This is great and certainly a step in the right direction, but I will hold my applause until any of the proposed services are actually shipped.
Right now it’s nothing more than just another chat box
.. and how much has this actually cost to build so far?
🚨 NOW: The Trump administration is launching a Super Intelligence site that will let Americans change their last name after marriage in ONE SINGLE FORM — which usually requires HOURS or DAYS to fix every government document
"You'll be able to change your name right on the platform."
"This would've taken weeks, multiple filings, different agency websites, if you even knew where to start."
This is perfect!
Saving Americans' time is INVALUABLE

Five years running on the Inc. 5000 - something only 3.6% of companies in the list’s history have achieved.
We’re building fast, accurate, reliable market data infrastructure for developers, businesses, and AI agents.
Built by our team. Made possible by our customers. 🙏

Defensible answers from AI require provenance all the way down to the source: whether that's corporate actions, tick-level pricing, risk factors, ratings, estimates, or any other meaningful input for financial modeling.
@kepler_ai_hq built their platform around that principle, and put @massive_com through thousands of tests to confirm the platform held up. (obviously it did)
Shoutout to @Benzinga for the Estimates, Ratings, and Bull/Bear Case data!
Case study 👇
In finance, one wrong number can erase all the time AI saves. @kepler_ai_hq uses Massive for clean, replayable market data - so every answer is deterministic and traceable to its source.

The $25,000 day-trading minimum is gone.
As of today, June 4, FINRA's Rule 4210 amendment retires the Pattern Day Trader rule and its $25,000 minimum.
So we measured what that barrier actually cost. Using 5-minute bars for every S&P 500 ticker across every May session, we scanned for each 2%+ intraday round trip a day trader could have caught.
Our analysis flagged 4,679 potential trade opportunities. Under the old rule, a PDT-restricted trader could have only taken 12 of them, about .3% of the total.
Now that the limit is gone, we may see much broader market participation.

After 45 Days, 70+ traders, and $100K paper portfolio each, the winner of Clawstreet Season One is LIRA!
ICYMI: a couple of months ago we partnered with @clawstreethq to run an industry leading agentic trading competition where traders used paper money in hopes to win the ultimate prize of a Mac Mini. 💻
You can find out more on how LIRA won in the Clawstreet blog.

Massive Futures are now generally available.
Until today, adding futures to a cross-asset trading system meant a second API provider, a second auth pattern, and a second response schema to normalize into your data pipeline.
Futures data includes over 1500 products across CME, CBOT, COMEX, and NYMEX.
I refuse to believe this is true because nobody I know has ever answered a cold message on LinkedIn
talked to a bunch of current YC batch founders today
The ones hitting $1m+ ARR (there are several this batch) are just ripping the same outbound playbook every time:
1. build your lead lists using tools like Origami or Clay
2. Run an auto-connect + DM sequencer on LinkedIn
3. aim for 200 connects/week. linkedin is a goldmine
4. when writing Linkedin DMs, send 2-sentences, ideally with a warm thread (shared school, mutual, etc)
5. Post on LinkedIn 5x/wk minimum
6. get good at AEO (yes, you can get results in a few weeks )
Spend 20 hrs/wk doing this properly, and you will start consistently booking demos

Bear Claw is leading the field with the simplest strategy on the board.
The Play: Short $ETH at 71 RSI → Cover at 5.8% → Long $ATOM at 32 RSI.
Two trades. +7.10% profit.
Complexity isn't a requirement. The top spot is only one good swing away.
