For SMBs:

Lusha
Stackfix Rating:
6.4 / 10
Lusha is a solid pick for small to mid-sized businesses that want a simple, effective way to find leads. It’s easy to use, quick to onboard, and focuses on core prospecting features that help teams connect with potential customers fast. Most users can get the hang of it in under 30 minutes – ideal for lean teams that need results without a steep learning curve.
While its database isn’t as deep as some enterprise tools, Lusha holds its own – especially if you’re targeting the European market. It covers the essentials well, including bulk-saving contacts and managing exclusion lists. Its ‘Intent’ scoring helps prioritise leads that are more likely to convert, so sales teams can focus where it counts.
Lusha’s AI-powered lead recommendations are another plus. Based on past activity, the platform suggests new prospects and continues refining suggestions over time – helping teams build better lists with less effort. In our testing, it scored 6/10 for list targeting – a good fit for SMBs working at moderate volume.
There are trade-offs. It lacks some advanced features like saved searches, territory management, or robust email sequencing. But for SMBs looking for a lightweight, efficient tool with smart lead suggestions and strong European coverage, Lusha is a very good option for 2025.

For Prospecting on LinkedIn:

LinkedIn Sales Navigator
Stackfix Rating:
6.0 / 10
For sales teams that rely on LinkedIn to drive pipeline, Sales Navigator is hard to beat. Built on top of the world’s largest professional network, it gives direct access to up-to-date contact and company data – making it a powerful tool for finding, tracking, and connecting with the right prospects.
The standout feature is its advanced search. You can filter by job title, seniority, company size, geography, and more – giving your team laser-focused targeting. It also helps map relationships, showing shared connections and warm intro paths that make outreach feel more personal and effective.
Sales Navigator’s AI features add even more value. It recommends leads based on your activity, flags job changes and company updates, and surfaces timely insights that help you reach out with relevance. In our testing, it scored a 10/10 for LinkedIn contact discovery – no surprise given how tightly integrated it is with the platform.
There are some drawbacks. It doesn’t surface emails or phone numbers, so outreach is limited to LinkedIn unless paired with a separate data tool. And InMail credits are capped, which limits high-volume outbound. But for teams focused on LinkedIn as a primary channel, Sales Navigator is the best tool available for prospecting at scale.

For Data Enrichment:

Clay
Stackfix Rating:
7.7 / 10
Clay is one of the most powerful tools out there for teams that need highly enriched, customised lead data. Instead of relying on a single database, Clay connects to dozens of sources – letting you combine and filter data across providers to build exactly the lists you need. This flexibility makes it a standout for teams with specific or niche targeting requirements.
The spreadsheet-style interface feels familiar and is easy to use. You can add custom columns, enrich records using integrations, and use AI agents to pull in additional details – including scraping data from websites and platforms that aren’t typically included in lead tools. It’s perfect for teams that want full control over how they build and qualify leads.
In our testing, Clay scored 10/10 for data enrichment and research – one of the best tools we’ve seen for digging deep and surfacing hard-to-find data points.
There are trade-offs. Clay doesn’t have native outreach or CRM functionality, so you’ll need to integrate with other tools to run sequences or manage pipelines. And it’s more technical than most lead gen platforms, with a steeper setup curve.
But for teams that care most about data quality and customisation – especially for complex or specialised prospecting – Clay is one of the best lead generation tools on the market.

For Best All-in-One Lead Generation:

Apollo
Stackfix Rating:
7.4 / 10
Apollo is a top pick for teams looking for an all-in-one lead generation and engagement platform. It combines a robust prospecting engine with well-executed outreach tools, making it a strong choice for sales teams that want everything in one place.
Its prospecting features are solid across the board: a large contact database, reliable email verification, and granular filters to help teams qualify and prioritise leads. Outreach tools like email sequencing are tightly integrated, allowing you to automate personalised campaigns without switching tools.
Apollo also brings AI into the mix in a useful way. It offers AI-driven data enrichment, message suggestions, and personalisation tools that help reps craft better outreach faster. Native call transcription and summary features make post-meeting follow-up easier and more efficient.
In our testing, Apollo scored 9/10 for overall functionality – a reflection of how well its features work together as a unified platform.
There are a few limitations. The database is largely US-focused, so teams targeting international markets may find coverage lacking. And the interface can feel cluttered due to the sheer number of features.
But for sales teams that want a powerful, all-in-one platform to drive both lead generation and engagement, Apollo is one of the best options available in 2025.

How we test products
With so many Lead Generation platforms on the market, we focus on identifying the best options for small and midsize businesses. Our evaluation process reflects real-world usage, prioritizing functionality, ease of use, and overall value. Here’s how we do it:
Functionality
Lead Generation software should help sales teams find, analyze, and act on high-quality data. We start by identifying key use cases—lead enrichment, intent data, contact discovery, and predictive insights—then test how well each platform supports these needs. Tools that provide valuable insights without unnecessary complexity score highest.
User Experience & Onboarding
Sales teams need fast, intuitive tools. We test each platform’s interface by navigating core features without prior training and track onboarding time—from account setup to first data pull. Platforms that require complex setup or manual data wrangling lose points.
Data Accuracy & Coverage
The value of Lead Generation software depends on the quality of its data. We assess the accuracy, freshness, and depth of company and contact information, looking at factors like data sources, verification methods, and global coverage. Platforms with outdated or incomplete data lose points.
Integrations & Compatibility
Lead Generation software must integrate seamlessly with CRMs, Sales Engagement tools, and marketing platforms. We test how well each product syncs with key business systems, prioritizing native integrations over third-party connectors.
Pricing & Value
We compare pricing across competitors, analyzing what each plan includes and whether critical features are locked behind paywalls. Hidden costs—such as per-credit fees, add-ons for premium data access, or required implementation services—are factored into our assessment. Platforms that offer strong core functionality at a fair price score highest.
Stackfix’s Fit Score
All of these factors contribute to Stackfix’s Fit Score, a proprietary ranking system that measures how well each Lead Generation tool aligns with a buyer’s needs. It combines two key elements:
- Requirements Met – How many buyer requirements the software fulfills
- Stackfix Rating – Our expert assessment of the software’s overall quality, usability, and value
The result? A clear, data-driven recommendation that helps businesses choose the right Lead Generation software—without hours of trial and error.

But with so many options available, it’s crucial to find one that aligns with your sales process, integrates with your tech stack, and delivers real value. Here are the key factors to consider before making your decision.
- Your sales needs. Are you focused on cold outreach, account-based selling, or high-volume prospecting? Do you need verified mobile numbers for phone outreach, or is email accuracy your priority? Choosing a platform that aligns with your strategy will maximize ROI.
- Data quality & coverage. A database is only valuable if the information is accurate. Look at email deliverability rates, phone number verification methods, and geographic coverage to ensure the platform meets your needs. If your sales efforts are US-focused, some platforms may offer better regional coverage than others.
- Ease of use. A lead generation tool should make prospecting faster, not more complicated. Look for a clean, intuitive interface that enables quick lead discovery, list building, and outreach automation. That’s why Stackfix gives every platform an ‘Ease of Use’ rating—click into each product above to see how they compare.
- Integration with your tech stack. Does the platform sync smoothly with your CRM, sales engagement tools (like Outreach or Salesloft), and marketing automation software? Some platforms offer native integrations, while others rely on third-party connectors—make sure you check before committing.
- Pricing & scalability. Some platforms charge per contact export, while others limit access to premium features unless you upgrade. Consider hidden costs like API access fees, seat limits, and enrichment credits—and think about whether the platform can scale as your team grows.
- Customer support. Sales intelligence is mission-critical—so what happens if data syncing fails or a key integration breaks? Check for 24/7 support availability, response times, and self-serve resources like help centers and community forums.
