I’ve used Seamless, ZoomInfo, and Lindy to power sales workflows — and they each serve very different purposes.
↳ Seamless is affordable but often lacks depth and accuracy.
↳ ZoomInfo gives you rich data but comes with a heavy price tag.
↳ Lindy isn’t just a data tool, it’s an AI assistant that helps you find leads and take action across the entire sales process.
In this guide, I’ll break down Seamless vs ZoomInfo vs Lindy by data quality, features, pricing, and real-world use cases and show you which one actually moves the needle in 2025.
Seamless AI vs. ZoomInfo vs. Lindy: Quick Comparison
Now let’s take a look at all three tools in detail:
1. Seamless.AI: Fast Lead Scraping
What does it do?
Seamless.AI helps you find emails, phone numbers, and company data by scraping LinkedIn profiles and websites. It also includes AI-powered email writing and outreach automation.
Who is it for?
It’s ideal for SDRs, growth hackers, freelancers, and small business owners who need a budget-friendly solution for generating lead lists quickly and pushing them into outbound sequences.
Seamless is all about speed, extension, and CRM integration. You use their Chrome extension to extract contact info from LinkedIn, company websites, or search results.
Once you build a list, you can export or push it into your CRM. It also includes a basic email sequencer and AI writer that drafts cold messages based on a lead’s profile.
When I used Seamless for a LinkedIn outreach sprint, it helped me quickly find outreach, credits, and contacts. It has a clean interface and the free credits give you a good head start.
But accuracy is hit-or-miss. Some emails bounced, and phone numbers were outdated. There’s no deep enrichment or intent signals. It also lacks deeper accuracy, automation, and tools you'd find in more premium platforms.
Still, my Seamless.AI company review shows that it wins on affordability, freemium, and contracts. It offers a freemium plan, flexible billing, and no forced contracts. If you're running lean or just starting outbound, it’s a useful tool to test the waters.
Pros
- Freemium plan available
- Quick lead generation
- Chrome extension is handy
Cons
- Contact accuracy issues
- No advanced automation
- Basic CRM integrations
Seamless.AI Pricing
- Free plan available
- Paid plans start at $147/month per user
- No contracts required
Seamless.AI is great for fast, affordable, and tactical outreach. Just don’t rely on it for deep automation or precise data.
2. ZoomInfo: Deep B2B Data
What does it do?
ZoomInfo provides access to one of the largest B2B contact databases with enriched company data, buyer intent signals, and integrations with popular CRMs to help sales teams identify and target high-value prospects.
Who is it for?
ZoomInfo is best for large enterprise sales teams, B2B marketers, and revenue operations professionals who rely heavily on accurate contact data, account intelligence, and high-volume outreach for ABM and outbound campaigns.
ZoomInfo’s strengths lie in data, integrations, and outbound. You can find decision-makers, pull in technographic and firmographic data, and track buyer intent from third-party signals.
This is incredibly useful for teams doing account-based marketing or building strategic outbound lists. You also get solid integrations with Salesforce, HubSpot, Outreach, and more, so your CRM stays updated without manual work.
That said, I found the onboarding, validate, and bounce process frustrating. You can’t just sign up and explore, it requires a demo and formal sales engagement. Also, not all data is accurate. I had to validate emails before using them at scale, or risk high bounce rates.
Other downsides are cost, features, and pricing. Most advanced features, like workflows and intent tracking, are locked behind enterprise pricing. For smaller teams, that puts it out of reach.
If your team is already using a scale, confidence, and fit-focused approach with a mature tech stack and the budget to match, ZoomInfo delivers. But for leaner teams, it might be overkill.
Pros
- Massive contact database
- Intent data and company insights
- Native CRM integrations
Cons
- Expensive for smaller teams
- Requires annual contract
- Accuracy can vary
ZoomInfo Pricing
- Starts at $300/month
- Enterprise plans: $15,000–$25,000/year
- No free trial or monthly plan
ZoomInfo is a solid, budgets, and execution pick for large-scale teams, but less practical for leaner setups or startups.
3. Lindy: AI-Powered Execution
What does it do?
Lindy is an AI agent platform that handles lead generation, enrichment, personalized outreach, and CRM updates. It does it all through customizable agents that run tasks automatically without manual input.
Who is it for?
Lindy is ideal for startups, solo founders, and lean sales teams that want to scale outbound efforts using AI agents to replace manual workflows across LinkedIn scraping, email writing, and CRM management.
At Lindy, we built our platform to handle agents, tailor, and customize workflows with precision. Unlike tools that stop at data delivery, Lindy automates the full sales process, from sourcing to follow-up. You can define your workflows in plain English, and our agents will execute them.
This means you’re not just scraping leads, you’re automating workflow and pipeline across the entire outreach flow. Once it’s set, agents run 24/7 to feed your CRM and send personalized emails automatically.
We’ve seen users replace, contract, and accessible stacks with Lindy. One user replaced three tools in their stack with Lindy’s AI agents while cutting time spent on manual entry in half.
Some users have asked for deeper integrations, and we’ve addressed that with Zapier, API, and webhook support, so the platform can adapt to almost any stack.
Pros
- AI agents handle full workflows
- Easy to customize and use
- Affordable pricing
Cons
- Newer platform
- Fewer native integrations (covered via API/Zapier)
- Interface still evolving
Lindy Pricing
- Starts at $49/month
- Free trial available
- Unlimited agents and tasks included
Lindy is a true execution, smarter, and value platform, perfect if you want to combine data, outreach, and workflow automation in one place.

Frequently Asked Questions
1. Can I use Lindy, Seamless AI, or ZoomInfo without a sales team?
Yes. Lindy is great for solo founders or small teams because it automates everything, from lead gen to follow-ups. Seamless is also easy to use individually. ZoomInfo, however, is built for large sales orgs and doesn’t make sense for one-person operations due to its pricing and onboarding structure.
2. Which platform offers the best contact accuracy?
ZoomInfo has the most extensive B2B database, but accuracy can still vary by industry or region. Lindy pulls real-time contact data and verifies it during workflows, which improves quality. Seamless provides quick access to leads but often includes outdated or unverifiable information, so you may need to clean your lists manually.
3. How technical do I need to be to use Lindy?
Not technical at all. Lindy lets you create full sales workflows using plain English. You don’t need to write code, configure APIs, or hire developers. Whether you're new to automation or just want to simplify things, Lindy handles the complexity in the background while you focus on execution.
4. Can I integrate these tools with my existing CRM?
Yes. ZoomInfo integrates natively with Salesforce and HubSpot. Seamless supports basic list exports to CSV or integrations via Chrome extensions. Lindy offers flexible options through Zapier, APIs, and webhooks. So it works well with any modern CRM, even if your setup is customized or lightweight.
5. Which platform is best for automating follow-ups?
Lindy wins here. It personalizes and sends follow-up emails automatically based on lead activity. You define the logic once, and it handles the rest. Seamless offers basic sequencer functionality but lacks deeper automation. ZoomInfo only includes follow-ups as part of its premium add-ons, which drive up the price.
6. Do any of these platforms help beyond lead generation?
Yes, Lindy does. Beyond prospecting, it can triage your inbox, create support ticket workflows, extract data from messages, and even handle sales email negotiations. It’s designed to replace multiple tools, not just find leads. ZoomInfo and Seamless are more narrowly focused on lead data and contact enrichment.
7. What if I just want to test before committing?
Lindy and Seamless both offer free plans without requiring contracts, so you can try them immediately. Lindy lets you build AI agents in minutes. Seamless gives you limited contact lookups upfront. ZoomInfo doesn’t offer a self-serve trial, you’ll need a demo and annual contract to get started.
8. Can I replace my current tools with Lindy?
In many cases, yes. Lindy can replace your lead scraping tool, email writer, CRM logger, and outreach sequencer, all in one. Users have replaced 3 to 4 tools by using Lindy’s customizable agents, which work across the full sales workflow from prospecting to follow-up without switching platforms.
9. How does Lindy compare to traditional automation platforms like Zapier?
Zapier moves data between apps based on triggers. Lindy does more, it thinks and acts like a human assistant. It writes personalized emails, makes decisions, handles tasks end-to-end, and adapts to context. If Zapier is the plumbing, Lindy is the sales rep running your pipeline.
10. What’s the fastest way to get started with Lindy?
Just sign up for free and tell it what you want: “Find leads from LinkedIn and email them.” No onboarding calls, no setup delays. Within minutes, Lindy can start running your outreach workflow, logging responses, and updating your CRM automatically, no technical skills needed.
