Stack

The tools we build with.

We build in the software you already pay for. These are the twelve we use most, and what we usually do with each. Logos belong to their owners; listing them doesn’t imply a partnership.

→

Zapier

Automation platform

The quickest way to connect two apps. We use it for simple, well-trodden routes where speed to launch matters more than cost per run.

→

n8n

Automation platform

Open, self-hostable and cheap to run at volume. Our default for workflows with lots of steps, branches or data you want to keep in-house.

→

HubSpot

CRM

Where most of our clients keep their leads and deals. We build intake, scoring and follow-up around it rather than replacing it.

→

Slack

Messaging

Where people already are. Most of our automations report back here, so nobody has to open another dashboard.

→

Google Sheets

Spreadsheets

Still the most useful database in small business. We treat it as a real data store with checks, not a dumping ground.

→

Microsoft 365

Workspace

Outlook, Teams, SharePoint and Excel. For firms on Microsoft, we build with Power Automate and the Graph API instead of forcing a switch.

→

OpenAI

AI models

GPT models for reading, sorting and drafting. Used inside workflows with clear limits, logging and a person in the loop where it matters.

→

Anthropic

AI models

Claude models for long documents and careful writing. Our usual pick for assistants that answer from handbooks and contracts.

→

Airtable

Database

A friendly database for operations teams. Good when a spreadsheet has outgrown itself but a custom app would be overkill.

→

Notion

Docs and wiki

Where many teams keep their handbook and projects. We connect it so pages are created and updated by the work itself.

→

Salesforce

CRM

For larger sales teams. We build intake, enrichment and reporting around your existing objects and rules.

→

Stripe

Payments

Online payments and subscriptions. We connect it to your accounts and your customer comms so money and messages line up.

Using something else?

If it has an API, we can almost certainly connect it. Tell us what you run on.
