How Much of a Founder's Week Should Go to Marketing?

How many hours of a founder's week should go to marketing?

Between 4 and 12 hours of a 40-hour week, or 10% to 30%, with the exact figure set by whether a marketing channel already works for you. The arithmetic is plain: 40 × 0.10 = 4 hours at the low end and 40 × 0.30 = 12 hours at the high end.

Everything below is labelled as what it is. The shares are Kanso's judgement, the hours follow from them by multiplication, and the only outside claims are two practitioner pages cited for method.

• The range is 10% to 30% of working hours, and the right point in it depends on your situation, not your ambition.
• The highest share, 25% to 30%, belongs to the stretch with first customers and no channel you can repeat.
• Four hours a week is the floor in every situation.
• The largest single use of the hours is talking to prospects and customers, about 40% of them.
• You can check your own number with a one-week time audit, then compare it with the table below.

What do the pages ranking for this question already say?

The two pages read for this article cover time management in general, and neither gives a share of the week for marketing. Hustle Insider's guide for startup founders recommends prioritising, time blocking, single-tasking, delegating, the 80/20 principle, deep work, shorter meetings and saying no.

ICUBE UTM's page, from a startup program, recommends a time audit, SMART goals, the Eisenhower matrix for urgent versus important work, delegation and protecting your own energy. Both are sensible and both are generic: a founder could follow every tip and still not know whether two hours or twenty a week belong to marketing.

That gap is the reason this page exists. It borrows two methods from them, the time audit and time blocking, and adds the thing they leave out, a number with its working shown.

Why does this page give a model instead of a statistic?

Because the research behind this page found no measured figure for how much of their week founders should give to marketing, and an invented one would be worse than none. The package listed no authoritative primary source on the topic, and its search results were guides, a video and forum threads.

So the page does the one honest thing available: it states its assumptions as assumptions. A model with visible inputs can be argued with, changed and tested, which a bare statistic quoted from nowhere cannot.

What would change this opinion is simple to say. A study that recorded founders' marketing hours alongside a measure of customer growth, with its method published, would replace the guesses in the table with evidence, and this page should then be rewritten around it.

How does the model work?

The model multiplies your weekly working hours by a share chosen for your situation, then raises the result to four hours if it comes out lower. It has three inputs and one rule.

marketing hours = working hours × situation share, with a minimum of 4

• Working hours. The hours you really work in a week, not the hours you plan to. Use the figure from a time audit if you have one.
• Situation. One of four rows in the table below, set by whether you have customers and whether a channel has produced them.
• The floor. Four hours, which is the smallest week in which conversations, distribution, creation and review can all still happen.

That covers conversations with prospects before a deal, publishing, sending work out and reading the results. It excludes product work, support for people who already pay, a deal already in negotiation and fundraising, so count those elsewhere and do not count any hour twice.

What share of the week fits each situation?

The share runs from 10% to 15% while you are still building the first version up to 25% to 30% when you have first customers but no channel you can repeat. The table gives the share, the hours for a 40-hour and a 50-hour week, and what the hours are for.

How it was put together: the four situations are Kanso's own division of a young company's marketing, the shares are Kanso's judgement, and each hours figure is the working week times the share. For row 2, 40 × 0.25 = 10 and 40 × 0.30 = 12, then 50 × 0.25 = 12.5 and 50 × 0.30 = 15.

As a cross-check, Kanso's earlier 90-day marketing plan for technical founders comes to 71 hours over 13 weeks, which the page itself rounds to 5.5 hours a week. Divided by a 40-hour week, 5.5 ÷ 40 = 13.75%, inside the 10% to 15% band of row 1. That plan is also a proposal, so the two figures agree with each other and prove nothing about founders.

Why does the stretch with first customers get the largest share?

Because with first customers and no repeatable channel, the scarcest thing you own is knowledge of who buys and how to reach them, and marketing hours are how you get it. This is an argument, not a finding.

In row 1 there is little to market yet, so the hours go to learning the problem from prospects. In row 3 the knowledge exists, so the hours buy repetition instead of discovery, and the need for them falls. In row 4 the founder's hours move to the parts only the founder can do.

Hustle Insider describes the 80/20 principle as the idea that a small share of activities often produces most of the results, and suggests founders look at which marketing channels contribute most. That is a general principle, not marketing data, but it explains the shape of the table: spend the most while you are finding the channel that matters, then concentrate on it and stop spreading effort.

What should the marketing hours be spent on?

Spend the largest part, about 40%, on conversations with prospects and customers, then split most of the rest between making work and sending it out, with a tenth for reading the results. The split is Kanso's opinion, shown for a 10-hour marketing week and for the 4-hour floor.

Check the sums: 40% + 25% + 25% + 10% = 100%, and 4 + 2.5 + 2.5 + 1 = 10 hours. In row 1, when there is nothing to publish, move the creation and distribution shares into conversations as well.

Conversations come first because everything else depends on what they teach you. If your channel is LinkedIn, a posting system built from your actual work shows how to fill the creation and distribution hours from what you already do. For the review hour, the weekly marketing metrics a seed-stage founder should review lists what to read.

How do you find out how much of your week marketing takes now?

Run a time audit for one week: record each block of work under a category, then divide the marketing hours by the total. ICUBE UTM describes a time audit in three steps, which are to set up the audit with a tracking method you will really use, to record your activities throughout the period, and to analyse the patterns for time that can be delegated or cut.

1. Choose a spreadsheet or a tracking app that is easy enough to use all week. ICUBE UTM warns against over-committing to a method.
2. Use four categories: marketing as defined above, product, customers who already pay, and everything else. Kanso added this step so the audit lines up with the model.
3. At the end of the week, divide marketing hours by total hours worked, then compare the result with your row in the table.

Here is a hypothetical founder, not a case study. They work 45 hours, have first customers and no repeatable channel, and the audit shows 3 marketing hours: 3 ÷ 45 = 0.067, or about 6.7%.

Row 2 asks for 25% to 30%: 45 × 0.25 = 11.25 hours and 45 × 0.30 = 13.5 hours. The gap is 11.25 − 3 = 8.25 hours at the low end and 13.5 − 3 = 10.5 hours at the high end, which is the size of the change this founder is being asked to make.

How should the marketing hours fit into the week?

Put them in fixed blocks on the calendar, so they are scheduled work and not whatever time is left over. Hustle Insider says time blocking reduces context switching and improves concentration, which is its claim and not a measured result here.

The table shows one way to place a 10-hour marketing week using the split above: two 2-hour conversation blocks, one 2.5-hour creation block, five 30-minute distribution slots and a 1-hour Friday review. It is an illustration of the model, not a schedule any founder has tested.

Move the blocks to suit your energy, since Hustle Insider also advises putting demanding work in your highest-energy hours. Keep the proportions and the blocks fixed even when you move them.

When should a founder spend less time on marketing?

Only when the evidence for the next situation is in, not when the week gets busy. These rules are Kanso's, they are untested, and they exist to stop the busiest weeks from deciding the answer.

1. Stay in row 1 or 2 until a customer conversation has happened in each of the last two weeks.
2. Move from row 2 to row 3 only when at least one channel has produced a customer you can trace to it and you can write down how.
3. Move from row 3 to row 4 only when someone else has run the channel for a month without you rewriting everything they make.
4. If eight weeks at the top of your band produce no traceable conversation, change the channel, not the hours.
5. Never go below the four-hour floor, in any row.

The handover in rule 3 is the point at which a hire becomes a real option, and the signals for a first marketing hire cover it.

When is this model wrong?

It is wrong whenever your situation is not one of the four rows or when the founder's hours are not the limiting resource. The shares have not been tested on any group of founders, so use them as a starting point and replace them with your own numbers.

• Where the sales conversation is the main marketing, as in a business that sells to a few large buyers, the line between marketing and sales blurs and the model double counts.
• Where a cofounder or teammate already owns marketing, apply the model to their hours, not the founder's.
• Where the product itself brings the next user, product hours may do more for growth than any row here assumes.
• Where the week is far shorter or longer than 40 to 50 hours, the shares still apply but the four-hour floor may need a second look.

The simplest test is to run the model for eight weeks, log the hours with the audit, and compare them with what came back. If the return is flat while you sat at the right share, the problem is the channel or the message, not the allocation.

What is documented and what is Kanso's analysis?

Very little on this page is documented fact, and most of it is Kanso's analysis. The two lists below keep them apart.

Documented, from the sources named in each item

• Hustle Insider recommends time blocking, the 80/20 principle, deep work, delegation and saying no, and says time blocking reduces context switching.
• ICUBE UTM describes a three-step time audit: set it up, record activities, analyse the pattern.
• Kanso's own 90-day plan states 71 hours over 13 weeks, and itself calls the hours a proposal.
• The research package for this page found no published figure for founders' marketing hours.

Analysis, which is Kanso's opinion and untested

• The four situations and their shares, 10% to 15%, 25% to 30%, 15% to 20% and 10%.
• The four-hour floor and the reason given for it.
• The 40%, 25%, 25% and 10% split of the marketing hours.
• The example week and the rules for moving between rows.
• The cross-check against the 90-day plan, 5.5 ÷ 40 = 13.75%, which is Kanso's own arithmetic on its own estimate.
