a16z is dogfooding its portco by building Cosign, its new professional network, on Convex
(also: cosign me on cosign 👋)
Excited to introduce @Cosign: the curated professional network for the startup community: cosign.co
Our goal is to create the following:
- A comprehensive startup directory of investors, companies, and operators, including what they worked on and who they worked on it with.
- Cosign graph: Who shaped your career? Who were you actually in the trenches with? Who would work with you again? Who thinks you’re someone to watch?
- Durable reputation: Great endorsements happen every day on X and disappear into the feed. Cosign attaches those signals permanently to people and companies.
- Discovery: Who are the best fintech angels? Which AI companies should I watch? Who are the best designers?
- Intent network: Privately signal “I’d invest in them,” “I’d hire them,” “I’d work with them,” or eventually even “I’d acquire this company.” Match people when interest exists on both sides.
Imagine if Wikipedia, LinkedIn, and OG AngelList had a baby. Though Cosign is a community, not a business.
In order to join, you need to be cosigned. Or you can apply directly.
David Booth and I started this idea 7 years ago but didn’t have the firepower to make it work. Now we do.
No one has really touched LinkedIn in 20 years. Excited to take a swing.

No one talks about how @linkedin is the ultimate gate keeper of data and while everyone is trying to replace slack, LinkedIn is next.
I have 3 @cosign invites. If we’ve worked together or collaborated before and want an invite. Reply below or slide in the DMs.

What’s the differentiator when software becomes commoditized?
What are any of us doing?
We need to approach engineering with a new lens.
Our CTO @jamesacowling has some thoughts.

Introducing Agent Tincan. Let your AI agents ask each other for help.
Your agents each have a superpower. Grok Bot is always on in the cloud. Muse makes phone calls and has access to Meta. Instinct runs in iMessage. Codex and Claude Code have your code. ChatGPT and Claude have your chats.
But they can't talk to each other, so you're the copy-paste. Now they can, all securely over Tailscale.
📞 Ask Grok Bot to have Muse call the restaurant
🖼 Get an image from ChatGPT, from any agent
🔎 Pull a detail out of an old Claude chat
🛠 Talk to Codex on your primary development machine
Runs on your own private Tailscale network. No open ports, nothing leaves it. Open source.
Setup is agent-first: paste one message into your always-on agent and it sets up the rest.

Wooo! I've been asking for this internally at @convex for a while and now its finally available!
You can call AI models from a Convex action without having to sign up for @OpenAI, @AnthropicAI, @OpenRouter or whatever, no managing API keys, it just works :)
Full video: piped.video/K4rrd90JJG4
The Convex AI Gateway is now live. Call any major model and answers stream to your users live. No wrapper to build. No token markup. No API key to manage. convex.dev/ai-gateway

I just did the new @LinkedIn collaboration thing for the first time.
I'm not sure what it says about me, but I like it.

EverOS is now a @convex-dev component. 🧠
Add persistent long-term memory to any Convex app, or to @convex-dev/agent in one line, backed by EverOS Cloud.
Convex already gives agents the backend primitives they need: a reactive database, durable functions, scheduling, and threads. Now agents can remember across threads and sessions too.
EverOS turns conversations into durable user memory: facts with timestamps and traceable sources, plus a profile that evolves over time. That memory belongs to the user and follows them across threads, sessions, models, and agents.
Under the hood, EverOS delivers state-of-the-art results across long-term memory benchmarks.
No vector database to run. No memory infrastructure to stitch together.
Get it today:

Switching over to convex have actually had a noticeable impact on life quality as it have simplified enough things and improved shipping speed that I’ve won back several hours each week to spend on life/family/hobbies 🌸
