Can we close a round in under 6 weeks?

Rare but possible — usually requires a hot company, warm relationship with the lead investor, and standard terms. Even then, legal close alone typically takes 3 weeks minimum.

How much runway should we have when starting?

9-12 months minimum. Below 9 months, investors sense pressure and use it in negotiation. Below 6 months, the range of acceptable outcomes narrows dramatically.

When should we start preparing?

3-4 months before you want money in the bank. Preparation is the phase most founders skip and most regret skipping.

Fundraising Timeline: Seed to Series C, Realistic Durations

Fundraising takes longer than founders expect. Here's the realistic timeline for each stage, what happens in each phase, and how to compress it.

Fundraising Timeline: How Long a Raise Actually Takes

Founders consistently underestimate fundraising duration by 40-60%. A "6-week raise" almost always takes 3-4 months when you count preparation, pipeline building, meetings, diligence, and legal close. Plan for the realistic timeline; anything shorter is a bonus.

Realistic durations by stage

Pre-seed (SAFE): 4-8 weeks preparation + 6-10 weeks active = 10-18 weeks total. Seed (priced): 6-8 weeks prep + 8-12 weeks active + 3-4 weeks legal = 17-24 weeks. Series A: 8-12 weeks prep + 10-16 weeks active + 4-6 weeks legal = 22-34 weeks. Series B/C: similar to A, slightly compressed by preparation from prior rounds.

Phases and what happens in each

Preparation: deck, data room, financial model, target list. Active pipeline: outreach, first meetings, partner meetings, diligence. Term sheet + legal: negotiation, financing docs, closing conditions. Every phase can compress if you're prepared; none can be eliminated.

What compresses the timeline

Warm intros to all first meetings (skips 2-3 weeks of cold outreach). Data room ready before first meetings (skips 2-4 weeks of scrambling). Financial model reviewed by finance-fluent advisor before sending. Multiple leads in play simultaneously (compresses negotiation from weeks to days).

What extends the timeline

Starting outreach before the deck is tight. Only one lead in play at a time. Diligence requests you can't answer quickly (customer references not warmed, financials incomplete). Bringing in existing investors late (they should be aligned before new investor conversations start).
