Because apparently, we no longer sell things. We optimize CAC, track LTV, expand TAM, and raise a bridge while extending the last round that was not really a round. Breathe.
Here is the simple version, with jokes and no fluff.
Quick wins to keep in your head
CAC: what it costs to get one paying customer
LTV: how much money you will make from that customer over time
Burn rate: how much cash you spend each month
Runway: months of life left at your current burn
Churn: how many customers leave
Payback period: how long it takes to earn back your CAC
If you can explain those six in simple English, you can survive most meetings.
Market size trio: TAM, SAM, SOM
TAM, Total Addressable Market: everyone on earth who could use your thing if the stars aligned. Dream land.
SAM, Serviceable Addressable Market: people you can actually reach with your product and channels.
SOM, Serviceable Obtainable Market: what you can realistically win in the next few years once reality shows up.Joke to remember it: TAM is the universe, SAM is your country, SOM is your neighborhood.
Customer money talk
CAC, Customer Acquisition Cost: total sales and marketing spend divided by new customers. If you spent 1,000 and got 10 customers, CAC is 100.
LTV, Lifetime Value: average revenue per customer times how long they stay, adjusted for margins.
LTV to CAC ratio: a quick sanity check. Many folks aim for about 3 to 1 or better.
Payback period: months to recover CAC from gross profit. Shorter is better.
ARPU or ARPPU: average revenue per user or per paying user.
Churn: customers who leave. Logo churn counts accounts. Revenue churn counts dollars.
Retention: the opposite of churn. If people stay, the product is doing real work.
Cohorts: groups of users who started in the same month. Watch how they behave over time to see real retention.
Revenue words that cause arguments
MRR and ARR: monthly and annual recurring revenue.
Gross margin: revenue minus cost to deliver. High margin gives you room to grow.
Contribution margin: gross margin after variable costs like support or payment fees.
GMV: total transaction value in a marketplace. Not the same as your revenue.
Take rate: your slice of GMV. If GMV is 100 and you take 10, revenue is 10.
Rule of 40: growth rate plus profit margin around forty is considered healthy. Loose rule, not a law of nature.
Product fit and growth
MVP, Minimum Viable Product: the smallest thing that proves value. Ugly is fine if it works.
Prototype: a quick model to test an idea.
Proof of concept: a small experiment to show it can work at all.
Product market fit: users pull the product from your hands, you keep up rather than push.
North star metric: one number that shows delivered value. Pick something users feel, not just clicks.
DAU, WAU, MAU: daily, weekly, monthly active users. Useful only if you define active with care.
Stickiness: DAU divided by MAU. A rough feel for habit.
K factor: virality. Over 1 means each user brings more than one new user. Rare, do not bank on it.
Vanity metrics
Pretty numbers that do not pay rent. Impressions, views, sign ups that never activate, likes from bots. If the number does not tie to revenue, retention, or clear progress to either, it is probably vanity.
Business model basics
Business model: how you make money, who pays, and why they keep paying.
Business Model Canvas: nine boxes on one page to outline customers, value, channels, and money.
Business plan: longer document with research, risks, and financials. Often useful for banks and grants.
Use the canvas to think, use a plan when someone formal asks for it.
Fundraising levels in plain English
Idea or friends and family: people who love you more than they love due diligence.
Pre seed: very early belief money to find fit.
Seed: money to prove repeatable growth, not just a lucky month.
Series A: scale what already works.
Series B and later: bigger checks for bigger growth and bigger expectations.
Bridge or extension: extra money between rounds.
Down round: new valuation is lower than last time. Painful but survivable.
Secondary: investors buy shares from existing holders. No new cash into the company.
Fundraising instruments
SAFE: a simple agreement for future equity. Usually includes a valuation cap, sometimes a discount. Converts into shares later.
Convertible note: a loan that converts to equity later, usually with interest.
Priced equity round: you sell shares at a set valuation now.Important words here:
Valuation cap: the highest valuation used for your SAFE at conversion.
Discount: a percent off the next round price.
Most favored nation: if later investors get better terms, early ones can match.
Pro rata rights: the right to invest more later to keep the same ownership.
Term sheet words you will hear
Liquidation preference: who gets paid first in a sale. One times non participating is common. Participating means they get money back and share in the rest too.
Anti dilution: protects investors if a later round is cheaper. Weighted average is common.
Board seat and observer: who gets a vote, who just listens.
Protective provisions: things you cannot do without investor approval.
Read this stuff slowly and ask questions. Boring saves lives.
Cap table and options
Cap table: the spreadsheet of who owns what. Treat it like a sacred text.
Option pool: shares reserved for future hires. Often expanded just before a round.
ESOP: employee stock option plan.
Vesting: shares earned over time, for example four years with a one year cliff.
409A: a valuation for pricing options in the United States. Your local rules may vary.
Money health
Burn rate: how much cash you spend per month.
Runway: cash on hand divided by burn. Twelve months is a comfy pillow.
Burn multiple: net burn divided by net new ARR. Lower means you are efficient.
Sales efficiency or magic number: how much revenue next quarter you get from sales and marketing this quarter. A simple sniff test for go to market spend.
Go to market words that show up on slides
ICP, Ideal Customer Profile: the kind of customer who gets the most value and will actually buy.
Buyer persona: the human inside that company who signs or champions the deal.
Funnel: awareness, interest, decision, purchase, then expansion.
Conversion rate: percent of people who move to the next step.
A B testing: try two versions, keep the one that wins.
OKRs and KPIs: goals and the numbers that prove they happened. Keep them few and boring.
Moat and defensibility
Investors will ask what protects you once people notice you. Real moats look like this:
Network effects, the product gets better as more people use it
High switching costs, moving away is painful or slow
Proprietary data, you have unique information that improves results
Scale benefits, bigger is cheaper in a way that matters
Brand and trust, hard to copy but very realMagic words without proof are not a moat.
Screenshots are not a moat. A good sleep schedule is not a moat, though it helps.
