Not everyone had a good time at the Apple WWDC conference.

Among the company's many product announcements were new services and features that expand Apple's list of competitors, research firm CB Insights reports. More than a dozen startups walked away from the conference "wounded" by the way Apple went after their customers, a practice known as "sherlocking."

Here are five of the startups that face new competition from Apple thanks to its new offerings. 

1. Spotify

One of the major announcements from WWDC was Apple's new paid music streaming service that starts at $10 a month. The feature could potentially help drown out 30 Under 30 alum Spotify, founded in 2008 and backed by venture capital firms including Kleiner Perkins and Accel Partners.

2. Flipboard

As Apple does away with its Newsstand feature and replaces it with Apple News, social network aggregation app Flipboard stands to lose out. Founded in 2010, the company collects news items and presents them in a digital magazine format and has backers in Insight Venture Partners and Kleiner Perkins.

3. Evernote

By upgrading its Notes app with new capabilities like photos, links and sketches, Apple is overlapping with note management app Evernote. The company founded in 2007 has investors including Troika Ventures and Sequoia Capital.

4. Glow

Apple's announcement that iOS 9 Health will include reproductive health tracking could create competition with serial entrepreneur Max Levchin's fertility app Glow. Founded in 2013, the company uses data analytics to help women predict their precise level of fertility on various days. Investors include Andreessen Horowitz and Founders Fund.

5. Pebble

The Smart Watch company founded in 2012 faces increased competition from the Apple Watch in light of the new features announced at WWDC, including voice memos, sketch colors, and custom mail replies. Pebble raised $10.3 million on Kickstarter in 2013 and raised Series A capital from venture firm CRV.
