Today was the second half of Y Combinator’s two-day Demo Day for its Winter 2019 class. Over 85 startups pitched on stage yesterday, and another huge batch launched today.

Previously held at the Computer History Museum in Mountain View, this YC Demo Day instead took over a massive warehouse in San Francisco. Like yesterday’s pitches, today’s were split across two stages (“Pioneer” and “Mission”) running in parallel — so even if you were there, you couldn’t see everything alone. We picked our top 10 startups from Day 1 to make it easier to keep up. You can check out our 9 favorite startups from Day 2 here.

Here are all of the companies that launched today, and our notes from their presentations.

Pioneer Stage:

YSplit: Splitting utility bills and other recurring payments with roommates or loved ones is a huge pain where one person has to front the money and then nag the others to get paid back. YSplit offers virtual debit cards that make it easy to automatically split bills and collect cash from users’ bank accounts. By charging a 2 percent interchange fee to merchants, YSplit could build a solid business from the 26 million shared homes in the US alone.

The Juggernaut: A subscription publication focusing on South Asian stories. They hire freelance writers, publish one story per day, and charge users $5 a month. We wrote about The Juggernaut here.

Searchlight: Reference checks can screen out bad hires, yet many businesses wait until the very end of the interview cycle or don’t do extensive checks. Searchlight offers reference checks as a service. Job candidates invite their references to submit testimonials, which Searchlight collects and organizes into reports about someone’s work style, ideal environment, and skillset. Searchlight earns an average of $250 per job hopes to investigate all 30 million skilled hires in the US per year.

Allo: Connects local parents and helps them help each other with things like babysitting and errand-running through a “Karma” point system. Average user returns 12x per week.

Coursedog: Universities employ full time scheduling administrators to place faculty into courses and rooms. Coursedog automates this process by plugging into a school’s data to eliminate this busy work. Coursedog already has 8 university clients paying over $100,000 for a three-year contract. Next it wants to move into modernizing the process of booking spaces on campus as well as instructor and tuition payments.

AI Insurance: Cloud-based software for insurance claims. By moving things to the cloud rather than filing cabinets, the founders say they can save “thousands of hours per claim”. Their goal, once they’ve got enough claim data, is to use AI to determine things like how much a claim might ultimately cost.

Nebullam: Growing crops indoors can produce more food per acre that’s not dependent on weather, but the problems are the high labor costs and payback times for expensive equipment. Nebullam wants to be the John Deere of indoor farming. It sells a vertical farming cube and other equipment that can maximize yield and minimize costs. With a CEO who grew up on a farm, it’s already managed a 3 year payback time for its equipment vs an industry standard for 7 years.

Pronto: Ride-sharing for smaller cities in Latin America. Co-founder Miguel Martinez Cano says that the Uber model doesn’t work in these cities, as would-be riders don’t have credit cards and instead want to pay cash. Drivers pay a subscription fee of $59-99 per month. Currently doing 62,000 trips per month.

LEAH Labs: People spend $500millionperyearonchemotherapyfortheirdogs,eventhoughthetreatmentonlyextendstheirlifetemporarilywithoutcuringtheirdisease.LEAHLabswantstocureB-celllymphomacancerindogsusingCarTcells,apowerfulnewtreatmentmethod.Therehavebeen$20 billion in recent Car T cell company exits, but none of the big players are focused on dogs. LEAH Labs falls under the USDA instead of the FDA, so it requires less investment to get approved, which translate into $5,000 treatments.

Balto: A platform for fantasy sports league managers to make money from their work. As fantasy sports betting moves toward legality in more states, they want to capture the audience already making bets through other means.

Visly: Developers waste a ton of time rebuilding the same product for iOS, Android, and web and Visly says only 15 percent of developers use tools to simplify this. Visly’s cross-platform UI development suite makes it quick and easy to create consistent apps for different devices. The CEO worked on Facebook’s version called Yoga, but it never achieved full compatibility with the web.”.. Visly has fixed those problems so developers can focus on their invention, not porting it to other operating systems.

Mudrex: Lets people do algorithmic trading without programming knowledge, beginning with cryptocurrency. Last week, they saw a trading volume of $150,000.Theychargeusers$300 a year for access to a drag and drop interface for building trading models, which the user can then test against historical trading data.

Brain Key: Diagnosis for brain diseases using 3D MRI data. Whereas many doctors use 2D slices from MRIs for diagnosis, Brain Key says they’re able to analyze data in 3D to do things like identify Parkinsons subtypes 35% more accurately than experts. They’re aiming to be in hospitals worldwide within 2 years.

Switchboard: It’s tough to efficiently match available trucks with freight needing to be shipped if you don’t know where the trucks are. Switchboard’s on-board truck sensors collect real time data on a truck’s location, destination, and more. Switchboard’s trucking freight marketplace launched three months ago and is already gathering data that could unlock more revenue streams.

Shef: Two months ago, California passed the first law in the country legalizing the sale of home cooked food. Shef creates a marketplace where home chefs can find nearby customers. Shef’s meals cost around $6.50comparedto$20 per meal for traditional food delivery, and the startup takes a 22 percent cut of every transaction. It’s been growing 50 percent week over week (Correction: we previously wrote “month over month”; YC tells us that growth was week over week) thanks to deals with large property management companies that offer the marketplace as a perk to their residents. Shef wants to be the Airbnb of home cooked food.

Qwest: Lets people pay money to skip lines at venues like clubs and bars. They’re currently at 10 venues in 2 cities, and say they should be at 100 venues in 6 cities this year. They aim to expand to events like music festivals and sporting events.

Circumvent Pharmaceuticals: Brain disease Batten, the Alzheimer’s of children, has no adequate treatment. Circumvent says its treatment can replace the missing enzyme at the root of the disease and has already been shown to be effective in mice. If it can get through expedited approval thanks to incentives for treating rare diseases, Circumvent wants to sell its medicine for $100,000 which is covered by insurance. Once it clears that hurdle, Circumvent will be much closer to working on Alzheimer’s treatments which could be hugely lucrative and a big win for humanity.

Withfriends: Membership programs for small businesses like bars, theaters, and barbershops. So far they have 80 small businesses on the platform, with over 5000 members working out to $400,000 in revenue. By integrating right into PoS machines, they say 15% of customers convert into members.

Co-founder Benjamin Fernandes says NALA is 7X faster than competitors and has 5,000 active users. NALA earns money off commissions on airtime and bill payments, interest on savings, sending leads to insurance companies and other services.

Founder Matthew Curtis notes that their model is currently not legal, but they’re actively trying to change that.

GoLinks: Long, complex URLs make it tough to access internal company tools. GoLinks makes links short and easy to remember for clients like Reddit and Lyft. Its tool can programmatically generate URLs that are single sign-on compliant, and teams get a dashboard of analytics. Whether employees are setting up a new computer or working while traveling, GoLinks means they won’t be locked out.
