Just tested my site on Cloudflare’s new tool: isitagentready.com
It scores websites on how “agent-ready” they are for AI crawlers and tools — checking discoverability, content formats (like Markdown negotiation), bot controls, llms.txt, MCP servers, and more.
Surprisingly low industry adoption so far, but super useful feedback with actionable fixes.
Go scan yours → isitagentready.com
What score did you get? 👀

Today, we are excited to introduce isitagentready.com — a new tool to help site owners understand how they can make their sites optimized for agents. cfl.re/4tgEUPc

If you want to know EXACTLY where CLAUDE DESIGN is incredible and where it falls short, you should probably watch this
-Wireframing = 9/10
-Mobile app design = 8.5/10
-Deck research & design = 8.7/10
-Video creation - 4.5/10
fully unscripted episode of @startupideaspod
no one is showing you the failures
they are just saying "RIP designers"
watch the real truth below

There’s $1T up for grabs for agent-first startups and this window is WIDE open. Probably 10,000+ niches.
How it plays out:
1. Every SaaS company follows salesforce and goes headless within 18 months
2. a new category of "agent-native" startups emerges that treat salesforce, HubSpot, workday etc as dumb backends. the startup IS the agent. the SaaS is just the database.
3. the entire consulting/services industry around enterprise SaaS gets compressed into software. the agent replaces the implementation team.
4. outcome-based pricing becomes default. nobody pays per seat when the "seat" is an agent making 10,000 API calls a minute. you pay when revenue hits your account.
5. the winning founders are ex-operators who understand a vertical workflow cold. the code is the easy part. knowing that a property manager spends 14 hours a week on lease renewals? that's the insight worth $100M.
6. distribution becomes the moat. when anyone can wire agents to APIs, the company with the audience and the brand wins. media + agents is the new SaaS. There’s a rush to incubate live/short form shows.
7. Silicon Valley goes all influencer. Roy lee gets this. Pat Walls gets this. Sam Parr gets this.
8. the first $1B agent-native company in each vertical will look nothing like the SaaS it replaced. smaller team, higher margins, no implementation cost, no churn from bad UX because there is no UX.
the fastest path to wealth right now: find an industry that still runs on dashboards, phone calls, and spreadsheets. build the agent-native version. charge per outcome. own the workflow end-to-end.
someone reading this right now is going to build a $100M company off this exact shift. tell me about it on the @startupideaspod when you do. Im rooting for you.
Less reading, less bookmarking, more building.
the last wave rewarded people who built pretty interfaces on top of ugly data.
I think this wave rewards people who build smart agents on top of exposed APIs.
Or who just build the APIs themselves
Here we go

Welcome Salesforce Headless 360: No Browser Required! Our API is the UI. Entire Salesforce & Agentforce & Slack platforms are now exposed as APIs, MCP, & CLI. All AI agents can access data, workflows, and tasks directly in Slack, Voice, or anywhere else with Salesforce Headless 360. Faster builds, agentic everything. 🚀 #Salesforce #Agentforce #AI venturebeat.com/ai/salesforce-…

First week of FSD in Netherlands and owners are saying it’s smoother than expected on their crazy roundabouts.
UK 🇬🇧 owners: How jealous are you right now on a scale of 1-10? 😂
English
Holy shit.
Now everyone will be able to use their @OpenClaws and all the other agentic platforms to build apps on top of X.
Here's the secret: build lists.
Lists are how you build apps.
The pattern:
Build a list of your favorite football team. Or whatever you are into.
Then ask your AI agents "build an app showing me all the important news about my favorite football team."
In minutes you'll have an app.
And that's just the beginning.
Your agent can build a script about your favorite football team that you can take to places like Google's Notebook LM.
Now you have a video, a podcast, a slide deck, a game, a mind map. All about your favorite football team based on real time news.
You can do the same with something like @HeyGen, create an avatar of your favorite football player. Now you will have your favorite football player telling you everything that's happening on the football team.
And I could go for hours about how many things you can build and not even cover a fraction of them.
This is huge.
Thank you @elonmusk for making it possible to make millions of agentic apps affordably on top of X.
Start building!

@Scobleizer what's UP!! Did you have anything to do with the change to X API cost for get calls?? I got the following email on Thursday... Hello X API developers, We’re excited to announce an update to our X API pricing that makes accessing your own data more affordable than ever. Owned Reads are requests made by your own developer app for your own posts, bookmarks, followers, likes, lists & more. Starting Monday, April 20, 2026, these endpoints will be priced at $0.001 per request (equivalently, 1,000 resources for $1): GET /2/users/{id}/bookmarks GET /2/users/{id}/blocking GET /2/users/{id}/muting GET /2/users/{id}/pinned_lists GET /2/users/{id}/tweets GET /2/users/{id}/mentions GET /2/users/{id}/liked_tweets GET /2/users/{id}/followers GET /2/users/{id}/following GET /2/users/{id}/owned_lists GET /2/users/{id}/followed_lists GET /2/users/{id}/list_memberships This change significantly lowers the cost of common operations such as fetching your own posts, followers, likes, bookmarks, lists, and more. Additional updates effective Monday, April 20, 2026: Writes via X API will increase to $0.015 per post (from $0.01). This applies to the main posting endpoint: POST /2/tweets. Posting a URL via X API will be priced at $0.20 per post, except for summoned replies (which will remain at $0.01). Following, Likes, and Quote-Posts via API Writes will be removed for all self-serve tiers. This affects the following actions:POST /2/users/{id}/following (and DELETE for unfollow) POST /2/users/{id}/likes (and DELETE for unlike) Quote-posting via POST /2/tweets (when using the quote_tweet_id parameter) These adjustments reflect our ongoing commitment to supporting the developer community while ensuring sustainable platform operations and helping you build even better experiences on X. For full pricing details, including the complete rate card and updated documentation, visit the X API Pricing page.

Something big has changed at Giga Texas with Cybercab production … ~ 14 in the outbound lot WITHOUT STEERING WHEELS! Earlier this week, the production line has begun what we are all waiting for and I would expect to see many more starting on Monday, 4/20 🤠 A big step forward!

@claudeai keep pumping out features. Hard to keep up. I’ll be jumping on now!

we just launched one of the coolest features for marketers today: Claude Design 🎨 I've posted a lot about building marketing tools without being technical, and this is the visual side of that. I described a landing page editor and Claude built me one. here's an example of my actual workflow with it 👇

Tesla is now offically in Estonia. I guess this will help sales and BEV penetration. 🇪🇪
Estonia reported 5 Tesla sales and 0.3% market share in March. BEV penetration is 6.7% and Tesla has 4.2% of this segment.
• 60% Model Y and 40% Model 3
• -29% vs. March last year and +0% compared to December the third month of the previous quarter
• Year-to-date -43% over same period last year
• Year-to-date is 21% or 2.5/12 of last year's total
