Instacart

Uber

Uber is a marketplace that connects riders with drivers. You request a ride through the app, the nearest driver accepts, picks you up, drops you off, and Uber takes a cut — typically 25-30% of the fare.

The driver keeps the rest. Uber doesn't own any cars.

They don't employ any drivers. They built a $150 billion company by being the middleman with a really good app.

The model expanded into Uber Eats (food delivery, same concept — restaurants cook, drivers deliver, Uber takes a cut), Uber Freight (connecting truckers with shippers), and advertising. The advertising business is quietly enormous — Uber has data on where millions of people go every day, and brands will pay handsomely for that.

Instacart

Instacart operates as a marketplace connecting consumers with personal shoppers and grocery retailers. Revenue comes from multiple streams: delivery fees and service fees charged to consumers (typically $3.99+ per delivery), tips to shoppers (passed through, not revenue), retailer partnerships (grocers pay Instacart for access to the platform and fulfillment services), and advertising.

Advertising has become the crown jewel. Instacart Ads lets consumer packaged goods (CPG) brands like Coca-Cola, Procter & Gamble, and Nestlé pay for sponsored product placements within the Instacart shopping experience.

When someone searches for "chips," Doritos can pay to appear first. This is incredibly valuable because it's advertising at the exact moment of purchase intent.

Ad revenue exceeded $900 million in 2023.

The retailer partnership model is key. Unlike DoorDash or Uber Eats (which listed restaurants without permission early on), Instacart works with grocers as partners.

Over 1,500 retail banners including Costco, Kroger, Albertsons, and Publix have formal partnerships. Instacart provides the technology and shoppers; grocers provide inventory and stores.

The idea started in Paris in December 2008. Travis Kalanick and Garrett Camp were at the LeWeb tech conference and couldn't find a cab.

Camp had been obsessing over the idea of summoning a car with your phone. He bought the domain UberCab.com, built a prototype, and recruited Kalanick to help run it.

The first version launched in San Francisco in 2010 as a black car service — not the cheap rideshare everyone knows today. You'd tap a button, a Lincoln Town Car would show up, and it cost about 1.5x a regular taxi.

Ryan Graves answered a tweet from Kalanick looking for an "entrepreneurial product manager" and became employee number one. He ran operations while Kalanick was still finishing up another startup.

Graves would later become CEO briefly before handing the reins to Kalanick. The app launched with just a handful of cars in San Francisco.

It worked so well that riders couldn't shut up about it.

The real inflection point came in 2012 when they launched UberX — regular people driving their own cars at prices cheaper than taxis. That one decision turned Uber from a luxury black car service into a verb.

Within two years, UberX was available in hundreds of cities and the word "Uber" had entered the dictionary.

Apoorva Mehta was a 26-year-old Amazon engineer in Seattle who quit his job in 2012 to start a company. The only problem: he had no idea what to build.

Over the next year, he started and abandoned roughly 20 different projects. A social network for lawyers.

A way to track restaurant wait times. Nothing stuck.

Then one day he was too lazy to go grocery shopping. He looked for a service that would shop for him and deliver everything to his door.

Nothing good existed. The existing options were grocery store delivery services that only worked during specific windows, had limited selection, and required ordering days in advance.

Mehta wanted to order groceries the way he ordered everything else online — immediately, from whatever store he wanted.

He built a prototype in 2012 and applied to Y Combinator. The demo was rough — he ordered a six-pack of beer through the app and had it delivered to a YC partner's house during the application process.

It worked. He got in.

Instacart launched in the San Francisco Bay Area in 2013 with a simple promise: order from your favorite local grocery store and have someone shop for you and deliver within an hour.

Uber

Uber's early growth strategy was beautifully ruthless. They'd roll into a new city, launch without asking permission, and deal with the regulatory fallout later.

They called it "Travis's Law" — it's easier to ask forgiveness than permission.

The playbook was simple: launch in a new city, give massive discounts to riders (sometimes completely free rides), pay drivers signing bonuses and guaranteed hourly rates, and flood the zone until the city was hooked. Then slowly raise prices and cut driver incentives once the market was locked.

They burned billions doing this but it worked — by 2016 Uber was in 500+ cities across 70 countries.

They also weaponized word of mouth with referral codes. Every rider could give free rides to friends.

Every new driver got a bonus for signing up. The viral loop was insane.

At peak growth, Uber was adding a new city every day.

Instacart

Instacart grew by solving a problem one city at a time. They launched in San Francisco, proved the model, then expanded to other major metros.

Each new market required recruiting shoppers, signing up retailers, and building enough consumer density to make the economics work.

The COVID-19 pandemic was the inflection point. Grocery delivery went from luxury to necessity overnight.

In March 2020, Instacart hired 300,000 new shoppers in a single month. Order volume increased 500%.

Years of planned growth happened in weeks. The pandemic proved that grocery delivery wasn't a niche — it was the future of how a significant chunk of the population would shop.

The enterprise play is the long-term moat. By providing white-label technology to grocers, Instacart becomes embedded in their operations.

Even if a grocery chain wanted to build its own delivery service, they'd need years and hundreds of millions to replicate what Instacart provides. The more deeply integrated Instacart becomes in grocery operations, the harder it is to rip out.

Uber

Where do you even start? Uber might have faced more simultaneous existential crises than any company in history.

Regulatory wars. Taxi unions, city governments, and entire countries tried to shut Uber down.

London revoked their license. France arrested two executives.

Uber was banned, unbanned, re-banned, and sued in dozens of jurisdictions simultaneously.

The toxic culture. In 2017, former engineer Susan Fowler published a blog post describing rampant sexual harassment, discrimination, and HR cover-ups at Uber.

It went nuclear. Investigation after investigation followed.

Board members resigned. Executives were fired.

Travis Kalanick's ouster. After the culture scandals, a leaked video of him berating an Uber driver, and a federal investigation into stolen trade secrets from Google's self-driving car unit Waymo, the board forced Kalanick to resign as CEO in June 2017.

Dara Khosrowshahi came in from Expedia to clean things up.

The cash burn was legendary. Uber lost $8.5 billion in 2019 alone.

They subsidized rides so heavily that riders were paying less than the actual cost of the trip. The company didn't turn its first operating profit until Q3 2023 — fourteen years after founding.

Instacart

The post-COVID hangover was brutal. After pandemic demand normalized, growth slowed dramatically.

The company's valuation dropped from a peak of $39 billion in early 2021 to about $10 billion at IPO in September 2023. Investors who bought at the peak saw a 75% paper loss.

The narrative shifted from "essential infrastructure" to "nice-to-have luxury."

Unit economics are perpetually tight. Paying a person to walk through a grocery store, pick items, bag them, and drive them to someone's house is expensive.

Unlike meal delivery (one restaurant, one bag), grocery delivery involves dozens of items per order, refrigeration requirements, and substitution decisions. Every order that requires a shopper to call the customer about an out-of-stock item eats into efficiency.

Amazon is the existential threat. Amazon Fresh, Whole Foods delivery, and Amazon's own logistics network represent a competitor with nearly unlimited resources and a Prime membership base of 200+ million.

Amazon has been willing to lose billions on grocery delivery to build market share. Instacart's advantage is retailer partnerships — Kroger and Publix use Instacart specifically because they don't want to help Amazon dominate grocery.

Uber

Uber Rides is the core product — get from A to B in someone else's car. UberX is the standard option, Uber Black is the premium black car tier, UberXL fits bigger groups, and Uber Reserve lets you schedule rides in advance.

Uber Eats is the food delivery arm and competes directly with DoorDash and Grubhub. Uber Freight is the logistics play — basically Uber for semi-trucks, connecting carriers with shippers.

Uber for Business lets companies manage employee rides and meals. Uber now also offers package delivery, grocery delivery, and even boat rides in some cities.

Instacart

Instacart Marketplace — the core platform where consumers order groceries from 80,000+ stores for delivery or pickup, with personal shoppers fulfilling orders. Instacart+ — subscription service ($9.99/month) offering free delivery on orders over $35, reduced service fees, and credit back on pickup orders.

Instacart Ads — a retail media platform letting CPG brands run sponsored product listings, display ads, and coupons within the shopping experience. Instacart Platform (Enterprise) — white-label e-commerce technology that lets grocers build their own online ordering and fulfillment powered by Instacart's infrastructure.

Caper Cart — AI-powered smart shopping carts (from the 2021 Caper AI acquisition) with built-in screens, barcode scanners, and payment that let shoppers skip the checkout line.

Instacart

Sequoia Capital was an early and consistent backer. Andreessen Horowitz invested in growth rounds.

D1 Capital Partners led the 2021 round that valued Instacart at $39 billion. Existing investors including Valiant Capital, T.

Rowe Price, Fidelity, and Tiger Global participated across rounds. Y Combinator was the starting point (Summer 2012 batch).

The September 2023 IPO on NASDAQ priced at $30 per share, valuing the company at approximately $10 billion.
