In the field of B2B prospecting, databases play a central role. They allow companies to access detailed information about potential prospects, such as their contact details, professional roles, or the companies they represent. Software such as LeadFuze relies on massive databases, sometimes containing millions of contacts, to provide users with lists of prospects segmented according to specific criteria (industry, company size, location, etc.). These tools offer a practical solution for sales and marketing teams by reducing the time needed to manually search for prospects.

LeadFuze uses a static database approach, which is periodically enriched from various sources, such as professional directories, websites, or partnerships with data providers. This method allows it to cover a wide range of industries and regions, which is particularly useful for large-scale businesses.

However, the very nature of these massive databases raises a crucial question: data freshness.

Unlike tools such as Emelia.io, which relies on real-time scraping of LinkedIn Sales Navigator (LSN), LeadFuze's data can quickly become outdated, limiting its effectiveness in dynamic contexts.

Strengths

• Massive database: 500 million profiles, 10 million companies, verified by AI.

• Advanced filters: Targeting by AdWords budget, technologies, or growth.

• Robust cold emailing: Sequences, A/B testing, email validation.

• Seamless integrations: Salesforce, HubSpot, Mailshake.

• Versatility: Suitable for large teams and agencies.

Weakness

• No native LinkedIn automation.

• Limit of 1,000 emails per list, requiring the creation of multiple lists.

• Limited European coverage, currently being improved.

Waalaxy is a LinkedIn automation and multi-channel prospecting platform that simplifies B2B lead generation for over 100,000 users. It automates connection requests (up to 200 invitations/week, respecting LinkedIn limits), personalized messages, and profile visits to boost visibility, with a maximum of 800 actions per month.

A Chrome extension allows you to scrape LinkedIn Sales Navigator results (up to 2,500 profiles/day), extracting data such as names, titles, and companies. The Email Finder, through a partnership with DropContact, locates verified emails, billed only if found, ensuring a low bounce rate. Multi-channel sequences are a major asset: for example, send an email if a LinkedIn connection is ignored or schedule conditional follow-ups.

The Waalaxy Inbox centralizes LinkedIn conversation management with tags, filters, reminders, and templates, making exchanges seamless. The tool integrates with CRMs (HubSpot, Pipedrive, Zapier) and provides detailed analytics (20-30% acceptance rate, responses, conversions). Designed for salespeople, marketers, freelancers, and recruiters, Waalaxy boasts an intuitive interface and French-language support, but its dependence on Chrome poses a risk of detection by LinkedIn.

Strengths

• LinkedIn automation: Ultra-efficient connections, messages, and visits.

• Multi-channel sequences: Conditional scenarios (LinkedIn + email).

• Simplicity: Intuitive interface, built-in tutorials.

• French support: Ideal for French speakers.

• Email Finder: Reliable partnership with DropContact.

Weaknesses

• Risk of being banned via Chrome extension.

• Recurring bugs (blocked campaigns, integrations).

• Price increases since 2023.

Emelia.io is an all-in-one B2B platform that combines LinkedIn automation, cold emailing, and data scraping, with 100% cloud-based operation to minimize the risk of LinkedIn restrictions. It automates connection requests, messages, and profile visits on LinkedIn (1 to 20 accounts depending on the plan), while respecting the platform's limits (up to 300 connections/week).

Its LinkedIn Sales Navigator scraper extracts up to 30,000 results per search (names, titles, companies), although the exact method remains unclear for compliance reasons. Emelia.io takes a radically different approach by relying on real-time scraping of LinkedIn Sales Navigator (LSN). This method involves extracting data directly from LinkedIn, the most up-to-date professional platform for contact and company information. Here's why this approach outperforms static databases:

1. Always Fresh Data: By scraping LSN in real time, Emelia.io ensures that information such as job titles, email addresses, and phone numbers are as current as the LinkedIn profiles of the prospects. This significantly reduces the risk of errors or outdated data.

2. Accuracy and Relevance: As LinkedIn is a primary source for professional information, the data extracted by Emelia.io is often more accurate than that found in aggregated databases, which may include errors or duplicates.

3. Affordable: Emelia.io offers a credit-based pricing model, with a cost per email (approximately $0.019) that is significantly lower than software such as LeadFuze, where the cost per contact can reach several dollars. This accessibility is particularly advantageous for startups or small teams.

4. Flexibility and Agility: Real-time scraping allows Emelia.io to adapt to specific user needs, extracting only the data relevant to a given campaign, unlike pre-populated databases that sometimes include unnecessary information.
