TL;DR
- The by far best sales prospecting tools on the market help companies not just hand over more contacts but to find the right type of contacts through intent-led data signals.
- There’s no single “best” prospecting tool; use a stack and combine tools that are good at different things. Tools with Intent data, like for example A-Leads, help you narrow down your list to the most relevant segments of the market that actually want to buy from you.
- When used correctly, these B2B sales prospecting tools quickly shift sales from volume to relevance. Which ultimately results in fewer random spammy emails to fewer, but better conversations that lead to more conversions.
1. A-Leads

A-Leads is one of the best options on the market for an all-around tool that gives you exactly what you’re looking for in data. It’s not just tailored to the companies with the deepest pockets.
With A-Leads, companies at any scale, whether you’re starting out, have an established agency, or are a big sales team as an enterprise, A-Leads will be able to provide you with the highest quality data for a fraction of what other providers charge for outdated information.

Best use case: If you want a more low-scale ‘’close relationship’’ approach to prospecting and work with more manual labor instead of automating your list building process.
