By comparison, a number of startups and innovations have emerged in the past five, 10, 15 and even 20 years ("Gen Z"-aged, if you will) that are now approaching the same level of household-name status. Some are still in the startup phase, while others have been acquired (or have acquired others) and continue to grow.

Many of the internet companies whose products we use today had to either survive the dot-com bubble at the turn of the millennium or rise from the ashes afterwards. Then, of course, there are some that have arguably already reached and passed their prime in the 21st century alone, as technology has evolved further.

While this is by no means a comprehensive list, click through the slides to see which businesses are celebrating milestones in 2018.

Soylent (2013)

In February 2013, a twentysomething electrical engineer named Rob Reinhart published a blog post that went viral. In it, he described a meal substitute substance he had created with the goal of saving time, money and the hassle of procuring food while ingesting all of the nutrients his body needed.

"I feel like the $6 million man," Reinhartwrote. "My physique has noticeably improved, my skin is clearer, my teeth whiter, my hair thicker and my dandruff gone. My resting heart rate is lower, I haven't felt the least bit sickly, rare for me this time of year. I've had a common skin condition called Keratosis Pilaris since birth. That was gone by day nine. I used to run less than a mile at the gym; now I can run seven. I have more energy than I know what to do with."

Today, his creation,Soylent, named after the movieSoylent Green(but not made from people!) is available in various flavors and formats and has expanded into retail sales with Amazon, 7-Eleven and other partners. Last year, the companyraised $50 millionin a series B funding round, after recovering from some bad press when it made consumerssick.
