For creators
A home for investing and business writers
Finance writers come to Castro to publish research, commentary, and shows — and to build a practice that is not dependent on a newsroom budget or an ad network.
Why Castro
Direct access, serious work
Your readers want depth. Castro lets you deliver it on your cadence, with paid tiers when the work warrants it.
Editorial freedom
Cover the names, tickers, and arguments you believe in without a homepage committee.
A model that matches the work
Research and commentary are easier to fund with memberships than with display ads.
Own the list
The subscriber file is yours. If you ever leave, you take the relationship with you.
Built in
Built for market voices
Free samples, paid depth
Use public posts to show your process. Put models, memos, or member threads behind the plan that funds them.
Audio and video extras
Add a markets show or weekend briefing without standing up a separate media stack.
Community that is on-topic
Rooms and comments let serious readers talk to you — and each other — without the noise of a public feed.
Creator tools
Monetization, higher limits, and Castro marketing sit behind creator plans when you are ready to scale.
“I can still remember the first payment from a reader who wanted the memo, not the headline.”
Publish the work the tape does not have time for
Start a Castro for markets, business, or investing and invite the readers who already trust your judgment.
