Today, we're promoting Ashraf Alkarmi to co-CEO of @Dropbox. Ashraf and I will jointly lead the company, and after a transition period, I'll move into the role of executive chairman and Ashraf will be sole CEO. Ashraf has transformed our core business since joining — the business has gotten stronger every quarter under his leadership, and he's the leader I trust to run this company. What’s next for me: my focus right now is making sure Dropbox is in the strongest possible shape. But knowing myself, it won't be long before I'm getting credit card alerts for my Cursor token spend.

Wow! Quite a detailed blog from @Dropbox on how they optimize Dropbox Dash relevance judge with @DSPyOSS. Shout out to the Dropbox Dash team Eric Wang, Dmitriy Meyerzon, and @joshclemm !
How we used DSPy to turn our relevance judge into a measurable optimization loop, making it more reliable and scalable in Dropbox Dash.

Incredible case study that's readable yet filled with practical approaches and tactics: ✔ Use GEPA to get near-frontier performance at 1/100th the cost. ✔ Quickly evaluate new models, without having to rewrite prompts. ✔ Evolve & maintain your programs w/o full rewrites

Today, we're launching Dropbox Dash! “Where’s that file?” Four words that might be the most expensive sentence in a business. Millions wasted rewriting and rebuilding what we already know-just because context is lost. The cost isn’t just money. It’s momentum. Dropbox Dash fixes this - Dash is your AI teammate that surfaces the content and context you need to stay focused and on track.

The best AI apps need the right context and @Dropbox Dash is built to provide it. Thrilled to welcome the incredible tech and talent from @Mobius_Labs to the team. Multimodal AI will make the Dash context platform even stronger 💪

And for my fellow nerds: with Dash, we're obsessed with depth of context, not just breadth. Dash isn't just calling APIs and doing naive keyword search. We build a full semantic index of all your content that is natively multimodal: not just documents but images, videos, everything. This is the only way to build true understanding and close the context gap to make AI actually useful at work.
Our industry is spending trillions on AI models that can explain quantum physics but can't find your Q2 board deck. We're fixing this with Dropbox Dash, an AI assistant and search engine that knows about you, your work, and your company, and is deeply connected to all of your work apps.

Starting today (in the US), you can download Dash at dropbox.com/dash and get your team up and running - no six-month deployments or $50k setup fees, just sign in with your work email, connect your apps, and go. And for Dropbox business customers, Dash is now natively integrated so you can ask questions of your files in natural language.

Dropbox has always been about connecting you to your most important information. Back in 2007, we took the cloud the last mile by giving you a folder that kept everything in sync. With Dash, we're taking AI the last mile by connecting it to your actual work. This is just the beginning and there will be some rough edges, but I'm very proud of what we're launching and excited to hear what you think!

Congrats @kanjun @joshalbrecht @imbue_ai on the launch -- really great to see more innovation at the UI & systems layer for agentic coding!
Sculptor: the missing UI for Claude Code 🎨 Imagine running 5 Claudes in parallel, safely in containers, while you stay in flow. Then bring their work straight into your IDE to test/edit together. This is how one developer ships like a team. Try it with Sonnet 4.5!

Just wrapped our first @Dropbox Presents in LA with (longtime customer!) @ToroyMoi closing it out perfectly. So inspiring to celebrate the incredible artists and creators who use our platform every day. Thank you @PaulaTape @sho_shigematsu @AlexPrager @JennetLiaw and everyone who joined us - what a night!

Using Cursor + Sonnet 4 really feels like the flip in Factorio from no bots to bots. Last abstraction leap that felt like this was going from C/C++ to Python/Lisp

Had a great time with @Jasonlk at @Saastr 2025 discussing our product evolution and why I’m excited about @Dropbox's next act with Dash!
