The open-source, simple agreement that lets investors fund your startup now for shares of stock later. Created at Y Combinator by Carolynn Levy in 2013 and used to raise over $15B for YC portfolio companies.

How SAFEs work

Pick the fundraise amount. The valuation cap follows.

The biggest advantage of the post-money SAFE is that the amount of ownership sold is immediately transparent and calculable for both the founder and the investor. Start from how much you're targeting and how much ownership you're willing to sell — the valuation cap follows from the two.

Say you're targeting a $1M raise and 15% ownership sold. Your post-money valuation cap is $1M ÷ 15% = ~$6.7M, or "I'm targeting $1M at $6.7M post / $5.7M pre." Raise less on that cap and you sell less: $500k is ~7.5%, $800k is ~12%. You can also raise on more than one cap — $500k at a $5.5M cap (~9%) plus $500k at an $8.3M cap (~6%) gets you to the same ~15% sold.

Origin begins rolling out today in early beta on all paid plans. They're starting with the essentials, designed for agent scale: repos, pull requests, code browsing, and GitHub sync. Agent-native features ship soon.

Your GitHub repos can sit alongside the ones Cursor hosts. Connect GitHub to Cursor, pick your org, and you'll see the repos you can sync. Select one and Cursor pulls it in. You choose what gets synced and can disconnect a repo at any time. Anyone with read or write access to a synced repo can view it in Cursor too.

Synced repos update in real time. Browse, search, and pull from the copy in Origin. Pushes keep going to GitHub, which stays the source of truth for anything started there. Icons next to each repo name tell you which ones Cursor hosts and which came from GitHub.

Every repo has pull requests. Open one to see the timeline, commits, checks, and files changed. Review the diff, leave comments, and merge.

Pull requests on synced repos sync both ways: comment in Cursor and it posts to GitHub, react or reply on GitHub and it shows up in Cursor within seconds. Got a review assigned to you on GitHub? Review and merge it from Cursor.

Your code, PRs, and agents are now in the same place. Ask Cursor questions about code you're browsing. It can answer, make changes, update PRs, or push a branch.

OpenRouter is being acquired over five times the $1.3B valuation the AI routing startup raised at in May.

OpenRouter was found in 2023 and has around 8M users.

Future Claude models will generate text that contains a watermark. This is a way of determining the likelihood that Claude was involved in writing the text, and we, along with several other major AI providers, are implementing this change to comply with the EU AI Act.

As per Anthropic's statements:

• Claude is implementing watermarking to comply with the EU AI Act. Other major model developers have signed the same Code of Practice and will also be implementing watermarking;
• Their watermarking method doesn’t have any practical impact on the quality or content of Claude’s outputs;
• The difference between watermarked and un-watermarked text will not be distinguishable to readers;
• Nothing is added to the text and there are no hidden characters;
• Watermarking doesn’t require extra tokens, and will not be more expensive;
• Watermarks can’t be traced to a specific person, organization, or chat.

Start includes generous access to Grok 4.5 and Composer, so you can plan, build, test, and ship with agents every day.

Cursor Start includes:

• Generous access to Cursor models. Run Grok 4.5, our most powerful Cursor model, and Composer, our most price-efficient coding model.
• More agent requests than the Free plan, across desktop, web, iOS, and the CLI, so you can build every day.
• Always-on cloud agents. Kick off long-running cloud agents that build, test, and open pull requests while you keep working.
• Cursor for iOS. Launch agents or control existing ones from your phone, then pick the work back up on your desktop.
• Extend Cursor across your workflow, with plugins, MCP servers, hooks, and skills.
• Local pricing. ₹649 per month, tax inclusive, billed monthly in INR with UPI or card.

Cursor Start sits between our two other individual plans, Free and Pro.

Free gives you a way to try Cursor with no payment required. It includes access to Composer and a limited number of local agent requests each month.

Pro is for developers who want access to every major model, including the most advanced ones from other labs, along with Bugbot, Auto mode, Automations, the Cursor SDK, and on-demand usage past the included limits. Cursor Start covers everyday building. When you need more, it's easy to change your plan to Pro.
