Principles is a woman-/q***r-/veteran-owned specialty coffee cafe opening soon in the Red Hook section of Brooklyn. The shop is modelled after the dissident, anti-war, pro-peace Vietnam-War-era and Iraq-War-era GI coffee houses that operated wholly as coffee shops and eateries and also provided space for activist gatherings, grassroots charity and mutual aid events, and community-building endeavours. Katie, the sole owner of Principles, is a Marine Corps veteran, active in the pro-peace movement, and the child of a bartender and waitress and thus she has a literal lifetime of experience in all things bar, restaurant, and cafe. Most recently, she has been a barista and manager at some of New York’s premiere boutique cafes and has devoted countless hours to professional development in the realm of coffee brewing and espresso. So much of the NYC coffee scene is taken up by serial entrepreneurs with no cafe or restaurant experience who come from money and thought it would be cute to own a cafe, because how hard could it be, right? Katie doesn’t come from money, but she’s scrappy and has a whole village on her side. It’s cliche to say that there’s no better time than now, but seriously there is no better time than *now* because the forest fire of 2020 has razed the landscape of stagnant growth and from it seeds of the next generation of businesses and ideas can flourish in the wake. The city is in a time of record high commercial vacancy and there is an overwhelming pent-up demand to gather and sip drinks in person and Principles is poised to thrive in that environment.

MY BRETHREN THIS IS SUCH A HUGE ACCOMPLISHMENT I HAVE OFFICIALLY PAID OFF THE LAST OF MY INSTITUTIONAL, NON-FRIEND LOANS!!!! $83,000 IN LOANS OFFICIALLY DONE!!!

fr fr fr, without Hebrew Free Loan Society of NY princi would not exist!! way back in 2022 when i was trying to make this idea a reality HFLS came across my radar. less than a month after applying for one of their small business loans i had $25,000 from them in my bank account. i had bad credit, no collateral, and only my vision to work with. they interviewed me and believed in me enough to lend to me (i needed one nyc resident with good credit as a co-signer).

then, in 2023 when i was going through my wild health odyssey i took on an additional $8,000 loan to weather the storm. i paid off those first two loans in early 2024 but realised i still needed another capital infusion to make it to a place of sustainability so i took on a third loan of $50,000. and last week i made the final payment on that loan!!

it’s an aggressive repayment schedule meant to pay back loans in two years, but it’s 0% interest. and i’m goy-af, there’s no jewish requirement for receiving a hebrew free loan society loan!

ima take a breather for a month and then hop right in to repaying all of the friends who so generously loaned me money over the years (a total of half a dozen ppl amounting to about $50,000)

in a rare case of a cold-call going well, this guy Jack Nixon cold-DMs me last month asking if he can film a commercial for princi. seems maybe not worth the trouble but i go and look at his profile and goddamn he’s got some good sh on there. i run it by a few friends who agree with the quality and then p**f we get this awesome lil thing! thank you jack!!!
