Every entity. Every flow. One canvas.

Three primitives, working together: model the structure, run scenarios against it, present the result to the client.

Op Co. Holdco Trust

Model entities.

Eleven entity types — individuals, corporations, partnerships, trusts, real estate, and more. Drop them on the canvas. Connect what owns what, what flows where.

SCENARIO A · CURRENT Tax $342,000 SCENARIO B · S-CORP RESTRUCTURE Tax $268,400 −$73,600

Run scenarios.

Change an entity type, move ownership, add a new flow. Every downstream number recomputes. Compare scenarios side-by-side — not in two browser tabs.

HARTWELL FAMILY · 2026 Page 1 of 4 EntityMaps

Present to clients.

Export a clean, branded PDF — or share a read-only link. The diagram clients see is the same diagram you reasoned with. Nothing translated, nothing lost.

I've been hand-drawing entity structures on whiteboards for fifteen years. EntityMaps is the first thing that captures how I actually think about a client's situation — and the first thing I can hand the client at the end of a meeting that still makes sense the next morning.

Why we built this

A spreadsheet doesn't model a family.

When a CPA sits down with a client who owns three operating companies, two real-estate LLCs held by a holding entity, and a generation-skipping trust drafted in 2014, they don't reach for Excel. They reach for a whiteboard.

The whiteboard wins because a structure isn't a list — it's a graph. Ownership runs in both directions. Income flows through layers. Tax events fire at boundaries you have to see to reason about. A row-and-column spreadsheet can hold the numbers, but it can't hold the shape.

A structure isn't a list — it's a graph.

Existing diagramming tools — Lucidchart, Miro, Visio — get the shape but lose the math. You can draw a beautiful entity diagram in Lucid, but the moment a client asks "what if we form an S-corp here instead of an LLC," you're back to the whiteboard, recalculating by hand.

EntityMaps unifies both. Nodes carry real tax attributes. Edges carry real flow amounts. Run a scenario and every dollar moves; the diagram remains legible because legibility was the point all along. Present it to the client and watch them understand their own structure — many of them for the first time.

This is the tool we wished we had when we were practicing. We're building it for the professionals who do the actual work, on the actual file, on the actual deadline.

Sample model

The Hartwell family, 2026.

A single-owner operating company, a holding entity, a rental LLC, and an irrevocable trust — the kind of structure that lives on a whiteboard. Here it is on one canvas, with every flow carrying a real number.

Reading the model

Nodes are entities.
Each box is a person or legal entity, carrying its own type and tax attributes — an S-corp computes differently than the trust below it.
Edges are flows.
Every arrow carries a real dollar amount — payroll, distributions, rents. Change one and every downstream number recomputes.
The highlighted path is the selection.
Select any node and EntityMaps lights up everything that touches it — here, the owner's W-2 income and the payroll flow that feeds it.
