How Much Should You Raise? Work Backward From the Milestone

The raise amount is the result of the plan. Start with the milestone that changes your next financing conversation. Work backward to the money it takes to get there. Then add the time you need to prove it.

Most founders do it the other way around. They pick a number that feels reasonable, divide it by their burn and call the result runway. That number answers one question only: how long can we survive? Investors are asking a different question. What will this money make true?

I call the distance between those two numbers the Ask Gap: the gap between the amount that feels reasonable to raise and the amount your company actually needs to reach the next value-changing milestone.

Why a small ask can hurt you

A small ask feels safe. It sounds modest. It seems easier to fill.

Investors read it differently. A round that is too small for the milestone tells them one of three things. The founder has not costed the plan. The founder plans to keep a day job. Or the company will run out of cash before it creates enough new value to raise again. Each of those is a risk they now have to price.

A well sized ask does the opposite. It shows you know what the company must prove, what that proof costs and how long it takes.

A real case: from $500K to $1.2M

A founder I worked with recently was preparing a seed round in the UK. She planned to raise $500K. Her number came from runway and burn alone. When we went through the plan together, four problems showed up.

1. She had not paid herself to work full time. Her budget assumed she would keep splitting her attention. To an investor, a founder who is not in the business full time is an early warning sign.
2. There was no real milestone. The number described how many months she could operate. It did not describe what the company would have achieved at the end of those months.
3. Marketing was a flat line. She had spread the same monthly spend across every month. It read as a cost to be covered. It did not tell the story of an investment in growth with a clear return.
4. There was no view beyond the round. Nothing showed where this money would leave the company or what the next raise would look like.

We rebuilt the plan from the milestone backward. Full time founder salary went in. A one-time budget went in for the work the milestone required. Marketing became a staged plan that showed where spend increases and why. The ask rose to $1.2M.

The bigger number made more sense to investors because the rest of the pitch now supported it. A full time founder, a funded execution plan and a marketing budget that matches the growth story are easier to back than a lean plan that cannot reach its own goal.

I have seen the same pattern with founders of every gender. Underasking is a planning problem first.

The method in six steps

Step 1: Define the value inflection

Ask what must be true after this round for the company to be materially stronger. Repeatable enterprise sales in one market. A regulatory approval. A working product with a clear retention pattern. A channel that scales. A revenue level that changes the next conversation.

The right milestone depends on stage and business model. What matters is that it is specific enough to check.

Step 2: List the actions required

Turn the milestone into work. Hires, product development, sales capacity, pilots, certifications, market entry, partnerships, manufacturing. Write down what the company must do before you write down what it costs.

Step 3: Cost the full plan

Include everything needed to execute well. Founder compensation at a level that lets you work full time. Team. Tools. Sales and marketing. Professional fees. Sector specific costs.

Separate monthly costs from one-time costs. A certification, a launch or a key hire's recruiting fee is a one-time cost. Mixing them into monthly burn hides what the milestone really requires.

Step 4: Add time to prove the milestone

Reaching the milestone is half the job. You also need time to show the result before you raise again. I build in six months of cash after the milestone for the next raise. Hardware, biotech, regulated health and enterprise sales often need longer.

Step 5: Add contingency

Plans slip. Hiring takes longer. Sales cycles stretch. A buffer lets the plan absorb normal execution risk without forcing an emergency raise.

Step 6: Test the amount against investor logic

Check that the amount, the milestone and the stage fit together. If the milestone is too small, you raise again before you have created new value. If the plan is too broad, the ask looks unfocused.

The math, worked through

The formula I use:

Needed ask = monthly burn (including full time founder salary) × (months to milestone + 6) + one-time milestone costs

The six months are the time to prove the result and run the next raise. A contingency buffer goes on top.

The numbers below are an illustration only. They are rounded and do not describe any real company.

The milestone plan works out as $33K × 24 months + $150K = $942K. Add a 15% buffer and the ask is about $1.08M.

The $500K plan covers 20 months of the current burn and nothing else. No salary, no launch budget and no time to raise again. Its Ask Gap here is roughly $442K before buffer.

Check your own number

You can run this with your own figures in my free Ask calculator. It takes your burn, milestone timing and one-time costs and shows the gap between your planned ask and the amount the plan needs.

Five signs your ask is too small

• Your plan has no founder salary, or a salary nobody could live on.
• You can say how many months the money lasts but not what it achieves.
• Marketing is the same amount every month.
• The round ends the month you hit the milestone, with no time to show the result.
• Your use of funds slide is a pie chart with no milestone attached.

Common questions

How much should a seed startup raise?

Enough to reach the next value-changing milestone, prove it and raise again. Market ranges for your stage and sector are a useful sanity check. They should never be the starting point.

How many months of runway should a round cover?

Enough to reach the milestone plus time to show it and run the next raise. I use six months after the milestone as a minimum. Longer cycles need more.

Will a bigger ask scare investors away?

A bigger ask with no plan behind it will. A bigger ask where every slide supports the number reads as a founder who knows what her company needs.

Should founder salary be in the raise?

Yes. A plan that relies on an unpaid founder is a plan with a hidden risk, and investors will spot it.

Say it in one sentence

You should be able to say: "We are raising X to achieve Y. These three actions get us there. Reaching Y changes Z for the next round."

If that sentence is hard to finish, the round needs more work before it goes in front of investors.
