For founders, raising

Raise smarter.
Run tighter.

Arx is one quiet workspace for the early years — cap table, data room, deck analytics, investor updates, and a financial model that thinks. So you can move with precision and close with confidence.

Six dimensions, one workspace
01

Cap Table

Founders, employees, options pool, and SAFEs in one ledger. Model a priced round in seconds — pro-forma dilution, founder positions, post-money math, all live.

02

Data Room

Curate a different view per investor. Folder structure, fine-grained access, expirations, and view-only watermarks. Know who is actually reading the model.

03

Pitch Deck

One shareable link. See who viewed, for how long, and which slide they lingered on. Page-by-page heatmap turns interest into intelligence.

04

Investor Updates

Monthly cadence of clarity. Write text or embed a Loom; send from your Gmail; replies thread back to your inbox. Open rates and replies tracked per investor.

05

Financial Forecast

A five-year model you do not touch — you talk to it. "Increase S&M by 20%." "When do we break even?" Benchmarks score you against seed-stage SaaS norms.

06

Ask Arx

An AI that reads your private data — round status, deck views, model assumptions, competitor news — and answers questions a chief of staff would. Calmly.

Why Arx

You are not running a holding company.
You are running a startup.

Carta is for ten-year-old companies with general counsel. DocSend lives in a different tab from your model. Your model lives in a different tab from your update. We unified the patchwork. One workspace, one intelligence, one place to look when an investor asks for "the latest." Built for the years before bigness.

The Cadence

A quieter way to operate.

Arx is built around three weekly rhythms — and Mondays do most of the work.

01

Set the brief

Add your founders, your SAFEs, your investors, and a one-line company description. Arx now knows what to watch.

02

Monday morning

You arrive to a round-progress digest, deck-view notifications, and a short brief on industry & competitor news. The week starts pre-read.

03

Share & close

Compose the update with Arx. Tag the right investors. Ship it from your Gmail. Sign the SAFE. Move the round.

My fundraising used to live in six tabs and a notebook. With Arx, my round, my data room, and my model all answer to the same question.
