Prospecting is the process of identifying, researching, and connecting with potential B2B clients who match your ideal customer profile.
Sounds relatively simple, right? Find the right companies, reach out with personalized messaging, and book meetings. But prospecting for high-value B2B clients can get complicated fast as your agency scales.
- Maybe you-re drowning in lead databases, but can-t identify which enterprise accounts are actually ready to invest in agency services
- Maybe you-re sending personalized cold emails one by one to C-suite executives, and wasting hours you should spend closing deals
- Maybe you-re reaching the right companies but missing the context (recent funding, tech stack changes, hiring surges) that makes your pitch relevant to their strategic priorities
The right prospecting tools solve these problems by combining lead intelligence, outreach automation, and data enrichment in ways that help agencies work smarter, not harder.
In this article, we-re sharing five prospecting tools that help agencies close high-value B2B clients more consistently.
1. Instantly SuperSearch
Instantly is a cold email and lead prospecting platform that helps agencies do several things at once: find verified decision-makers, automate personalized outreach campaigns, and monitor which prospects are engaging with your emails.
Its lead prospecting feature is fittingly called SuperSearch because it gives you access to over 450 million verified B2B contacts. You can narrow down this database using 13 advanced filters to find leads that match your ideal customer profile in just a few clicks.
Our favorite feature is the data enrichment. Instantly pulls information from 14 different sources to give you context about each prospect: recent job changes, funding rounds, tech stack updates. This helps you craft outreach that speaks directly to what-s happening in a prospect-s business right now.
SuperSearch also helps you find the right prospects at the right time with:
- Lookalike prospecting that analyzes your best clients and surfaces similar companies automatically
- News filters that flag prospects who just raised funding or hired new executives, which gives you perfect timing for outreach
- Multi-provider verification that validates lead quality using 7+ data sources to ensure you-re contacting real decision-makers
Once you-ve built your list, it plugs directly into your Instantly campaigns, where you can personalize emails at scale using merge tags for prospect-specific details. From there, AI Copilot then handles sequence optimization based on your performance data. With unlimited email accounts included, agencies can run separate campaigns for each client without worrying about sending caps or additional fees.
2. ZoomInfo
ZoomInfo is a B2B sales intelligence platform that gives agencies access to detailed company and contact data for high-value prospecting. The platform maintains one of the largest B2B databases, with information on millions of companies and decision-makers. You get direct dial phone numbers, verified email addresses, and organizational charts that show you who reports to whom. This is particularly useful when selling to enterprise clients where you need to reach multiple stakeholders across departments.
What is particularly helpful is that ZoomInfo tracks intent data: buying signals like website visits, content downloads, and technology changes that show you which companies are actively researching solutions in your category. So, instead of cold outreach to every company that fits your ICP, you can prioritize accounts showing active buying intent.
It-s worth noting that ZoomInfo comes with a significant price tag and typically requires an annual contract. The platform is designed for agencies with dedicated sales teams and higher contract values, where the cost per lead is justified by deal size.
3. Prospeo
Finding decision-maker contact information on LinkedIn often means copy-pasting into multiple tools. Prospeo streamlines this by extracting verified emails and phone numbers in a few clicks.
The Chrome extension is the main way most agencies use Prospeo. You can pull emails and mobile numbers directly from LinkedIn profiles, company websites, or search results without leaving your browser.
The bulk processing is especially useful for agencies managing multiple client campaigns. Prospeo lets you upload spreadsheets or export up to 5,000 contacts daily from Sales Navigator, then enriches those records with up to 45 data points: job titles, company info, time zones, and more. This makes it easier to personalize outreach across different regions or tailor messaging based on role and seniority.
Once you-ve verified your contacts, you can export them directly into your CRM or cold outreach platform. Since Prospeo focuses specifically on finding and verifying contact information, it pairs well with tools like Instantly for the actual campaign execution.
4. Better Contact
LinkedIn gives you names and job titles, but not always email addresses or phone numbers. Better Contact fills that gap by connecting to 20+ premium data sources, including Apollo, Hunter, and RocketReach, to find verified contact information for prospects.
Instead of checking each source manually, the platform-s BetterAI algorithm automatically determines the best data source sequence for each contact and retrieves the most accurate information available. Before you export any contacts, Better Contact filters out catch-all emails and verifies every address so you-re only paying for valid, usable contacts.
If you-re running cold calling campaigns alongside email outreach, the tool can also provide phone numbers when available. Each mobile number goes through multiple verification steps, like geo-matching and activity scoring, to ensure accuracy.
The tool integrates natively with popular CRMs and outreach platforms like Clay and HubSpot, plus over 1,000 apps through Make.com. This means you can enrich contacts directly inside your existing workflow rather than exporting and importing lists between tools.
5. Clearbit
If you-re getting inbound leads but can-t tell which ones are worth pursuing, Clearbit automatically identifies high-value prospects as they interact with your website or enter your CRM.
With Clearbit, the qualification process becomes largely automated. It specializes in real-time enrichment—when someone fills out a form with just their email address, Clearbit instantly appends their job title, company size, revenue, tech stack, and other firmographic data. This happens in the background, so you can route enterprise leads to senior sales reps while they-re still warm.
The “reveal” feature is one of the most useful for agencies targeting high-value accounts. Clearbit can identify which companies are visiting your website even before they fill out a form. You get details like company name, size, industry, and estimated revenue, which helps you prioritize outreach to accounts that actually match your ideal client profile.
The platform integrates directly with popular CRMs like HubSpot and Salesforce, plus marketing automation tools like Marketo. This means enrichment happens automatically in your existing workflow without manual exports or imports.
