The Subscription Growth Problem
Why subscription growth breaks
Subscription businesses face a unique growth paradox — the metrics that look good rarely predict the economics that matter.
LTV:CAC is contested
Marketing measures ROAS. Finance measures payback. Neither team is looking at the same number — so no one is making the right call.
Retention is optimised in silos
Lifecycle runs its sequences. Performance runs its acquisition. Neither function accounts for what the other is doing to unit economics.
Attribution breaks at scale
As channels stack up, incrementality becomes noise. You're flying the business on a dashboard that stopped being accurate quarters ago.
What We Fix
How the Growth Operating System runs inside subscription businesses
We don't advise. We embed, operate, and deliver — across the full subscription growth stack.
LTV:CAC Infrastructure
Violet connects your ad platforms, CRM, and subscription data into a single LTV:CAC signal. Marketing and finance finally look at the same number.
Trial & Onboarding
We redesign the trial-to-paid conversion path — testing onboarding sequences, paywall positioning, and offer structure against contribution margin.
Retention & Winback
CRM sequences aligned to churn prediction models. Winback programmes sized against LTV, not cost. Every touch accountable to net revenue retention.
Acquisition Efficiency
Paid social, search, and affiliate — reallocated weekly via the Capital Allocation Loop. Budget follows contribution margin signal, not ROAS.
Cohort Analysis
We build cohort models that show the true LTV trajectory of every acquisition vintage — so leadership can make capital allocation decisions on real data.
Pricing & Packaging Tests
We design and run pricing experiments aligned to LTV:CAC — finding the offer structure that maximises long-term margin.

What the system delivers for subscription businesses
How We Work
LTV:CAC is either compounding or eroding. Most subscription businesses don’t find out which until it’s too late.
Subscription businesses face a growth paradox familiar to every operator who has tried to scale one: the metrics that look healthy in a dashboard — subscriber growth, MRR, ROAS — do not predict the economics that actually matter. CAC climbs as you exhaust high-intent audiences. Churn compounds in cohorts you did not model carefully enough. And because marketing and finance measure LTV:CAC differently, there is no trusted number that anyone is making capital allocation decisions from.
Exactius deploys a cross-functional squad inside subscription businesses and builds the LTV:CAC infrastructure — connecting ad platform, CRM, payment processor, and subscription data into a single signal via Violet. Then we operate the Capital Allocation Loop: weekly reallocation of budget toward channels and cohorts producing the best contribution margin, away from those that look efficient on a platform dashboard but erode margin over time. Not a report. A running system.
Results from this model include $14M in incremental contribution margin in 9 months and recurring revenue growth from 15% to 50% of total revenue within a partner portfolio. The constraint is rarely creative or channel strategy — it is a measurement problem that prevents the right capital allocation decisions from being made.
Questions about subscription growth
Frequently asked
Do you work with early-stage subscription businesses?
We work best with subscription businesses that have product-market fit and are scaling — typically $5M+ ARR. If you're pre-scale, book a call and we'll tell you honestly if the timing is right.
How do you handle the LTV:CAC measurement problem?
Violet connects your ad platforms, CRM, payment processor, and subscription management system into a single LTV:CAC model. We build the predictive LTV layer so you're allocating capital against the right signal.
Can you work alongside our existing growth team?
Yes. We embed alongside your team, not instead of it. Most partners have internal performance or CRM functions — we operate as a single squad covering the gaps and elevating the overall system.
What is the Growth Operating System?
The Growth Operating System (GOS) is the methodology Exactius deploys inside subscription businesses — developed by David Manela. It combines a Capital Allocation Loop, Growth Infrastructure powered by Violet, and a cross-functional squad to replace ad hoc campaign management with a system that compounds LTV:CAC over time.
How long before we see results?
Attribution and LTV:CAC clarity typically improves within the first 30 days as Violet goes live. Retention and acquisition improvements compound from month 2 onwards as the Capital Allocation Loop runs weekly.
