How to raise a seed round

The dealOS Team 9 min read

Raising a seed round is a sales process with one product, your company, and a small, researchable market of buyers. Founders who treat it that way close faster and on better terms than founders who improvise. This guide walks through the process end to end: sizing the round, preparing materials, building the investor list, running meetings in waves, and closing.

1. Decide how much you are raising, and why

Investors fund milestones, not months. Start from the story you want to tell at your next round: the revenue, product or usage proof that makes a Series A obvious. Cost that plan, add a buffer, and you have your raise. For most companies that means eighteen to twenty-four months of runway.

Anchor the number before your first meeting. "We are raising £1.5M to get from £20k to £100k MRR and launch the self-serve product" is a plan. "We are raising £1M to £3M depending on interest" is an invitation to negotiate against yourself.

2. Prepare the three materials that matter

You need exactly three things before you approach anyone:

Keep the numbers identical across all three. Inconsistent figures between deck, teaser and model are the most common diligence red flag, and entirely avoidable.

3. Build a researched investor list

The single biggest time-waster in seed fundraising is meeting investors who were never going to invest: wrong stage, wrong sector, wrong geography or wrong cheque size. Every hour spent qualifying the list saves several hours of dead meetings.

Qualify on four dimensions: stage (do they actually lead or follow at seed?), sector (have they backed companies like yours?), geography (do they invest where you are incorporated?), and ticket size (does your round fit their model?). A researched list of one hundred to two hundred investors who pass all four filters beats a list of five hundred names from a directory. This is precisely the work investor matching software compresses from weeks to minutes.

4. Run the process in waves, not dribbles

Approach investors in batches of fifteen to twenty-five, starting with a practice wave of firms you would accept but not prefer. You will hear the same three objections in your first ten meetings; fix the pitch, then approach your preferred investors with the sharpened version.

Momentum is the currency of a raise. Investors move when other investors are moving, so compress meetings into a tight window rather than spreading them across a quarter. Track every conversation: who has the teaser, who viewed it, who asked for the deck, who went quiet. A fundraising pipeline tracker keeps that picture live so your follow-ups are driven by engagement, not memory.

5. From term sheet to close

A term sheet is the beginning of the end, not the end. Keep other conversations warm until the money is in the bank: deals fall over in confirmatory diligence more often than founders expect. Respond to document requests within a day, keep your data room current, and resist renegotiating small points that cost goodwill.

When the round closes, tell everyone who took a meeting. The investors who passed this time are the warm top of your Series A list.

The short version

Size the round from milestones. Prepare a deck, a teaser and a data room with identical numbers. Build a qualified list, approach it in waves, track every conversation, and keep momentum through diligence. Fundraising rewards process, and the process is entirely learnable.

Frequently asked questions

How long does a seed round take?

Plan for three to six months end to end: four to six weeks of preparation, six to ten weeks of active meetings, and four to eight weeks from term sheet to money in the bank. Founders who treat it as a structured process sit at the short end of that range.

How much should I raise at seed?

Enough to reach the milestones that unlock your next round with a buffer, typically eighteen to twenty-four months of runway. Work backwards from the Series A story you want to tell, not forwards from a valuation you would like.

How many investors should I approach?

More than feels comfortable. Conversion from first meeting to term sheet is routinely under five percent, so a serious seed process usually means a researched list of one hundred to two hundred relevant investors, approached in waves.
