Best Lead Generation Tools for Agencies in 2025

Now is an exhilarating time for agencies to discover lead generation tools. There are so many options available for agencies to capture leads and nurture them, from sophisticated CRMs to automation software powered by AI! 

In this article, we’ll outline some of the best lead generation tools for agencies and list their notable features.

HubSpot

HubSpot is simply the most well-rounded software; it brings together everything agencies need in one unified ecosystem. It’s so simple to do one thing: design and deliver the end-to-end customer experience. It even offers free tools for landing pages, advertisements, forms, and automated emails.

It also provides deep analytics and reporting dashboards. Instead of juggling disconnected tools with unclear attribution, you get full visibility into the customer journey.

Plus, it comes with contact management and CRM integration built right in. Leads are automatically tracked and organized in the free CRM, making it effortless to nurture, segment, and analyze prospects over time.

Pros of HubSpot

• All-in-one solution. It seamlessly combines a robust CRM with marketing, sales, and customer service tools. 
• Powerful AI and automation features
• Comprehensive lead generation tools.
• Ease of use
• HubSpot’s App Marketplace offers thousands of integrations with other tools.

Cons of HubSpot

• High and complex pricing
• Essential features, such as custom reports and advanced automation, are often not available on the free or Starter plans. 
• For smaller agencies or those with very specific needs, the all-in-one nature of HubSpot can be overwhelming and unnecessarily complex. 

Pipedrive

If you want to close more deals faster, you need a CRM that’s intuitive and built for efficiency. Pipedrive is designed with agencies in mind, combining pipeline visibility, smart automation, and lead generation into one seamless platform.

It’s incredibly easy to use, with a kanban-style dashboard that lets you visualize every stage of the buyer’s journey, move deals forward, and customize fields for client-specific details. Importing data is quick, and you can track detailed contact histories, link products or services to deals, and sync all client communications in one place.

You also get AI-powered features like automated lead nurturing, follow-up prompts, and forecasting tools to help your team focus on the right prospects at the right time.

The optional LeadBooster add-on includes Chatbot, Live Chat, Prospector, and Web Forms, all working together to capture and qualify leads. Combined with built-in scheduling, lead scoring, and automatic assignment, Pipedrive makes managing your funnel simple while enhancing the end-to-end client experience.
