A short list sorted by job covers most small businesses: Apollo.io for finding and emailing B2B contacts (free plan; paid from $49 a user a month), LinkedIn Sales Navigator for account research ($119.99 a month), Hunter for budget email finding, Clay for enrichment, a website chatbot for inbound leads, and ChatGPT or Claude for research.
Choose by the lead problem you actually have, not by whose AI sounds cleverest. A business with plenty of website traffic but few enquiries needs capture tools, not a contact database. A business selling to a narrow group of trade buyers needs research and verified contacts, not a high-volume sending tool. Most small firms end up with two or three tools costing between $50 and $250 a month, and the tools below are grouped so you can pick the ones that match your gap. All prices are list prices as of September 2026; lead tools change their plans often, so confirm before buying.
Match the tool to the lead problem you have
Start with this table. Find the row that describes your situation, and read only the sections it points to.
| Your situation | What's missing | Tool type | Examples below |
|---|---|---|---|
| "We don't know who to sell to beyond our current customers" | A list of matching companies | Research assistants, account research | ChatGPT, Claude, Perplexity; Sales Navigator |
| "We know the companies but not the right person or their email" | Named contacts with verified details | Contact databases | Apollo, Hunter, Lusha |
| "We have a list but it's thin: no size, no sector, no reason to call" | Enrichment and signals | Enrichment platforms | Clay |
| "People visit our site but never get in touch" | Visibility of interested companies, or a way to capture them | Visitor identification, chatbots | Leadfeeder (Dealfront); Tidio, HubSpot |
| "We have contacts but no time to write and send outreach" | Sequenced, warmed-up sending | Outreach tools | Instantly, lemlist |
If you're still deciding whether outbound prospecting is worth it at all, what actually works in AI lead generation for small businesses is the better starting point. For how to use the research tools step by step rather than which to buy, see finding B2B prospects with AI research tools.
Contact databases: Apollo, Hunter and Lusha
These tools hold millions of business contact records and let you filter by industry, company size, job title and more, then reveal an email address or phone number for a credit. They differ mainly in price per contact, how strong they are on phone numbers, and whether sending is built in.
Apollo.io: database and sending in one place
What it does. A large B2B contact database with filters, email verification, sequences (automated multi-step email campaigns), CRM sync and AI features for researching accounts and drafting personalised messages.
Price. A free plan with a small annual credit allowance; Basic $49 a user a month, Professional $79 and a top team tier at $119 (three-user minimum), all billed annually, with monthly billing costing more. Paid plans come with an annual pool of credits (30,000 on Basic). Check Apollo's pricing page for the current credit rules, because exports and phone numbers use credits at different rates.
Example. A wholesaler of cleaning supplies wants independent gyms and café groups with two to twenty sites. The saved search looks like this:
Industry: Health, wellness and fitness; Restaurants
Employees: 11-200
Job titles: Owner, Operations Manager, Facilities Manager,
Purchasing Manager, General Manager
Keywords: "multi-site", "locations", "franchise"
Exclude: existing customers (uploaded CSV of domains)
Email status: Verified only
That produces a few hundred named contacts, which the wholesaler exports in batches of fifty and checks by hand before any sending.
How to start. Use the free plan for a week to test data quality in your niche: pull fifty records for companies you already know and see how many names and emails are right.
Watch-outs. Data quality varies a lot by sector and company size; small private firms are thinner than large ones. Credits get used on exports you never contact, so export in small batches. And because sending is built in, it's easy to email too many people too fast; the deliverability rules in writing cold emails that stay out of spam apply here.
Hunter: cheap, reliable email finding
What it does. Finds and verifies email addresses from a company's domain or a person's name and company, with a smaller B2B database, simple sequences and an AI writing assistant.
Price. Free with 50 credits a month; Starter $49 a month ($34 billed annually) for 2,000 credits; Growth $149 ($104 annually) for 10,000; Scale $299 ($209 annually). Credits are shared across unlimited users, which suits small teams. Details are on Hunter's pricing page.
Example. A courier firm has a list of 40 law firms and accountancy practices near its depot from its own research. It pastes the domains into Hunter to find the office manager at each and verifies every address. Thirty-one come back verified, six come back "accept-all" (the mail server accepts anything, so the address can't be confirmed), and three have no match. The courier firm emails the 31 and phones the other nine.
Watch-outs. Hunter guesses an address from the company's email pattern when it can't find it published; treat "accept-all" and pattern-based results as unconfirmed. It's weaker on phone numbers than Apollo or Lusha.
Lusha: when you need phone numbers
What it does. A contact database and browser extension that's often used for direct phone numbers as well as emails.
Price. Free with 40 credits a month; Starter $49.90 a month (400 credits) or $37.45 a month billed annually; Professional $69.90 a month (600 credits) or $52.45 annually; Premium $399.90 a month. An email reveal costs 1 credit and a phone number 5.
Example and quick sum. A car dealership's fleet sales manager wants to call fleet managers at local firms running ten or more vans. On Professional, 600 credits buys up to 120 phone numbers a month (600 ÷ 5), or 600 emails, or a mix. If she calls 25 fleet managers a week, that's 100 numbers a month, 500 credits, leaving 100 for emails. Knowing that ratio before buying stops a surprise top-up.
Watch-outs. Direct mobile numbers raise more privacy questions than switchboard numbers, and calling rules differ by country. Check the rules where your prospects are before building a calling list.
Research tools: Sales Navigator and the chat assistants
LinkedIn Sales Navigator: finding the right person inside a company
What it does. LinkedIn's paid prospecting product, with more than 50 advanced search filters, saved lead lists, alerts when people change jobs, and AI features including Account IQ and Lead IQ (instant summaries of a company or person) and Message Assist (AI-drafted outreach, in public beta).
Price. Core $119.99 a month or $1,079.88 a year; Advanced (for teams) $159.99 a month or $1,799.88 a year; Advanced Plus by quote. See LinkedIn's plan comparison.
Example. A manufacturer of spare parts for packaging machines wants maintenance managers at food and drink plants. In Sales Navigator it filters by industry (food and beverage manufacturing), company size (51 to 500), function (engineering, operations) and titles containing "maintenance" or "engineering manager", then saves the list and switches on job-change alerts. When a maintenance manager moves to a new plant, that's a timely reason to get in touch: new people often review suppliers.
Watch-outs. Sales Navigator doesn't give you email addresses. And the browser add-ons that scrape it or automate connection requests break LinkedIn's terms and get accounts restricted. Use it to research and to message within LinkedIn, and use a contact database for emails.
Chat assistants: research you'd otherwise pay someone to do
What they do. The research modes in the main chat assistants read dozens of web pages and produce a cited report. For lead generation that means building a long list of companies that fit a profile, summarising a target account before a call, or finding a reason to get in touch now.
Price. ChatGPT Plus $20 a month; Claude Pro $20 a month ($17 billed annually); Perplexity Pro $20 a month; Google AI Pro $19.99 a month. Many businesses already have one of these.
Example: a prompt, its output and what to fix.
I sell refurbished pallet racking and shelving to warehouses.
Find 15 companies that have opened or expanded a warehouse or
distribution centre in the last 12 months in [region].
For each give: company, site, what changed, source link, date.
Only include items with a source you can link to.
Say "not found" rather than guessing.
An illustrative result lists fifteen companies, each with a news story or planning notice. Checking the links is not optional. In a typical run, two or three items turn out to be announcements of plans that never went ahead, one is a company that has since closed, and one source link points to a different article from the one described. The fix is simple: open every link, keep only what the source actually says, and ask the assistant a follow-up ("for items 3, 7 and 11, the sources don't mention an expansion; remove them"). Which assistant is best for this kind of work is covered in Perplexity versus ChatGPT for business research.
Watch-outs. Chat assistants don't hold contact databases, and when asked for a named person's email they may invent one that looks plausible. Use them for companies and reasons, not for contact details.
Enrichment at scale: Clay
What it does. A spreadsheet-like tool that pulls data from many providers into one table and runs an AI agent (Claygent) that visits websites to answer questions you set for each row, such as "Does this company sell to hospitals?" or "Which brands do they list on their site?"
Price. Free with 500 actions and 100 data credits a month (and a limit of 200 rows per table); Launch from $167 a month with 15,000 actions and 3,000 data credits; Growth from $446 a month; annual billing saves 10%. AI-heavy columns show an estimated credit cost per row before you run them.
Example. An import-export business that brings in specialist kitchen equipment has 300 distributor websites from trade-show exhibitor lists. In Clay it adds three AI columns: "Do they already stock a competing brand? Name it", "Do they sell to restaurants, hotels or both?", and "Is there a named buyer or purchasing contact on the site?" The illustrative result: 112 distributors stock a competitor (good targets, since they already sell the category), 41 sell to hotels only (lower priority), and 58 name a buyer. What took an intern two weeks takes an afternoon of checking.
Watch-outs. Clay has a real learning curve; budget a day to learn it. Credits disappear quickly on large tables, so test every column on ten rows first. And it pays off only when you have hundreds of rows to work through; for fifty prospects, a chat assistant and an afternoon will do.
Warm signals: companies already visiting your website
What it does. Visitor identification tools such as Leadfeeder (now part of Dealfront) match website visits to the companies behind them, using the network the visit came from, and show which pages they read.
Price. Leadfeeder has a free Lite plan that identifies up to 100 companies a month and shows the last seven days of data; paid plans are priced by the number of companies identified each month.
Example. A storage facility that also offers business storage sees that a regional logistics firm visited its "business storage and racking" page four times in a week, including the prices page. The manager doesn't cold-email a stranger; she sends the logistics firm's operations team a short note offering a site visit and the current business rates, and flags the company in the CRM as warm.
Watch-outs. These tools identify companies, not people, and they miss visits from home networks and mobile data, which is a growing share of traffic. They also involve tracking scripts, so your cookie banner and privacy notice need to cover them; ask your data-protection adviser if you're unsure.
Sending tools: Instantly and lemlist
What they do. Cold-email platforms that connect several sending inboxes, warm them up (send and receive small volumes of friendly mail so providers learn to trust them), rotate sending between them and run sequences with AI-written personalisation.
Price. Instantly's outreach Growth plan is $47 a month (about $37.60 billed annually) for 5,000 emails and 1,000 uploaded contacts a month, with unlimited sending accounts and warm-up; its lead database is sold separately on credits. lemlist's Email plan is $69 a month or $55 billed annually, with unlimited users and senders, 50,000 emails a month, warm-up and a contact database; its Multichannel plan, adding LinkedIn and SMS steps, is $109 per user a month or $87 billed annually.
Example: before and after an AI-personalised opener.
Before (the AI default): "I hope this email finds you well! I noticed that [Company] is a leader in the hospitality space and I'm reaching out because our innovative solutions help businesses like yours streamline operations."
After (personalised from research): "Saw that you opened a third site last month. When the cleaning cupboard doubles, most groups start ordering from three suppliers at once. We deliver weekly to twelve café groups on one invoice; would a price list for your three sites be useful?"
The second works because it contains a fact about them and one clear offer, and it would be wrong for anyone else.
Watch-outs. These tools make it very easy to send far too much. Unlimited sending accounts don't mean unlimited safe volume, and a burned domain takes weeks to recover. Start with a few dozen emails a day per inbox.
Inbound capture: chatbots and HubSpot's free CRM
Outbound tools get attention, but for many small businesses the cheapest leads are the ones already on the website. Two tools worth knowing:
- HubSpot's free CRM and chatbot builder capture chat and form leads straight into contact records at no cost, with scripted chat flows that can qualify a visitor and book a meeting. HubSpot's paid AI agents run on credits at $10 per 1,000: the Prospecting Agent uses 100 credits (about $1) per lead it recommends for outreach, and Sales Hub Starter includes 500 credits a month (Professional 3,000). Sales Hub Starter lists at $20 a seat a month, and HubSpot often runs steep first-year discounts, so check what you'll pay in year two.
- Tidio adds an AI agent (Lyro) that answers questions from your own content, and Flows that collect details and quote requests. There's a free plan; Starter is from $29 a month, less billed annually, and Lyro is an add-on from about $39 a month for 50 AI conversations.
Example. A wholesaler's website gets trade enquiries from shops wanting to open an account. A chat flow asks three questions (business type, number of sites, expected monthly spend), and anyone over a spend threshold is offered a call with the account manager that day. The design details are in adding an AI chatbot that captures leads.
A wholesaler's stack, costed
Here's a worked choice for an illustrative cleaning-supplies wholesaler with two salespeople, selling to gyms, café groups and offices. Its goal: 400 new target accounts a quarter, about 30 personalised emails a day between the two of them, and more trade-account sign-ups from the website.
| Job | Tool | Monthly cost | Why this one |
|---|---|---|---|
| Find companies and reasons to call | ChatGPT Plus (already had it) | $0 extra | Research new openings and expansions |
| Named contacts and sending | Apollo Basic, one seat, annual | $49 | Database plus sequences in one tool |
| Second salesperson's contacts | Hunter Free | $0 | 50 credits covers her smaller list |
| Warm website visitors | Leadfeeder Lite | $0 | 100 companies a month is enough to test |
| Website trade-account enquiries | HubSpot free CRM and chatbot | $0 | Leads land in the same CRM as outbound |
| Total | $49 |
What it left out, and why: Sales Navigator (their buyers aren't active on LinkedIn), Clay (400 accounts a quarter doesn't justify the learning curve), and a separate sending tool (two people at 30 a day fit inside Apollo's sequences with careful pacing).
The quick sum on whether it pays: at 30 emails a day over 21 working days, that's 630 emails a month. If three in every hundred lead to a conversation (a cautious assumption for well-researched emails; measure your own), that's about 19 conversations. If one in five becomes a trade account worth $400 a month in margin, four new accounts add $1,600 a month for a $49 tool and roughly an hour a day of each person's time. The time is the real cost, which is why comparing AI lead generation with hiring a salesperson is worth reading before you scale up.
Three stacks by budget
| Budget | Stack | Suits |
|---|---|---|
| Under $50 a month | A chat assistant subscription you have now; Hunter or Apollo free plans; HubSpot free CRM and chatbot; Leadfeeder Lite | Owner-led selling, fewer than 20 prospects a week |
| $100 to $250 a month | Apollo Basic or Professional; Sales Navigator Core if your buyers use LinkedIn; a chatbot with AI answers | One or two salespeople doing steady outbound |
| $400 a month and up | Clay Launch for enrichment; Apollo or Lusha for contacts; Instantly or lemlist for sending; Sales Navigator Advanced | A small sales team working hundreds of accounts a month |
Moving up a row only makes sense when the row below is working and the bottleneck is volume. If the cheap stack isn't producing conversations, a more expensive one usually produces more of the same non-conversations.
Run a 14-day trial with a scorecard
Most of these tools have free plans or trials. Test two in parallel on the same 50 target companies, ideally companies you already know well, so you can judge accuracy. A filled-in scorecard from the wholesaler's test (illustrative):
| Measure | Apollo | Lusha |
|---|---|---|
| Of 50 companies, how many had a matching decision-maker? | 38 | 33 |
| Of those, right person (checked on company website) | 31 | 29 |
| Emails verified | 29 | 27 |
| Bounces from a test send to 20 | 1 | 1 |
| Direct phone numbers found | 12 | 21 |
| Time to build the list | 50 minutes | 70 minutes |
| Verdict | Apollo for email-led outreach; Lusha only if phone becomes the main channel | |
"Right person" is the row most buyers skip and the one that matters most. A database full of verified emails for people who left the company last year is worse than useless.
Checks before you contact anyone
- Record the source of every contact. Add a "lead source" field in your CRM (Apollo, Hunter, website chat and so on). You'll need it to answer "where did you get my details?" and to judge which tool is earning its fee.
- Verify, then send small. Send to verified addresses only, and keep bounces under about 2%. A spike in bounces is the first sign a tool's data is stale in your niche.
- Keep a suppression list. Anyone who says no, unsubscribes or is an existing customer goes on a list you upload to every tool, so a new tool doesn't email them again.
- Know the rules for your recipients. Business contact data is still personal data under laws such as the GDPR; you need a lawful reason to use it, a clear opt-out in every message, and in some places consent for certain recipients. Ask a data-protection adviser if you're unsure where you stand.
- Don't automate LinkedIn. Connection-request bots and scrapers break LinkedIn's terms, and a restricted account costs you your most useful research tool.
Once the leads are coming in, the next problem is working out which ones to call first. That's a scoring job, and the tools you've just chosen will all export the fields you need for it.
Before you buy a lead generation tool
Is it legal to email contacts I find with these tools?
It depends on where your recipients are and whether they're individuals or businesses. Some places allow emailing business contacts with a clear opt-out; others require prior consent for many kinds of recipient. Under data-protection law such as the GDPR, a work email is still personal data, so record where each contact came from and why contacting them is justified. If you're unsure, ask a data-protection adviser before your first campaign.
Should I just buy a ready-made lead list instead?
Usually not. Bought lists tend to be out of date, shared with many other senders and weak on permission records, which drives up bounces and spam complaints and can damage your email domain. A database tool gives you filters, fresher data and verification on each record. If you do buy a list, verify every address first and send only to a small sample to test its quality.
Do I need a CRM before any of these tools?
You need somewhere single to keep leads, their source and what you've sent them, or you'll email the same person twice from two tools. HubSpot's free CRM, Pipedrive or even a well-kept spreadsheet will do at first. Most tools here connect to HubSpot and Pipedrive directly. Set up the CRM fields for lead source and status before importing anything.
How long before a new lead generation tool shows results?
Give outbound tools six to eight weeks: two for set-up and email warm-up, then four to six of steady, small-volume sending before judging reply rates. Inbound tools such as chatbots show early signals within two weeks if you have steady traffic. Judge each tool on qualified conversations and booked meetings, not on the number of contacts it exports.
