Sales and go-to-market · Answered by Golden Section from more than 400 B2B software companies observed
The real question is how much marketing it takes to supply at least 30% of your account executives' pipeline. Our starting point is marketing at about 20% of the total sales and marketing budget, provided that keeps the AEs busy alongside their own relationship building and outbound. At SaaS Capital's 2026 median of 23% of ARR for sales and marketing, that is roughly $230K at $5M. Finding the channels takes trial and error, and they change: in 2026 email has degraded, while paid advertising, generative engine optimization and conference attendance do more of the work. Study how your customers learn about new offerings and build the motion from that. Sales efficiency sets the ceiling; above $1.00 of sales and marketing per $1 of new ARR, fix the funnel before adding budget. Start by tagging every opportunity with its source.
Size marketing to supply 30% or more of AE pipeline, starting near 20% of total sales and marketing spend. Increase it only where a channel's cost per qualified opportunity and the company's sales efficiency both hold as spend rises; below that bar, reallocate before you add.

A marketing budget set as a percentage of revenue answers the wrong question. Marketing's job at this stage is to keep account executives busy with qualified opportunities they did not have to find themselves, and 30% or more of their pipeline is the bar we use. What that costs depends on channels, and channels move. Email used to carry much of this load; in 2026 it has degraded, and paid advertising, generative engine optimization and well-chosen conferences are working better. The way to know which fit your market is to analyze how your customers learn about new offerings, then test those channels with enough volume to judge. Buyer personas give that research structure, and the sales funnel and pipeline creation plays turn cost per lead into cost per closed dollar of ARR.
The ceiling comes from the sales efficiency ratio. If total sales and marketing spend already costs more than $1.00 per $1 of new ARR, more marketing mostly buys leads for a funnel that loses them. Our budget creation play describes a management team that planned for $0.45 of efficiency when the top quartile struggles to beat $0.75.
A $5M company spends $1.1M on sales and marketing, $300K of it on marketing, and marketing sources 18% of AE pipeline. Tracing last year's qualified opportunities, email sequences cost $90K and produced 4, a regional conference program cost $80K and produced 12, and paid search cost $130K and produced 10. After interviewing twenty customers about how they find new tools, it cuts email to maintenance, adds a second conference, trims search to its best keywords and moves $40K into content built for the questions buyers ask AI assistants. Marketing spend falls to $250K, closer to 20% of sales and marketing, and marketing-sourced opportunities reach 31% of AE pipeline the next year. All figures are invented for illustration.
A company entering a new vertical or launching a product may need to spend above median for a defined period; treat that as an investment with its own budget and review date, not as the new run rate.
From the Golden Section mistakes list, each paired with the play that prevents it.
Judging marketing on cost per lead or impressions rather than cost per closed ARR funds the wrong channels.
Channel trial and error only works if each test runs at enough volume to produce a verdict.
Conferences can work, but a large booth expected to carry the process on its own rarely does; start small.
Brand spend that outruns financial health consumes budget that measured channels could have used.
In the order we would run them. Each is on its own page, most with a free Excel template.
Structures the customer research that shows how buyers learn about new offerings.
Gives stage conversion so channel cost can be measured per closed dollar.
Quantifies how much top-of-funnel volume the bookings target needs, and what share marketing must supply.
Sets the ceiling that decides whether more spend is justified.
Turns channel economics into a budget tied to realistic efficiency.
Sales & marketing plays Go-to-market, funnel and efficiency plays together decide how much marketing a company can use well.
Enough to supply 30% or more of your account executives' pipeline, which in our view usually means about 20% of total sales and marketing spend. SaaS Capital's private-company median is about 8% of ARR, and equity-backed companies spend roughly twice what bootstrapped ones do. Move from there according to cost per qualified opportunity and overall sales efficiency.
There is no correct percentage of revenue, only a correct return. We size marketing as a share of sales and marketing, about 20%, and test it against whether it keeps AEs supplied with 30%+ of their pipeline. Raise it only for channels that hold their cost per qualified opportunity as spend grows.
Email has degraded as a channel, and paid advertising, generative engine optimization and conference attendance are doing more of the work. The right mix still depends on how your customers learn about new offerings, so ask them and test with enough volume to judge.
A marketing channel with demonstrated CAC payback under 18 months is exactly what non-dilutive debt is for. We do not fund experiments; we fund more of what is already converting.
