The short version: two different models
Capvant and iwoca both help UK businesses access funding, but they work in different ways. iwoca is a funding provider in its own right, so you apply to iwoca and iwoca assesses your business and makes the decision. Capvant is a marketplace, so you make one short request and we put it in front of a network of vetted funding partners who can come back with competing offers, and Capvant itself does not make the credit decision.
Neither model is automatically better. A direct provider can mean a simple, single relationship. A marketplace can mean you see more than one option from a single request. The sections below set out the differences so you can judge for yourself, and we would always suggest checking iwoca's own site for their current products, eligibility and pricing.
