Ocean.io: Company-Level List Building
What it does
Ocean.io builds lists of companies based on advanced filters like industry, employee count, funding stage, technology stack, growth signals, and hiring trends. It's designed for TAM-level prospecting where you need comprehensive market coverage based on firmographic criteria.
When to use it
- •You need to build large account lists based on company attributes (industry, size, tech stack)
- •Your ICP is defined by firmographics (e.g., "SaaS companies with 50-200 employees using HubSpot")
- •You're running outbound to a broad TAM and need market saturation
- •You want to identify companies based on growth signals (hiring, funding, tech adoption)
The verdict
Use Ocean.io if you need comprehensive company-level prospecting with advanced filtering. It's the best tool for building TAM lists when your ICP is defined by firmographics. Skip it if you're targeting individuals based on behavior or running micro-targeted plays where company-level data isn't sufficient.
DiscoLike: Reddit & LinkedIn Scraping
What it does
DiscoLike scrapes Reddit threads and LinkedIn posts to identify prospects discussing specific topics or pain points. It pulls usernames, profile links, and context from conversations, letting you build lists of people actively talking about problems your product solves.
When to use it
- •Your ICP actively discusses problems in Reddit communities or LinkedIn groups
- •You want to reach people showing real-time buying intent through their questions or complaints
- •You're running highly personalized outreach based on specific conversations
- •You need to monitor competitor mentions or industry discussions for prospecting
The verdict
Use DiscoLike if your ICP congregates in online communities and discusses their needs publicly. It's exceptionally powerful for conversation-based prospecting with high personalization. Skip it if your ICP doesn't actively participate in Reddit or LinkedIn discussions.
Apify: Custom Data Scraping
What it does
Apify is a web scraping platform that lets you extract data from virtually any website. It has pre-built scrapers for common platforms (Google Maps, Amazon, Yelp, etc.) and supports custom scraping for proprietary data sources. You can automate data collection from sites not covered by other GTM tools.
When to use it
- •You need data from sources not available in standard prospecting tools (niche directories, forums, marketplaces)
- •Your ICP is listed on specific platforms (e.g., e-commerce sellers on Shopify app store)
- •You want to scrape competitor customer lists from public sources
- •You're building proprietary data sets that give you a competitive prospecting advantage
The verdict
Use Apify when you need data from sources other tools don't access. It's powerful for building unique prospecting lists that competitors can't replicate. Skip it if standard prospecting databases cover your ICP adequately—it's overkill for basic list building.
n8n: Workflow Automation
What it does
n8n is an open-source workflow automation platform (Zapier alternative) that connects your GTM tools through custom logic. It allows you to build multi-step workflows with conditional branching, data transformations, and integrations across your entire stack without writing code.
When to use it
- •You're running complex workflows that require custom logic (if/then conditions, data enrichment loops)
- •You need to connect tools that don't have native integrations
- •You want to orchestrate your entire GTM stack (data scraping → enrichment → sequencing) in one automated workflow
- •You're processing high volumes of data and need unlimited automation runs (unlike Zapier's plan limits)
The verdict
Use n8n if you're running sophisticated outbound operations that require custom workflow automation beyond what native integrations provide. It's essential for scaling complex GTM motions. Skip it if your workflows are simple and can be handled with native tool integrations or basic Zapier automations.
