Every founder I meet arrives with a channel list. Twelve items, sometimes twenty. None of them ranked. The three questions below force the ranking — and they are the only three that matter before the Series A closes.
The most expensive mistake in a Series A go-to-market plan is not picking the wrong channel. It is trying to run eight channels at once because nobody on the team knows which two will move the number. The twelve-item spreadsheet is a symptom of an operating team that has not yet done the work of disagreeing with itself. My job is to force the disagreement into the room before the capital gets lit.
What follows is the three-question sequence I run with every new engagement, in order. Question one does the most work. Question two kills most of what survives. Question three is the operating question you will answer every week for the life of the engagement.
Where does your current best customer actually spend attention?
Not where you want them to be. Not where they “should” be. Where the customers who already love your product currently, concretely, spend hours of attention every week — professionally, socially, or both. Write it down as behavior, not demographic.
Most founders answer this question with platform names. Wrong answer. The right answer reads like: “They subscribe to three trade newsletters and lurk in two private Slack communities; they do not read LinkedIn but they do listen to one category podcast on the drive home.” That is a behavior map. From a behavior map, the channel list writes itself. From a platform guess, every channel looks equally plausible, which is the same as no channel looking right.
Demographic targeting is a fallback for teams that did not do the behavior work.
Which two channels can you credibly win at with the team you have right now?
Not hire for. Not “once we have the budget.” The team you have, this quarter. The Series A mistake is pretending you will hire your way to channel competency inside a round that is supposed to fund eighteen months of learning. You will not. You will spend four of those months hiring, two onboarding, and the rest of the round relearning what you could have learned in six weeks on the channels your current team already operates.
The right answer to this question is almost always two. Sometimes one. Very rarely three. Every channel you add past two halves the attention the first two get, and channel wins come from attention.
- 01Has someone on the team operated this channel to a direct-response outcome in the last 18 months?
- 02Do we have the creative capacity — brief + production — to feed it weekly?
- 03Do we have the measurement instrumentation to tell a "yes" from a "no" in four weeks or fewer?
Three yeses on two channels means you have a plan. Two yeses on one channel means you have a narrower plan and you will learn faster. Any other combination means you are about to spend money on a research expedition, which is a fine use of money if you call it that, and a terrible use of money if you call it growth.
What does a “yes” on a channel actually look like — in numbers you will defend to the board?
This is the question most go-to-market plans never answer in writing. The team picks a channel, funds it, runs it for a quarter, and ends up arguing about whether it worked. The argument happens because nobody wrote down what “yes” would have looked like before they started.
The decision you need to commit to, in writing, before spend begins:
- The metric: CAC, payback period, qualified pipeline volume — whichever one your model actually runs on.
- The threshold: a specific number. Not a range. One number that separates "we scale this" from "we kill this."
- The window: how many weeks the channel gets to reach the threshold before it gets cut.
- The owner: whose name is attached to the decision at the threshold, so the decision gets made.
Every channel bet needs a kill criteria written down before the first dollar moves.
If you cannot write the “yes” as a single sentence — “yes means X dollars CAC on Y volume by week Z, signed off by [name]” — you do not yet have a channel plan. You have a channel wish. The difference is that wishes are renewable and plans are falsifiable.
Why three questions, not twelve.
Every growth plan I audit has twelve items in the spreadsheet. Three of them matter, and those three are always answerable by the three questions above. Everything else is decoration — plausible channels the team could not credibly operate, speculative audiences without behavior maps, metrics defined in ranges broad enough to guarantee an argument at quarter-end.
The spreadsheet has twelve rows because it was built by consensus. A good growth plan is not built by consensus. It is built by a single operator who has made the three hard choices and can defend them to the team and to the board. If I am running the engagement, the three choices get made in the first ten days. If nobody is running the engagement, the twelve-item spreadsheet stays in the deck and the round gets spent arguing about it.
A final operating note.
You will get the first two channels wrong sometimes. Not always — but sometimes. That is fine. What is not fine is building a plan that cannot tell you whether you were wrong. The three questions above exist so that a wrong answer takes six weeks to surface, not six months. Series As that lose their rounds inside twelve months are almost always the ones where the wrong answer took the whole twelve to surface.
