01CRM & Lifecycle

CRM implementation that turns retention into revenue.

Install Customer.io, Braze or Klaviyo with event-based journeys, identity hygiene and deliverability. Activation, habit and win-back get designed instead of left to newsletters.

For SaaS and fintech teams (and ecommerce when retention is the constraint) that already acquire users and need lifecycle systems that protect LTV.

02The problem

Most teams treat CRM like a newsletter tool.

Without structured lifecycle journeys, users drift after signup. Churn rises quietly before day 90, and marketing burns budget re-acquiring people who never activated. Lifecycle marketing is revenue infrastructure: it decides whether a new user activates in the first 7 days, builds a habit by day 30, or churns before day 90.

03Lifecycle system

What a complete lifecycle stack covers.

Onboarding through win-back should share one event model and one measurement cadence. In practice that means stage-level metrics, frequency caps and experiments that compound instead of resetting every quarter.

01

Onboarding & activation

Clear path to value with behavioral nudges instead of generic drips.

02

Habit & retention

Usage-based triggers and early churn signals with automated interventions.

03

Win-back & offers

Segmented reactivation timed to predicted value rather than blast discounts.

04

Measurement cadence

Cohort tracking and stage-level metrics your team can run weekly.

04Customer.io

05How to implement

How to implement CRM in four steps.

A typical install takes 4–6 weeks: discovery and data audit in week 1, journey design in week 2, build and integrations in weeks 3–4, then optimization tests on subject lines and timing once flows are live.

  1. Step 01DiscoveryWeek 1

    Audit CRM, data and messaging

    Map current tools, event quality and consent. Note where journeys already exist versus where users drop.

    • +CRM and ESP audit
    • +Identity and consent review
    • +Priority journey backlog
  2. Step 02DesignWeek 2

    Map lifecycle journeys

    Design stage transitions for activation, habit, churn and win-back tied to personas and real product events.

    • +Stage definitions
    • +Trigger map
    • +Message frameworks
  3. Step 03BuildWeeks 3–4

    Implement flows and integrations

    Build in Customer.io, Braze, or Klaviyo; wire analytics and warehouse events; QA deliverability.

    • +Live flows in your account
    • +Data integrations
    • +QA + documentation
  4. Step 04OptimizeOngoing

    Test and transfer ownership

    Run controlled tests on timing and creative. Train your team and hand over a weekly review cadence.

    • +A/B tests
    • +Team training
    • +Weekly KPI review

Why this instead of another newsletter vendor.

Agencies often ship campaigns. In-house teams often inherit messy events. This engagement installs taxonomy, identity, deliverability and stage journeys your team can own.

08FAQ

Questions founders ask.

/01Which CRM platforms do you work with?+
Customer.io, Braze, and Klaviyo are the primary stack. I also advise when another tool fits better for your data model and team.
/02How is Customer.io work different?+
I’m a Customer.io Certified Partner. That covers implementation and migration, event and attribute architecture, deliverability, lifecycle automation, QA and team handover. Campaign copy is only one piece.
/03How long does implementation take?+
Typically 4–6 weeks for a focused install, longer when data integrations or multi-market consent rules are complex.
/04Do you create content for flows?+
Yes. I provide templates and testing frameworks, and collaborate with your content team for brand alignment.
/05What if our customer data is messy?+
Cleaning and structuring data is part of the work: identity rules, merge hygiene, and a plan to improve quality over time.
/06Can CRM integrate with analytics and product?+
Yes. Integrations with analytics and warehouses keep triggers accurate and reporting decision-grade.
