Web agency · CRM, automations and publishing

Our own agency, equipped like a client’s: a small team that works like a large one

Brain Plus AI was founded in 2026 with very few resources. Instead of hiring for data entry, follow-up and publishing, we set up the tools we install for our clients, and we use them every day.

The starting point

A young agency has the same needs as an established one: answer an enquiry quickly, follow up on prospects, publish regularly, keep its access secure. It simply has nobody to do it by hand.

We also wanted to show our clients tools we really use, not mock-ups.

What we did

1. A CRM that fills itself

Every enquiry from the site lands in Twenty, sorted, scored and given a dated task, by the CRM’s native workflows. Claude reads and updates the records through its MCP server.

2. Booking without email ping-pong

A Cal.com calendar hosted on our server: the prospect picks a slot, the meeting joins the CRM.

3. A fast site that costs almost nothing

The site moved to Cloudflare: static pages, form saved in Europe before any email is sent, a preview of every change before it goes live.

4. Regular publishing without spending days on it

Blog articles start as drafts and go live after review. LinkedIn posts are prepared, approved in one word, then published through the API at set times.

5. Automations where they help

n8n links the tools that have no direct connection: enriching a record, follow-ups, reports.

6. Access kept in a vault

Keys and passwords live in a Phase vault we host ourselves, and each tool only gets what it needs.

What it changes

No lost enquiry: every contact has its record, its score and its next action, with no data entry.
The founder spends time on clients and strategy, not on copying information from one screen to another.
A regular presence on the blog and LinkedIn, with a human review before each publication.
Tooling costs kept to a minimum, with most services running on their free plans.
A living showcase: what we offer clients, we use first.
