How Much Should a Startup Spend on Marketing?

There's no single right number for a startup marketing budget. But there is a right way to think about it, and a realistic range for most seed-stage B2B startups.

Here's how we help founders set one.

Budget for Learning First, Scale Second

At seed, your marketing budget has one job: find a channel that works. That means spending enough to get a real signal, but not so much that you burn runway on a channel you haven't proven.

Once a channel works, the question flips. Now you're asking how much more you can put in before returns drop.

The Four Buckets

1. People

Who does the work. Founder time, a hire, a fractional lead, an agency, or an embedded team. This is usually the biggest line.

2. Paid media

Ads on Google, LinkedIn, Meta, or elsewhere. To get a meaningful read on a channel, we typically see $1,500 to $3,000 a month per channel.

3. Tools

CRM, email, SEO, analytics. Keep this lean. Most seed-stage stacks can run on a few hundred dollars a month.

4. Content and creative

Design, video, case studies, and anything you outsource beyond your core team.

A Realistic Range

For most seed-stage B2B startups we work with, marketing support runs $3,500 to $10,000 a month, plus $1,500 to $3,000 per paid channel if you're running ads.

Where you land depends on:

• Your sales motion. Outbound and SEO lean on people and time. Product-led growth often needs more paid spend.
• Your deal size. Higher contract values can support a higher CAC.
• Your runway. Budget for at least 90 days per channel test. Cutting at week three tells you nothing.

How to Know It's Working

• CAC by channel compared to customer value.
• CAC payback in months.
• Pipeline created per dollar spent.

For ReadyFestive, disciplined spend brought CAC to $16 with an 8:1 LTV to CAC ratio. That's the kind of number that justifies putting more in.

When to Spend More

• A channel has a CAC you can afford, and it holds as you add budget.
• You've just raised and have a clear plan for the money.
• Sales can handle more pipeline than marketing is creating.

If none of those are true, more budget usually means more waste.
