Salesforce rebuilt Slackbot with MCP. AI actions now happen in shared channels — not private DMs.

The shift from 1-on-1 AI to multiplayer AI is the real story of 2026. Teams that see what AI does will outperform teams that can't.

Every AI employee needs a computer.

Excited to be powering the computers behind Lindy Teammate.

The AI employee era is here. Congrats to the @getlindy team 🚀

[Pavitra Bhalla @pavitrabhalla]

@Altimor This is the direction I’ve been most excited about. AI employees are here.

And just like a human employee, an AI employee needs a computer.

Very cool to see @superserve_ai powering the computers behind every Lindy Teammate. Congrats to the @getlindy team on a huge launch.

Hot take: Schools banning AI are training students for a world that no longer exists.

The ones teaching verification? Training them for the one that does.

BetterDB Monitor v0.35.0 is now live 🚀

Someone reported a bug this morning that was throwing off what our MCP server was reporting back to AI agents. We tracked it down and shipped the fix same day.

Continuing the series from our last few releases, this update also adds five more detectors for Valkey/Redis hazards that can't be fixed in the engine itself:
- Config drift across replicas
- Stale hostname gossip
- Uncoordinated lagging promotions
- Ghost cluster membership
- A COMMANDLOG throughput regression

Hot take: The AI research tool you pick says more about your standards than your workflow.

Point tools find answers.
CoChat verifies them across models and ships a cited deliverable.

I launched Freestyle Remix today.

It's a voice assistant that lives next to your cursor.

Highlight any text, ask it a question out loud, and it researches online and rewrites the answer right where your cursor is.

The video is me fact-checking my lease agreement:

"Weeds & Wires" ranked #8 overall at @Gamedevjs Jam 2026 out of 495 entries.

A "Stacklands"-inspired farming automation sim built with #Phaser, with water systems, shifting market prices and a sardonic blue bird watching your every move 🌾🐦

"The real question isn't which tool has more features. It's which one you can trust with the work you have to defend."

Welcome to the Summer Catalyst cohort, @FreestyleVoice! Freestyle Voice is an open source voice dictation app that turns your speech into polished text 4x faster than typing.

[Matt Wang @mattt8p]

Charting into an EHR with voice dictation is so convenient. Watch me dictate a recent checkup.

Recent improvements to @FreestyleVoice has made dictating medical terms a lot more accurate. Freestyle can format what you say into SOAP notes and emails.

Impressive results from the @cochatai team: They just launched Deep Research Mode, and posted a normalized DRACO composite of 71.1 – ahead of every frontier model and every fusion configuration published to date!

This is the way now. Ramp, Stripe, CoinBase, Uber and now Sierra are running cloud agents across every company function. Sandboxes are core to running cloud agents.

Superserve sandboxes are fully open-source and we work with teams closely to help you deploy your own background agents. DM me if interested.

[Open Core Ventures @OpenCoreVenture]

Congrats to @betterdbhq on shipping an open, Valkey-native context layer for AI agents!

[BetterDB @betterdbhq]

shipped today: betterdb's open context layer for ai agents. three packages, one Valkey you run.

- agent memory (short-term + semantic long-term)
- semantic caching, multi-tier
- typed retrieval

typescript + python. self-tuning thresholds, otel/prometheus at every layer. no vendor lock-in.

new: provision a valkey with search straight from our cloud, zero setup. or self-host on the valkey you already run.

next week: a helm chart for one-command self-hosting, plus a detailed writeup with our longmemeval numbers and how we got them.

Exciting news from two of our portfolio companies: @superserve_ai has officially integrated with Anthropic's Claude Managed Agents, and @phaser_ is already putting it to work building a game development agent that creates fully playable arcade games autonomously.

[Superserve @superserve_ai]

We're excited to announce that we have partnered with @AnthropicAI to integrate Superserve sandboxes with Claude Managed Agents.

Thanks @phaser_, @getlindy, @mesa_dot_dev, and https://t.co/uGynKj4jJ8 for sharing your story with us!

Paid acquisition is like pouring gasoline on a fire. If you’re starting with real heat, it amplifies what’s already working. Pour it on damp wood, and it will flare up and burn out.

Paid acquisition is a multiplier, not a foundation, and most early-stage founders turn it on too soon.

WHAT A COOL EXPERIENCE! My @openclaw set up my Hermes agent from @NousResearch for me. Here's the guide it followed: https://t.co/knA5L9j4GM

The guide should work with any coding agent really

[Pavitra Bhalla @pavitrabhalla]

We are the *only* provider that lets you self-host sandboxes with VM level isolation, and unlimited session length (no 24 hour caps)

Thanks @tereza_tizkova for curating this list!
