In the imaginary Post Money Capital investment committee, the convertible note has one feature we particularly admire: a date. On that date, a founder who has spent two years avoiding a difficult conversation must have it with us. We consider this excellent scheduling software.
That is the fictional investor’s preference, not a recommendation for your company. Notes can be sensible instruments. They can also carry bargaining power that a discussion of the valuation cap never mentions. When someone tells you their preferred document is “basically the same as a SAFE,” ask which parts they would be happy to remove.
The calendar belongs to somebody
A convertible note is debt. It generally carries interest and a maturity date, with repayment, conversion and amendment mechanics specified in the agreement. A standard SAFE removes interest and maturity. That saves the founder from having to renegotiate a calendar while building the business. It also removes a pressure point the note investor might find useful. 13
Consider our fictional $500,000 note: 8% simple annual interest, twenty-four months to maturity. Two years later, the modeled balance is $580,000. That extra $80,000 might convert into shares or form part of a repayment claim, depending on the contract and the event. It is not money the investor has just wired to buy you another month.
Our hypothetical founder has spent the original cash hiring engineers. The noteholder has a claim. The engineers have salaries. Converting one into the other is an interesting legal problem and a poor payroll strategy.
Maturity does not mean every note automatically defaults, converts, or becomes immediately payable under identical rules. Read the actual notice requirements, holder elections, thresholds and extension provisions. Cooley’s Series Seed form gives you a useful structural reference; it does not make our imagined tough terms inevitable. 2
Leverage is not the same as recovery
The cynical reason to like a clock is that it can improve your negotiating position. A company nearing maturity may need consent to extend, convert or refinance. The investor can ask for a lower cap, extra protections or a different deal in return. Whether it can obtain those changes depends on the document, other holders and the founder’s alternatives.
The less cynical reason is that indefinite limbo genuinely exists. A company may never raise the priced round a SAFE investor expected. It can keep operating without producing an easy conversion or exit. A note can force the parties to confront that possibility rather than filing it under “next quarter.” 13
But a claim against a company with no distributable assets is not a cash machine. Debt priority can matter enormously when there is something to distribute. It cannot manufacture sale proceeds from a discontinued product and three office chairs. An investor who treats maturity as guaranteed repayment has misunderstood the collateral, especially where there is none.
The cap comparison everyone wants to skip
Suppose two offers both say $5 million. One uses a pre-money-style conversion denominator; the other is a post-money cap-only SAFE. You cannot compare them by pointing at the identical number. Which securities enter the capitalization? What happens when more convertibles arrive? Does accrued interest convert? Is there an option-pool increase? The denominator can be more expensive than the headline. 24
Likewise, “a cap and a discount” normally means competing conversion prices under the instrument’s specified rule, not a coupon automatically stacked on top of the cap. A negotiated note may depart from a familiar form. Familiar headings do not prohibit unfamiliar economics.
For a founder, the useful counterproposal is specific: enough maturity runway for the operating plan; a workable extension or conversion process; no invented sale windfall; and a capitalization model showing every outstanding instrument. For an investor, the legitimate question is what happens if the company never reaches the expected financing. Neither side needs to pretend the other has failed a character test.
What we would prefer you not to ask
In our fictional committee, we would enjoy keeping the conversation on the cap. It is an attractive number and looks excellent in an email. We would rather not spend the same afternoon explaining the amendment threshold, the repayment election and the effect of our sale premium on a small acquisition.
You should spend that afternoon there anyway. Ask who can change the instrument without your individual consent. Ask what the investor can demand at maturity. Ask how a weak sale would distribute actual cash, after creditors, rather than how much everyone “owns.”
A note may be the right financing for the circumstances. A SAFE may be. The investor’s enthusiasm for one is useful information about the investor. Read the date they are smiling at.
