You have no leverage in a fundraise until you have a term sheet. The moment you have one, you have all of it. 

Everything before that first signed offer is grind; everything after is negotiation. Understanding how to use that moment, and what to check before you sign, determines whether the round closes well or closes at all.

What changes when you get your first term sheet?

Everything. The first term sheet typically lands around week three of a compressed raise. As soon as it does, email every investor still in your process: we have a term sheet and will be selecting an investor by the end of the week. You don't name the fund. You don't need to. One credible offer converts hesitation into fear of missing out. If one investor has conviction, the others suddenly need a reason not to.

Before that point, artificial deadlines don't work; investors know the game. After it, the deadline is real, and enforcing it is how you stack multiple offers into the same window.

Should you choose the highest valuation term sheet?

No. Choose the partner. 

Founders with multiple term sheets routinely take a lower valuation to work with a specific individual, then use the competing offers to negotiate that investor's terms upward. An extra million on the headline number, or half a point of dilution, is worth far less than a partner who backs you when things go wrong and things will go wrong.

A critical distinction: you take money from a fund, but your relationship is with a partner. The same firm can contain both the most supportive investor you'll ever have and someone with a track record of firing founders and backing competitors. Reference-check the individual with founders in their portfolio, not just the brand on the letterhead.

What term sheet clauses should founders watch for?

Term sheets are signed under time pressure, and the dangerous clauses are the ones that look boilerplate:

• Founder leaver provisions:  Badly drafted good/bad leaver terms can strip your equity on exit from the business.

• Minority veto rights: Small investors with blocking rights over key decisions can paralyse or effectively seize control of a company. These clauses have quietly killed European startups.

• Non-standard drafting - Watch out for overly complex legalese. Insist on plain-English, market-standard documents.

The practical answer: Term sheets carry short signing windows and you (insert Claude) won't spot the tricks yourself.

Should you put your valuation in the pitch deck?

It depends, but try not to. 

Valuation is an output of the process, not an input. It's set by supply and demand across your term sheets, like a share price. If asked directly, answer in dilution terms: "we're raising £X and expect to give away 10–20% including the option pool." Investors think in ownership percentages anyway.

On the raise amount itself, go out with the lower end of your range and get pulled upward. Telling the market you're raising £4–5m and closing £6m reads as momentum. Announcing £7–9m and closing £5m reads as a struggling round, even if the cash raised is identical.

Two closing rules

• Don't take money from friends and family unless you truly have no alternative. Every dinner becomes a shareholder meeting, in good times and bad.

• Send updates sparingly. Detailed company updates circulate beyond your cap table. Keep wide distribution high-level; reserve the real numbers for your largest investors.
