The 18 Top Seamless.AI Alternatives for Lead Generation in 2025

What it does better than Seamless

• Lindy integrates with People Data Labs, a robust business intelligence database with over 400 million contacts’ information. Yet, you’ll also be able to create agents that scrape the web for lead information you tell them to find. 

• The platform’s capabilities exceed Seamless's because Lindy lets you build agents that can organize the data you find with your third-party apps. You can send this information to a Google Sheet, Airtable database, or with a CRM platform like HubSpot, or Salesforce, all via Lindy’s integrations. 

• But Lindy’s not done with that data you’ve organized just yet: You’ll be able to create agents who can contact each lead via email, text message, or phone. Your agents can be set up to gather information from your leads, and further enrich your lead database with it. 

• Your Lindies can schedule meetings with leads and your reps, allowing them to pick a time with a Google Calendar or Calendly integration. Once a lead has selected a time, your Lindy will notify a human rep via email or Slack. 

Ideal Users

Lindy is an excellent choice for small, medium, and large organizations that are looking to free up time by automating several parts of their funnels. 

Pricing

Lindy has a free version that lets you create up to 400 automations per month. The lowest tier starts at $49/month, cheaper than Seamless’s lowest tier by nearly $100, and provides up to 5,000 monthly automations. Companies in need of more automation might want to check out Lindy’s $299/month version, which has about 30,000 automations. 

The Bottom Line

Lindy is an ideal Seamless alternative for automating workflows around every part of your funnel. You can create your own workflows without coding using Lindy’s simple drag-and-drop interface and prebuilt agent templates. Ultimately, using Lindy is more like onboarding a new teammate than setting up another tool.
