Before you quit, write the memo.

Not a journal entry. Not a motivational note. Not a resignation fantasy. Not a tweet thread about courage.

A memo.

One document that forces the decision into the open.

Quitting your job to build full-time is not a personality test. It is a capital allocation decision under uncertainty. You are reallocating time, money, energy, identity and downside risk from one path to another.

The Go-All-In Memo exists to prevent one mistake:

Using emotion to answer a question that requires evidence.

The first page

The memo begins with one sentence:

I should go all-in now because [business evidence] shows that [opportunity] is being limited by [specific constraint], and I have [runway] to pursue it responsibly.

If you cannot complete that sentence, you may not be ready.

Examples:

Weak:

I should go all-in because I believe in myself and hate my job.

Stronger:

I should go all-in because the business has reached €8,000 MRR, paid acquisition is generating qualified leads below target CAC, customer onboarding is now the main bottleneck, and I have 18 months of personal runway.

The memo is not asking whether the business is guaranteed.

It is asking whether the decision is rational.

Section 1: The business evidence

List the evidence.

Not vibes.

Evidence:

  • revenue;
  • active customers;
  • repeat usage;
  • retention;
  • paid conversions;
  • waitlist quality;
  • sales pipeline;
  • customer interviews;
  • inbound demand;
  • acquisition cost;
  • gross margin;
  • renewal behavior;
  • customer urgency;
  • referrals.

Separate strong evidence from weak evidence.

Weak evidence:

People liked my LinkedIn post.

Stronger:

23 strangers joined the waitlist from search traffic, and 7 replied asking for pricing.

Weak evidence:

Everyone says the idea is cool.

Stronger:

Five customers paid before the full product existed.

The first section should make the business look either more real or less real.

Both are useful.

Section 2: The constraint

Why now?

Do not quit unless full-time focus changes the slope.

Possible constraints:

  • too many customers to serve after work;
  • product velocity is too slow;
  • sales calls require daytime availability;
  • acquisition tests need daily iteration;
  • support is hurting retention;
  • content production is the growth bottleneck;
  • hiring or contractors require management;
  • partnerships are waiting;
  • opportunity window is time-sensitive.

Bad constraint:

I want more time.

Better:

We are losing qualified leads because I cannot respond during working hours.

Bad constraint:

I would grow faster full-time.

Better:

The last three growth experiments were delayed by 2–3 weeks each because I only had nights available.

The constraint must be specific.

Section 3: The runway

Write the real numbers.

Personal cash:
Monthly personal burn:
Minimum personal burn:
Business cash:
Monthly business burn:
Expected revenue:
Worst-case revenue:
Months of personal runway:
Months of business runway:

Do not use fantasy numbers.

Use actual bank balances, actual expenses and conservative revenue.

YC’s runway advice is written for companies, but the principle applies personally: lack of runway changes decision quality. If the clock is too short, founders often become reactive.

Your runway should let you make good decisions.

Section 4: The downside

Write the failure case without drama.

If this fails after 12 months, what happens?

Answer:

  • Can I get another job?
  • How long would re-employment take?
  • What reputation risk exists?
  • What financial damage would occur?
  • What relationships are affected?
  • What debt or obligations exist?
  • What skills will I have gained?
  • What assets remain?
  • What would make failure unacceptable?

A good downside analysis does not remove fear.

It gives fear shape.

Section 5: The opportunity cost of staying

Staying employed is not always safe.

Sometimes it is expensive.

Ask:

What do I lose by waiting six more months?

Possible costs:

  • slower product learning;
  • missed market timing;
  • lower customer trust;
  • slower content compounding;
  • inability to close sales;
  • founder energy decay;
  • competitor movement;
  • team momentum loss;
  • personal regret.

But be honest.

If waiting six months does not materially hurt the business, quitting may be premature.

Section 6: The all-in plan

Going all-in without a plan is not bravery.

Write the first 90 days.

Days 1–30: focus

One product priority
One acquisition priority
One revenue priority
One operating rhythm

Days 31–60: proof

Improve conversion
Talk to customers
Run channel tests
Ship key product changes

Days 61–90: scale or narrow

Double down on what works
Kill weak channels
Clarify hiring/contractor needs
Update runway plan

The plan should not include 25 priorities.

A founder who quits to become unfocused has not gained freedom. They have gained unmanaged time.

Section 7: The decision rule

Set conditions.

I will go all-in if:

Examples:

MRR reaches €5,000 and is growing for 3 consecutive months.
Paid acquisition produces 100 qualified leads below target cost.
We close 5 paid customers from outside our network.
The business requires more than 20 hours/week to avoid losing momentum.

Also write the opposite:

I will not go all-in yet if:

Examples:

All demand still comes from friends.
No one has paid.
The channel is unproven.
Runway is below 9 months.

Decision rules reduce self-deception.

The final page

The final page has only four options:

Quit now.
Wait and hit defined milestones.
Reduce job / negotiate part-time.
Kill or pause the business.

Do not allow a fifth option called “continue vaguely.”

That is how people lose years.

The founder lesson

Going all-in is powerful when the business has earned it.

It is dangerous when the founder uses it to escape discomfort.

The memo forces the difference.

If the evidence is strong, the constraint is real, the runway is responsible and the plan is focused, quitting may be the right move.

If not, keep building.

There is no shame in waiting.

Salary can be capital. Time can be bought with evidence. The leap does not need to come first.

The best go-all-in decision should feel scary.

But it should not feel unclear.
