ContactOut vs Stirista: Why This Comparison Doesn't Work - and What You Actually Need
Why You're Comparing These Two
Here's the thing: the ContactOut vs Stirista comparison exists because of an acquisition, not because these tools compete. Stirista acquired Customer Portfolios in April 2023, and ContactOut's company directory lists "Customer Portfolios - A Stirista Company" email formats. That's the entire connection. We've seen this confusion come up repeatedly in prospecting communities, and it makes sense on the surface - both names show up when you're researching B2B data tools. But ContactOut is a sales prospecting contact finder. Stirista is an identity-driven marketing platform with a DSP, ESP, and CDP. Different buyers, different budgets, different universe.
The 30-Second Verdict
Use ContactOut if you're an SDR or recruiter who needs prospect emails and phone numbers. Plans run $99-$199/mo.
Use Stirista if you're a marketing team running programmatic display, CTV campaigns, or large-scale email sends through an identity graph. Starts at $5,000/mo.
Skip both if you want verified prospect emails without accuracy problems or hidden fair-use caps.
What ContactOut Actually Does
ContactOut is a contact-finding tool - Chrome extension plus search portal - for emails and phone numbers. It covers 350M professionals from 40M companies, and sales teams and recruiters commonly use it for fast lookups and list building.
The free tier gives you 5 emails, 5 phones, and 5 exports per day. Paid plans start at $99/mo for email only or $199/mo for email plus phone. Team and API plans require contacting sales, and that's where you'll typically see Salesforce and ATS integrations unlock.
Now the catch. ContactOut email accuracy sits around 70-75% in third-party comparisons we've reviewed. That means roughly 1 in 4 emails bounces. And while the tool works well for quick lookups, plans marketed as "unlimited" still come with fair-use caps of roughly 2,000 emails and 1,000 phone numbers per month - a detail that's easy to miss until you hit the wall. It's a lookup tool, not an identity activation platform, so you won't get a DSP/ESP/CDP stack for omnichannel campaigns. If you're trying to protect deliverability while scaling, pair any finder with an email deliverability playbook and an email bounce rate benchmark.
ContactOut's fair-use caps and 70-75% accuracy mean bounced emails and burned domains. Prospeo delivers 98% email accuracy across 300M+ profiles with a 7-day data refresh - no hidden caps, no annual contracts. At ~$0.01/email, you pay less and connect more.
Stop bouncing 1 in 4 emails. Get data that actually connects.
What Stirista Actually Does
Stirista operates in a completely different category. Founded in 2009 with about 100 employees, the company has made 7 acquisitions as it expanded its identity-driven marketing stack.
The core product is OMNA, a real-time identity graph mapping individuals across devices, IPs, and households. Stirista claims access to 26M+ businesses and reach across 100M+ households, plus 30K+ ready-made audience segments for activation. On top of that, Stirista runs AdStir (a CTV-centric DSP), an owned ESP that delivered 1.8B+ emails in 2024, and a CDP for lifecycle marketing.
OMNA carries a 4.6/5 rating on G2 from 28 reviews, though the Stirista listing on Capterra shows 0 reviews - which tells you this isn't a tool sales teams evaluate the same way they evaluate prospecting databases. Pricing starts at $5,000/mo on a usage-based model with no free trial. If you're an SDR looking for prospect emails, Stirista simply isn't built for you.

B2B contact data decays 20-30% per year. Whichever tool you pick, quarterly data hygiene is the minimum. If you're cleaning lists at scale, consider adding data enrichment services and a lightweight lead enrichment workflow.
Which One Do You Need?
