Investors got plenty of new technology companies to pour their money into last year. Companies that have gone public on U.S. markets include Alibaba, Arista, Castlight, GoPro, Hortonworks, HubSpot, Lending Club, New Relic, and Zendesk. And plenty others should be arriving in 2015.

A new group of tech companies have joined CB Insights’ billion-dollar valuation club thanks to substantial funding rounds this year, paving the way for some hefty exits in the months to come. A few companies could well have gone public in 2014 but have held off. (The best example is Box.)

After going down the list from CB Insights and reviewing our own news coverage on VentureBeat, we’re left with no shortage of tech IPO contenders for the coming year.

Without further ado, here’s our list of 27 to watch for.

  • Actifio: The company developed a way to pare down the number of copies of a given piece of data while ensuring it will be available whenever someone needs it. Back in March, Actifio’s valuation was “a good $100 million over $1 billion,” founder and chief executive Ash Ashutosh told VentureBeat.
  • Airbnb: It’s not clear that the company is ready to go public, but this doesn’t mean it’s an impossibility. In August, Airbnb disclosed that it had taken on a whopping $475 million funding round.

  • It’s a website for buying and selling commercial and residential real estate. People have spent more than $26 billion on properties through the site as of March.
  • AppDynamics: The application performance-management and analytics software provider made the 2014 tech IPO list and brought in $120 million of new capital in July. Competitor New Relic just went public, and it’s only natural that AppDynamics, which has managed to get its service running inside corporate data centers, will eventually move in that direction, too.
  • Applause: Formerly known as uTest, the startup made this year’s Billion Dollar Club list from CB Insights. It offers application-testing services. It started in 2007 and now includes Google and Netflix on its customer list.
  • AppNexusIt’s an advertising-tech company based in New York that companies can use to customer their ad exchanges or ad networks.
  • Box: The cloud file-syncing and -sharing provider has gone more deeply into specific industries this year and also landed major partnerships. But Box backed away from an IPO, so it wouldn’t be surprising to see the company hold off for another few months. It initially filed its S-1 in March, and since then it’s been improving its finances.
  • ClouderaOf the companies that sell distributions of the Hadoop open-source software for storing, processing, and analyzing lots of different kinds of data, Cloudera is the presumed leader. But last month another one of those companies, Hortonworks, went public. Cloudera picked up hundreds of millions of dollars in an investment from Intel in 2014, and an IPO could be its next big announcement.

  • DataStax: This company, which commercializes the popular Apache Cassandra open-source NoSQL database, announced in September that it had taken on a $106 million funding round.
  • DataXuThe Boston ad-tech company carries a valuation above $1 billion, according to CB Insights.
  • DocuSign: The company known for providing e-signature capability for documents, announced in March that it had raised $85 million.
  • Dropbox: The cloud file-sharing company has made several acquisitions in the past year, and in February the company issued a regulatory filing showing a $450 million offering.
  • Good Technology: Good, with apps for businesses that enables their employees to use mobile devices securely, took on $80 million last year after filing to go public in May.
  • Host Analytics: A provider of cloud-based enterprise performance management software, Host last month announced a $25 million round. Host boasts that it can save companies money in terms of total cost of ownership in comparison with enterprise software giant Oracle.
  • Lithium: The social media software company has been around since 2001. In 2014 it bought Klout.
  • Lookout: The mobile security company recently wrapped up a $150 million funding round.

  • MapR: Like Cloudera, it’s a Hadoop distribution vendor, and its customer count has exceeded 700, according to a statement in December.
  • MindBody: The provider of web-based booking and point-of-sale software has gained traction in the health care industry in particular, and it appears to be planning an IPO this year. A VentureBeat source close to the company suggested as much in August.
  • MongoDB: The company behind the trendy NoSQL database by the same name had made the 2014 tech IPO list but did not make a whole lot of news in 2014. The company did appoint a new chief executive, Dev Ittycheria.
  • MuleSoft: The application-integration company announced a $50 million round in March.
  • Ping Identity: The company has made itself known in the business of identity management and single sign-on. The company expanded its mobile authentication capability in 2014 by buying Accells Technologies.
  • Practice Fusion: The electronic health record company has picked up quite a bit of new business in the past year and also positioned itself to be easy to use on tablets.
  • Telogis: The company with cloud software for managing vehicle fleets took on its first funding round, totaling $93 million, in late 2013. It’s been around since 2001.
  • Uber: Oh, Uber. The company with a mobile app for summoning a ride in cities all around the world has become one of the most highly valued private companies around. Meanwhile it has also found itself dealing with a plenty of controversy, regulatory and otherwise.

  • Xero: The accounting software company actually came out and said this year that it plans to go public in the U.S. in 2015. The New Zealand company’s stock is already traded on the New Zealand Exchange; it’s valuation was at $2.7 billion in July.
  • Yext: The New York-based company lets businesses control their listing information online. It raised a $50 million round in the middle of last year.
  • Zuora: The company provides commerce, billing, and finance tools for cloud-based software vendors. Box, SendGrid, Xactly, and Zendesk, among others, have bought in.
