AI Ark has accelerated our high-volume lead exports, delivering deeper enrichment at scale without sacrificing data quality. Pre-verified emails reduce bounce rates and eliminate a separate validation step, lowering operational overhead. Fast, reliable platform with a highly responsive, innovative team.

Thibault GarciaFounder @ Reachly

Since using AI Ark, pulling leads for specific accounts has become much easier and we've been able to cut a lot of the Clay processes we previously relied on to build our client's TAM. AI Ark simplifies the whole workflow, reduces manual steps, and gets us to a clean, usable list faster.

Alex VaccaFounder & CEO @ Frontal

Having a mix of the best of all worlds. With great volume when building list, being able to also then use the same platform to get great email or phone number coverage. Previously we would build list one place, find emails with 3 other tools, and validate with a 4th. AI Ark has held better results than that previous method, all in 1 tool.

Dan RosenthalCo-Founder @ Workflows.io

AI Ark is our go-to B2B database for bulk exports across TAM mapping, stakeholder mapping, and outbound list-building. With regularly updated data, we can use it with real confidence both internally and for our clients.

Alex FineCo-Founder @ Understory

AI Ark has become a key part of our tech stack, effectively replacing Apollo. We're confident bounce rates stay under 1% without any separate validation step. And exporting 100k leads is effortless, fast, stable, and reliable, so we can scale outreach without worrying about data quality.

Mitchell KellerCo-Founder & Head of Growth @ LeadGrow.ai

I ran a line-by-line comparison between Apollo and AI Ark, and AI Ark won 10 out of 10 tests. It consistently surfaced more complete, usable contact records than anyone else we tried. The lift in coverage was immediately noticeable, and it's made our prospecting faster, easier, and more reliable.

Prabesh KhanalFounder @ GrowthPal

Since switching to AI-Ark, the data quality has been genuinely impressive. Bounce rates stay low, and the 30-day refresh cycle sets it apart from most tools. It has significantly reduced our list-building time, made GTM workflows more reliable, and become our go-to platform for building outbound prospect lists.

Frederik JakobsenFounder @ Danish Lead Co

AI Ark is our trusted data layer: fresher, more accurate contacts and filtering we can scale. It powers outbound that's driven 10k+ commercial conversations and $30M+ revenue. We get sharper targeting and deliverability without higher client costs or the usual tradeoffs at all.

Aaron GusinovFounder @ LeadForce Solutions

My favorite AI Ark niche feature is bulk uploading website domains. It's perfect for working backwards from a set list of target companies, then using lookalike search to expand it. This small workflow shows how thoughtful the product is, world class compared to other databases that feel archaic.

Ali AsgharCo-Founder & CEO @ DFY Automation

What sets AI Ark apart is the sheer quality of their lead data; the email validation is so thorough that we've seen a significantly lower bounce rate compared to other databases. It's a tool we can actually rely on for high-stakes outreach without worrying about deliverability.

Andrew van RossenbergCo-founder @ Nebor

The TAM mapping is genuinely accurate, and it's much more user-friendly than the old-fashioned tools we all know the names of. What stood out to me is the technology filtering. For one campaign, we could filter out email security gateways to clean up our target list, which most platforms can't do. The lookalike function is built in too, so there's no need for a separate lookalike audience finding tool. It just works, and it's easy to use.

Javeria ShahCo-Founder & CTO @ DFY Automation

AI Ark's company-profile support has been a game-changer, eliminating domain mismatches and improving the accuracy of the people data we pull for outreach. Since switching, lead relevancy has jumped; industry filters are exceptionally precise, returning the exact companies we need at scale with minimal glitches.

Xavier CaffreyFounder-CEO @ OneAway

AI Ark helps us find 20–30% more leads than other databases, with genuinely up-to-date data refreshed every 30 days. The lookalike filter is best-in-class, and the 76 data points plus unique LinkedIn filters make list-building far more actionable. The team is consistently cooperative and responsive.

Dean FiaccoFounder @ Beanstalk

Since switching from Apollo to AI Ark, bounce rates are around 1% and 'wrong person' replies are rare. We export clean, verified data in under five minutes, and Saved Records prevents paying twice for the same contact. It's cut list-building costs and made our GTM engineers far more efficient.

Nayab OsafCo-Founder @ 7x GTM

We used Export Apollo and Apollo, but AI Ark's coverage is far better. My lead lists now contain 50%+ more data. What took 3–7 days of scraping now takes about 20 minutes. That coverage-plus-speed combo removed my client-delivery anxiety completely.

Aaron ShepherdFounder @ GrowthFlare

Most businesses are bolting AI onto broken tools. We built the growth operating system that actually makes it work, unified, compounding, and engineered to generate revenue. Our 4-layer architecture doesn't just generate leads, it gets smarter every week.

Mohan MuthooFounder @ Spring Drive

When I'm building targeted outbound lists for clients, AI Ark supports the research phase dramatically. Instead of stitching together data from inaccurate sources, I can pull enriched contact info and company signals in one place, which matters when you're running campaigns at the scale we do.

Can TimagurFounder @ Allbound OS

AI Ark has significantly improved how we build and export high-quality prospect lists at Allbound OS. With data refreshed every 30 days, we have more confidence in targeting accuracy and campaign performance. Pre-verified contacts and structured records help us segment smarter, reduce bounce rates, and move from raw data to actionable lists faster.

Taylor HarenFounder @ Sales Automation

AI Ark became our #1 source of positive replies. The intent and fit were so strong we'd need 10× more Apollo leads to match the same number of positive responses. For us, it's the clear highest-ROI data source and it scaled reliably week after week.

Ericson DalusongFounder & GTM @ Lead Assassin

AI Ark's data accuracy has made lead generation far more effective for us. The quality boost saves us a ton of time we used to spend fixing or rechecking records, and it's clearly improved outreach performance. We're reaching the right people faster, with cleaner data and better results.

Florent LekaGTM Engineer & Growth Lead @ AI bees

I've used AI Ark since the early days, and every update adds value. Its fresh, precise data improves targeting and performance. The API and keyword filtering pulling from descriptions, work history, publications, skills, and education make prospecting faster and more accurate. It also helped tailor country-specific messaging, lifting connection acceptance from 9% to 35% in a week.

Shubh SaxenaFounder @ TrueGTM

AI Ark's 30-day refresh keeps our signals accurate and cut campaign costs by 60%+ versus Apollo. With lookalikes, pre-verified emails, job-change signals, and role mapping built in, we no longer stitch tools together. Add a supportive team, and it's an easy recommendation for leaner outbound.

Kenny DamianHead of GTM @ Frontal

AI Ark does two things no other tool does. The MCP lets us describe an ICP in plain language and pull a targeted lead list directly inside our AI workflow, and the credit system means we're never double-charged when we re-pull the same data. Those two together make it the only data tool we actually trust to build on top of.

Sameer Malla ThakuriHead of GTME and Ops @ GrowthPal

The person-level keyword list search is incredible, and one of the biggest headaches in outbound – verifying emails – is no longer an issue. With a verifier integrated directly into the platform, the process is much smoother and faster. It saves time, reduces extra steps, and makes building clean, reliable prospect lists far easier.
