Y Combinator’s incubator classes have gotten huge.

With over 200 companies, the Winter 2019 class is by far YC’s largest yet. Meanwhile, the incubator prepares to shift its headquarters from Mountain View to San Francisco.

It’s so large, in fact, it’s had to change the way it does Demo Day. Rather than all pitches happening on one stage, they were split across two stages (the “Pioneer” and “Mission” stages) running in parallel. So even if you were in the building, you couldn’t see all the pitches in person.

We were there — and as we do with each class, we’ve brought back our notes on everything we saw. Here are the 85+ companies that pitched today. Come back tomorrow for Day 2!

Pioneer Stage

Career Karma: Hundreds of millions of people will need to change jobs in the coming years. Career Karma gives them a placement quiz and gets them accepted at coding bootcamps and other training programs that pay the startup $1,000 per student. With income-sharing agreements growing in popularity, plenty of job skill providers will be willing to pay to enroll the highest potential students.

VanGo: An on-demand ride service for getting your kids and teens around. The founders say that, because “moms trust other moms,” 85 percent of drivers on their service are moms and all of them are women. They plan to expand into other verticals to help parents down the road.

Team Mobot: Simulated user interface testing doesn’t catch all the bugs and can be complex for less tech savvy companies to perform. Team Mobot offers a fleet of robots that physically test any app’s UI on real devices to perform QA testing and spot bugs. Team Mobot’s fleet learns over time to increase accuracy, and the startup plans to invade the Internet of Things and medical device verticals next.

Bento Club: Cheaper lunch delivery for office workers. Customers pre-order food from a select set of restaurants, and Bento picks it up and brings all orders to a shared pickup spot within one block of the customer’s office. Thirty-eight percent of customers come from referrals.

Basilica: Most teams trying to build artificial intelligence systems don’t have enough data, and that data can be expensive to collect. Basilica says its transfer learning method allows businesses to create accurate AI with just 1,000 data points instead of 1 million. Basilica generates network effect by using data from across its clients to improve efficiency for each vertical that teams will need to keep up with Google.

Keynua: In Latin America, signing documents requires tedious identity verifications. With Keynua you record a short video to verbally agree to a document, and they use existing records to verify your identity. This team’s previous product (Cinepapaya) was acquired by Fandango in 2016.

Lumos: Doctors use Google 40X more than professional tools for finding medical information, but Google is full of ads and results are meant for patients not doctors. Lumos offers a medical Q&A search engine for doctors who pay $15 per month. A trial at UPenn saw half of the med students using Lumos each day within weeks of launch. Lumos says it has more potential business opportunities based off understanding what studies and info doctors trust, and having access to them at critical decision points during treatment.

Traverse Technologies: Traverse uses software to identify potential sites for wind and hydro power generation. The company then buys and resells those sites. They estimate that a plot that they buy for $750k can be resold for $5 million. The currently have about $50 million worth of letters of intent.

Basement: A social network for your close friends. Feed broadcasting social networks feel impersonal, and inevitably bloat with distant acquaintances you’re shy about sharing with. Basement is designed for college students and grads to just add their best friends. It offers Instagram-style posting tools, but the intimacy leads to comment threads that feel more like WhatsApp chat. Basement will have to get users to break the social contract of courtesy so they don’t friend the wrong people, but has a chance to be where Facebook wants to go.

CosmicJS: A drop-in, easier to manage alternative to WordPress. The company says that KFC, MLB, and Dailymotion are already customers. Currently making roughly $10k in monthly recurring revenue, and they say that’s growing about 15 percent monthly.

Ravn: Looking around corners is one of the most dangerous parts of war for infantry. Ravn builds heads-up displays that let soldiers and law enforcement see around corners thanks to cameras on their gun, drones, or elsewhere. The ability to see the enemy while still being behind cover saves lives, and Ravn already has $490,000 in Navy and Air Force contracts. With a CEO who was a Navy Seal who went on to study computer science plus experts in augmented reality and selling hardware to the Department Of Defense, Ravn could deliver the inevitable future of soldier heads-up displays.

54gene: 54gene aims to be 23andMe for Africa. The company says that competitor data is limited because their users are mostly white. By focusing on Africa, the company can help detect and identify DNA markers that might otherwise go overlooked. Co-founder Abasi Ene-Obong has a PhD in cancer biology from the University of London.

Slapdash: Enterprise apps run slow and it can be tough to find files or messages across them. Slapdash creates a desktop software-speed container in which workers can run all their office software like Slack, Dropbox, Asana, Salesforce, and Google. Users can search across all their apps and be more productive, luring SaaS subscriptions from their employers.

YourChoice: Male contraceptive pill. With “two of the world’s leading sperm physiologists”, YourChoice says they’ve created a pill thats 100% effective with “no side effects” by targeting the ABHD2 and ANT4 proteins in sperm. They’re also working on a hormone-free contraceptive pill for women.

AccioJob: Only one-third of India’s college graduates get placed in jobs because their schools often only expose them to local recruiters. AccioJob charges colleges $10,000 per year to place their students in jobs, and charges employers per placement. Since it gains student contact info and grades, AccioJob can become the gateway to the best Indian college grads as more students from the country begin to enroll.

CentaurLabs: Hires doctors to label medical imagery datasets at scale, which can then be used to train AI. In the future, they’re aiming to build a diagnosis system to provide second opinions for doctors and patients.

Travelchime: Planning travel requires cobbling together Google Docs, maps, blogs, friend recommendations, inspiration apps, and booking sites. Travelchime combines travel planning tools into a Google Doc-style interface that automatically suggests contextual information and places popular amongst travel writing that it’s indexed. Users can then book from Travelchime, which hopes it can build a more helpful version of TripAdvisor.

Seawise Capital: Trade loans for exporters in India. The founders say they make 10% on every loan, and have taken on $550k in loans in the past 6 weeks. They plan to raise $5 million in debt by Q3 2019, and $25 million in debt by Q1 2020.

PerShop: Shopping online can be frustrating because you’re either hopping between individual brands without comparative pricing, seeing too many irrelevant products on aggregators, or can’t checkout on social apps. PerShop is a personalized shopping site that only recommends you items from your favorite brands, in your size, in your price range. Eventually it plans to sell personalized, targeted e-commerce ads. PerShop gets smarter as people use it to buy or just for entertainment.

Prometheus: Removes CO2 from the air to make gasoline. They say they can make gasoline for about $3.00 per gallon. Whereas past attempts required massive distillation columns, founder Rob McGinnis says he was working with carbon nanotube membranes when he discovered a cheaper way to do it with much less real estate.

Unicorn: Scooter companies that rent by the minute lose 2 percent of their fleet per day to damage and theft, and that means customers don’t have a safe scooter available when they want one. Unicorn rents scooters by the week or month and is already profitable. Vehicles aren’t left outside overnight and spend more time rented, while customers know there’s a scooter available for them without having to buy one outright. Unicorn’s founder started Tile and now he wants to build a better unit economics business than Lime and Bird.

Loonify Space: A bespoke launch system meant specifically for carrying small satellites into orbit. A balloon carries rocket to 35km and launches it mid-air. They have Letters of Intent for 155 satellite launches, worth a total of roughly $77 million. They intend to have their first launch on May 9th.

Supernova: Programming apps based on design mockups can be tough internally, but expensive and hard to maintain if outsourced. Supernova converts designs into production-ready code that follows best practices so it’s easy to update. Supernova’s AI can understand a product’s purpose and distinguish between navigation elements, buttons, and more. As more businesses try to modernize with tech products, Supernova could let them focus on their utility rather than computer science.

Kovi: Provides rental cars for on-demand drivers in Latin America. They currently have around 300 cars on the street, with 3,000 rental requests this year. The company estimates that 70 percent of drivers in Latin America rent/lease their vehicles.

If something goes wrong but goes undetected, the robots can physically destroy themselves. Overview uses cameras and AI to monitor manufacturing robots, shutting them down if something goes wrong.

Sunsama: A task manager that integrates with SaaS tools like Trello, JIRA and Asana to help workers identify and manage the tasks they should be working on a specific day.

Kalshi: Instead of just betting on sports, Kalshi lets anyone bet on anything, like whether Brexit will happen by the end of the month or who will win an Oscar. Users bet against each other so it’s more like a futures market than gambling, and regulators like it since Kalshi doesn’t earn more when users lose. It already has 2 licenses making it legal in 200 countries and is in talks with US regulators to earn 7 percent transaction fees when people bet.

Volk Wireless: Volk is making an Android smartphone with a free data plan, no carrier required.

Middesk: It’s difficult to know if a business’ partners have paid their taxes, filed for bankruptcy, or are involved in lawsuits. That leads businesses to write off $120 billion a year in uncollectable bad debt. Middesk does due diligence to sort out good businesses from the bad to provide assurance for B2B deals loans, investments, acquisitions, and more. By giving clients the confidence that they’ll be paid, Middesk could insert itself into a wide array of transactions.
