Happy Cinco de LinkedIn!

Cinco de Mayo holds a special place in our hearts here at LinkedIn. In addition to being an excuse to down margaritas and tacos, it marks the fifth anniversary of the day we launched LinkedIn: May 5, 2003. The web was a different place back then; Friendster was the hottest site around, terms like “Web 2.0″ and “AJAX” hadn’t yet been coined, web pages were still in black and white… Okay, maybe it wasn’t that long ago.

As both a company and a tool, LinkedIn has changed dramatically. Here’s a quick “then and now” comparison of LinkedIn ‘03 and LinkedIn ‘08:

May 2003 May 2008
Employees 10 278
Users 4,800 22,000,000+
Introductions Sent 280 7,000,000+
Recommendations Made 0 4,500,000+
Questions Answered 0 1,000,000+
Four Square Games Played 0 6,394

Note that many of the features present in LinkedIn today — including Recommendations, InMails, Groups Answers, and Jobs — hadn’t been built in May 2003. (But we were already thinking about most of them!)

I’ve also put together a small gallery of screenshots showing how LinkedIn has evolved through the years.  What will LinkedIn look like 5 years from now? 10 years from now? Only time will tell…

LinkedIn through the years

And finally — as a bonus to anybody who read this far — here’s an easter egg from the old days.  Probably the last page I finished before the launch was our Founders page.  It took forever to get everyone’s bio together so, in the meantime, I wrote a few on my own.  We didn’t leave it this way for long, but here’s a screenshot for posterity.

  3. Hey Chris (and the rest of the LinkedIn Team),

    Congrats on making it to number 5!

    I have been a “card-carrying” member since January 2004 (6 month delay) and can only say that “it keeps getting better”.

    Keep up the good work!

  4. Heartiest Congrats! Three…err… Five Cheers for everyone in the LinkedIn team :) Keep Rocking!

  5. When I first started using LinkedIn I had to walk 10 miles in the snow uphill both ways just to add a new job to my profile. ;)

    Happy birthday!

  6. Congrats and Mazel Tov to LinkedIn! My growth in the past 18 months here has been almost as meteroric as LinkedIn’s growth in the past 5 years. I’ve been very pleased with the support that your staff has provided, and this site has helped advance my career and my research in ways I never thought possible. Many thanks!

  7. Thanks for sharing the LinkedIn 5 year birthday party with all of us! It really has evolved wonderfully during the past 5 years. Keep up the quality focus, as this is the premier professional virtual community. Thanks again for all you do!

  8. I have only been with you for three months. LinkedIN is on my short list of Web tools for business.
    Happy birthday and many more to come.

  9. Congratulations for your work !

  10. Happy Birthday LinkedIn Team!!
    I know how hard it is to maintain, develop and make grow a website…
    The ROI to hard work shows not only in statistics, but also in the way people show you how they feel about our work.
    So keep making our professional lives better and more international!!…

  11. How can I find out when I first posted my profile?

    Take care people. :-)

  13. @jeff: Click on “Account & Settings” at the top of any LinkedIn page. On that page, in the upper-right corner in grey text, you should see “User since: ” and the date you joined LinkedIn.

  14. Linkedin Rocks ! Happy Birthday !!

  15. Congratulations LinkedIn.

    I predict a great future, provided you are able to facilitate much easier ability to network.

    I realize that perhaps was not the initial intent, but it is the future of all these media platforms.

    They must provide for full multimedia, fully converged Profiles and 1:1 interaction. The existing platform and group system will not meet these demands. The membership base needs to be segmented into niches in a far more effective way.

    Not to be critical. Just added some constructive thoughts for the next 5 years!

    Again, congratulations!

  16. I LOVE LinkedIn. It’s helped me in business in countless ways. Keep up the good work, and I’ll keep promoting LinkedIn as a nearly necessary business tool.

  18. Happy Birthday!

    Steve

  19. Hello Linked In Team,

    Congratulations!

    You are now a leader in Corporate relationship space. I commend and congratulate all of you for continuously improving the site to make it more effective.

    One Suggestion;

    Can you improve your Groups area, as we do not have any place where Group members can post their messages or ask questions within the group space and originator can post group related activities, events, pictures etc.

    This would greatly help!

    Keep up the good work!

    Ash

  20. I am sooo addicted to this site. It is a great success… Happy Cinco Birthday! and Wishes for many more.

  21. Five years??

    Unbelievable!! Linkedin becomes part of my life.

    Congratulations! Happy 5 years! See you for the next 50.

  22. 5 years old, still the age of innocence!
    May the next 5 years be a similar success story!

  23. I love LinkedIn. A great business tool that helped me in business in countless ways.
    Happy Birthday LinkedIn!!!

    Anyone may feel free to connect with me.

  24. YOU GUYS ROCK! Seriously, not only was it brilliant to capitalize on the whole 6 degrees of separation concept – but you’ve built an incredibly useful tool! MUCHO GRACIAS & Feliz Cumpleaños! ;-)

  25. Chris:

    Can you fill in the blanks with the number of subscribers on LinkedIn on Cinco de Mayo 2004, 2005, 2006, and 2007?

    Here in Mexico they say “Feliz Cumpleaños” on your Birthday. So have a very happy one Linked In. Don´t have too many Margaritas! Thanks for the profile, and the memories. I look forward to Linking with many, many, more of you, and posting on many more Anniversaries. Provecho!

  47. Linkedin is a great tool for every professional. Thanks for making it such an indespensable & effective tool.
    Happy Birthday Linkedin!!!!

  48. To the LinkedIn Team:
    Sorry for this short story, but I think is a good moment to share it with you…

    Almost four years ago, I was working really hard with no time for “surfing” the web.

    A friend of mine invited me to join LinkedIn at this moment, but without time to explore the site a little bit, I rejected his offer three times.

    I thought (with some prejudices) that LikedIn was a kind of site for dates, mail chains, musical e-cards…

    This year, I was looking for an old friend of mine and I found him at LinkedIn. So I decided to pay attention to this all-new-site for me.

    Now, I consider it as a very powerful tool for job seekers, and a special reference for looking for friends and contacts.

    I can only tell you… GREAT JOB and CONGRATULATIONS for the first 5 years and the many more years to come!!!

  51. Congratulations on achieving such a dynamic and transformatory business tool! Happy Birthday, and Congrats to the team for making the linkedin vision a huge success!

    I think the opportunity is limitless for what can be acieved when we synergize business & social goals. Thanks linkedin for making this more feasible than ever before. I will definitly be spending more time on linkedin this year, and welcome connecting with new great people leading today’s companies & npo’s.

    Cheers, Brenda
