The Modeling System That Powers 30%+ Revenue Growth

The Modeling System That Powers 30%+ Revenue Growth

Most brands forecast from gut feel and ROAS. CTC runs on four interlocked proprietary models that produce a daily P&L forecast with 3.1% accuracy across more than $3 billion in GMV. In Part 2 of the Canon series, Luke Austin breaks down each model, how they connect, and what a Profit Engineer actually does with them Topics covered: * Why a single ROAS number can't run a business * The Spending Power Model — ACoNS curves and what spending power actually tells you * The Retention Model — forecasting returning revenue cohort by cohort * The Event Effect Model — how to get daily precision without breaking monthly targets * The Creative Demand Model (teased — full breakdown in the creative strategy episode) * How these four models wire together into a connected forecast system * What R-squared below 0.6 signals about your retention data * The three optimization points every brand should know: max CM, max revenue, max LTV CM Key stat: 3.1% forecast accuracy across $3B+ in GMV managed — producing 30%+ revenue growth and 40%+ contribution margin growth.

Why Ritsu Switched Email Platforms Mid-Growth (And What It Actually Took)

Every dollar spent on SaaS is a dollar that does not go into ads. In this episode, Luke Austin sits down with Gil Dyen, Head of Marketing at Rutsu Barefoot, to walk through a real email and SMS platform migration to Omnisend — what drove the decision, what the process actually looked like, and how a 60,000-contact list got fully migrated in under 30 days with less than a working day of direct involvement. Gil runs marketing at a mid-7-figure DTC footwear brand that has sold 45,000 units in its first 18 months, with a clear mandate: keep SaaS costs lean, reinvest every freed dollar into Meta spend and creative, and build the retention engine that takes the brand from 12% returning customers today to 45% by year three. Topics covered in this episode: * Why a bootstrapped DTC brand audits its SaaS stack constantly * The two criteria that actually drive platform decisions: cost and time * How Omnisend managed the full migration, from contact database to flow automations * What the QA process looks like after a migration (and how long it takes) * The warm-up mechanics: 9 days to re-engage 60,000 contacts * Why Q4 is the wrong time to switch email platforms (and when to do it instead) * How an ESP migration becomes a flow audit opportunity * CTC's Omnisend integration inside Statlas for forecast-connected email tracking Show Notes: * Axon is offering $5K ad credit when you spend $5K.
