Slack was built for humans. Now its tools talk, too.

In Slack's new platform, your calendars and doc apps can chat with each other.

A set of drag-and-drop building blocks in a customized workflow

Slack's new platform falls in line with head of Platform Steve Wood's projected vision at last year's Frontiers conference: the place users keep track of everything important happening in their company.

Slack wants to help your work tools talk with each other, and with you — all on Slack's new platform, unveiled at its annual Frontiers conference Tuesday.

Slack is the central hub of communication for at least 177,000 paying customers. With everyone working from home, it positioned itself as the ideal "digital headquarters" for companies, releasing tools like Slack Huddles to facilitate more connection. But work is about more than talking, and our work is spread across more apps than ever. "We want to make it so that Slack is highly customizable in the sense that you can get more of the business outcomes you need inside of Slack using the apps you have today," said Steve Wood, Slack's head of platform.

The new platform falls in line with Wood's projected vision at last year's Frontiers conference: the place users keep track of everything important happening in their company, compiling information from other tools and platforms. At a press briefing in preparation for this year's Frontiers, CEO Stewart Butterfield described the new platform as "a real perfect bridge" between "a solid, dependable professional structured system" and "looser, sometimes messier, more conversational actions."

"We have rebuilt the platform, and that's not hyperbole," Wood said. Slack's platform already allowed developers to build their own apps and workflows within Slack itself. But for the most part, the apps were siloed. For example, Outlook and Google Calendar apps couldn't coordinate to schedule a meeting through Slack. On Slack's new platform, developers can create apps that talk to each other.

Eventually, Slack users will be able to look at these apps and fit them together into customized workflows for their company. They'll build workflows with no code, simply dragging and dropping the apps together. Slack already has a workflow builder, but not for complex or highly specific processes. You can set up a daily check-in reminder in a channel, but you can't, for example, create a multistep sales approval process that might trigger a "request signature" notification in DocuSign. What will these workflows look like? It's all a bit nebulous right now, as Slack wants to wait and see what developers create in private beta.

"We're watching to see what our developer ecosystem does, and then we'll work on the builder for normal people," Wood said, noting that over a million developers use the platform. "The approach we're taking with that is we want you to find a useful workflow that works for you."

Apps communicating with each other is also a big deal for Slack Connect, which allows users to talk to people outside their companies. The same building blocks and workflows can be used in the Connect channel as well. "We see this as being a very powerful way for different organizations that have different tools to to come together," said Ilan Frank, VP of Product.

Third-party integrations continue to be important to Slack, as the platform wants to notify users of what happens in outside apps. Wood's team is working on allowing people to subscribe to third-party app notifications within Slack. Salesforce, Slack's parent company, is a key integration within Slack. Smartsheet, the tracking tool for managers, also integrates with Slack and has helped build inter-tool notifications. Cynthia Tee, Smartsheet's senior VP of Engineering, said "people should work where they want to work." If Smartsheet users want to stay in Slack, so be it.

"It's all about keeping you in the place you want to be when you want to collaborate with folks over Smartsheet," Tee said. "It enables you to not only view that document, but say, 'Hey, I want to be notified whenever something happens in this document.'"

People often complain about the noise within Slack; constant pinging or unread messages in channels can be overwhelming. Introducing more notifications into that environment could make that issue worse. But Wood argued third-party notifications can be powerful, especially with customized workflows around them.

"The world isn't getting any slower and it's not getting less noisy anytime soon," Wood said. "You have the tools to escalate the things that you want to escalate and to silence the things you don't care about."


The minerals we need to save the planet are getting way too expensive

Supply chain problems and rising demand have sent prices spiraling upward for the minerals and metals essential for the clean energy transition.

The newest source of the alarm bells echoing throughout the renewables industry? Spiking critical mineral and metal prices.

According to a new report from the International Energy Agency, a maelstrom of rising demand and tattered supply chains have caused prices for the materials needed for clean energy technologies to soar in the last year. And this increase has only accelerated since 2022 began.

Why the digital transformation of industries is creating a more sustainable future

Qualcomm’s chief sustainability officer Angela Baker on how companies can view going “digital” as a way not only toward growth, as laid out in a recent report, but also toward establishing and meeting environmental, social and governance goals.

Three letters dominate business practice at present: ESG, or environmental, social and governance goals. The number of mentions of the environment in financial earnings has doubled in the last five years, according to GlobalData: 600,000 companies mentioned the term in their annual or quarterly results last year.

But meeting those ESG goals can be a challenge — one that businesses can’t and shouldn’t take lightly. Ahead of an exclusive fireside chat at Davos, Angela Baker, chief sustainability officer at Qualcomm, sat down with Protocol to speak about how best to achieve those targets and how Qualcomm thinks about its own sustainability strategy, net zero commitment, other ESG targets and more.

The 911 system is outdated. Updating it to the cloud is risky.

Unlike tech companies, emergency services departments can’t afford to make mistakes when migrating to the cloud. Integrating new software in an industry where there’s no margin for error is risky, and sometimes deadly.

In an industry where seconds can mean the difference between life and death, many public safety departments are hesitant to take risks on new cloud-based technologies.

Dialing 911 could be the most important phone call you will ever make. But what happens when the software that’s supposed to deliver that call fails you? It may seem simple, but the technology behind a call for help is complicated, and when it fails, deadly.

The infrastructure supporting emergency contact centers is one of the most critical assets for any city, town or local government. But just as the pandemic exposed the creaky tech infrastructure that runs local governments, in many cases the technology in those call centers is outdated and hasn’t been touched for decades.

Work expands to fill the time – but only if you let it

The former Todoist productivity expert drops time-blocking tips, lofi beats playlists for concentrating and other knowledge bombs.

“I do hope the productivity space as a whole is more intentional about pushing narratives that are about life versus just work.”

Doist, the company behind to-do-list app Todoist and messaging app Twist, has pushed remote and asynchronous work for years. Adegbuyi’s job was to translate these ideas to the masses.

“We were thinking about asynchronous communication from a work point of view, of like: What is most effective for doing ambitious and awesome work, and also, what is most advantageous for living a life that feels balanced?” Adegbuyi said.
