI citations.
Before we'll start a unique set of KPI's will be defined to deliver impact over vanity metrics, e.g. organic conversions for a climate tech company.

Building a B2C growth engine in a traditionally offline health system:
GAIA is a leading digital therapeutics company with over 20 years of experience and clinically proven products, but B2C was not an established acquisition channel. Sales historically relied on an offline process involving doctors and health insurers, with no existing digital funnel for direct patient acquisition.
The challenge was fundamental: how to translate a highly regulated, trust-based, offline healthcare journey into a compliant, scalable digital funnel for patients, while meeting the highest standards for data protection and medical sensitivity. Strategy existed, but no operational B2C engine was in place.
Designing and operationalizing a compliant B2C funnel from scratch:
We designed a full digital B2C funnel end-to-end, covering address capture, health insurance validation, doctor data handling, and compliant communication flows. From initial flowcharts to a first live version, the funnel was built within three weeks and fully stabilized within ten. In parallel, we implemented a complete full-funnel tracking and experimentation setup across GAIA’s core brands "deprexis" and "somnovia*" including server-side tracking, multivariate testing, and Looker dashboards for performance benchmarking. Paid Search (including PMax) was launched as the primary acquisition channel, supported by HubSpot workflows to re-engage users dropping out of the funnel. Foundations for organic growth were scoped in parallel, including CMS requirements and SEO readiness.
From zero B2C setup to a scalable acquisition system:
Within three months, GAIA launched a fully operational, trackable B2C lead acquisition pipeline. Paid Search became a scalable growth lever, with ad spend increasing by +540% for somnovia and +826.9% for deprexis, while lead acquisition scaled accordingly. Traffic grew by +376.4% for somnovia and +130.8% for deprexis, while acquisition costs moved onto a sustainable, scalable trajectory. B2C is now an incremental growth channel for GAIA, with the funnel being rolled out across additional markets and digital therapeutics brands.
Rebranding without a scalable growth engine:
MHC Mobility entered a major rebrand and redesign phase with a clear market positioning, strong personas, and a new visual identity.
However, the website ran on Salesforce and was not marketing-owned: every change required development resources, content updates were slow, and technical SEO issues repeatedly blocked scale. Strategy existed, execution didn’t.
Platform shift to unlock marketing speed:
We recommended a decisive move away from Salesforce to a marketing-controlled platform.
Together with MHC’s team and partner agencies, we migrated to a WordPress-based setup built for SEO, content scalability, and technical reliability. This unlocked rapid content rollout, proper site architecture, and the ability to systematically build organic demand.
Following the platform migration, organic performance accelerated significantly. Clicks increased from by +63%, while impressions grew by +97% within six months. Organic traffic became the largest acquisition channel, driving 41.77% of total leads, with non-brand organic leads increasing by +964.86%. Visibility (Sistrix) grew by +1.180% covering essential non-brand keywords.
Entering a New Market with a Scalable SEO Engine.
Dalma expanded from France to Germany but lacked content, visibility, and proper tracking. The French SEO playbook couldn’t be reused, and no attribution framework existed to guide decisions.
We rebuilt their German SEO strategy from the ground up: transactional-first content, full tracking implementation, an AI-powered content pipeline, technical fixes, and GEO/AIO optimization for LLM visibility.
- German market activated from zero;
- 170+ content pieces;
- Break-even on organic leads after just 3 months (agency ROI fully covered by lead output);
- +272% organic click growth;
- +940% impression growth;
- Strong LLM presence in high-intent insurance queries;
- France restructured.
ROHDE is a heritage brand with more than 150 years of history, yet until 2021 it operated exclusively as a B2B business. Shifting to a D2C model required building a completely new online shop and establishing an entirely new digital operating model within just three months.
Boost It stepped in as ROHDE’s operational D2C unit, taking ownership of project management, tracking, SEA, CRM setup, content seeding, and business strategy - complementing the internal team and ensuring execution at speed and scale.
Since 2021, ROHDE has built a meaningful share of its revenue through D2C and established a completely new way of reaching customers.
- ~7× revenue growth within three years;
- ~122% YoY CAGR;
- Organic Search scaled to 6× its original level, becoming a top-3 revenue channel;
- Paid Search contributes 40–45% of revenue in peak seasons, guided by a ROAS of ~6;
- CRM became the most efficient channel, reactivating ~22% of customers at the lowest CPO in the mix;
- Server-side tracking implemented end-to-end, including attribution models across BigQuery, Stitchdata, and a Postgres database
McMakler was scaling a PropTech-brokerage model with a strong public valuation tool but its digital presence suffered from poor SEO structure, content cannibalization, and an unoptimized site architecture that risked undermining both visibility and crawl-efficiency across Germany’s extensive real-estate market.
We led a full SEO health audit, overhauled content architecture into strategic content clusters and magazine-style hubs, consolidated short-format pieces into authoritative long-form content, and developed internal linking logic to support "McCompass valuations", selectively focusing on high-value cities/areas to maximize crawl budget and ranking potential. All this positioned McMakler both as a data-driven PropTech brand and as a trusted information resource.
- Enabled McMakler to leverage its McCompass tool as a lead acquisition engine, fueled by SEO rather than purely paid or offline marketing;
- Created a scalable content backbone aligned with the brand’s hybrid digital + local identity, supporting trust, traffic growth, and long-term organic acquisition;
- Mitigated SEO risks (cannibalization, poor architecture) at a time when McMakler was investing heavily in growth and positioning itself as a market leader.

Questions other Clients asked.
Answered before you invest.
- Do you work only with Klaviyo?
We’re tool-agnostic, but Klaviyo is a no-brainer for many D2C brands especially if you run of Shopify. If you’re on another stack, we align on what’s best for your business model and data setup. With Hubspot, Pipedrive and Emarsys we already built great solutions. - How fast will we see impact?
Core flows can drive measurable uplift within 2–4 weeks. Full lifecycle maturity (segmentation + testing + review loops + personalization) compounds over 30–90 days. - Do you do only automations or also campaigns?
Both. Automations build the baseline engine. Campaigns and launches are the scale lever but only after the lifecycle foundation is stable. - Can you run Email + SMS + WhatsApp without spamming customers?
Yes, with frequency governance, intent-based triggers, suppression rules and cohort logic. Retention should increase loyalty, not burn it. - What do you measure for retention success?
LTV, repeat purchase rate, churn risk, cohort health, contribution margin and incremental impact of flows/ channels, not only opens and clicks.
