Brief

ItzSuds recounts that Girish backed him in October when he couldn’t raise funds, enabling a seed investment in Castform and providing a founder reference that reopened access to a Sequoia inference company and revived SF1. On 2026-06-11 Girish launched Castform’s open preview, claiming it automates model training on proprietary data, uses open weights to cut costs, and offers an IDE to monitor and interact with models.

When I was a loser VC struggling to raise a dollar in October & had no winners in the portfolio, Girish took a bet on me and let me invest in Castform’s seed

He then gave me a founder reference to get into a “super hot” Sequoia inference co & SF1 was back on track

“don’t train your own model” is common ai advice. it's wrong. your token bill's the proof.

today, we’re excited to launch castform into open preview. castform is the easiest way for you to train your own model, on your own data.

open-weights models are performant and much cheaper. when trained on your task & proprietary data, they beat closed models. the thing standing between you and that was weeks of plumbing & years of ml expertise.

with castform, model training is as simple as prompt engineering. @castformai

bring your agent traces or raw corpora. castform turns it into training data, picks the right algorithmic recipes, manages gpus, and gives you an ide to watch and chat with your model as it learns.

see what you can build with castform👇
