Intelligence needs a user interface. At @designerfund, we're backing @trajectorylabs alongside Sequoia and NVIDIA to build it.
We believe continual learning is one of the most interesting design challenges in AI.
We've spent decades building intuitive tools for editing images, documents, and software, but not model behavior ↓
Imagine if everyone had the tools to shape intelligence itself. That day is today.
Today we launch the Trajectory platform - the easiest and most intuitive tool to post-train models of your own. The foundation for continual learning.
With just a few agent prompts, you get access to a full creative suite to train, eval, and deploy trillion parameter models.
On top of that, we believe in a future where you don’t just shape your model once, it also keeps learning on its own from the world around it.
We’re releasing two research previews.
1. Continual grading scales your taste, so your model learns what good looks like from far more than you could ever grade by hand.
2. GS1, a new algorithm that lets models learn directly from what they do in production.
We’ve now raised 60M, with a new round led by @Sequoia at a 300M valuation to democratize the most powerful technology of today - training models - so that the lawyers, doctors, and engineers of the world can own their own intelligence.
You know what good looks like, now go build it. Own your own value function with Trajectory.
Trajectory makes post-training more accessible, giving the experts on a team, not just AI researchers, an intuitive platform to train models, evaluate results, and ship improvements using feedback from real product usage.
We’re proud to back @rronak_, @michaelelabd, @QuantumArjun, and the entire @trajectorylabs team.

The team is looking to connect with exceptional designers and design engineers who are excited about these kinds of problems, particularly those who enjoy complex systems and prototyping new interactions.

We know we're right because customers like @ShawnFarsai at @harvey are the best creative teams at the best AI companies in the world.
These are the people who understand deeply what this technology can do.
This is who we're building @airhq for.

Announcing @InputSystems. A new way to email ✨
It handles your messages and the work that follows.

human review is still the bottleneck for most AI migrations today. so we designed an agent graph around the needs of the reviewer…
and migrated our entire design system (54k lines, 794 files) in 2 weeks with no major regressions. here's how we did it ambrook.com/engineering/ai/m…

Discussing Design as Edge in this era of technology at Gem Home in SoHo, NYC
Massive thank you to our @designerfund partners in this event: @BessemerVP and @mercury
Let us know if you’d like to be on the radar for our next.
Another big step toward closing the gap between designing and building. Congrats to the @framer team on launching Framer MCP!
The Framer MCP is here. Design, build, and update your site with AI tools like ChatGPT, Claude, Cursor, and Grok. Without giving up Framer’s flexibility, reliability, and control. framer.link/mcp

This is the way. MCP for speed to create and update. @framer platform for collaboration and control. Best of all worlds.

Ha - 1. great way to get twitter engagement and 2. list is already improving - @ambrook, @paper, @interfere_, @framer should be higher. Love having 3 @designerfund companies in the top 10 @linear, @stripe, @NotionHQ ;)
Travel planning is getting a serious upgrade.
Congrats to @FDavidsonT and team on launching @OdessiaTravel today! From researching and ranking hundreds of thousands of hotels to finding better rates, perks, and smarter itineraries, Odessia brings a new level of thoughtfulness to planning travel.
We're excited to see it out in the world: odessia.com

Announcing the beta release of the Pi API. We’ve partnered with companies across diverse industries to adapt our models to their robots and applications, from harvesting strawberries to assembling servers. Now we’re opening access to more teams.
Shipping code continues to get faster, but production debugging often takes hours of digging through logs, traces, and replays. @interfere_ helps teams understand what’s going wrong in their software, who it affects, and how to fix it.
We’re excited to back @lukeshiels and the Interfere team in their seed round, led by @HummingbirdVC.
Luke built Interfere because he wanted to spend more time building products and less time keeping them running. He took time on the product’s foundations despite advice to launch quickly. His approach to engineering: “Remove, simplify, improve, in that order.”
In our latest Designer Founders conversation, Luke shares the decisions behind Interfere, why he hires people who care about what they put their name to, and why every new hire gets a physical letter from him: designerfounders.substack.co…
Excited to announce we've raised a $5.1M seed round at @interfere_ led by Hummingbird, with Worldbuild, Designer Fund, YC, Vercel, and others.
In an age where execution is abundant, we’re building Interfere to enable the next generation of software to be exceptional from day one.

Some argue about whether you should email monthly updates or not as a founder.
@ambrook says: how about instead we mail them in a personal letter alongside a book we created?
This company is different…

one thing i learned during my time @AnthropicAI was to always question and reinvent the way you work. and when your tools don’t fit anymore, build your own tools.
a lotta wisdom from a lotta good folks here ☁️
“Is this worth my time? Does this bring me productivity, joy, or calm? I think these are the questions design has always helped answer.”
Thank you to @joellewenstein and the @AnthropicAI design team for opening up about how you work, the challenges you face, and how you see the role of design evolving on product teams.

Today @airHQ becomes an agent that can run all your creative tasks for you.
You make the work. Air handles the rest.
At @AnthropicAI, designers aren’t just adapting to faster software development. They’re building the tools that shape it.
Every designer ships code in their first week. @nateparrott's prototyping tool became the precursor to Claude Design. And the team has reshaped critiques around live demos to keep pace with faster cycles.
But faster execution makes the question @joellewenstein asks even more important: “The question isn’t just, can we make it? It’s is this worth making at all?”
