Twilio, the publicly-traded San Francisco communications tech company that powers text message notifications for companies like Netflix, Uber, and Coca-Cola Enterprises, closed trading on Wednesday at $34.59.

That’s a full 15.61% higher than at the opening bell, giving the company a market cap of $3.09 billion.

That spike comes after Benzinga reported that Twilio is deepening its partnership with Amazon Web Services (AWS), the $13 billion cloud computing arm of the Amazon retail empire, which helps software developers build and run their apps under a pay-as-you-go model.

In July 2016, Twilio and AWS inked a deal for the company to power the text messaging services it offers to software developers; now, that will reportedly expand to include voice messaging, as well. That means that software developers building with AWS would be able to easily use Twilio to have their apps send audio clips or make phone calls.

For Twilio, that would mean access to Amazon Web Services’ vast base of customers, which is what appears to be getting investors excited. Neither Twilio nor Amazon responded to a request for comment on the matter at the time of publication. However the two companies are known to be close. Twilio CEO Jeff Lawson gave a well-received keynote presentation at AWS’s huge customer conference in Las Vegas earlier this month, in which he hinted that the partnership would be expanded with new collaborations announced “soon.”

Still, Twilio has had a rough few months on the markets. When Twilio first debuted on the stock market at $15/share in June 2016, it took off like a rocketship, soaring up 90% in its first day of trading. But in late September, Twilio peaked at $68.97 and started sliding downwards — a slide that only accelerated when the company announced a secondary share sale.

For now, at least, Twilio is making up some lost ground: The stock is trading up around 1.5% in after-hours trading at the time of writing.

Here’s the chart of Twilio’s stock price from its June 2016 IPO to today:
