Product-Channel Fit

The question

Take the acquisition channel you keep hearing works — the one a competitor appears to run beautifully — and ask what that channel demands of a product before it will carry one: how quickly the value has to land, how broad the appeal has to be, how much a single customer has to be worth in a year? Set your own product honestly beside those demands and the usual answer is that the channel was never available to you, which is a far cheaper thing to learn this morning than after a quarter of spend.

The idea

Brian Balfour was VP of Growth at HubSpot before founding Reforge, and in July 2017 he published Product Channel Fit Will Make or Break Your Growth Strategy, one of a linked set of essays laying out four fits a growing business has to hold at once — market-product, product-channel, channel-model and model-market. The argument fits in a sentence: products are built to fit channels, and channels do not mould to products. His reasoning is about control rather than cleverness. You own every decision inside your product. You own none of the rules of a channel — not the auction, not the ranking, not the interface that gets switched off one Tuesday — so the only thing available to bend is the thing you own. Each channel then arrives with requirements attached. Virality wants value that lands almost immediately, a proposition broad enough that most of someone's contacts qualify, and a product the network genuinely improves. Paid marketing wants that same speed to value and a transactional model underneath it. Search built on what users write wants users who'll write something, and a reason for them to bother. Balfour's history of games carries the point: PopCap couldn't lift web-portal games onto Facebook, Zynga built for Facebook, then Zynga couldn't lift those onto mobile, and Supercell built for mobile. Two mornings on, nineteen candidates get scored and three get tested. This filter runs first, and it runs on paper.

The framework

01
Two lists, and the overlap between them.
Write the channel's requirements down first, in its terms, before you write a word about yourself — speed to value, breadth of appeal, whether the network improves the thing, whether users produce anything worth indexing. Then write what your product actually is, using evidence rather than ambition: how long a real customer waits for a real result, who it genuinely suits, what your users have in fact produced. Fit is the overlap, and it's a shorter list than anybody expects. One channel at a time, because the requirements aren't interchangeable and a blended answer tells you nothing.
02
Your price has already picked the channel.
The next essay in Balfour's series makes the harder half of the argument: what you charge decides which channels can carry you. Very low revenue per customer leaves only the channels nobody invoices you for — virality, organic search. A middling figure supports paid, if the payback holds. Higher amounts start to fund content, inside sales and partnerships, and only genuinely large contract values pay for named people selling outbound. His danger zone is the middle: priced too high for the frictionless channels and too low to afford a human being. That's a model problem wearing a marketing costume.
03
Change the thing you own.
When product and channel don't meet, there are two moves and only one of them is yours. Balfour's account of Pinterest is the clean case: it had grown on viral sharing into Facebook's feed, Facebook closed those interfaces, and Pinterest moved to search built on what its users had made — changing the product from a social one into a personal utility to do it. The other move is to rule the channel out in writing, with the reason attached, so nobody proposes it again in March as though it were a fresh idea.
04
Read a rival's channel backwards.
A competitor visibly winning in a channel is evidence about their product, not proof about the channel. So run the inference the other way: from what the channel requires, work out what must be true of theirs — how fast it pays off, how wide it goes, what a customer is worth to them in a year — and set that beside your own. Very often you'll find they're serving a different buyer at a different price, which is the whole explanation. Copying the channel without the product characteristics underneath it buys you their invoice and none of their result.
