Practice Notes: When a Family Office Writes a Startup Check, the Paper Looks Different

We’ve represented founders taking checks from family offices and we’ve represented family offices writing checks into startups. The paper that gets signed in those rounds looks different from a standard VC round, and the differences cost founders money if they aren’t flagged early.

The pattern

A family office is a private wealth structure managing capital for a family or a small group of related parties. When that office invests in a startup, the office is usually thinking about: (1) the tax position of the family, often involving trusts, grantor-trust mechanics, and estate planning; (2) downside protection because the office is not in the business of taking thousand-portfolio bets; (3) information rights tailored to the office’s reporting cadence with the family.

What we typically see in the side letter

  • Customized information rights. Quarterly financials, an annual audit, and sometimes a customized capitalization-table reporting cadence the family office can plug into its internal portfolio management.
  • Pro rata participation in all future rounds, often paired with an MFN clause covering economic terms.
  • QSBS-friendly structuring when the family expects to hold the position long enough to qualify for IRC § 1202 treatment. The investment vehicle (LLC, trust, or individual capacity) matters for QSBS eligibility.
  • Pre-emptive consent rights on a narrow list of governance actions — typically secondary sales by the founder, related-party transactions, and significant departures from the business plan.
  • Restrictive transfer covenants on the office’s side. The office often wants the right to transfer the position internally among family-controlled vehicles without the company’s consent, which the company’s standard form usually does not allow.

Where the friction shows up

Founders often treat a family-office check like a VC check and run the same paper. Then the family office’s lawyer marks it up heavily and the negotiation eats more time than the check size warrants. Better to recognize early that the office’s investment committee thinks about risk differently than a venture fund, and to scope the side letter at the term-sheet stage rather than discovering the office’s needs in the long-form documents.

The QSBS issue is the most consequential

If the family wants their position to qualify for QSBS treatment on the exit, the investment has to be made in a way that satisfies § 1202’s eligibility requirements. Some family offices invest through a partnership or LLC that the IRS will look through for QSBS purposes; others invest through trusts where the analysis is more involved. We coordinate with the family’s tax advisor before the closing — it’s much harder to retrofit QSBS eligibility after the round is funded.

What we tell founders

If your investor is a family office, ask the office’s lawyer up front what they need that a standard SAFE plus side letter won’t deliver. Map the differences in the term sheet. Accommodate the ones that are about tax and reporting; push back on the ones that are about governance veto rights.
