Ask anything about your business…
Your AI, your assistant

Not a chatbot bolted on. Your own AI, doing the actual work.

Connect the AI you already pay for. It books, invoices, texts and chases payments in your Groundbase, and every change shows up in the app as if you did it.

What you stop paying for

Two-way texting from your own number

Real threads, shared across web, desktop and Android. Bulk sends with opt-out handled.

Why it can be $19

You bring Twilio, Resend and your AI. We stay out of the way.

You connect your own accounts and pay them direct at their published rates, so we never mark you up. Everything else works on day one with nothing connected.

Twilio, for texts and calls

About $1.15 a month for a number, plus Twilio's per-message rate.

Resend, for campaigns

Free to 3,000 emails a month. One-to-one email uses your own mailbox.

Your AI, optional

Claude, ChatGPT or Cursor on the subscription you already have.

Built by one person

One developer, no investors, one price.

Every other CRM charged twice: once for the seat, again for messages you were already paying Twilio for. Groundbase is a flat $19 and your own stack: your numbers, your domain, your data. If you ever leave, you take all of it. Who it is and isn't for →

Common questions

The honest FAQ

What does $19 a month actually get me?+
Every feature, with no tiers and no caps on contacts, deals, tasks or notes. Texts and calls are billed by Twilio and email campaigns by Resend, to your own accounts at their rates. Resend's free tier covers 3,000 emails a month.
Do I have to set up Twilio to use it?+
No. The CRM, invoicing, quotes, bookings, forms, e-signatures and one-to-one email work with nothing connected. Twilio is for texting and calling, Resend for campaigns, and each takes about ten minutes with the guide when you want them.
Who is this not for?+
Teams: Groundbase is one user per account by design. And anyone who wants comms fully managed for them. If you would rather pay $80 to $200 a month than paste an API key once, an all-in-one CRM is the better fit.
How does the AI part work?+
Groundbase has a built-in MCP server. In Claude, ChatGPT or Cursor you add it as a connector, sign in once with your Groundbase email and password on our page, and from then on you ask in plain English. It uses your own AI subscription; we charge nothing for it. Most everyday work is covered; connecting Twilio, your subscription and refunds stay in the app.
Is there a sales call?+
No. There is no sales team, no demo to book and no onboarding fee. Start the trial, use it for fourteen days, decide. Questions go to support@groundbasecrm.com and are answered by the person who built it.
Mac? iPhone?+
The web app works in Safari on both, and on iPhone you can add it to the home screen. There is a native Windows app and a native Android app. No native Mac or iOS app, and none is scheduled.
What happens if my payment fails?+
We email you, and the app keeps working while Stripe retries the charge. Update your card from Settings → Account & billing any time. If every retry fails the subscription cancels and the app shows only a billing screen until you subscribe again. Nothing is deleted, and export stays available throughout.
Can I export my data, and can I cancel?+
Yes to both. Settings → Backup & export gives you every record as JSON any time, and daily backups run on our side. Cancel from Settings → Account & billing, which opens Stripe's billing page; you keep access to the end of the period you paid for, and nothing is deleted. Your Twilio and Resend accounts are yours and stay with you.
