The categories of capital, ordered by cost and structural reach.

The categories of capital, ordered along one axis of rising cost of capital and structural reach, from keenest price and narrowest box on the left to highest cost and widest reach on the right.
Order	Category	Where it sits
1 of 5	Clearing & relationship banks	Keenest price, narrowest box
2 of 5	Asset-based & asset-finance	Lends against what you own
3 of 5	Challenger & specialist banks	Underwrites on its own terms
4 of 5	Sponsor & searcher specialists	Backs the operator as much as the asset
5 of 5	Private-credit & direct-lending funds	Flexes around the event and prices for it

How the categories of capital relate on cost and structural reach.

The whole market, mapped.

Banks are no longer the whole of the market. A UK lower-mid-market company can today be funded by clearing and relationship banks, a deep field of challenger and specialist banks, private-credit and direct-lending funds, and asset-based and asset-finance lenders — with a handful within those ranks who will also back sponsors and first-time operators. Each lends to its own appetite, across its own part of the capital structure. Solon maintains a live map of that market and approaches it selectively, so the process tests suitable counterparties for a given deal rather than defaulting to the obvious one.

The categories of capital

Five categories of lender, each with its own appetite and its own part of the structure. How they compare on cost, flexibility, speed and leverage, at a glance.

The categories of capital compared on cost of capital, flexibility, speed to a decision and leverage appetite. Each rating is from 0 to 4. A higher cost-of-capital rating means more expensive, not better; for the other three a higher rating means more of that attribute. This is a trade-off across categories, not a ranking; cost rises with reach.
