Don’t Build Your Company’s Brain Inside Slack. You Will Pay For It.

April 20, 2026

I spent years as CIO of a publicly traded company before I started Roam. In that time I watched a specific pattern play out again and again: a team adopts Slack for chat, and over the next few years quietly migrates many of its decisions, customer insights, and pieces of tribal knowledge into its channels and DMs. Not everything. But enough to produce the feeling that our company is running on Slack.

That is the moment you should be panicking. Because two things are true about the place you just put much of your company’s brain, and both of them are going to cost you: it only contains a fraction of how your company actually thinks, and the vendor that owns it is about to find out exactly how much you’ll pay to keep it.

Chat Is One Slice Of How Work Happens. Not All Of It.

The counter-argument, which I’ve heard from every Slack evangelist over the last two years, is that AI is going to fix all of this. Give it another six months and your Slack archive becomes a searchable, summarizable corporate memory. I actually agree AI will be extraordinary at organizing the chat transcript. That’s not the problem.

The problem is that the chat transcript is a small slice of how a company actually thinks, and it happens to be the least valuable slice. Decisions get made in meetings. Customer context gets created on sales calls. Strategy gets reframed in all-hands. Architecture gets sketched on whiteboards. Tradeoffs get explained in screen recordings. Slack sees the text residue of these events, if anyone bothers to write any of it down — which they usually don’t, because they just had the meeting.

So when you point an AI at your Slack archive and ask it what your company thinks about something, you get back a fluent summary of your company’s group chat. Not your company’s thinking. And that is worse than useless — it dresses up a fragmentary picture in the confident prose of a complete one. You get answers that sound authoritative and are missing the context that actually mattered.

Slack didn’t do this to you. You did this to yourself, because Slack was the easiest place to type something, and you slowly convinced yourself that what gets typed is what gets thought. That’s what Salesforce is counting on.

Then The Bill Comes Due

Slack has been owned by Salesforce since 2020. Salesforce did not pay $27 billion for a chat app out of sentimentality. They paid it because once a tool becomes the place your company thinks, you cannot leave. And when you cannot leave, the price goes up.

This is not a prediction. It is Salesforce’s playbook, run on every product they’ve ever owned: land cheap, expand into every workflow, wait until switching costs are unbearable, then move the pricing up and the features you need into higher tiers. Slack has been quietly walking this path for years — per-seat increases, AI gated to Business+, message history limits, admin controls parceled across tiers. The more valuable Slack has become to your company, the less leverage you have to push back. Salesforce’s sales team knows the number of channels you have, the integrations you’ve built, and the size of your archive. That is the number your renewal will be priced against. Not a penny less.

The Real Cost Is What You Can’t Measure

Buyers love to calculate the per-seat price. The actual cost of putting your company’s brain inside Slack is harder to spreadsheet. It is the cost of every AI-generated answer that sounds right and is missing the meeting where the opposite decision was made. Every new hire who onboards from a chat archive and comes out confidently wrong. Every strategic debate re-litigated because the version that got written down wasn’t the version that got decided. And eventually, a renewal conversation where the vendor knows you have nowhere to go.

A Different Approach

I didn’t just complain about this. I built differently.

At Roam, we built a virtual office — a single place where your team meets, presents, records, and chats. The decisions, the context, the recordings, and the text residue all end up in the same place because they all happened in the same place. That is what makes an AI layer actually worth something: when your assistant can see the meeting where the decision was made and the chat thread that followed, it can answer how your company actually thinks, not just how it types.

One plan, one price, every feature included, and we only bill for members who actually log in. The details are boring on purpose. The point is the philosophy: your company’s brain is too important to assemble from a dozen vendors’ scraps, and too important to rent from any one vendor whose business model depends on you being unable to leave.

The Bottom Line

Use chat for chat. Don’t let it become your wiki, your decision log, and your institutional memory all at once. And if you are going to put your company’s brain somewhere, put it somewhere that isn’t owned by a vendor whose entire corporate DNA is built around squeezing you the moment you depend on them.

Because Salesforce is very good at what it does. And what it does, eventually, is present you with the bill.
