If you run marketing at a B2B fintech and your last paid program burned through six figures without producing pipeline, the channel probably isn't the problem.

It’s likely more an issue of the way the account was built.

We've written separately about the two universal mistakes we see across B2B paid media. That is, running Google Ads for B2B like it's a B2C account and confusing ABM-as-strategy with ABM-as-product.

This post is about the third problem, which is vertical-specific. It shows up most acutely in fintech, where the cost of getting it wrong is highest, and the leverage from getting it right is largest.

Here are the three things we see fintech founders get wrong about paid media on almost every intro call.

1. Compliance-aware creative

Most agencies write fintech ads the same way they write SaaS ads. That doesn't work.

If your product touches institutional money, the kinds of claims you can make in copy are tightly constrained. An agency that hasn't worked with that constraint will write ads that promise returns, imply guarantees, or make comparative performance claims, and either get rejected by Google's review process, get the account flagged, or worse, get the company in front of regulators.

The fix is not to write boring copy. The fix is to know which specific claims are off-limits and to build creative that is tactically specific without making the claims that get accounts in trouble. That's a skill that comes from working with fintech accounts, not from reading platform policy docs.

2. ICP segmentation by AUM tier and firm type

Service providers, family offices, and sovereign wealth funds are not the same kinds of buyers. If you lump them all into the same audience, you are going to get terrible results.

This is the single biggest mistake we see in fintech paid media accounts. Campaigns are structured around generic personas: "investment professional," "finance leader," "buy-side decision maker."

This approach to targeting collapses real segmentation differences. The result is creative that speaks to no one specifically and lands with no one specifically.

The fix is to segment by AUM tier and firm type at the campaign level, not the audience-rule level. Different campaigns, different creative, different landing pages, different bids. The platforms reward this. The buyer journey demands it.

Maybe you don’t have the budget to run several highly segmented campaigns. That’s fine. Just pick 1 or 2 segments at a time that are the highest priority.

3. Patience with longer sales cycles

B2B fintech sales often take six to twelve months. Advertisers that test for a month and then pull the budget because they think “the ROI isn’t there” misunderstand what advertising is supposed to do.

Actually, there are several things going on in this situation.

First, they are comparing a mature channel—usually founders' outbound sales—with a new channel. Probably the founder was not getting sales right away with the first version of his pitch, so expecting paid media to work in the first month is not realistic.

Second, even when the messaging and the funnel are perfect, ad accounts take time to build frequency (in the case of LinkedIn) and build up negative keywords (in the case of Google Ads).

The role of paid media in a long-cycle B2B fintech business is not to close a deal in the first 90 days. It's to consistently put your brand in front of a finite set of buyers so that when one of them enters an active buying window, maybe next quarter, maybe next year, your name is the one they recognize.

This is why B2C advertisers are always testing brand recall. Byron Sharp has written very sharply about this in How Brands Grow.

That requires patience that most fintech marketers don't have when they're being pressured by a CFO to justify the line item or by sales leaders to produce leads. This often results in accounts pulling spend at the exact point where the program was about to start producing a real pipeline, which is the worst thing you can do because the testing budget ends up wasted.

What this looks like when it's built right

I built the inbound marketing function at a leading institutional finance data provider, scaling it from nothing to a high-ROAS program inside a year.

It was a typical B2B fintech company with a powerful sales team constantly pushing marketing to produce more leads.

The constraints there were the constraints we now design around for every fintech account we run: regulated messaging, segmented buyer base, sales cycles measured in quarters, not weeks.

That experience informs how we run paid media for B2B fintech today. With tight match types, aggressive negative keywords, ICP segmentation by firm type, creative that respects compliance constraints, and the patience to let the program compound.

If your current program isn't producing sales opportunities, the answer probably isn't to cut spend or change channels. It's to look at how the account is built and ask whether any of these three things have actually been addressed.
