What is a Sidecar Investment

If you're trying to understand what is a sidecar investment, you're looking for a clear answer — and how it actually plays out on your cap table, not just the general concept.

What This Actually Means for Your Cap Table

At its core, this touches on cliff period and vesting period. Most explanations stop at the general definition — this one is written for what happens to your ownership records next.

This is exactly the situation what is a sidecar investment comes up in for most founders.

Where This Fits on Your Cap Table

Cliff period and Vesting period both depend on the same underlying ownership data, so getting this right keeps your cap table accurate instead of quietly wrong. Lovie's cap table platform treats this as connected data, not a one-off calculation.

Most explanations of what is a sidecar investment stop at the general concept, not the cap table impact.

• Cliff period should be reviewed whenever your equity structure changes
• Vesting period changes the math for every existing stakeholder
• Most mistakes here come from tracking this in a spreadsheet instead of a live cap table

What is a sidecar investment is easiest to get right when it's tied to a live cap table, not a static example.

Frequently Asked Questions

What is a Sidecar Investment?

It depends on your specific situation, not a general rule — a sidecar investment is best checked against your actual cap table, not a static example.

• Confirm cliff period against your latest cap table, not an old spreadsheet
• Get any resulting change in writing before it affects a funding round
• Re-check this every time your equity structure changes

What should founders track on their cap table because of this?

Most founders get this wrong by treating it as a one-time task. It's worth revisiting every time you issue new equity, add a stakeholder, or close a round.

• Update your cap table the same day the change happens, not at quarter-end
• Loop in whoever else relies on the cap table — co-founders, investors, your accountant
• Keep a record of when and why the change happened, not just the new numbers
