Altss vs Finder.io: Why This Comparison Doesn't Work (and What to Use Instead)
If you're comparing Altss to Finder.io, you're putting a $15,500/year LP intelligence platform next to a $9.99/month email finder that's already shutting down. These tools don't compete. They don't even occupy the same category. Altss helps fund managers find institutional investors. Finder.io helped salespeople find email addresses. One costs more than a used car; the other cost less than a Netflix subscription.
Let's sort this out quickly so you can get to the tool you actually need.
30-Second Verdict
What Is Altss?
Altss is a private-markets intelligence platform built for capital formation teams. The database covers 9,000+ family offices, 30,000+ institutional investors, 150,000+ HNWIs, 40,000+ RIA and wealth firms, and 1.5M verified LP-side contacts - all re-verified within 30 days. The whole thing runs on OSINT-powered fundraising intelligence, with continuously updated mandate signals and decision-maker contact data.
Pricing sits at roughly $15,500/year per seat based on directory data and Altss's full LP coverage license. That's steep for a solo GP, but competitive against Preqin ($12K-$81K/year, acquired by BlackRock in early 2025) or PitchBook ($20K-$70K/year). G2 reviewers give it 5.0/5 and specifically call out that the contact info actually works, unlike PitchBook and Preqin where "a lot of emails bounce." That matters more than most buyers realize - contact data decays 20-30% annually, so a 30-day re-verification cycle is a genuine differentiator in this space. We've seen similar decay rates across B2B data broadly, and it's the single biggest reason outreach campaigns fail before they start.
What Was Finder.io?
Finder.io was an email finder from 500apps offering 430M+ business emails, bulk verification, and a Chrome extension. Plans ran $9.99-$14.99/month with a 4.6/5 on G2 across 10 reviews.
Here's the thing: it's gone. 500apps announced a full wind-down of its product suite, pivoting toward 500agents, a conversational AI platform. The domain now shows a sunset notice. If you're a current user, export your data via support@500apps.com while you still can.
Finder.io shipped unverified data before it shut down. Prospeo runs a 5-step verification process across 143M+ emails - 98% accuracy, 7-day refresh, bounce rates under 4%. Start with 75 free emails. No credit card, no contract.
Your old email finder is gone. Your replacement is already verified.
Side-by-Side Comparison
These tools serve entirely different buyers, so we've added a third column - an active email finder - to give the comparison practical value.

Which One Do You Actually Need?
Use Altss if you're raising capital from family offices or institutional LPs. Compare it against Preqin, PitchBook, or Dakota - those are its real competitors. Don't waste time evaluating email finders for this job.
Skip both if you're building outbound email lists for sales. You don't need an LP database, and Finder.io no longer exists.
Look, most people landing on this comparison are sales reps who typed the wrong query. If your average deal is under six figures, you have zero reason to look at Altss. Get an email finder and move on.
What to Use Instead of Finder.io
For the email-finding use case Finder.io served, Prospeo is the most direct replacement - 143M+ verified emails at 98% accuracy, refreshed every 7 days, with a free tier of 75 emails per month. No contracts, no annual lock-in. The Chrome extension (40,000+ users) finds verified contacts from any website in one click, and CRM enrichment returns 50+ data points per contact at a 92% API match rate. In our testing, bounce rates consistently stay under 4%, which is a world apart from the unverified data Finder.io was shipping toward the end.
Hunter.io remains solid for domain-level email search. RocketReach gets recommended often in cold email communities on Reddit for its accuracy on individual lookups. Either works as a secondary option depending on your workflow.
If you’re comparing tools mainly on verification quality, start with email verification benchmarks and workflows before you buy.
Altss re-verifies LP contacts every 30 days because stale data kills fundraising. The same logic applies to sales - except Prospeo refreshes every 7 days across 300M+ profiles at ~$0.01/email. That's 98% email accuracy without the $15K price tag.
Fresh data shouldn't cost more than a used car.
