Lumo Data

Lumo Data is a French B2B prospecting platform and business database. According to its own materials, it maintains a proprietary base of 15.0 million French companies with verified emails and direct phone numbers, and it positions itself as an all-in-one tool for finding prospects, contacting them across multiple channels, and converting them inside an integrated CRM. The company describes its offering as GDPR-compliant and markets an unlimited-access model rather than one-off data files. The platform's core asset is its company database. Lumo Data states that it tracks 15.0 million companies, including decision-maker contacts, drawing on public B2B sources and updating continuously. Users can target companies by criteria such as NAF code (the French activity classification), region, headcount and revenue, then build lists and launch campaigns. Outreach channels include email, SMS, WhatsApp, LinkedIn, postal mail and cold calling, all managed from the same interface. A built-in CRM captures replies and follow-ups, and campaigns can be sequenced across several channels. Beyond self-service software, Lumo Data offers a done-for-you teleprospecting service: because the database is its own, its telemarketers can fill a client's calendar with qualified B2B appointments. The company also exposes its data and workflows through an API and, more recently, through a Model Context Protocol (MCP) server that connects AI assistants such as Claude or ChatGPT to a user's account. The MCP server is described as covering 196 actions spanning targeting, enrichment, lists, CRM, content and campaigns, driven in French, with each call logged, a daily spend cap, and no message sent without explicit confirmation. MCP access is reserved for the top-tier "Ultime" plan at 99 € HT per month. Lumo Data presents itself as a French platform aimed at the French market. Its pricing model centers on unlimited access to the full market rather than the classic one-shot purchase of Excel files, which the company criticizes as quickly outdated, prohibitively priced and disconnected from prospecting tools. It offers a 14-day free trial with no commitment and cites a 4.5/5 rating from more than 860 users. The company's stated origin is a frustration with existing data sources: Google Maps misses businesses without a physical storefront, Yellow Pages listings are often out of date, and LinkedIn does not expose all direct contacts. Lumo Data says it built its own infrastructure to track, cross-check and verify thousands of data points in order to create what it calls the ultimate file.

Lumo Data describes its origin as a response to a simple frustration: the impossibility of reliably and exhaustively finding all companies in France with up-to-date contacts. According to the company's own account, the founding insight was that B2B data was broken. The need first arose within the founders' own structures: while looking for new clients, they hit a wall. Google Maps did not show everyone, because businesses without a physical storefront or with a "service area" model are invisible there. Yellow Pages listings were not up to date, with databases often left abandoned, making prospecting ineffective. LinkedIn was a powerful network but did not expose all direct contacts such as professional emails and phone numbers needed to act. Faced with this, the team decided to build its own system to be certain of accessing all companies in France and not missing a single prospect. They developed an infrastructure capable of tracking, cross-checking and verifying thousands of data points to create what they call the ultimate file. This resulted in a base of 15.0 million tracked companies, with decision-maker contacts in real time, data drawn from public B2B sources and updated continuously. Initially, Lumo Data sold static company files. The company says it quickly understood that the real value for its clients was not a simple spreadsheet at a given moment. The real value was continuous, unlimited access to the entire market in order to exploit it fully. This led to a shift away from the classic model of one-shot Excel file purchases, which the company characterizes as quickly obsolete, prohibitively priced and lacking synergy with prospecting tools, toward a vision of unlimited access to all of France: see everything and exploit everything through its tools. The platform evolved into an all-in-one prospecting and marketing suite. It combines a proprietary database with multi-channel campaign tools covering email, SMS, WhatsApp, LinkedIn, postal mail and cold calling, plus an integrated CRM. Because the database is its own, Lumo Data also offers a done-for-you teleprospecting service in which its telemarketers fill clients' calendars with qualified B2B appointments. More recently, Lumo Data added an API and a Model Context Protocol (MCP) server that connects AI assistants such as Claude or ChatGPT to a user's account. The MCP server is described as covering 196 actions across targeting, enrichment, lists, CRM, content and campaigns, driven in French, with each call logged, a daily spend cap and no message sent without explicit confirmation. MCP access is reserved for the top-tier "Ultime" plan at 99 € HT per month. The company offers a 14-day free trial with no commitment and cites a 4.5/5 rating from more than 860 users.
