What the models said for it

Verbatim evidence the judge attached to positive labels.

“Stick with well-reviewed, scalable platforms like Pulley, AngelList Equity, or Cake Equity” Mistral Small · Cap table management · negative prompt · alternative

“If you are planning to raise money soon, AngelList is the most logical choice” Qwen 3.7 Flash · Cap table management · budget prompt · alternative

“Budget-conscious: Eqvista or AngelList Equity” Kimi K2 · Cap table management · comparative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“AngelList stopped accepting new standalone cap table customers as of mid-2026, so it's generally no longer a fresh option.” DeepSeek V4 Flash · Cap table management · comparative prompt · hard negative

“stopped accepting new customers in August 2026, so avoid it” DeepSeek V4 Flash · Cap table management · budget prompt · hard negative

“AngelList Stack closed to new customers in 2026, so it would be a caution flag if you are evaluating it now” Perplexity Sonar · Cap table management · negative prompt · soft negative

“Closed standalone cap table to new customers (August 2025)... No published pricing” Qwen 3.7 Flash · Cap table management · negative prompt · soft negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when AngelList Stack's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as AngelList Stack, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at angelliststack.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
