Founders often miscalculate Customer Acquisition Cost by measuring the cost to acquire a trial user, not a paying customer. This creates a dangerously optimistic view of unit economics. True CAC must account for the trial-to-paid conversion rate (e.g., if trial CAC is $130 and 1 in 3 convert, true CAC is ~$400).

Marketers fail with premium offers because they don't adjust pricing to match higher lead costs. If a premium lead costs 5-10x more than a free lead, the product price must be 5-10x higher to maintain profitability. Free and premium are entirely different, non-interchangeable acquisition models.
For products with high trial churn, replace the standard "try before you buy" model. Instead, charge users upfront and offer a rebate or a free second month if they complete a key activation task. This creates commitment and incentivizes the exact behavior that leads to long-term retention.
GoProposal viewed high-touch, proactive onboarding as part of their acquisition cost. Before a trial user even entered their credit card, the team would manually set up their account with brand assets. This "shock and awe" approach wowed customers and dramatically increased conversion.
Lifetime Value (LTV) is meaningless in isolation. The key metric for investors is the LTV to Customer Acquisition Cost (CAC) ratio. A ratio below 3:1 indicates you're overspending on growth. The 3:1 to 5:1 range is healthy, while anything over 5:1 is world-class and attracts premium valuations.
SaaS companies often use the traditional top-down sales funnel as their mental model. However, this model is fundamentally flawed because it ends at the 'close' and completely ignores the recurring revenue component, which is the lifeblood of SaaS. The 'bow tie' model is a more accurate representation.
The goal of a free trial isn't just to let users 'try before they buy.' It's to integrate your solution into their workflow so that its eventual removal creates a powerful sense of loss and deprivation. This feeling of losing the solution, rather than the initial desire for it, is what drives conversion.
Adding qualification steps to a sales funnel weeds out bad-fit leads. This increases cost-per-lead but lowers overall customer acquisition cost (CAC) and boosts morale by letting salespeople focus only on high-intent, closable deals.
The company heavily invested in product trials via paid search, but analysis revealed these leads had a mere 5% win rate and the lowest average contract value. This demonstrated that their primary lead source was also their least efficient for generating actual revenue.
To profitably scale a SaaS with paid ads (Meta, YouTube), you cannot rely on low-ticket monthly subscriptions. The customer acquisition cost will almost always be too high to be sustainable. You must have a high-ticket enterprise plan to ensure a positive return on ad spend from day one.
Don't overcomplicate defining value. The simplest and most accurate measure is whether a customer will exchange money for your solution. If they won't pay, your product is not valuable enough to them, regardless of its perceived benefits.
