7 Best B2B Sales Tools Under $100/Month (2025 Guide)

1) What Are Sales Intelligence Tools?

Before we get into specific tools, let's be clear on what we're comparing.

A sales intelligence tool is software that helps sales teams find, verify, and contact potential customers. These platforms provide data like email addresses, phone numbers, and company information. They pull together contact info, company data, and sometimes behavioral signals to help you build targeted prospect lists.

The sales intelligence market hit $4.4 billion in 2024 according to Fortune Business Insights. It's projected to reach $10.25 billion by 2032. There's a reason for that growth: 78% of companies now use AI in at least one business function (Outreach). Sales teams are relying more on data to work smarter.

Typical features you'll find across these B2B sales tools under $100:

• Contact databases (emails, phone numbers, job titles)
• Chrome extensions for LinkedIn enrichment
• CRM integrations (HubSpot, Salesforce)
• Email verification
• Search filters by company size, industry, and role

The big question isn't whether you need one of these affordable sales intelligence tools. It's which approach actually works for your sales process. (We've seen teams pick the wrong tool and waste months. Don't be that team.)

2) Data vs. Intent: Two Approaches to Sales Intelligence

Here's where most comparison articles miss the point. They rank tools by database size and features. But there are two fundamentally different approaches to sales intelligence. And understanding this changes everything about which tool you should choose.

Data-Quantity Tools

Most tools in this space compete on one thing: how many contacts they have.

Apollo claims 275 million. RocketReach says 700 million. These platforms give you access to massive pools of contact data. You get emails, phone numbers, and company info. Search by filters, export your list, and start outreach.

The strength here is volume and coverage. Need to reach CFOs at mid-market SaaS companies? You'll find thousands of them. The trade-off? Those leads are still cold. They've never heard of you. They've never engaged with your content. And they probably weren't thinking about your solution when you hit their inbox.

We learned this the hard way. When we first started testing these tools, we assumed bigger database = better results. Wrong.

Intent-Based Tools

The second approach flips the model. Instead of giving you more contacts, intent-based tools help you find better ones.

Intent data is information about a prospect's buying interest based on their online behavior, content engagement, or social interactions. These tools identify prospects who are actively showing buying signals. That means engaging with competitor content, commenting on industry discussions, or liking problem-aware posts.

Most budget sales tools on this list compete on database size. But there's another approach: intent-based tools like Guffles focus on finding warm leads through engagement signals. Instead of giving you more contacts, they give you better ones.

The numbers back this up. According to Search Engine Journal, warm leads convert at 14.6% compared to just 1.7% for cold leads. That's an 8.5x improvement. Factors.ai research shows intent-driven leads convert at 2-3x the rate of traditional leads.

Smaller pool, but much warmer water.

3) 7 Best B2B Sales Tools Under $100: Full Comparison

We tested each of these tools so you don't have to guess. Every tool has a legitimate use case. And we'll be upfront about limitations too. No affiliate bias here.

The 7 best B2B sales tools under $100/month are:

1. Apollo.io ($49-149/user)
2. LinkedIn Sales Navigator ($79-149)
3. Lusha ($29-51)
4. Guffles ($79)
5. Hunter.io ($34-99)
6. Kaspr ($49-79)
7. RocketReach ($69-119)

1. Apollo.io - $49-149/user/month

Category: All-in-One Sales Platform | Approach: Data-quantity

Apollo combines a massive contact database with built-in outreach tools. You can find prospects, enrich data, and send email sequences all in one platform.

Key features: 275M contacts, 60M companies, email sequencing and automation, CRM integrations (Salesforce, HubSpot), Chrome extension, AI lead scoring.

Best for: Startups and SMBs who want everything in one platform without paying for multiple tools.

Limitation: The credit system can limit heavy users, and real-world data accuracy runs closer to 80-85% rather than the claimed figures. No seat reductions mid-contract either. We burned through credits faster than expected during our tests.

Verdict: Best overall value for teams who want combined data and outreach capabilities.

2. LinkedIn Sales Navigator - $79-149/month

Category: LinkedIn Prospecting | Approach: Data-quantity (LinkedIn-specific)

Sales Navigator gives you advanced search access to LinkedIn's 1 billion+ user database, plus InMail credits and lead recommendations.

Key features: Advanced LinkedIn search filters, 50 InMails per month, 10,000 saved leads, lead recommendations, real-time insights.

Best for: LinkedIn-focused B2B sales professionals who live on the platform. If you need more LinkedIn strategies, check out our 15 LinkedIn lead generation tips.

Limitation: Here's the catch: you can't export email addresses or phone numbers directly. You'll need another tool for contact data, which means paying twice.

Verdict: Unmatched LinkedIn search, but factor in the cost of adding contact enrichment tools. A Forrester study found Sales Navigator delivers 312% ROI over three years.

3. Lusha - $29-51/month

Category: Contact Enrichment | Approach: Data-quantity

Lusha keeps it simple: a Chrome extension that pulls contact data as you browse LinkedIn profiles.

Key features: Chrome extension for LinkedIn, direct dial phone numbers, email verification, CRM integrations, team credit sharing.

Best for: Individual sales reps who need quick contact lookups without the complexity of a full platform.

Limitation: Credits add up fast. Phone number lookups cost 10x more than email credits, so costs can spiral if you need direct dials.

Verdict: The simplest and most affordable entry point for basic contact enrichment.

4. Guffles - $79/month

Category: Intent-Based Lead Discovery | Approach: Intent-based

Guffles takes a different approach entirely. Instead of giving you a database of cold contacts, it finds people who've already engaged with relevant content - liked competitor posts, commented on industry discussions, shared problem-aware content. This is essentially ethically finding leads from your competitors' audience.

Key features: Extract engagers from LinkedIn posts, filter by ICP criteria (title, company size, industry), export warm leads with contact info, engagement signal identification.

Best for: SDRs, founders, and recruiters who want warm leads showing actual buying signals instead of cold contact data.

Limitation: Currently LinkedIn-focused. Twitter, Instagram, and Reddit integration is coming, but not here yet. It's also a newer platform compared to established players.

Here's the thing about traditional sales intelligence: you get contact data, but you're still sending cold messages to strangers. Guffles flips this by finding people who've already engaged with relevant content. At $79/month (with $150 in free credits to start), it costs less than most tools on this list but delivers warmer leads. Search Engine Journal data shows warm leads convert at 14.6% compared to 1.7% for cold - that's the difference between working harder and working smarter.

Verdict: The only tool in this list focused on engagement signals over raw database size.

5. Hunter.io - $34-99/month

Category: Email Finder | Approach: Data-quantity (email-specialized)

Hunter specializes in one thing: finding and verifying email addresses. It's simple, accurate, and focused.

Key features: Domain email search, email verification, cold email campaigns (up to 2,500 recipients), AI writing assistant, Chrome extension.

Best for: Freelancers and marketers running email-only campaigns who don't need phone numbers.

Limitation: Email-only. If you need phone numbers, you'll need a second tool. The database is smaller than full platforms.

Verdict: Best-in-class email finding accuracy at an affordable price point.

6. Kaspr - $49-79/month

Category: LinkedIn Enrichment | Approach: Data-quantity

Kaspr is a LinkedIn-focused enrichment tool with particularly strong European data coverage.

Key features: LinkedIn Chrome extension, phone number extraction, email finder, CRM integrations (HubSpot, Salesforce, Pipedrive), unlimited B2B emails on free plan.

Best for: European-focused SDRs who prospect primarily on LinkedIn.

Limitation: US mobile data accuracy sits at just 52%. If you're selling into North America, this isn't your best bet.

Verdict: Strong for European markets, but look elsewhere for US coverage.

7. RocketReach - $69-119/month

Category: Contact Database | Approach: Data-quantity

RocketReach offers a large database with both email and phone data, plus technographic information about what tools companies use.

Key features: 700M+ profiles, multi-channel contact data, technographics, bulk lookups, integrations (HubSpot, Salesforce, Outreach).

Best for: Teams running multi-channel outreach who need both email and phone data plus tech stack information.

Limitation: Lookup limits can feel restrictive. Unused credits don't roll over, and you need the Pro plan ($99+) for phone numbers.

Verdict: Solid all-around option for multi-channel data needs.

4) Quick Comparison: All 7 Tools at a Glance

Here's the full picture in one table:

Notice something? Six of seven tools compete on database size. Only Guffles takes the intent-based approach. That's not better or worse, it's just different. The real question: would you rather have more leads or warmer leads? We think most teams are asking the wrong question entirely.

5) Which Affordable Sales Tool Fits Your Needs?

Still not sure which one to pick? Here's how we'd break it down by situation.

Choose by Company Size

Solo founder or freelancer: Start with Lusha ($29/mo) or Hunter.io ($34/mo). You don't need a full platform yet. Keep costs low while you validate your outreach process.

Small team (2-10 people): Apollo ($49/user/mo) gives you the best all-in-one value. Or try Guffles ($79/mo) if you want to test whether warm leads outperform your current cold outreach.

Growing team (10-50): Apollo or Sales Navigator for scalability. At this stage, you can afford to layer multiple tools.

Choose by Primary Need

• Maximum contacts: Apollo or RocketReach
• LinkedIn-focused prospecting: Sales Navigator or Kaspr (and learn to turn LinkedIn engagement into leads)
• Warm leads over cold contacts: Guffles
• Email-only campaigns: Hunter.io
• European market data: Kaspr
• Lowest entry cost: Lusha

The right tool depends on your workflow. Not on who has the biggest database. Trust us on this one.

6) Building Your Budget-Friendly Sales Stack (Under $120/Month)

Here's something most comparison articles miss: you don't have to choose just one tool. Smart sales teams layer complementary tools together.

We call this the Social Selling Stack. The Social Selling Stack starts with discovery, finding who's already interested, rather than starting with a cold database and hoping for the best.

The stack has four layers:

1. Discovery Layer: Find who's interested (Guffles - $79/mo)
2. Enrichment Layer: Add contact data (Apollo Free Tier - $0)
3. Outreach Layer: Send sequences (Instantly - $37/mo)
4. CRM Layer: Track pipeline (HubSpot Free - $0)

Total cost: $116/month. And you're covered from discovery to close.

The key insight? Start with discovery, not data. When you find prospects who've already engaged with relevant content, you're not cold-calling. You're following up on expressed interest. That's a completely different conversation.

Learn more about finding warm leads through social engagement signals.

The Best Tool Helps You Reach Prospects Who Respond

Look, the best sales intelligence tool isn't the one with the most contacts. It's the one that helps you reach prospects who'll actually respond.

Our recommendations:

• Best overall value: Apollo.io (all-in-one at $49/user)
• Best for warm leads: Guffles (intent-based at $79/mo)
• Best for LinkedIn: Sales Navigator ($79-149/mo)
• Best budget entry: Lusha ($29/mo)

If you want to test whether intent-based prospecting works for you, Guffles offers $150 in free credits to get started. No commitment required. You can see for yourself whether warm leads from engagement signals outperform your current cold outreach. Test it before spending anything beyond that.

Whatever tool you choose, test before you commit to annual plans. Most offer free trials or free tiers. Use them. Your response rates will tell you which approach works best for your market. That's the only metric that really matters.
