Guide

A term sheet is usually non-binding on economics (except no-shop and confidentiality). Closing a priced round means converting that sheet into definitive documents. Lawyers on both sides negotiate against NVCA model forms. A clean Series A with one lead often closes in 4–8 weeks from signed term sheet; multi-party rounds and messy cap tables take longer. Budget legal fees in the tens to low hundreds of thousands of dollars depending on complexity — paid by the company from the round proceeds.

The big idea

The term sheet is the sketch. The closing binder is the building. If a right is not in the charter or a signed agreement, it is not a right.

Walking through close mechanics

Multiple closings are common: the lead closes first (initial closing), and other investors join within a window (e.g. 60–90 days) at the same price. The certificate authorizes the full series; shares are issued as checks clear. Model the cap table at full close, not just first close, when you talk about ownership.

Converting outstanding SAFEs and notes usually happens at the same closing: those investors become preferred (or a separate series) based on their caps and discounts, and their shares count in the pre-money fully diluted total. Get that conversion schedule right before you celebrate the headline valuation.

Not every first priced round is a Series A. Many companies raise a priced seed: smaller check ($1–4M as of typical mid-2020s ranges, though the band moves), simpler docs, sometimes a smaller board ask. Same machine — preferred, pre/post, pool, price per share — less ceremony. Use it when a lead wants ownership clarity and a board seat. Stay on SAFEs when you need speed, many small checks, and are not ready to set a price.

Before you sign, build four columns: pre-round, after SAFE/note conversion, after pool top-up, after new money. If that sheet does not match the term sheet's ownership paragraph in ten minutes, you do not understand the deal yet.

As an engineer, ask last preferred price, current 409A, leftover pool, whether preferred is 1× non-participating, and what % of FD your role's grant is. Those beat any "competitive package" adjective.

Common mistakes

  • Modeling only the first close and ignoring the $500k that might join in 45 days.
  • Celebrating headline valuation before SAFE conversion is on the table.
  • Assuming seed priced docs are "Series A lite" without reading the veto list. Sometimes they are; sometimes they are not.

Check yourself

How long is a clean one-lead Series A from signed term sheet to close, typically?

About 4–8 weeks.

Why model the cap table at full close, not initial close?

Later closings issue more of the same series at the same price; ownership at first close is incomplete.

Key takeaways

  • Closing means charter + SPA + rights agreements, usually on NVCA-shaped forms.
  • Multiple closings are normal — model the full round.
  • SAFEs and notes convert at the priced close; put them in the denominator.
  • A priced seed is the same machine with less ceremony.
