Burn multiple is the one efficiency metric with nowhere to hide — it grades the whole company, not just sales and marketing. Here's how to calculate it correctly, what real benchmark data says about "good," and why AI startups aren't as efficient as anecdotes claim.

Lighter Capital analyzed cash efficiency across 83 private B2B SaaS startups with ARR ranging from roughly $250K to $22M.

What it shows is that cash efficiency in SaaS is not a maturity story. It's an operating model story.

Instead of asking, “did we find product-market fit,” founders now have to find an operating framework that enables the business to flex to meet the needs of a fluid market.

SaaS is transforming on multiple fronts all at once with the rise of AI. AI is making software faster and cheaper to build, while making growth, distribution, and pricing more complex.

In plain English: sales and marketing spend is not going as far as it used to.

The pervasive narrative that "AI will kill SaaS" is fundamentally flawed. It misunderstands how AI actually creates measurable value in the enterprise. Far from being a platform killer, software is the essential infrastructure that allows AI to move beyond a simple querying tool and become a true force multiplier.

Startup accelerators offer an attractive funding and support option to early-stage companies. While they often get lumped together with other startup funding options like incubators, angel investors, and early-stage venture capitalists, accelerators are their own special animal.
