Y Combinator Demo Day, revenue-based VC funding, Pivotal, Dell, Tumblr, WeWork, and more

Editor’s note

Due to bad travel logistics (thanks SFO), I wasn’t able to get the mid-week edition of the Extra Crunch roundup newsletter out. Sorry about that. Instead, here is everything we published this week on Extra Crunch in one fell swoop — and my, we covered a lot of ground. Hope you enjoy some great weekend reading.

Y Combinator Demo Day Coverage-a-palooza

Much like the equinoxes that synchronize Earth’s calendar, Y Combinator’s biannual demo days are a key fixture of the Silicon Valley calendar. This year was no different, with 166 companies presenting from the summer batch (and occasionally from previous batches if they chose to delay their presentation).

We had a full squad on site not only covering the 84 companies from day one and 82 companies from day two, but our team also put their collective heads together to identify the top companies from each set exclusively for Extra Crunch members.

The 11 best startups from Y Combinator’s S19 Demo Day 1

Read our favorite 11 startups from day one, which included:

PopSQL provides collaborative SQL query editing. You can store SQL queries you run regularly, grouping them into folders that can be kept private or shared amongst your team. Version history tracks changes so it can be reverted if/when something breaks. It currently has more than 100 paying companies, and is making $13K per month. It plans to build a marketplace for apps that run on top of your company’s database.

Why it’s one of our favorites: SQL database queries can be a nightmare, especially if they’re not something you’re used to dealing with every day. PopSQL lets you hammer on queries collaboratively until they’re working exactly as you want — then you can save them for future use and share them amongst your team members. And when you’ve spent the last 45 minutes trying to figure out why your query isn’t working only for a team mate to fix it in thirty seconds, you can use version control to see exactly what they changed. PopSQL says its product has already found customers in companies like Instacart, Redfin, and DoorDash.

Our 12 favorite startups from Y Combinator’s S19 Demo Day 2

Read our favorite 12 startups from day two, which included:

Business Score is helping companies automate background checks on other businesses. The startup is looking to stamp out tired manual processes that largely mean picking up the phone and scouring documents. The single API taps data sources across the web to build out real-time profiles that can help customers scan businesses in an effort to prevent fraud, qualify leads and onboard new clients.

Why it’s one of our favorites: Though it’s yet another startup in the batch catering to other startups, we thought Business Score stood out. The company integrates with thousands of data providers to help companies verify other startups and enterprises they are considering doing business with, using a system they’ve dubbed “the business passport.” There’s an opportunity here to create a tool essential to company-building across industry.

YC is doubling down on these investment theses in its most recent batch

Finally, amidst all the zany craziness of watching 166 companies present over two days (there should be a YC company for unmelting your brain), our venture capital reporter Kate Clark stepped back to assess what all the various companies in the batch indicated about the accelerator’s strategy these days.

YC knows its sweet spot: enterprise SaaS. One might go as far as to say it’s transitioning into a full-on SaaS incubator. Why? Because one of the greatest advantages of going through YC is the network of alumni companies you can tap into. Many successful B2B companies have emerged from the program, raised boat loads of venture capital funding and rocketed to the moon (hello Stripe, Brex, Gusto and Atrium). With that in mind, YC is doubling down on its resources for startups that sell products to other startups, which brings us to our first piece of news.

YC chief executive officer Michael Seibel and president Geoff Ralston announced this week that the accelerator has implemented something called CTO and HR demo days. In short, CTO and HR demo days are an opportunity for B2B startups to pitch their products to YC alum companies’ CTO and/or head of HR. Seibel and Ralston said 60 CTOs attended the event, as well as 30 HR heads. In total, 42 startups presented and we’re guessing a bunch of those companies booked a few customers.
