Caps and Discounts
A practical guide to caps and discounts for AI founders.
What This Lesson Covers
Caps and Discounts is a key topic in SAFE vs Priced Round. In this lesson you will learn the underlying principle, why it matters specifically for AI startups, the playbook experienced founders use, and the patterns to avoid. By the end you will be able to apply caps and discounts on your own startup with confidence.
This lesson belongs to the Fundraising category of the AI Startup track. AI startups succeed or fail on the same things every startup does — clarity of customer, defensible moat, focused execution — plus AI-specific dynamics around model dependency, talent wars, and rapid platform shifts.
Why It Matters
Choose between SAFE notes and priced rounds. Learn caps, discounts, MFN, post-money vs pre-money SAFEs, and when to convert.
The reason caps and discounts deserves dedicated attention is that the difference between an AI startup that becomes a category leader and one that gets stuck at $1M ARR usually comes down to a small number of decisions made early. Two teams with the same idea can end up in very different places based on how well they execute on this. The patterns below are taken from the founders who got there first — learning them does not guarantee the win, but skipping them almost guarantees a slower path.
How It Works in Practice
Below is a worked example of how to apply caps and discounts in a real AI startup context. Read it once, then sketch out how you would apply it to your own situation.
# SAFE primer for AI founders
SAFE_TYPES = {
"post_money_safe": (
"Today's standard. Cap is post-money, so dilution is predictable. "
"Use this unless an investor insists otherwise."
),
"pre_money_safe": "Older form. Dilution math is harder. Avoid.",
"uncapped_mfn": "Investor gets the best terms of the next priced round (or cap).",
}
# Rule of thumb
SAFE_TIPS = [
"Use ONE SAFE template for ALL pre-seed checks (Y Combinator post-money SAFE)",
"Use the SAME cap for all SAFEs in the same round (avoid drama later)",
"Track total dilution across all open SAFEs - it adds up faster than you think",
"Switch to a priced round when raising > $3M or when an investor insists on a board seat",
]
# Quick conversion math
def safe_dilution(amount: float, cap: float) -> float:
return amount / cap
print(f"$1M on $10M cap = {safe_dilution(1e6, 10e6):.1%}")
Step-by-Step Walkthrough
- Anchor on a real-world example — Pick one AI startup whose execution of caps and discounts you admire. Study what they did and the trade-offs they accepted.
- Define your inputs — Get the data, customers, dollars, or commitments you need before deciding. Decisions made without inputs are guesses.
- Pick the smallest reversible step — Most decisions can be tested before being committed. Find the cheapest test that produces real signal.
- Set a kill criterion in advance — Decide what would tell you to stop, BEFORE you start. Without it, sunk-cost fallacy will keep you in.
- Communicate the decision and reasoning — Write it down. Future-you and future hires will need to know what you decided and why — not just what you did.
When To Use It (and When Not To)
Caps and Discounts is the right move when:
- The decision is non-trivial AND the consequences will compound
- You have enough data (customer signal, financial information, team feedback) to decide responsibly
- You can commit the team and capital required to execute
- The risk of inaction is greater than the risk of moving forward
It is the wrong move when:
- A simpler, cheaper decision would meet the need
- You do not yet have the inputs needed to decide responsibly
- The decision can be deferred until you have more signal
- You are still iterating on the underlying strategy — commit to the strategy first
Founder Checklist
- Have you reduced the decision to one sentence you could explain to a non-founder?
- Do you know the cost of being wrong (in dollars, time, talent, market position)?
- Have you discussed the decision with a peer founder, an advisor, OR a coach?
- Have you written down the decision and the reasoning so you can revisit it in 90 days?
- Have you set a kill criterion you can recognize without ego getting in the way?
- Are the team members affected aware of the decision and the why?
Next Steps
The other lessons in SAFE vs Priced Round build directly on this one. Once you are comfortable with caps and discounts, the natural next step is to apply the patterns from the surrounding lessons — that is where compound returns kick in. Startup decisions are most useful as a system, not as isolated tactics.
