After Arabella: Castilla Impact, and a Seat on Capital for Good

FACT / SELF

Castilla Impact’s about page presents the firm as a consultancy for “nonprofits, fiscal sponsors, philanthropic families, institutional donors, and corporate philanthropy teams,” “led by a seasoned nonprofit tax lawyer, former private foundation general counsel, and former managing director for a leading philanthropic and nonprofit consulting firm.” It dates the Arabella managing-director role “from 2020-2025” and describes the present shop in the first person plural. Capital for Good’s board-of-directors page names “Isaiah Castilla, Director” and calls him “Founder and Principal Consultant of Castilla Impact,” then repeats the Arabella and Democracy Fund résumé.

No state formation filing, IRS determination letter, or dated launch release for Castilla Impact was located this pass. The 2025 end-date for Arabella is his. This site does not invent a founding month. It does not invent clients. Capital for Good is a separate organization’s board page, used here as a primary for the director listing and for the founder title they printed.

Opinion

The following is commentary by this site. It is not a finding of fact and not a legal conclusion.

Compiler take

He left the Arabella letterhead and hung out a shingle that sells the same product: how to run the nonprofit shop. Capital for Good put him on the board. That is the after-picture. Not a tribute. Not a vanishing act.
