How Mollie should run LinkedIn ads.
SMB fintech is the good end of B2B paid social: high volume, a short-ish cycle, and a self-serve signup. The trick is optimising for the lead that activates, not the form fill.
Analysis built with paid.social, the ad-planning tool from Jonas Sluijs, former Meta growth leadThis is B2B paid social at its most winnable. Mollie sells to 250,000-plus SMBs with a transparent, self-serve product, so the sales cycle is short and the buyer, a founder or finance lead, is reachable. That's the opposite of enterprise, where deals close in boardrooms. LinkedIn's precision on job title and company size is the edge; the risk is the usual B2B trap of buying cheap form fills that never open an account.
So optimise to the qualified lead or the activated merchant, not the raw lead. Send the activation event back so the platform learns which leads matter, gate the offer just enough to filter tyre-kickers, and run a Meta retargeting layer underneath, because SMB owners live there too and it's cheaper than LinkedIn for warm follow-up.
Specific beats clever in B2B. No catalogue here; the ad has to name a real pain and back it with proof. Two angles: the switch, and the cost.
How we built this plan
We modelled the economics from Mollie's public pricing, merchant count, and revenue, plus B2B SMB benchmarks for LTV and lead quality. The derived numbers are estimates, not Mollie's data, meant to show what winnable B2B paid social looks like and what "good" is.
