The Oracle-NetSuite deal may mean the sky's the limit for more big tech mergers.

Stop me if you’ve heard this before: The tech industry is headed for a potentially huge round of mergers and acquisitions.

These sorts of deals have been going on for a while. But what is new now is that Oracle orcl announced its planned $9.4 billion acquisition of NetSuite just six weeks after Microsoft disclosed its $22.6 billion buyout of LinkedIn lnkd .

That demonstrates is no deal is too big anymore, according to Sunil Dhaliwal, general partner with venture capital firm Amplify Partners.

Before this last spate of mega-purchases, the tech landscape was littered with smaller but still impressive acquisitions. It was a billion or two here and a billion or two there, but now we’re talking real money.

That could mean that even very, very large players—say Salesforce crm and Workday wday —are getting serious looks, according to venture capital execs, who it should be noted could have a vested interest in such deals. However, that does not make what they’re saying untrue.

Salesforce crm , with an enterprise value of about $55.8 billion, would be extremely expensive. Last year, the company reportedly rejected a $55 billion offer from Microsoft. Salesforce chief executive Marc Benioff reportedly wanted $75 billion, and Microsoft msft balked.

Maybe that asking price would sail through this summer—or maybe Salesforce will be a buyer, instead of a seller.

Software-as-a-Service (SaaS) companies like Salesforce, which deliver software over the Internet, are of particular interest because that sales delivery model is becoming more successful with corporate customers. Neeraj Agrawal, a general partner with Battery Ventures, estimates that SaaS—as hot as it’s been—still represents just 15% of current software market, but he suggests that won’t be the case for long.

“We hit the inflection point now where chief information officers instead of saying “why buy cloud?’ are saying ‘why not cloud?'” he tells Fortune, predicting SaaS to comprise 60% to 70% of the market in the not-too-distant future.

There are two possible sets of buyers. First, there are the big legacy software players—Microsoft, Oracle, and IBM ibm —that need to bulk up their SaaS offerings. They buy other software companies to acquire more customers, but also to offer a broader array of software services for recurring revenue.

Second are the private equity (PE) companies, which suddenly seem to be willing to write bigger checks than in the past.

“PE firms have come to the same understanding of the power of the SaaS model so where they used to pay five to six times EBITDA, they’re now willing to pay five or six times revenue,” says Agrawal. EBITDA stands for earnings before interest tax depreciation and amortization, which is a far smaller number than overall revenue. In plain terms, this means that PE companies are now willing to cough up bigger bucks for tech entities.

Examples of recent PE purchases include Vista Equity Partners buying Ping Identity for $600 million and Thoma Bravo’s acquiring Qlik for $3 billion. Both deals happened in June. In May, Vista bought Marketo, a publicly-held marketing automation software company, for $1.79 billion.

But it’s not just SaaS companies. “Anything in enterprise tech that’s not locked down is going to private equity,” observes Dhaliwal. As if on cue on Friday, The Information reported that several PE firms—including KKR, Apollo Global Management ,and the Carlyle Group—are taking a look at Hewlett Packard Enterprise hpe .

Nearly every company now has to be considered a buy opportunity, including public ones like Atlassian team , Box box , ServiceNow servicenow , as well as private startups like and Slack, says VC execs.

Potential buyers outside the PE realm include not just Microsoft and Oracle but also Google goog , which is trying to build up its enterprise cloud business, and potentially even Amazon amzn Web Services, which to date has not been an acquirer of big properties.

But things change.
