[Contrary @contrary]

From Day 1, Contrary's mission has been to identify and invest in the world's most exceptional people. It’s enabled us to be early backers of companies like Zepto, Ramp, Hallow, Anduril, and many others.

Our student Venture Partners are a key part of this process. They’re an exceptional team of builders who work closely with us to discover the next generation of founders at universities across the US and Canada.

Each year, we run a rigorous recruitment and selection process to identify a small number of VPs to join our community. This year was one of our most selective and competitive years yet: we received nearly 1500 applications, of which we ultimately accepted 20.

They are a diverse group of exceptional builders, founders, researchers, investors, writers, engineers, and everything in between, and we are thrilled today to welcome them to the Contrary family.

This year’s class includes:
• Current and former founders who have raised over $15M+ in venture capital
• Thiel fellows, competitive programmers, Wimbledon players, published researchers, and former investors
• Product builders with apps that have served 1M+ users
• Musicians (tabla and jori players, jazz singers, and violinists) who have performed at venues around the world
• Builders of spectrofluorometers, mushroom-picking robots, solar plants, and photonic chips

As we’ve gotten to know them over the past few weeks, we couldn’t be more excited to start working together. We’re thrilled to welcome the following new Venture Partners to the Contrary family!

Over the past few months at @dedaluslabs, we’ve noticed how many talented founders from around the world are being held back by one thing: location.

There is no better place in the world to build an AI startup than San Francisco. SF is home to all the major AI labs, top talent, world-class investors, and it is where the future is being built every day. That’s why, this December, we’re giving builders everywhere a chance to break in.

We are taking over @theresidency and launching Break In—a month-long hacker house program in the heart of San Francisco.

If you’re not from SF, and you’re building an AI startup, this is your chance to join us. Build your startup on top of Dedalus’ Agents SDK or MCP deployment infrastructure and we’ll cover your stay (housing, lunch, and co-working space).

As a member of Break In, you’ll get access to all the best parts of SF. You’ll be introduced to top founders, mentors, and investors. You’ll get to skip the line at the biggest tech events. Plus, you’ll receive free API credits and expanded access to the best-in-class AI stack through our partner network of top AI infrastructure companies.

Applications open October 27th and close November 10th. We will be accepting applications on a rolling basis. Final acceptances will go out November 14th to ensure international founders have enough time to secure visas.

Ready to break in? Follow us on Twitter/X for more updates and visit the link in the comments to apply on October 27th!

We just raised an $11M seed to help developers build complex agents across any model and any tool in 5 lines of code. Our round was led by @KindredVentures (@stevejang) and @saga_ventures (@maxaltman, @braveben, @itsthomson).

At @DedalusLabs, we believe the future of AI agents isn’t linear or deterministic. Agents should know when to stop, when to branch, when to reattempt a task, and when to pause and ask for context.

As a developer, we make your job simple: define the prompt, select the right tools and guardrails, and let your agent run.
We were tired of writing hundreds of lines of code and battling Dockerfiles and infra—all for a spaghetti agent that breaks under stress.

With Dedalus, you don’t have to do things the hard way.

Our open-source SDK supports vendor-agnostic model handoffs, chaining both local and hosted (MCP) tools, and streaming across any provider—all in 5 lines of code.

Plus, our cloud infra lets you deploy an MCP server in 3 clicks so anyone can equip their agent with your tools.

Let us do the heavy lifting so your agents can fly 🪽

Thank you to our incredible team and our early supporters: @c10n, @habibh from @e14fund, @YazanElBaba from @emergencecap, @donnystalter from @SunshineLakeVC, @karrwinn from @transposevc, @liquid2V, @fpvventures, @forwarddeploy, @AntWilson, @iamcal, @Thom_Wolf, @ashtom, @HazanPrinceton, @tri_dao

[Dedalus Labs @dedaluslabs]

On Tuesday, we brought together leading researchers from @OpenAI, Princeton, and Stanford to discuss the future of LLM post-training.

With over 750 sign-ups, the conversation spanned reinforcement learning, synthetic data generation, model alignment, and real-world deployment.

Join us this Friday at our hackathon to build what’s next and see how research becomes reality.

[Dedalus Labs @dedaluslabs]

We hosted a 150-person workshop during #SFTechWeek, showing how anyone can build an AI agent with the Dedalus SDK. No experience needed.

Thanks to @EragonAI for joining and sharing how they use Dedalus in production.

it’s been just one month since @dedaluslabs hosted @ycombinator’s first-ever overnight hackathon… here’s the recap 🪽

take a look to see what all the teams built!
