The metric that tells investors we can grow fast — and profitably.
Venture capitalists love big visions, but they also love math. And one number in particular tends to get their attention: Customer Acquisition Cost to Lifetime Value (CAC:LTV) ratio.
Simply put:
A healthy SaaS benchmark is 3:1 — meaning for every $1 you spend to get a customer, you make $3 back over time.
When we showed VCs that our CAC:LTV ratio was far above that benchmark, conversations got a lot warmer.
1. Efficient Acquisition Through Product‑Led Growth (PLG)
We’ve built our Trusted AI Agent Builder to sell itself:
Result: 63% of paid conversions come from self‑serve signups — without heavy sales overhead.
Impact: Lower CAC because our product, not our sales team, drives the bulk of acquisition.
We learned early that merchants who set up 3+ agents in the first 30 days stay with us much longer. So we redesigned onboarding to:
Result: Churn dropped by 42% and average customer lifetime increased by over 2x.
Impact: Higher LTV because customers get more value over a longer relationship
Once merchants see results from a single agent, they naturally want more. Our Agent Marketplace offers:
Result: 37% of customers expand into higher‑tier plans within 90 days.
Impact: LTV grows without needing to acquire a new customer.
We use paid acquisition only where the unit economics work:
Result: Paid CAC is predictable and pays back in under 3 months.
When we walked investors through the funnel — from low‑cost acquisition, to strong retention, to built‑in expansion — the reaction was clear:
“This isn’t just growth. This is efficient growth.”
A strong CAC:LTV ratio tells investors:
It signals that every dollar they invest in acquisition will return multiples, not just in theory, but in proven historical performance.
Vision sells the dream, but metrics close the deal. Our above‑benchmark CAC:LTV ratio proves we can scale without sacrificing unit economics — and that’s exactly what investors want to see.
