talk the talk (a tech glossary)

tl;dr: learn the language of tech niches

read time: 10m (skim), closer to an hour top to bottom

Below is a condensed glossary from my time working in early stage VC, growth, and software engineering.

It is designed to approachable for everyone, especially those without a prior background in the subject area.

For acronyms, I will list the more commonly used of the full phrase or acronym first (e.g. SEO is said more commonly than Search Engine Optimization)

I will continue to add to this list over time. Feel very free to email me ( your suggestions of phrases to add or definitions to update.

If you end up recycling part of this for your corporate blog/onboarding, please throw in a rel=follow backlink 🙃

table of contents:

startups - general

Unicorn: A company worth over $1B. full list here. 'Unicorn' usually also implies the company is private (i.e. not IPO’d/acquired)

EOD/EOW: End of Day/Week (similar to COB/Close of Business)

USP (Unique Selling Points/Propositions): The specific benefits that make you/your business special!

MVP (Minimum Viable Product): The fast, crappy product you throw together to see if anyone will buy it. Make this to test if the market actually wants your thing. Better to make something flawed but useful than perfect but nobody needs it

KPI (Key Performance Indicator): The metrics that actually matter to a given business (e.g. DAU/MAU ratio for a consumer social app)

OKR (Objectives, Key Results): Action-focused goals; how big companies allocate resources and evaluate results. Related to, but different from, KPIs

NPS (Net Promoter Score): On a scale from 1-10, what score do people give a product or service? More here
The formula is [# of 9's and 10's] minus [# of 1-6's].

ARR (Annual Recurring Revenue): The revenue per year you’d make if you didn’t acquire or lose any customers.
The formula is [this month's recurring revenue] * 12

🚨 potentially confusing: If a given business's revenue does not reoccur (i.e. is not a subscription), *you should not call it ARR*. The phrase Annual RUN RATE has the same acronym, but ARR is never used to mean that. Intentionally conflating this is misleading and will cost you credibility.

MRR (Monthly Recurring Revenue): A given month's (generally, the current month's) recurring revenue.

UX (User Experience): How people use and interact with a product/service. There are many viable UX modalities; it is up to you to figure out the ones most accessible to your users.

UI (User Interface): What people see and click on. This can be a website, a mobile app, a chatbot, an SMS interaction, code, or many other things

API: Application Program Interface – A technical framework for exchanging data. Many, many parts of society rely heavily on APIs to communicate data. More here

Inbound: Business interest that comes in - e.g. cold emails to you, submitted forms on your website, etc

Outbound: Business interest you generate by reaching out - e.g. cold emails you sent, connecting to a lead via LinkedIn, meetings you ask for

Vertical: For a specific field (e.g. a vertical social network like Spiceworks allows individuals in that field to interact with just each other). Loosely related to vertical integration, which is owning more parts of your supply chain

Horizontal: For a specific offering or market opportunity (e.g. Dropbox is usable by anyone). Horizontal integration is usually called monopoly

Siloed: when data/personnel/information is separated from relevant resources/teams. There are great career opportunities if you can effectively streamline/connect people/data

Retention: A company’s ability to keep a customer loyal to their product or service.

Churn: Customers that leave in a given period of time. This may refer to Dollar Churn (how much revenue worth of cancellations happened) or Logo Churn (the number of companies that cancelled)

Upsell: A customer upgrading their purchase (e.g. to a higher tier or more subscription seats). Increasing upsell (and decreasing downgrades) is a big part of growing a startup successfully

Cross-sell: A customer who has already bought Thing A later buying Thing B, C, or D. Sometimes cross-sell is during the original purchase, sometimes it's later (e.g. via a series of emails)

Turnkey: A product or service that operates with easy onboarding and UX

White Label: A product or infrastructure is sold to companies with the understanding that they will present and brand it as their own; an example is landing page builders like Instapage

Unit Economics: The marginal revenue and costs associated with selling one item, not in consideration of larger expenses like R&D and general staffing

Contribution Margin: The incremental profit earned on each sale (price minus all variable costs). A negative contribution margin business will most likely fail

Audience Turnover: The part of an audience that changes over time. An example being: teens have high audience turnover because every year 1/5th of the audience ‘graduates’ out

Cohort: A qualitatively defined group of users with a set of common characteristics you can define. For example, a cohort of Male 13-17 users who signed up in January 2019

A/B Testing: Comparing two versions of some content to determine which would perform best. For example: changing the wording of an email, or the images on a website and comparing which versions perform best. The typical statistical benchmarks are 0.05 for alpha (95% confidence the result was not due to chance) and 0.8 for power

Marginal: the costs/benefits associated with one “extra” event (eg acquired customer). The economics of marginal events (e.g. to cost to acquire a marginal customer) are core to a business's success or failure

Giveaway: A free offer OR a broadcast program that offers free gifts as prizes

K factor: the number of users a given user refers. A K Factor > 1 indicates a truly viral product that will grow exponentially

Ad poaching: where different ad set are competing for the same impressions. At best it muddies analysis, at worse it worsens performance. More here

A18+: Audience of 18+ year old adults

IO (Insertion Order): A way to pay for ads. Similar to a line of credit where you only pay for what you use. A fallback if you aren’t approved in a credit check for a platform. Includes the copy and specs necessary to run ads.

Dayparting: Changing the bidding environment at specific segments of the day in order to take advantage of consumer buying preferences. An example would be increasing bids in the early morning, as there are fewer advertisers targeting that time.

marketing channels

Paid Social: Facebook, Instagram, Youtube, Snapchat, Pinterest, Twitter, etc

SEM (Search Engine Marketing): Paid user acquisition via search (e.g. Google, Bing, DuckDuckGo). This is different than SEO (see more below)

Branded Search: any search keywords that include references to the brand (e.g. “Intercom chat"). These tend to be people who already intend to buy, so the CAC is very cheap.

NonBrand (NB) Search: All search keywords that are not branded search (e.g. “chat application”). These tend to be people who have some intention to buy, but may comparison shop, so the CAC can be expensive.

SEO (Search Engine Optimization): The practice of designing web pages so that they rank as high as possible in the search results from search engines.

Ad Network: Ad networks (advertising network, banner network, online ad network) are advertising companies which administer ad sales for a collection of websites. Ad networks often aggregate sites into specific categories or demographic groups, then sell ad inventory to advertisers. Ad networks can sell ad inventory on CPM, CPC, CPA and other revenue models. There is lots of fraud in ad networks

Affiliate Marketing: A type of performance-based marketing in which a business rewards one or more affiliates for each visitor or customer brought by the affiliate’s own marketing efforts.

Affiliate Network: Acts as an intermediary between publishers (affiliates) and merchant affiliate programs.

Out of Home (OOH): Any physical media that is outside the home. Example being: on the side of buses, on bus stops, on posters, etc.

Direct Mail Advertising: Advertising sent by physical postal mail. Direct Mail is especially good for advertising to homeowners/renters

marketing - metrics

CAC (Cost of Acquiring a Customer): The fully loaded cost of getting one marginal customer. This generally does not include COGS

CPA (Cost Per Action): Generally this means cost of acquiring a customer, though it also can mean any other action (e.g. a trial signup)

CVR (Conversion Rate): The proportion of visitors to a website who make a purchase, usually calculated as a percentage of Purchases/Clicks

CPM (Cost Per Thousand Impressions): The dollar cost of advertising exposure thousand times (not that this is not necessarily 1000 unique individuals). It is a useful dollar comparison that shows the relative cost of various media. CAC correlates with CPMs.

CPC (Cost Per Click): Relatively self explanatory. Search advertising (Google, Amazon, Bing) tends to bill on CPC

CPA billing: Some ad networks (and most affiliate networks) will charge per agreed upon event (like a sale). Be sure to do your diligence and ensure the action they are supplying is not fradulently completed

Impressions: The number of times a person saw your ad. Not the same as the number of people who saw it (that's usually called Reach). Never optimize for impressions

Add-To-Cart (ATC): The act of clicking to add an item to an online shopping cart. If you don't have many purchases (e.g. your adspend is low), you can optimize for add-to-carts instead; be aware that it is less ideal and bots will inflate your ATC numbers.

Engagement Rate: A metric that measures the level at which people are interacting with content including comments, likes, shares, etc.

Relevancy: An ad platform’s calculation of how relevant your ad is to your target customers. This may correlate more or less tightly with CAC.

Position: The location of an advertisement on a page (particularly search). 1st position is at the top.

ViewThrough: A customer that looks at (has an Impression) on a display ad, but does not click through. They later convert, and are attributed back to the original source. More here

Attribution/LookBack/Conversion Window: Time when an ad server will take credit for a customer conversion. Usually 1 day view / 7 day click

Evergreen: Ad sets/campaigns that perform consistently well over time

DR (Direct Response): an acquisition funnel that goes directly to purchase. This is the opposite of Brand Marketing

Pre-Roll Ads: Video ads that play before the beginning of web video content

Interstitial Ad: Interstitial advertisements are usually full-page popup ads displayed while a user is navigating from one page to another

Native Advertising: A type of advertising that matches the form of the platform on which it appears. e.g. hiring Buzzfeed to write a listicle about your business (e.g. Taboola and Outbrain facilitate native ads)

Rich Media: Rich media advertisements are banners (or popups, skyscrapers, interstitials, etc.) which are constructed using dynamic tools such as Flash, HTML forms, Java, ASP, Shockwave, Javascript. These are by my understanding being phased out, in part due to the use of adblockers

UGC (User Generated Content): Content that has been produced by customers, clients, or consumers.

ROS (Run Of Site): Placement option that targets all pages of a given website. This tends to be broadly targeted and the cheapest option of display ads

Remnant: Ad inventory that is 'left over' (the timeslot is sooner and the seller has yet to find a buyer). Remnant exists on TV, programmatic, and display, and is typically relatively cheaper than comparable 'regular' inventory

marketing - specific ad channels

Skagging: Creating Single Keyword Ad Groups (or SKAGs). There are pro's and con's to this.

URL Masking: Redirecting a user to a different site after they hit the landing page, rather than being able to purchase there. Google hates this!

First Price + Second Price: An ad bidding mechanism - more here

Bid Shading: Trying to predict historical bid data to lower bids to the minimum required to win the auction. Only makes sense in first price platforms. Vendors frequently charge by a % of difference between intended and eventual bids.


Featured Videos: A section of YouTube which displays particularly popular or Partner videos.

TrueView Video Ads: Skippable ads you only pay for when viewers watch or interact with your video.

TrueView In-Stream Ads: Ads that play your video before, during, or after other YouTube videos.

TrueView Discovery Ads: Ads that are displayed as a thumbnail and are used to promote your content in places of discovery (i.e., YouTube mobile homepage, in YouTube search results, or next to related YouTube videos).

Bumper Ads: Unskippable videos up to six seconds long that play before, during, or after a user watches the main video.


Carousel: Features two or more scrollable images or videos.

Slideshow: Features a looping video with up to 10 images.

Broad: Broad targeting is effectively showing ads to the largest possible group of people and trusting the ad platform to optimize without restrictions

Interest: Interest targeting shows ads to individuals who have directly or indirectly shown interest in a given topic

LAL/LLA (Look Alike Audience): A targeting option that ingests a list (of customers or website viewers, or some other attribute) and the ad platform finds people who are similar. A 1% Lookalike audience targets the 1% of (e.g.) Facebook's users that are the most similar to the provided 'seed' list

DABA (Dynamic Ads to Broad Audiences): A targeting option that ingests a catalog of your products and will dynamically show ads of those products to all Facebook users. Over time, FB's bidding will optimize for those most likely to buy. DABA is ideal for eCom stores with a number of SKUs but little existing advertising data More here

CAPI (Conversions API) (fka Server-To-Server API): A technical option to send conversion data to Facebook from a server you control, rather than from the client-facing website. This avoids problems with adblockers and cookies, but requires substantially more setup

Offline Conversions API: An API that is similar to - but not the same as - CAPI, specifically for tracking and optimizing events at physical retail stores


Display: A closed network through which an advertiser can buy ads that are served on various locations on various websites (e.g. on news websites). Display can be difficult to attribute and difficult to scale. Beware of display fraud

Programmatic: Programmatic sits on top of display & ad networks; ad inventory is bought through multiple exchanges, rather than one closed exchange. More here

RTB (Real Time Bidding): A way for ad exchanges and DSPs to dynamically price ad inventory to be sold. More here

DSP (Demand Side Platform): A platform through which advertisers can buy display inventory across many websites. Similar to ad exchanges. DSPs use RTB. More here

SSP (Supply Side Platform): A platform through which publishers (websites like blogs and new sites) make their ad inventory (spaces on their website for a given period of time) available to advertisers

PMP (Private Marketplace): A closed platform with one publisher and a smaller number of advertisers. PMP publishers may have higher quality ad inventory (hence the ability to market it privately)

Ad Exchange/Network: Both Exchanges group and filter ad inventory. Exchanges then make the inventory available to buy, while Networks pre-purchase and mark up the ad inventory), but some folks will use the terms interchangeably. More here

websites - landing pages

Landing Page: A landing page is a webpage to which a user is directed after clicking an ad. For Direct Response Marketing, it is important that the landing page is one which entices users to immediately purchase a product or service (in contrast to the home page, which is more informational)

Call to Action (CTA): A piece of content intended to induce a viewer, reader, or listener to perform a specific act, typically taking the form of an instruction or directive (e.g. buy now or click here ). Informally, a button or interaction that moves a user down an acquisition funnel may also be called a CTA.

Above the Fold:Generally refers to anywhere on a web page that can be viewed without scrolling either horizontally or vertically. Most online ad networks define suitable above the fold placement as within 500 or 600 pixels of the top of the page. A significant portion of visitors to a website will leave before scrolling below the fold.

Bounce Rate: The percentage of visitors to a particular website who navigate away from the site after viewing only one page.

Backlink: a link from some other website (the referrer) to that web resource (the referent). A web resource may be (for example) a website, web page, or web directory. The value of these is highly dependent on if they are rel=follow or not

SERP - Search Engine Results Page: The results page of a search (usually Google). How a website is portrayed in the SERP can affect traffic and conversion rates

Average Page Depth/Scroll Depth: How far down a given page an average user scrolls. For example, an average person scrolled 23% of the vertical height of a webpage. If 3/4 people don't make it to the conclusion of an article, it matters a lot less how eloquent it is

Pages Per Session: The average number of pages on a site that a visitor views during a single session. A high PPS can be good (highly engaged readers) or bad (people click but don't buy), depending on your type of business

Cookie: A way to track a user and customize their website experience. Cookies allow you to show an existing user a logged-in page, for example.

Mobile Optimization: The process of ensuring that visitors who access your site from mobile devices have an experience optimized for their device. Check your Google Analytics - the % of traffic from mobile is probably much higher than you think!

Uniques (usually refers to Unique Visitors): The number of distinct individuals who take an action in a given time period, as determined by IP address, user login, cookie, or some combination thereof

websites - CRO

CRO (Conversion Rate Optimization): A system for increasing the percentage of visitors to a website that convert into customers, or more generally, take any desired action on a webpage.

ASO (App Store Optimization): Like SEO, but for Apple's and Google's App Stores. This isn't technically CRO but has similarities.
