Signado vs Apollo
The Apollo.io alternative that finds the leads for you
Apollo gives you 275+ million contacts to filter through. Signado finds warm leads in your market every day: people publicly commenting on LinkedIn posts about your category, your competitors, and the topics your buyers care about. ICP-scored, ready for your next action.
What Apollo gets right
Apollo is the default contact database for B2B sales teams, and for good reason. A database of 275+ million contacts with 65+ search filters lets you build targeted lists by job title, seniority, industry, company size, and technology stack in minutes. The Chrome extension pulls contact data directly from LinkedIn profiles without switching tabs. Built-in sequences handle multi-step email outreach with automated follow-ups, and native CRM integrations push data into Salesforce and HubSpot without manual imports.
The free plan is usable: 1,200 credits per year with access to the core prospecting and sequencing features. Paid plans start at $49/user/month billed annually. Over 500,000 companies use Apollo. It solved the contact sourcing problem.
The question it doesn't answer: out of those 275M contacts, which ones actually want to hear from you this week?
Where filtering a database breaks down
Apollo's database refreshes quarterly at best. In practice, contact data decays at roughly 30% per year: people change jobs, companies restructure, email addresses go stale. A list exported in January is measurably less accurate by April.
The deeper problem is qualification. Apollo gives you no mechanism to tell who's actually commenting on topics in your market right now.
Your list says Sarah is VP of Sales at Company X. What it doesn't say is that Sarah commented on a competitor's post last Tuesday about a problem your product solves. That comment is a behavioral intent signal. It tells you Sarah is thinking about this category today, in her own words, in public. That's the difference between an email to a cold record and an email to someone who already raised their hand.
Apollo's sequences fire on a calendar cadence: Tuesday at 9am, follow up Thursday, follow up next Monday. The timing is based on your schedule, not on anything happening in the prospect's world. The result: generic emails arriving at random moments, competing with 50 other SDRs who pulled the same list and wrote the same 'I noticed your company is growing' opening line.

What changes when discovery runs on comment signals
Without warm-lead discovery, outbound follows a predictable pattern. Pull a list of 500 contacts from Apollo. Write a 3-step email sequence. Send on a Tuesday cadence. Get 8-12 replies. Most say 'not the right time.' Repeat next month with a new list.
The list is fine. The copy is fine. But 490 of those 500 contacts had no reason to care about your email that week.
With Signado, the workflow changes. Tell Signado your ICP. Add a few keywords your buyers actually talk about. Discovery runs every day, scanning LinkedIn for people publicly commenting on posts about your category, your competitors, or the topics your buyers care about. Each lead lands in your feed ICP-scored with a one-sentence reason. The AI drafts a reviewable opener referencing the comment.
You stop emailing 500 people hoping 10 care. You email 30 people who showed public intent this week. The reply rate changes because the relevance changed.
Don't email a ghost.
Databases like Apollo decay by ~30% every year. People change jobs, companies pivot, and budgets freeze. Signado doesn't hand you a stale list. Signado only surfaces a lead when they publicly commented on a post relevant to your market this week.
Context beats Volume.
Apollo gives you the email address. Signado gives you the reason to send it. Our AI uses the comment signal and post context to draft a specific opener referencing the thing they actually said.

The tools do different things, so the comparison isn't apples-to-apples. Apollo is a contact database: you pay for access to email addresses and phone numbers. Signado finds warm leads from LinkedIn comments: you pay for daily discovery, ICP scoring, AI-personalized messages, and Deep Dive intelligence on the accounts that matter.
A 5-person team on Apollo Professional pays $395/month for contact data with no discovery or signal layer. The same team on Signado Growth pays $349/month for warm-lead discovery on multiple keywords, ICP scoring, AI messages, email finder, and Deep Dive on any account.
Many Signado users keep Apollo for sourcing contacts on specific accounts and use Signado for warm-lead discovery. The combined cost for a 5-person team: Apollo Basic ($245) + Signado Starter ($99) = $344/month for both contact sourcing and warm-lead intelligence.
Which tool fits your workflow
Stay on Apollo if:
Your primary need is filtering a database to build prospect lists from scratch. You don't have keywords for your market or buyer audience yet, and you need access to a large contact pool to identify companies and decision-makers by industry, size, title, and technology stack. Apollo's filters and database are purpose-built for that job. If you're a solo SDR doing volume-first outbound (500+ emails per week, optimizing for top-of-funnel coverage) Apollo handles the full workflow from list building to sequencing.
Use Signado if:
Your problem isn't access to contacts. Your problem is knowing which contacts care this week and what to say to them. Your reply rates sit below 5%. Your team spends hours qualifying lists before writing a first line. Your sequences fire on a calendar with no connection to what's actually happening in the prospect's world. Signado finds warm leads from LinkedIn comments, scores them against your ICP, helps draft the opener from the actual signal, and ships through your inbox or your sequencer. You can start with zero contacts or import lists from Apollo, Clay, or CSV. Both flows work side by side.

Common questions
What's the difference between Signado and Apollo.io?
Apollo is a contact database with 275+ million profiles, offering email addresses, phone numbers, and outreach sequences. Signado is signal-driven lead generation: it finds warm leads from LinkedIn comments on topics your buyers actually talk about, scores them against your ICP, and helps draft AI-personalized messages referencing the comment. Apollo answers 'who exists?' Signado answers 'who is actually commenting on topics in my market right now, and what should I say?'
Can I use Signado and Apollo together?
Yes. Signado works with contacts from any source: Apollo, Prospeo, Clay, ZoomInfo, or a CSV export. If you already use Apollo as your contact database, you can import those contacts into Signado for ICP scoring and AI-personalized outreach. You can also use Signado entirely on its own, since discovery finds warm leads from LinkedIn comments without requiring an external contact source.
How is Signado different from Apollo's buyer intent signals?
Apollo's buyer intent feature tracks anonymous website visitor behavior: which companies visited your site. Signado tracks behavioral intent signals: who is publicly commenting on LinkedIn posts about your category, your competitors, or the topics your buyers care about. Anonymous browsing curiosity versus named, public comment context on a specific topic you sell into.
Does Signado provide contact data like Apollo does?
Signado finds warm leads from LinkedIn discovery and writes their profile data (name, title, company, headline) to your workspace as part of the discovery flow. For accounts where you want broader contact coverage beyond what discovery surfaces, Apollo (or ZoomInfo, Clay, CSV) sits alongside Signado as a contact source. They cover different ground.
Keep Apollo for sourcing. Use Signado for warm leads.
