About Hemrock

Hemrock builds financial models. Founders use them to plan a business and raise a round, venture funds use them to forecast a fund and report to LPs. The models are spreadsheets, Excel and Google Sheets, with every cell open and every formula documented. The software, the workshops, and the advisory all serve that same work.

I have built financial models since 1998, and I have done it under Hemrock, formerly Foresight, for twenty years. The person on the other end of support is me, Taylor Davidson.

Built to edit

Most people point AI at a blank sheet and ask it to build a model from scratch. I think that is backwards. An AI writing the structure from nothing gets the mechanics right and the logic wrong, and you have no easy way to tell which parts are which.

So the models here start from a proven structure: the sheet layout and the formulas, plus the checks that catch an error before it moves a decision. You and your AI edit from there. That is the whole approach, which is why every model is open, documented, and licensed for you to take apart.
