Good Morning, Builders.

Today’s brief covers trade tensions, AI monetization, platform rivalries, and market shakeups, plus a founder-focused Tech & Tools insight: how to audit your team’s communication stack and pick the right tools. Let’s get to work.


I. Here’s What’s Inside

  • The Headlines:
    OpenAI hits $20B in annual revenue, Trump threatens French wine tariffs, TikTok tightens age checks in Europe, Wingify & AB Tasty merge for AI-ready A/B testing, and Amazon calls its $475M Saks stake worthless after Chapter 11.

  • Tech & Tools:
    Slack, ClickUp, Teams, Mattermost, Monday.com—each works for different teams. Today we break down the trade-offs, pricing, structure, and AI integrations so you can optimize your communication stack, reduce costs, and actually get work done without losing context or trust.

II. The Headlines

1. $20B and Counting for OpenAI

OpenAI’s CFO says annualized revenue topped $20B in 2025. Growth has been driven by a massive jump in computing power and record user activity. The company is leaning into ads, agents, and workflow automation while keeping its balance sheet light through partnerships. Next up is practical AI adoption in health, science, and enterprise, and a first OpenAI device slated for late 2026. AI scale is officially big-business scale. (Reuters)

2. Trump Targets French Wine With Tariff Threat

Trump is escalating trade threats, this time targeting French wine and champagne with a proposed 200% tariff. Trump also doubled down on plans to take control of Greenland, brushing off European resistance and hinting at more tariffs if allies push back. Markets are watching closely as trade policy, geopolitics, and off-the-cuff diplomacy collide… again. (CNBC)

3. TikTok Tightens Age Checks as Europe Eyes Tougher Rules

TikTok is rolling out stronger age-detection tech across Europe to crack down on under-13 users. The move comes as multiple EU countries consider raising minimum social media age limits. At the same time, TikTok is making its economic case, claiming €31B in EU economic impact in 2025 and support for 6.5M businesses. Regulation is looming, but TikTok wants credit for both safety and scale. (Social Media Today)

4. A/B Testing Consolidates as Wingif & AB Tasty Combine

Private equity firm Everstone Capital is combining India’s Wingify and France’s AB Tasty to create a global digital experience optimization platform with over $100M in annual revenue. The move reflects growing consolidation in A/B testing and personalization as enterprises push for AI-ready, all-in-one platforms. No layoffs are planned, just heavier investment in AI-driven capabilities ahead. (TechCrunch)

5. Amazon Says $475M Saks Stake is ‘Worthless’ 

Amazon is fighting Saks Global in court, arguing its $475M investment tied to Saks’ Neiman Marcus acquisition is now worthless following Saks’ Chapter 11 filing. Originally, the deal included a “Saks at Amazon” storefront and guaranteed referral fees. Amazon warns it may seek stronger remedies, including a court-appointed trustee, as Saks begins drawing on $1.75B in new financing to avoid immediate liquidation. (Complex)

III. The Slack Bill That Made Everyone Do a Double Take

The founder of BloomTech, formerly Lambda School, shared a Slack invoice on ‘X’ North of $300,000 for a single quarter.

The bill has since made its rounds on LinkedIn and Reddit, with most people (myself included) stunned at the cost for just one quarter.

And this for sure prompted a lot of founders to cautiously open their own billing dashboards.

Because while that number is extreme, the feeling isn’t.

Almost every growing team hits a moment where Slack and tools like it start feeling like a tax. Headcount goes up, contractors stick around, channels multiply, and suddenly the bill is… uncomfortable.

This isn’t a “Slack is bad” take. 

Slack is still one of the best communication products ever built, and my team uses it daily.

But, I’ve got to ask, “Is Slack still the best tool for how your team actually works today or just the default you never revisited?”

Especially now that so many teams are remote, hybrid, or fully async.

So let’s talk alternatives, tradeoffs, and where each tool actually makes sense.

Best for: Remote teams that need to move fast and don’t want to think too hard about tooling.

Slack’s biggest strength is still the obvious one: it’s easy.

It’s intuitive, straightforward, and new hires don’t need onboarding to use it. That alone explains why it’s everywhere.

Everything in Slack is organized around chat, which is a double-edged sword.

Chat is great for speed. But it’s terrible as a long-term system of record.

Decisions get made quickly, but they also get buried. Then, a few months down the line, you’re scrolling through channels trying to remember why something was decided in the first place.

Our team operates fully remotely, so having a reliable communication tool isn’t optional. 

We use Slack daily for quick huddles, screen sharing, file sharing, and general coordination. For that, it does exactly what it needs to do.

What Slack does well

  • Extremely easy to use (no learning curve)

  • Fast communication for remote teams

  • Reliable huddles, screen sharing, and file sharing

  • Strong mobile app for staying lightly connected on the go (one feature I love, it helps keep me connected to my team while my wife and I are exploring all the U.S. National Parks over the weekend). 

  • Integrates with almost everything

Where Slack starts to break down

  • Pricing is per seat, so costs climb fast as your team grows

  • Old users rarely get removed, which can inflate your bill

  • Chat-based organization means decisions and context get lost

  • No end-to-end encryption, which can matter depending on what you share

If you’re paying more than you’d like for Slack, a quick clean-up/audit can cut down your bill. Or you can just keep reading and check out some of the alternatives. 

Best for: Teams that want fewer tools, more structure, and don’t mind a learning curve.

Some of my team and I recently migrated parts of our workflow to ClickUp for a few external projects.

And, the simplest way to describe ClickUp is this: It’s Clockify + Notion + Slack rolled into one platform.

And for the most part, it actually lives up to the “all-in-one” promise.

Where ClickUp really shines is organization. 

Tasks, docs, timelines, time tracking, dashboards, everything is in one place, which cuts down a lot of context switching.

One feature my team loves more than expected: AI Agents.

We uploaded some of our internal playbooks and processes into ClickUp. 

Now, when I ask a question about a deadline or how something should be done, the AI often answers before a teammate even sees the message. 

It’s surprisingly useful, especially for repeat questions and standard workflows.

What ClickUp does well

  • True all-in-one workspace (tasks, docs, chat, time tracking)

  • Excellent for structured project management

  • Built-in time tracking (great for billing + understanding task effort)

  • Whiteboards, dashboards, calendars, Gantt charts, lists

  • Strong AI Agents for process and knowledge recall

  • Reduces the need for multiple tools

Where ClickUp can get frustrating

  • There is a learning curve

  • Not as instantly intuitive as Slack

  • Easy to overbuild workflows if you’re not disciplined

  • Customization can become complexity

  • AI Agents and add ons are great, but can get pricey

ClickUp works best when you actually want structure.

If your team just needs fast communication, it can feel like overkill.

But if you’re tired of juggling five tools and losing context across them, ClickUp can replace a surprising amount of your stack.

Best for: Companies already deep in Microsoft 365.

If your company already runs on Microsoft (Outlook, Word, Excel, SharePoint) Teams usually comes “free” with your licenses. And for a lot of finance and ops teams, that alone makes the decision.

We’ve worked with plenty of clients who use Teams simply because it was already there. 

Now, where Teams actually works well is in scheduled, structured communication:

  • Calendar-native meetings

  • Internal calls

  • Formal collaboration across departments

It feels familiar to anyone who’s spent time in a corporate environment.

What Teams does well

  • Tight integration with Outlook and Microsoft calendars

  • Solid video calls and screen sharing

  • Familiar interface for corporate teams

  • Included with many Microsoft 365 plans (big cost lever)

Where Teams struggles

  • Clunky UX compared to Slack

  • Chat feels slower and less intuitive

  • Harder to build real-time momentum in conversations

  • This would not be my #1 rec for creative, startup, or sales teams

For fast-moving, async-heavy teams, Teams doesn’t feel like the best option, but if you're a Microsoft 365 fanatic, then this should probably be your top pick. 

Best for: Engineering-heavy teams that care deeply about security and control.

Mattermost is basically the anti-Slack.

It’s built for teams that want:

  • Full control over their data

  • Predictable pricing

  • The option to self-host

You’ll see Mattermost used a lot in:

  • Engineering orgs

  • DevOps teams

  • Companies with strict compliance or security requirements

If Slack feels too SaaS-y or risky from a data standpoint, Mattermost is usually the alternative people evaluate.

What Mattermost does well

  • Open-source options

  • Self-hosted deployments

  • Strong security and compliance controls

  • Predictable pricing at scale

  • Integrates well with GitHub and dev workflows

Where Mattermost falls short

  • UI isn’t as polished

  • Less intuitive for non-technical users

  • Onboarding can be slower

  • Feels utilitarian

Mattermost is a great tool if your team already uses GitHub and Jira and thinks in systems.

But for sales, marketing, or ops teams, it can feel heavy and challenging fast.

Tech teams, this one is for you. 


Best for: Teams that want ClickUp-style structure with a slightly lighter learning curve.

Monday.com is one of ClickUp’s closest rivals. 

It’s built around visual workflows (Kanban boards, timelines, and dashboards) but with a cleaner, more approachable interface. 

Where ClickUp can feel overwhelming if overbuilt, Monday.com often hits a sweet spot for teams that want structure without drowning in options.

What Monday.com does well

  • Visual, highly customizable boards and dashboards

  • Easier learning curve than ClickUp

  • Integrates with Slack, Teams, and many other tools

  • Good automation options to reduce repetitive work

  • Strong collaboration for cross-functional teams

Where Monday.com can get frustrating

  • Can feel “light” for heavy project management needs (ClickUp still wins there)

  • Some advanced features require higher-tier plans

  • Pricing scales with users and features

10-Second Insight Recap

Slack: Fast, intuitive chat. Great for speed, not great for long-term context.

ClickUp: All-in-one workflow powerhouse. Deep structure, but can be overwhelming.

Monday.com: Visual, structured, lighter learning curve than ClickUp, best for cross-functional teams.

Teams: Works if you’re deep in Microsoft 365; slow for async-heavy or creative teams.

Mattermost: Security-first, self-hosted option for dev-heavy teams; not intuitive for non-tech users.

At the end of the day, there’s no one-size-fits-all communication tool. 

The best tool is the one that actually fits how your team works today. 

Test a few, take advantage of free trials, see what clicks, and then commit, your future self (and your sanity) will thank you.
