Adapt.io vs Stirista: Different Tools, Different Jobs - Here's What to Pick
Someone on your team dropped both names in a Slack thread, and now you're stuck comparing them. Here's the thing: Adapt.io and Stirista aren't competitors in any meaningful sense. One is a self-serve B2B contact database for sales reps pulling prospect lists. The other is an enterprise identity resolution and activation platform built for marketing teams running CTV and programmatic campaigns - a completely different animal with a completely different buyer.
The audience intelligence platform market hit $8.2B in 2025 and is growing at 15.3% CAGR. Stirista lives there. Adapt.io lives in sales intelligence. Let's sort this out so you don't waste a quarter evaluating the wrong tool.

Adapt.io - What You Get
Adapt.io is a straightforward B2B contact database. You search by company, title, industry, or location, pull emails and phone numbers, and export to your CRM. Nothing fancy, nothing confusing.
Pricing is credit-based:
- Free ($0/mo): 25 email credits, 25 enrichment credits, 25 contacts/day, Chrome extension, advanced filters, email support
- Starter ($49/mo): 500 email credits, 500 enrichment credits, 50 contacts/day, CSV export, saved search alerts, ABM list building
- Basic ($99/mo): 1,000 email credits, 100 phone credits, 1,000 enrichment credits, 100 contacts/day, CRM export, basic reporting
- Custom (quote): Suppression lists, job-change alerts, team management, API access, dedicated AM, no daily contact limit
G2 averages show about 4 months to implement and 16 months to ROI. That ROI timeline is telling - credit limits can genuinely slow teams down before they see full value, especially if you're running outbound for more than a handful of reps.
On Reddit, practitioners describe Adapt.io as having solid reviews in enterprise email finder discussions, and G2 sentiment backs that up: ease of use dominates the praise (71 mentions) while contact quality gets decent marks (59 mentions). The flip side? Limited credits are the #1 complaint (34 mentions), and incorrect emails pop up occasionally (14 mentions). Phone numbers don't unlock until the $99 Basic plan. For heavy-volume prospecting, you'll hit credit walls fast.
Stirista - What You Get
Stirista's big differentiator is that it's the only data-driven company that also owns both an ESP and a DSP. That means they can resolve identity and activate campaigns without relying on third-party ad tech for execution - a rare vertical integration in this space.
The core product, OMNA, is a real-time identity resolution platform built around three graphs:
- ABM Graph - B2B audiences at work and home
- Viewership Graph - CTV viewership across devices
- IP/Device Graph - tying connected devices to an individual
Pricing isn't public. The best anchors come from marketplace listings: data products start at roughly $5,000 minimum, enterprise packages commonly range from $5,000/month up to $160,000/year, and digital audience segments run $0.75-$1.50 CPM. Stirista was founded in 2009 and raised $13M in growth equity.
Users praise the support team and dashboard intuitiveness. The cons? Reporting automation gaps and occasional sync issues. Look - if you're a sales rep looking for prospect emails, Stirista simply isn't built for you. But if you're a marketing director running cross-channel campaigns with identity-based targeting, it's a serious option worth evaluating.
Which One Should You Pick?
We've seen this pattern before: most people landing on an Adapt.io vs Stirista comparison are actually looking for B2B contact data for outbound, and neither tool is the best answer for that specific need.
Pick Adapt.io if you're an individual rep or small sales team doing outbound on a budget. You need emails, maybe some phone numbers, and you want to be searching within five minutes of signing up. It does that job well enough, though the credit caps will frustrate you once volume picks up.
Pick Stirista if you're an enterprise marketing team running identity-driven campaigns across CTV, display, and programmatic email, and you need an identity graph that resolves across devices and households. Skip it for anything resembling traditional outbound sales.
Skip both if you need verified B2B emails and direct dials without credit caps or a $5K/mo commitment. In our experience, most teams comparing these two tools actually need something in between - high-accuracy contact data at scale without enterprise pricing or daily export limits strangling their workflow.
