Why engineering firms operators use the ltv:cac ratio.
Calculate the ratio of customer lifetime value to acquisition cost. Industry benchmark is 3:1 — below that, you're subsidizing growth; above 5:1, you're probably under-investing in acquisition.
Engineering firms — civil, structural, mechanical, electrical — are professional services businesses with unique constraints: project-based revenue, deep specialization, and complex stakeholder management. SAZ helps engineering firms scale revenue, productize services, and embed AI across project delivery.
