How Long Does It Take to Raise Pre-Seed? A Realistic Timeline

A UK pre-seed round can take as little as two months or as long as six, and sometimes longer. For planning, budget three to six months from your first investor conversation to money in the bank. This guide covers what decides how long your round takes, the stages it goes through, what to have ready before you start, and how to keep it moving.

How long does it take to raise a pre-seed round?

Most UK pre-seed rounds take between two and six months. Some close faster, and plenty take longer. The safest assumption is three to six months, and you should plan your runway around that.

You don't always have to wait for the whole round to close before any money arrives. Angel investors can often commit and invest as you go, so you can start bringing cash in while you're still talking to other investors.

What decides how long it takes.

A few things make the biggest difference to how quickly a round comes together.

• The stage you raise at. This is the biggest one. If you've proven as much as you can before you start, have some real progress behind you and a clear story about why you need the money now, investors can say yes more quickly. Raise before you're ready and many investors will pass, which makes the whole round harder and slower.
• How compressed your round is. A round where you speak to lots of investors in a short window builds momentum. One that drifts across months loses it.
• How hard you go at it. Fundraising takes a lot of time and effort to get moving. The founders who treat it as their main job for those months close faster.
• The mix of investors. Angels can move quickly, often deciding in one or two meetings, and it's unusual for an angel to need more than three. Funds have their own process and diligence, which takes longer. We've seen sizeable rounds closed with angel money alone.

The stages of a pre-seed round.

Every round is different, but most follow a similar shape.

At pre-seed, the legals should be the easy part. When they drag, it's usually because something wasn't prepared earlier (see below).

What to have ready before you start.

Getting a fundraise running on all cylinders takes real time and effort, so do the groundwork before your first meeting.

• Your pitch deck. Writing a good one takes longer than most founders expect.
• Follow-up materials. A fundraising data room with the information investors ask for after a first meeting.
• Your target list. Which funds and angels you want to speak to, and how you'll reach each one.
• Your route in. Warm introductions where you can get them, and a plan for cold outreach where you can't.
• The start of a legal data room. It doesn't need to be finished before you raise, but start pulling together your legal documents, employment, customer and supplier contracts, details of your tech stack, and evidence that you own your IP and domains. See our guide to data rooms for fundraising and legal.
• A lawyer. Pick a commercial lawyer who understands venture deals before you start, not when the term sheet arrives.

What slows a round down.

Some delays are just the nature of fundraising. Many are in the founder's control.

• Relying on cold outreach. It works, but it takes longer. If most of your round is coming from cold approaches, allow more time.
• Losing momentum. Once conversations lose pace, everything starts to take longer, and investors' attention moves on to newer opportunities.
• No follow-up dates. Leaving a meeting without the next step booked is one of the easiest ways for a round to drift.
• Slow turnaround. Taking days to send documents or answers you promised slows everyone down.
• Information that isn't ready. Missing contracts, unclear IP ownership or scattered records hold things up at exactly the point you want to be closing.
• The wrong lawyer. A firm that doesn't know early-stage deals will slow the legals down. The fund's lawyers will know exactly what they're looking at, and your family's conveyancing firm that does the odd bit of corporate work is not the right fit.
• Messy structures. Unusual legal structures, debt that needs dealing with, or shareholders who need sorting out before the round (such as someone holding equity who is no longer involved) can all cause delays. Our guide to cap tables covers what investors look for.

How to keep pace and speed up your round.

The single biggest thing founders can do is keep pace. It's also the thing we most often see founders struggle with.

Investors are inundated with opportunities. When something new and interesting arrives, their attention moves to it. You have to keep your round moving to keep their interest.

• Treat it like a sales process. At the end of every call, book the next meeting or set a follow-up date, agree what each side needs to do, and send it over in writing.
• Turn things round quickly. If you've promised a document or an answer, send it fast.
• Learn each investor's process. Ask what they need to do before they can invest. If they need customer calls, line up customers who are happy to speak to them. If they take references, have your referees ready.
• Be ready to transact. The more you can say "we're ready to go", the faster things move.
• Don't wait to be led. Founders often assume the investor sets the pace. You have more influence over the speed of a round than you think.

It's a lot of work when you're speaking to many investors at once, but it's why fundraising takes so much time. Keeping pace is what gets rounds closed.

When to start raising.

Pre-seed is easiest to raise when it's about an opportunity, not about extending your runway. Many pre-seed startups can keep trading while they raise, and that puts them in a much stronger position.

The strongest story is a growth story: you've done something, you have early signal, and customers, or even potential customers, clearly want what you're building. You need the money to take that and move faster. That matters far more than any other part of the raise process. "We need cash to go and build something" is a much harder sell.

So start raising once you have that story, and with enough runway to cover a three to six month round without running short.

If your runway is tight

You can raise part of your round on an advance subscription agreement (ASA). Taking ASA commitments early gives you funding to start putting your plan into action while you close the full round. For more on timing your round, see our guide to pre-seed funding.
