Introducing Hemrock hosted models

The spreadsheet Fund Economics Tool now runs in your browser.

For 25 years I've shipped financial models as spreadsheets. Every cell open, every formula and assumption open for inspection and customization. Built to edit.

Today I'm introducing a model that lives in your browser: the Fund Economics Tool is now a hosted web model alongside the downloadable spreadsheet. See the demo.

The web surface gives you the same fund-economics math as the spreadsheet: set fund size, average investment size, follow-on allocation, expected return multiples, gross and net multiple and IRR, TVPI, and more. What it adds are things a hosted model can do easier than a spreadsheet.

  • Faster iteration. Auto-save, multiple saved funds and scenarios, and a dropdown to switch between strategies.
  • Easier sharing. Public read-only share links for LPs, or private links with an access code. Send a link by email straight from the tool.
  • Live scenarios. A Scenarios tab with named cases (Conservative, Base, High) and a Monte Carlo simulation, all reconciling back to your live inputs.
  • Concentration analysis. A return-the-fund view that shows the exit multiple and exit valuation each company would need, so you can sanity-check whether one win could plausibly return the fund.
  • A second opinion from AI. The Ask AI feature reviews your inputs, benchmarks them, and suggests changes to your assumptions.
  • Optional multi-user editing. A separate add-on lets a co-GP, fractional CFO, or LP advisor edit alongside you. One purchase, invitees edit for free, up to five collaborators per model.

The base purchase covers the spreadsheet, the hosted version, and read-only sharing. The collaboration license is the only feature sold separately, and only the model owner needs it.

Why now

AI is getting better at financial modeling, and the way you collaborate with AI on a model matters. A spreadsheet on your laptop is a fine place to do that, and the skill files and MCP server keep working there. A hosted model is a better place to do it when you also want to share with an LP, fork from a public sample, or have a fractional CFO edit alongside you without sending versioned files around.

Proven model structures, every cell open, every assumption editable, with whatever surface is right for the work you're doing. See the demo, get the Fund Economics Tool, or contact me if you want help using it with your fund.
