There’s a fairly widespread belief in the sales world: to prospect effectively, you have to put in the time. A lot of time. Sending dozens of messages a day, manually updating your CRM, searching for email addresses one by one, following up at just the right moment...
It’s true, but it’s also a somewhat outdated view. In recent years, an ecosystem of discreet, often overlooked sales tools has completely transformed the landscape for freelancers, entrepreneurs, salespeople, and founders who manage their own lead generation. These tools don’t necessarily make the headlines in comparison reviews. They aren’t always sponsored by major platforms. And yet, those who use them every day couldn’t do without them.
In this article, we’ll introduce you to five seriously underrated sales tools, along with an honest breakdown of each one: what they do, who they’re best suited for, how much they cost, and—most importantly—why they deserve a permanent spot in your sales stack.

Surfe (formerly Leadjet) tackles one of the most mundane yet time-consuming challenges of B2B prospecting: manually entering data between LinkedIn and your CRM. If you’ve ever copied and pasted a name, job title, company, or email address from LinkedIn into HubSpot or Pipedrive, you know exactly what we’re talking about.
Surfe is a Chrome extension that integrates directly into the LinkedIn interface. With just a few clicks, you can add contacts to your CRM, automatically populate their profiles, find their verified work email addresses, and view CRM information associated with a profile in real time—all without leaving LinkedIn.
Some of the features that make a difference in your daily life:
The time savings are real and measurable. Some users report saving between 45 minutes and 1 hour and 30 minutes a day simply by eliminating the need to re-enter data.
Managing your prospecting on your own takes a huge amount of time. Surfe eliminates the friction between searching on LinkedIn and populating your CRM, allowing you to stay focused on what matters most: human connection.
When you're doing your own prospecting without a dedicated sales team, every minute counts. Surfe lets you prospect in a structured way without sacrificing productivity.
Those who manage multiple LinkedIn profiles stand to benefit greatly from automating the administrative tasks. The data is imported into the CRM cleanly, with no data entry errors.


Clay is probably the most underrated tool on this list—not because it’s unknown to insiders, but because its true potential still eludes many teams who look at it without really understanding it. It’s a tool that takes a little getting used to, but once mastered, it literally changes the way you manage your prospecting.
Clay is a platform for data enrichment and sales workflow automation. Specifically, you import a list of prospects (from LinkedIn, CSV, or another source), and Clay automatically enriches each record by querying over 75 data sources simultaneously: business emails, phone numbers, company news, job postings, technology used by the website, and many other signals.
All of this can then be used to generate highly personalized outreach messages directly from the platform, thanks to the integration of AI-powered copywriting.
Clay is designed for professionals who enjoy building workflows, testing hypotheses, and quickly refining their lead generation process.
If you manage lead generation campaigns for your clients, Clay allows you to deliver enriched and personalized lists at a speed that no manual process can match.
Once the target market has been clearly defined, Clay allows you to put your prospecting on autopilot without compromising on the level of personalization.


Most CRMs are built around a pipeline model: columns, stages, deals. Breakcold takes a completely different approach. Its premise: modern sales is first and foremost about relationships, not processes. And to nurture relationships, you need to engage with your prospects where they’re active—particularly on LinkedIn and Twitter/X.
Breakcold is a social selling CRM. It brings together your lead tracking, your prospects’ social media posts, and your past and future interactions into a single interface. The idea is to help you “warm up” your contacts by liking and commenting on their posts before approaching them with a sales pitch, which dramatically improves response rates.
This approach may seem counterintuitive to those accustomed to mass outreach, but the results speak for themselves for anyone targeting niche or high-value-added markets.
If you primarily acquire customers through professional networks, Breakcold is likely the best tool for your needs.
In situations where trust is a prerequisite for closing a deal, maintaining a regular and visible presence with your prospects makes all the difference.
Selling as a founder often means selling your vision, your credibility, and your personality. Breakcold helps you build these relationships in a structured way, without leaving anyone behind.


PhantomBuster has been around since 2016 and remains largely under the radar for sales teams that aren't from the growth marketing world. Yet it is one of the most versatile and powerful tools for automating time-consuming tasks related to digital prospecting—without writing a single line of code.
PhantomBuster is a no-code automation platform that offers hundreds of "Phantoms"—preconfigured scripts—that automate actions on LinkedIn, Sales Navigator, Twitter, Instagram, ProductHunt, and many other platforms. Each Phantom performs a specific task: extracting profiles, sending invitations, retrieving emails from a list, scraping comments from a post, and more.
This is not a spamming tool. It is a tool for intelligent data collection and targeted automation that can be integrated into broader workflows.
Those who build automated data mining pipelines and enjoy retrieving data wherever it may be will find PhantomBuster to be a valuable ally.
Extracting hundreds of profiles from a LinkedIn search in just a few minutes is what PhantomBuster does better than most alternatives.
When integrated into a broader automation workflow, PhantomBuster can trigger entire sequences based on simple collection signals.


DropContact may be the most low-key tool in this selection, but it addresses a very real problem faced by anyone engaged in B2B lead generation: finding their contacts’ professional email addresses in a reliable and legal way, without having to pay for access to a third-party database.
Unlike most data enrichment tools that rely on databases (often purchased, sometimes poorly maintained), DropContact works differently. The tool recalculates email addresses in real time using the first name, last name, and company domain name. It then runs the results through several verification algorithms to ensure that the email address found is valid and active.
The result: no databases sold to third parties, built-in GDPR compliance, and verified email addresses with a very high delivery rate. It’s a radically different approach that deserves to be known.
DropContact was designed for the French market, with particularly strong coverage of French companies and access to SIRET data.
For organizations operating in regulated industries or those with strict internal data compliance policies, DropContact offers true peace of mind.
The bulk deduplication and enrichment feature is invaluable for overhauling a database that has accumulated data over the years.

To help you understand how each of these tools fits into your overall strategy, here is a quick summary of their key differences.
| Tool | Primary function | Ideal Profile | Admission price | Distinctive strength | GDPR |
|---|---|---|---|---|---|
| Surf | Sync LinkedIn ↔ CRM | Any active LinkedIn profile | ~$29/month | Direct integration with LinkedIn | ✅ |
| Clay | Multi-source enrichment + AI | Growth / Sales Operations | ~$149/month | 75+ enrichment resources | ⚠️ Depends on the source |
| Breakcold | Social Selling CRM | Solo / Founder-led sales | ~$29/month | Social feed integrated into the CRM | ✅ |
| PhantomBuster | Web Automation and LinkedIn | Growth / Technical Profiles | ~$56/month | 100+ No-Code Phantoms | ⚠️ Use with caution |
| DropContact | B2B Email Enrichment | French Market / GDPR Compliance | ~$24/month | Real-time calculation, without a database | ✅ Native |
These five tools are not mutually exclusive. On the contrary, some of them work very well together: DropContact or Clay to enrich your lists, Surfe to push them into your CRM, Breakcold to nurture your relationships, and PhantomBuster to automate the initial data collection.
You can find the discount for each of these in theSales, Automated Prospecting, and Data Enrichment Categories on Freelance Stack.
Here are a few frequently asked questions to help you explore these topics further and guide your decision-making process when choosing your tech stack.
All the tools in this selection were chosen in part because they work well on their own. Surfe, Breakcold, and DropContact are particularly well-suited for users who handle their prospecting independently. Clay and PhantomBuster take a little more time to get the hang of, but are still quite accessible once you have a clear outbound strategy.
That’s a valid question. Surfe and Breakcold rely on normal use of LinkedIn and do not violate its Terms of Service. PhantomBuster requires more caution: the tool is powerful, but using it at high volume or in an aggressive manner can result in account restrictions. The golden rule remains the same: automate normal human behavior, not spam.
A data enrichment tool helps you complete and verify your contact data (email addresses, job titles, companies). A CRM like Breakcold helps you manage and track business relationships over time. The two are complementary: data enrichment feeds the CRM, and the CRM structures the relationship.
If you're just starting out and using LinkedIn for lead generation, start with Surfe: it saves you time right away and has a very flat learning curve. If your goal is to find your prospects' email addresses reliably and in compliance with GDPR, DropContact is an ideal place to start. Clay and PhantomBuster are better suited for intermediate or advanced users.
Clay, Surfe, PhantomBuster, and Breakcold provide strong coverage of international markets. DropContact, on the other hand, is particularly strong in the French and European markets. For targeted prospecting outside of France, it may be beneficial to combine DropContact with Clay to maximize coverage.
Absolutely, and it’s actually recommended. An effective workflow might look something like this: lead generation with PhantomBuster, data enrichment with Clay or DropContact, CRM synchronization with Surfe, relationship management with Breakcold, and sending sequences with Lemlist or Instantly. Each tool plays a specific role in the process without competing with the others.
Freelance Stack exclusive deals for all of these solutions. You can browse the Categories to automated lead generation anddata enrichment to find all available offers, some of which include several months free significant discounts on annual plans.
