WHERE YOU ARE TODAY
Your data exists. It's just not activating.
Customers churn at Day 3. Repeat-purchase windows close before the next campaign goes out. SMS is “on the roadmap.” In-app was a 2023 New Year's resolution. Reporting comes back as vibes when what you need is repeat rate, LTV, and which campaigns paid for themselves.

FREQUENTLY ASKED QUESTIONS
Things founders ask before booking.
How fast can you actually launch?
Day 1 is the audit kickoff. By Day 14 we ship the first live flow into production, onboarding, cart abandonment, or whichever revenue gap is highest priority from the audit. By Day 30 the full lifecycle program is running. We do this consistently. We don't assign engagement managers and disappear for weeks.
What platforms do you specialize in?
Customer.io (we're the No.1 partner globally), Klaviyo (Master Silver), Braze (Alloys partner), Iterable, MoEngage, and CleverTap. We're platform-fluent, not platform-locked. We'll work in whatever stack you already use, and won't push a migration unless your tooling is genuinely broken.
What does the 90-day guarantee actually cover?
If we don't hit ~21% monthly active lift, ~15% daily active lift, and ~32% repeat-revenue lift within 90 days of going live, you get your full retainer back. Calculated against your own baseline data, audited together at the start. It's contractual, not marketing language.
Do you replace our team or augment it?
Both, depending on what you need. Some clients have a Head of Lifecycle and want senior bandwidth on top. Some have no one and want us to run the function end-to-end. We're senior strategists, no junior account managers, no offshore execution layer. The same people who run your audit run your campaigns.
What does ‘AI-augmented’ mean in your lifecycle strategy?
How does pricing work?
Who's actually on the team?
Senior strategists, certified across Customer.io, Klaviyo, and Braze. A dedicated lifecycle designer (the friction in Klaviyo isn't the platform, it's the design queue). An engineering bridge for event taxonomy and warehouse work. Founder-led on strategy. No part of this is outsourced.
