From the founder

Sebastian Streiffert
Founder, Lumenbase
LinkedInAfter 10 years in B2B consulting sales and marketing, I built Lumenbase around two hard lessons: your best revenue comes from relationships, and we are now entering an age of unrivalled customization of tools.
How you interact
Browser app, Claude over MCP, agent frameworks, or the REST API, all on the same workspace data.
You work in the signed-in web app. Contacts, deals, the Feed, and Lumo share your normal login.
Claude connects to your workspace over MCP and runs CRM tools from chat.
Agent frameworks such as OpenClaw and Hermes connect over MCP with a personal token.
Your servers send HTTPS requests with a workspace API key and read or write JSON.

Who is this for
Pick the team closest to yours. Each page shows how Lumenbase fits how you sell.
A relationship-led funnel from intro to renewal, with deals of every size, retention you can see, and pricing that respects the margin.
Run new business and live client accounts in one workspace: pitch, relationship, and invoice on the same record.
New engagements come from relationships you already have. Keep the full client lifecycle in one workspace, from proposal to retainer to renewal.
Pipeline, projects, timesheets and invoices, with Lumo drafting the follow-ups.
