Taking a page from the playbooks of Google and Facebook, salesforce.com is ‘acq-hiring’ Microsoft-nurtured talent. The CRM giant announced on Tuesday the tiny acquisition of team collaboration SaaS startup Thinkfuse. The target immediately ceased operations and terminated its service, suggesting this was more of an acq-hire than anything else. Through the deal, salesforce.com gets its hands on about five employees, three of whom have had software engineering experience at Microsoft, according to their LinkedIn profiles.

Although three of the four acquisitions salesforce.com has announced this year (including Thinkfuse) have been tiny transactions, this small trend likely doesn’t represent a shift in M&A strategy. The company has a history of buying young firms, primarily for technology tuck-ins. According to The 451 M&A KnowledgeBase, the average time from when a company was founded to when it sold to salesforce.com is just under four years. What’s also notable, though, is that salesforce.com’s last team collaboration acquisition – Stypi, announced in May – was also a small acq-hire. However, the Stypi service is being maintained, at least for now.

There’s no denying that behavior in the equity markets is one of the main influencers on big-ticket M&A. Stock market stability provides a vote of confidence for corporate acquirers to pursue large, game-changing deals. Without stable markets, the valuation gap between buyers and sellers becomes too wide for potential sellers to accept. As a result, when the equity markets dip, so too does deal volume.

Nearly every drop in the tech-heavy Nasdaq Composite stock index coincided with a drop in both the volume and value of acquisitions of publicly traded technology companies. (Note: we’ve limited the scope of this research to the acquisition of Nasdaq- and NYSE-listed companies valued at more than $250m.) The number of acquisitions of large public companies tracks the stock market so closely that while the Nasdaq ended 2011 basically flat from the prior year, so too did the number of large tech transactions.

By early 2012, the Nasdaq had effectively regained the level it held before the credit crisis. Despite this bull run, however, there’s very little certainty or stability in the equity markets. Although not a flawless metric, we can use predictions for the IPO market as a gauge of 2012 activity. A stable stock market is desired before a private company hits the public stage. According to our 2011 Tech Banking Outlook Survey, which forecasts activity for 2012, bankers expect the public markets to be stable enough to welcome 25 new technology firms this year – the same number predicted for 2011.

But the number of IPOs is only half of the equation, as subsequent stock performance shows longer-term confidence in the newly public companies’ businesses. In 2011, we saw a number of fairly successful tech IPOs, many of which came from the consumer technology sector, such as LinkedIn and Zynga. But some of these vendors’ initial good fortunes were short-lived. LinkedIn, for example, has lost one-quarter of its market value since the company debuted in May 2011, and Zynga is trading below its offer price.

Among the top issues affecting stock markets are progress toward resolving or containing the European debt crisis and an agreement by the US congress on a bipartisan plan that would reduce the federal deficit by at least $1.3 trillion over the next 10 years. A full 85% of tech bankers surveyed answered that progress on the European debt crisis would increase M&A activity, while 73% said the same about progress on reducing the federal deficit. However, neither of these issues seems likely to be resolved anytime soon. The European sovereign debt crisis appears particularly hairy, after credit rating agency Standard & Poor’s recently downgraded nine major European nations’ credit ratings. Meanwhile, presidential election season in the US is likely to cause most to focus on campaigning rather than the federal deficit. While many weigh their options in voting for the next US president, the stock market may lose its vote of confidence, and deal volume could decline as a result.

While talk of social companies hitting the public markets has so far focused on US firms such as Facebook, GroupOn and LinkedIn, the first vendor to do so may actually come from the Far East. Dubbed the ‘Facebook of China,’ Beijing-based Renren filed its prospectus on Friday and will reportedly hit the NYSE in two weeks, trading under the symbol RENN.

Founded in 2002, Renren today offers social and professional networking, online commerce and gaming to an audience of approximately 117 million. According to its prospectus, the company added an average of two million users per month during the first quarter. Sales have grown at a similarly quick pace. Net revenue soared from $13.8m in 2008 to $76.5m in 2010, representing a compound annual growth rate of 136%.

Excluding underwriters’ overallotment options, Renren will offer a total of 53.1 million American Depository Shares (ADS). (Lead underwriters are Morgan Stanley, Deutsche Bank Securities and Credit Suisse.) The company expects to price at $9-11 per ADS, which at the top of that range would be a whopping $584m raised. However, if interest in previous Chinese IPOs is any indicator of what to expect, then Renren’s total amount raised could be significantly higher. Just two weeks ago, Beijing-based security vendor Qihoo 360 Technology made its debut on the NYSE, offering 12 million ADSs (excluding underwriters’ overallotment shares). Shares hit the market at $27 each, nearly twice the expected initial offering price of $14.50, and eventually closed at $34 each. Shares have dipped a bit since then, but Qihoo is still sporting nearly a $2.5bn market cap, which is approximately 43 times its 2010 sales of $57.7m.

At a time when the social networking bubble is quickly deflating, micro-blogging startup Twitter seems to be living in an alternative universe. We are, of course, referring to the much-publicized $1bn valuation the San Francisco-based company received in a recent round of funding. The rich funding dwarfs even the kinds of valuations we saw during the height of the short-lived social networking bubble last year. And it’s pretty difficult to justify Twitter’s valuation based on its financial performance, since the money-burning startup has absolutely no revenue to speak of, nor a clear plan of how to change that. It seems the entire valuation is predicated on the impressive user growth it has experienced over the past year, as well as the charismatic founders’ wild dreams of ‘changing the way the world communicates.’ That’s pretty thin, particularly when compared to LinkedIn’s funding last year at a similar valuation. That round, which was done at a time when the social networking fad was near its peak, nonetheless had some financial results to support it. Reid Hoffman’s startup was profitable on what we understand was about $100m in revenue and a proven and lucrative business model.

The interesting development from this latest funding is that it makes a sale of Twitter less likely, we would argue. This may be fine with the founders, who have drawn in some $150m for the company and will (presumably) look to the public market to repay those investments at some point in the future. But without any revenue to speak of at this point, any offering from Twitter is a long way off. Also, an IPO by Twitter in the future hangs on successful offerings from Facebook and LinkedIn, which are far more likely to go public before Twitter. If both of those social media bellwethers enjoy strong offerings, and Twitter actually starts to make money off its fast-growing base of users, then a multibillion-dollar exit – in the form of an IPO – might not be farfetched. But we should add that there are a lot of ‘ifs’ included in that scenario.

An offering looks all the more likely for Twitter because the field of potential acquirers has gotten significantly slimmer, since not many would-be acquirers have deep-enough pockets to pay for a premium on the startups’ already premium valuation. As we know from Twitter’s own embarrassing leak of some internal documents, Microsoft, Yahoo, Google and Facebook have all shown an interest in the startup at one point or another. But we’re not sure any of those companies would really be ready to do a 10-digit deal for a firm that’s still promising – rather than posting – financial results. Moreover, we wonder if any of the four would-be buyers even need Twitter. Yahoo and Microsoft seem focused on other parts of their business. Meanwhile, Google is hard at work on Google Wave, and Facebook appears to have moved on already with its much-cheaper acquisition of Twitter competitor FriendFeed in August.

Recent high-profile social networking valuations (based on last known valuation event)

In 2008, online social networking was the buzzword of choice. But as is the case with most tech bubbles, it imploded nearly as quickly as it ballooned. The year that started with a bang (Bebo’s record $850m sale to AOL in March and Plaxo’s sale to Comcast for an estimated $150m in May) ended with a whimper. Several smaller social-networking companies sold in fire sales, resulting in severe VC write-downs. And we expect this to carry on well into 2009.

Consider the case of business-focused Xing, which finished last year with a $4.1m tuck-in of New York City-based socialmedian. When we checked in with Xing before the holiday break, M&A and attractive valuations were the dominant themes. We fully expect the company to follow up on this with more acquisitions in 2009, particularly as social-networking competition goes global. Based in Germany, Xing has used M&A to expand geographically. In addition to its US deal last month, in 2007 Xing picked up Spanish competitors eConozco and Neurona. Furthermore, we understand that Xing was one of the active bidders for Plaxo, which would have represented a significant drive into the US market. On the flip side, US social-networking giants Facebook and LinkedIn are actively trying to expand across the Atlantic.

For Xing, there are literally dozens of US business-focused vertical social networks that would fit in with its expansion strategy. And the company has the resources to do deals. (It’s the only significant publicly traded social-networking company, plus it holds $61m in cash, no debt and is cash-flow positive on roughly $50m in trailing 12-month revenue.) Companies that we think might make a good match for Xing include Fast Pitch, APSense, Zerodegrees, and, dare we say, even Twitter.

Social networking M&A fizzles

This comes on the heels of other vertical social networking M&A. We believe this uptick in acquisitions, despite growing disinterest in traditional social networks, is a sign of a shift in focus to niche verticals. Venture capitalists have recognized this as well, and from what we hear a large shift in funding, especially among early-stage investors, is taking place. So what other vertical social networking sites are ripe for the picking?

LinkedIn, arguably the most successful among the verticals, springs to mind. The social networking site for professionals has been profitable for two years and is on track to make $100m this year from advertising and subscriptions. Founder Reid Hoffman has indicated to us in the past that he is open to offers if the price is right. Having recently attained the $1bn valuation we alluded to in the past, however, the site is now too expensive for most. And Hoffman seems content to wait for the struggling public markets to recover.

This is the exception to the rule, however; most other sites will be acquired. One such example is Flixster, a Shelfari-like social networking site for movie buffs. NewsCorp and Amazon could want to either eliminate an obvious and growing competitive threat or supplement their own Rotten Tomatoes and IMDB portals. With more than 40 million users, we estimate that Flixster could fetch more than $100m.

And it’s not just the obvious acquirers picking up these online sites. Mobile phone maker Nokia shelled out an estimated $30m for geo-social networker Plazes, while Hoover’s, primarily known as a business directory, bought into the Web 2.0 trend with its tiny $4.2m acquisition of Visible Path. Even Barry Diller went shopping in this market, with his IAC/InterActiveCorp’s purchase of Girlsense.com.

Despite the broad interest and appetite for social networking sites, we wonder if supply hasn’t outstripped demand. At last count, there were more than 130 networks of various stripes. With only two companies (Facebook and LinkedIn) likely to go public anytime soon, that leaves a slew of sites hoping to connect with buyers. Coming off a 1,200% increase in M&A from last year, we can only surmise that the number of deals – and, more important, the valuations handed out to the sites – is likely to come down.
