SAN FRANCISCO – Elon Musk, the new owner of Twitter, is throwing everything against the wall to make more money at the social media company.

Since closing his US$44 billion (S$62 billion) acquisition of Twitter last week, Musk and his advisers have discussed adding paid direct messages – which would let users send private messages to high-profile users – to the service, according to two people with knowledge of the matter and internal documents viewed by The New York Times.

They have also talked about adding “paywalled” videos, which would mean that certain videos could not be viewed unless users paid a fee, these people said.

And they have discussed reviving Vine, a onetime short-form video platform, which could attract a younger audience coveted by advertisers.

This week, Musk moved to make money from Twitter’s “blue check” verification programme, a method of making sure users are who they say they are.

The billionaire announced that the programme, which is currently free, will be rolled into the “Twitter Blue” subscription service, which will offer enhanced features for a monthly US$8 fee.

The frenzy of product development underlines the pressure that Musk, the world’s richest man, is under to deliver immediate results – and returns – on the technology industry’s largest leveraged buyout.

To finance his Twitter deal, he loaded the company with US$13 billion in debt, putting it on the hook to pay more than $1 billion annually in interest alone.

But last year Twitter had less than $1 billion in cash flow, meaning it generated less money than what it now owes its lenders annually. So, to make ends meet, Musk must boost Twitter’s revenue or cut costs – or do both.

Musk has already ordered job cuts across Twitter.

On Wednesday, a Twitter employee posted a link to a “severance calculations” document in a company Slack channel, noting that there was a “master list” that included the number 3,738, according to a copy of the message seen by the Times.

If that figure refers to people who could be laid off, and if the number holds, it will amount to about 50 per cent of Twitter’s 7,500-person workforce.

Interns were excluded from the list, according to the copy of the message.

Some of Musk’s advisers held a conference call on Wednesday evening to try to finalise the number of cuts, according to internal memos and calendar entries viewed by the Times.

Musk and representatives for Twitter did not respond to requests for comment. Bloomberg, The Washington Post, Axios and Jane Wong, an independent researcher, reported some details of the company’s plans earlier.

In an attempt to spin up new lines of business at Twitter, over the past week Musk and his advisers have dispatched product teams to brainstorm any and all ideas that could quickly bring in money, according to 10 current and former employees and internal documents discussing the matter. Three people who have met with Musk or his lieutenants said the focus was largely on how to increase revenue.

One product team is working on paid direct messaging, which appears to be focused on Very Important Tweeters, or VITs, on the network, said the two people with knowledge of the work and according to the internal documents.

According to the product mock-ups seen by the Times, users would be able to send private messages to their favourite celebrities for a nominal fee. A fee structure, which had not been set in stone, could be as little as a few dollars per direct message.

In early prototypes, a Twitter user was depicted asking musician Post Malone about his favourite records. Such paid messages could appear in a special area of the direct message inbox, and the celebrities would have to choose to receive them. Twitter would most likely take a cut of the fees, according to the documents.

The plans for paid direct messaging remain fluid, and there is no guarantee that the product will launch, the people with knowledge of the matter said.

Product teams are also working on “paywalled” videos, an idea similar to offerings from platforms like OnlyFans, which hosts content for creators in the adult content industry.

Under this plan, Twitter might ask users to pay a fee to watch a video, splitting the revenue with the creators who post the content, two people familiar with the project said.

Musk has also shown interest in Vine, the looping video app that was popular among young creators before Twitter shut it down in 2016.

He ran a Twitter poll on Sunday asking his followers whether or not he should bring it back.

He has commanded internal teams to examine the code to see if reviving it is possible, two people familiar with the conversations said.

Musk’s new Twitter Blue subscription service, which will give subscribers the check mark next to their username, is aiming to begin on Monday in the United States, Canada, Australia and New Zealand, according to internal documents seen by the Times.

The documents noted that there would be “an interim period where the check would be on both Blue subscribers accounts and previously verified users.”

Eventually, verified accounts that do not pay for Twitter Blue will lose the check marks. There were more than 418,000 verified accounts on Twitter at the end of October, one person with knowledge of the service said.

The documents also outlined plans for “government accounts to keep their Verified badge without paying for Blue”.

Some features for the subscription service already announced by Musk, including higher rankings for subscribers’ replies and the ability to upload longer videos, would not begin on Monday, according to the documents.

A European rollout was also planned, with the Twitter Blue team having worked to align the product with the European Union’s General Data Protection Regulation privacy law.

The Blue team was told to get the product ready for introduction by next week or face being fired.

Esther Crawford, one of the product managers, shared a photo of herself on Wednesday in a sleeping bag and eye mask on the floor of Twitter’s headquarters in San Francisco.

“When your team is pushing round the clock to make deadlines sometimes you #SleepWhereYouWork,” she tweeted. NYTIMES
