AI startup Cresta launches from stealth with millions from Greylock and a16z

As Silicon Valley’s entrepreneurs cluster around the worldview that artificial intelligence is poised to change how we work, investors are deciding which use cases make the most sense to pump money into right now. One focus has been the relentless communication between companies and customer that takes place at call centers.

Call center tech has spawned dozens if not hundreds of AI startups, many of which have focused on automating services and using robotic voices to point customers somewhere they can spend money. There has been a lot of progress, but not all of those products have delivered. Cresta is more focused on using AI suggestions to help human contact center workers make the most of an individual call or chat session and lean on what’s worked well for past interactions that were deemed successful.

“I think that there will always be very basic boring stuff that can be automated like frequently asked questions and ‘Oh, what’s the status of my order?’” CEO Zayd Enam says. “But there’s always the role of the person that’s building the relationship between the company and the customer, and that’s a really strategic role for companies in the modern age.”

Udacity co-founder Sebastian Thrun is the startup’s board chairman and is listed as a co-founder. Enam met Thrun during his PhD research at Stanford focused on workplace productivity. Cresta is launching from stealth and announcing that they’ve raised $21 million in funding from investors including Greylock Partners, Andreessen Horowitz. The company recently closed a $15 million Series A round.

Cresta wants to use AI to school customer service workers and salespeople on how to close the deal.

There’s quite a lot of turnover in contact center jobs and that can leave companies reticent to spend a ton of time investing in each employee’s training. Naturally, there are some inherent issues where the workers interacting with an individual customer might not have the experience necessary to suggest a solution that they might if they had more experience. In terms of live feedback, for many, fumbling through paper scripts at their desk can be about as good as it gets. Cresta is hoping that by tapping improvements in natural language processing, their software can help alleviate some stress for contact center workers and help them move conversations in the direction of selling something else for their company.

Cresta is entering a field where there’s already quite a bit of interest from established software giants. Salesforce, Google and Twilio all operate AI-driven products for contact centers. Even with substantial competition, Enam believes Cresta’s team of 30 can offer its customers a lot more individual attention.

“We’re one of the few technical teams where we’re just obsessed with the customer, to the point where it’s normal for people on our team to fly to the customer and live by a call center in an Airbnb for a week,” Enam said. “When Greylock led the Series A, they had heard that and said that’s what gave them so much conviction that we were the team to solve the problem.”

Sun Microsystems co-founder Andy Bechtolsheim, Mark Leslie and Vivi Nevo are also investors in Cresta.

Alphabet earnings show Google Cloud on $10B run rate

Today after the bell, Alphabet reported its fourth-quarter and full-year financial results. The company’s revenue grew from $39.3 billion in 2018 to $46.1 billion in 2019. The firm’s net income also expanded from $8.9 billion to $10.7 billion over the same time frame.

The figures, when compared to expectations, were mixed. Alphabet beat analyst estimates on profit, but missed on revenue. Shares of the company are off around 4% in after-hours trading, following its disclosure.

Why do we care?

The company’s reported Q4 and full-year 2019 results are notable for several reasons. First, Alphabet broke out the value of YouTube’s advertising empire. And, the company disclosed discrete “Google Cloudâ€� revenues. Both are new.

YouTube’s advertising heft was made clear today, with the video platform bringing in $15.1 billion in 2019 revenue, up from $11.2 billion in 2018.

The firm’s new “Google Cloud� line item appears to include all of the company’s cloud computing efforts. YouTube’s advertising haul will grab the most headlines, but the cloud revenue figure is what we’d like to drill into.

Cloud, Google-style

Google announced an impressive $2.6 billion round for all cloud revenue, which includes G Suite, the enterprise version of GMail/Docs/Drive/Hangouts and Google’s cloud infrastructure revenue. At $2.61 billion, that puts it on a run rate over $10 billion. In the year-ago Q4, the company’s Cloud revenue came to just $1.71 billion, a run rate of $6.84 billion.

Google’s Cloud run-rate, then, grew by 53.6% in the last year.

In February of 2018, then-Google Cloud CEO Diane Greene was happy to report $1 billion quarterly revenue for the group. Last July, the company’s Cloud revenue crossed $2 billion for that quarter, putting on an $8 billion run rate, double the previous report.

Former Oracle executive Thomas Kurian took over after Greene stepped down last year, and he brought on a number of industry veterans from Oracle and SAP to help sell Google Cloud to the enterprise. So far the results are certainly encouraging in a short amount of time.

In comparison

While Google is making some gains in the cloud, its chief competitors have been doing well at the same time.

To pick one example, Amazon’s cloud revenue totaled just under $10 billion in the same calendar quarter. In a direct comparison, Google is far smaller, but the search giant is working to make up ground and the results appear encouraging. It’s worth noting that Amazon’s comparable cloud figures are more focused on infrastructure than Google’s, which includes SaaS revenue, as well.

Turning to Microsoft, it reported a combined cloud revenue, which includes SaaS (Office 365, Dynamics, etc.) and cloud computing (Azure), of $12.5 billion for the quarter. All of this shows that while Google still has a long way to grow to match its rivals for scale, it’s at least picking up the pace.

Twitter suspends ‘large network’ of fake accounts used to match phone numbers to users

Twitter announced today that over the holidays it identified and shut down “a large network of fake accounts,” as well as many others “located in a wide range of countries,” collectively abusing a feature that let them match phone numbers to user accounts.

TechCrunch previously reported this same issue on December 24, which is also the day Twitter says that it “became aware” that the abuse was taking place. Security researcher Ibrahim Balic found that a bug in Twitter’s Android app let him submit millions of phone numbers through an official API, which returned any associated user account.

The feature is intended, if you have enabled it, to let friends who have your number look up your Twitter handle. But obviously submitting millions of numbers goes “beyond its intended use case.”

If you had turned this feature off, you weren’t affected by this bug. Fortunately for users in the EU this was opt-in there. But for the rest of the world it’s opt-out — so if you had a phone number associated with your account, you may have been affected.

Furthermore, the phone numbers include those provided for purposes of two-factor authentication, so those outside the EU may have been vulnerable to this exploit without realizing it.

It seems that after Twitter was alerted to the issue and shut down the original network (presumably Balic’s), its investigators identified many more accounts that were exploiting this flaw, though a representative declined to provide a number or estimate.

“We observed a particularly high volume of requests coming from individual IP addresses located within Iran, Israel, and Malaysia,” wrote the company in a security bulletin. “It is possible that some of these IP addresses may have ties to state-sponsored actors,” the post continued.

This suspicion was justified by the observation of unrestricted access to Twitter from the IPs in Iran, where the platform is blocked from general access — suggesting government involvement. Belic, when contacted by TechCrunch, said that his work was not state-sponsored in any way.

Any account suspected of abusing the feature was suspended, and the API itself has been modified to prevent any further exploitation of this type. I’ve asked the company how many accounts were suspended and will update this post if I hear back.

Twitter has had numerous incidents where it exposed or leaked user data over the last year. In addition to sharing rather too much data with its ad partners, the company admitted it used phone numbers used for two-factor authentication to serve targeted ads.
