All 84 startups from Y Combinator’s S19 Demo Day 1

It’s that time of year, Silicon Valley’s investor technocrati and advice-giving Twitter celebrities descended upon Pier 48 in San Francisco to judge the latest summer batch of Y Combinator startups. TechCrunch was there, as well, and we were tapping away feverishly as co-founders pitched to woo investors.

There are 197 companies in total in the summer YC batch, we heard from 84 of them today — in addition to a few off-the-record pitches which we agreed to hold off publicizing as they remain in stealth. We’ll hear from another chunk of them tomorrow, so check back tomorrow for even more startup blurbs.

Demo Day used to be the debut for many of these companies, but as Y Combinator’s prestige has grown so has the likelihood that the batch’s best will be closing rounds at outsized valuations before the first pitches have been made.

We’ll undoubtedly be reporting on some of these rounds moving forward, but for now here are the 84 companies whose founders pitched onstage today at Y Combinator Demo Days – Day 1. You can also find the remaining 82 startups that pitched on Demo Day 2 here, as well as our 12 top picks from Day 2.

• Mighty: Mixpanel’s founder is at Y Combinator with his new startup, Mighty, a $20 per month cloud computer streaming service that’s just for Google Chrome (at the moment). Why pay for a free piece of software? The startup says that by streaming the experience from a beefed-up PC your most-used app will be considerably faster and only use 5% of your CPU. It’s a premium product with a tight niche, but the company has ambitions to support other software types as it builds out the tech.
• Hype and Vice: This startup combines the latest trends with college brands to make fashion-focused college apparel for women. Working with 11 universities to date, the founders say the company has grown 4x YoY, with margins of 84%; meanwhile, they have 50 additional college licenses in the pipeline.

• Lumineye: Lumineye wants to help first responders identify people through walls. In domestic violence disputes, hostage rescue or human trafficking situations, first responders often need help determining where humans are behind closed doors or other barriers. Lumineye’s team of four built a portable 3D-printed radar device that uses signal analysis software to differentiate moving and breathing humans from other objects through barriers like drywall, concrete, rubble and brick. For Lumineye, four pilot programs represent $90K in ARR. They’ve also just signed a $50K pilot with the U.S. Air Force. They’re also signed on to start testing with the FBI this fall.
• Flo Recruit: This is an applicant-tracking platform for in-person recruiting events. The startup helps companies scale their college recruiting efforts, saving time and money. The company says they have $8,500 in monthly recruiting revenue, counting Y Combinator itself as one of its customers.
• Gaiascope: Electricity trading is a $15 billion annual market, but it’s hard. Electricity is consumed instantly, which means the supply must always match the demand. That, however, leads to extreme price volatility. Traditional quant models don’t work, so this is where Gaiascope’s algorithms come in. Through its quant fund, Gaiascope enables electricity trading at more predictable prices. 
• Revel: Many of the venture-backed communities online seem to be geared toward 20-something dudes, but Revel is aiming to create an online-to-offline community group for women over the age of 50. The site is a $15 per month membership that gives you access to the community-hosted groups. Revel went live in the Bay Area last month.

• Node: Node wants to use an Ikea-like assembly process to build sustainable backyard cottages — a market the founders say is worth $100 billion and growing quickly. In the past year 25 cities have passed legislation to allow these buildings. Node ships a flat pack of materials that it says only take a few days to assemble into a turnkey backyard cottage or sustainable vacation home. They’ve sold 11 homes in the past two weeks, and the founders are optimistic that they could reach 50% margins with their tech. Early target markets include Seattle, Portland and Vancouver. 
• Prolific: A marketplace for finding survey participants on demand. Submit your survey, tell them a bit about your target audience, and they’ll find survey participants accordingly. They saw $185K net revenue in July, with 2.5x yearly growth through word of mouth.
• Juno College of Technology: JCT is creating the technical university of the future. The startup operates a coding bootcamp, expected to do $3 million in revenue by the end of 2019. Similar to Lamda School, they offer income-share agreements, but “the similarities stops there,” explained the founder. Juno says it places 87% of students who complete their nine-week long program. 
• LAIKA: In Latin America, it’s hard to buy pet supplies in person due to a reliance on bus transportation. LAIKA, an online pet supplies service for Latin America, aims to make it easier. The startup has $200,000 in monthly revenues and is growing 30% month over month. 
• ScholarMe: The startup is building what it calls the “Common App for college financing,” a single form that helps students pay for college. The company prevents prospective students from filling out endless forms to find scholarships, FAFSAs, income-share agreements and loans. 
• Sable: Getting set up with a bank is a slow process for people new to the U.S. It can take months for foreign-born people to get set up with a credit card and a checking account. Sable launched a mobile bank for international people in the U.S. that wants to expedite that process. The team has collectively worked on distributed teams that launched 14 banking products in the past. The company is currently managing credit cards and live checking accounts. With Sable, users can get set up with a credit card and checking account online in five minutes. In five days of launch, the company has 135 customers and is managing $200,000. Sable is targeting 4.5 million creditworthy internationals, and what it says is a $3.3 billion market in the U.S. alone. The team wants to eventually launch a suite of banking products like mortgages and student loans while they’re at the beginning of their financial independence in the U.S. 

• Metacode: “Better code search,” currently for Swift, TypeScript and Javascript.

The company says more than 700 engineers from companies like Pinterest and VueJS are currently using it. The cost is $25 per month per engineer.
• Fad Mania: This is an app that provides users with an endless stream of games with ambitions of being the next major social network. One of the first games was called Trump Punch, which got more than 100,000 organic users. The team realized most games don’t retain users and decided to create Fad Mania, which develops social-first games. Fad Mania has 1,000 weekly users.
• Breadfast: This startup delivers fresh bread, milk and eggs to customers in Egypt. Because Breadfast makes its own bread and works with farmers, its business has 35% gross margins with $180,000 in monthly revenue. For customers, Breadfast costs $18 per month per household.

The crowdfunding site can help families and friends amass cash and the startup will let people pay for services directly from the site, letting them take a slice on both sides of the transaction.
• Localyze: Localyze provides international employee relocation as a service. Employee relocation is an expensive cost for businesses, yet every year, two million people are moving to the U.S. and Europe for work.

• Hatchways: Learning to code online has kind of been a trope for people that are tired of their careers and are ready to do something new. The issue is that even if they get their skills to a great position that’s really only part of the equation. Hatchways is building a platform to help people who have learned to code online find internships and team projects. The startup is aiming to collect fees on both sides, from candidates looking to find opportunities and companies looking for new talent. They’re starting with software engineers but are also looking to expand into the finance space in the future.

However, there are currently no standardized hotel options in the country. Kuarti wants to provide another hotel booking option for standardized hotel chains that can be reserved online. The company wants to partner with independent hotels, to make small renovations and offer rooms for $35 per night.

The 21-year-old founder has been building rockets since he was 16, and is now managing a team of seven aerospace engineers with Epic Aerospace.
