Gazelle vs Prospeo: Different Tools, Different Jobs
Comparing Gazelle.ai to Prospeo is like comparing a telescope to a rifle - one finds the target, the other hits it.
They show up in different G2 categories: Prospeo sits in Lead Intelligence, while Lightcast Gazelle appears under Sales Intelligence and Account Intelligence. The confusion when weighing Gazelle vs Prospeo is understandable since both touch B2B company data, but they're built for different primary buyers. The overlap only kicks in when a team wants both company growth signals and verified contact data in the same workflow.

What Is Gazelle.ai?
Gazelle.ai is a Montreal-based platform founded in 2017. It raised $790K before being acquired by Lightcast and was named to Deloitte's Technology Fast 50 "Companies-to-Watch" in 2021.
Its core product is the G-Score: a proprietary AI model built by Ph.D. economists using 240+ data signals over a 10-year time series, validated against 6,000+ companies known to have expanded. The platform also offers industry heat maps at state and county levels, GIS-based company search down to zip code, and ecosystem mapping that charts buying and selling relationships across industries. On top of that, Gazelle runs a human-curated expansion projects operation where its in-house team interviews executives at 120,000+ companies per year to identify expansions planned 18-36 months out.
On its Capterra listing, Gazelle.ai is described as analyzing 98M company profiles and 15M verified contacts across 910 industry sectors.
On G2, Lightcast Gazelle carries a 4.7/5 rating from 61 reviews, with implementation time listed at about one month. Users praise the intuitive UI and customer service. The recurring complaint? Contact information accuracy can be inconsistent - reviewers note that because it scrapes online sites, some information needs validation by the user. Reddit threads asking about Gazelle experiences remain largely unanswered, which isn't shocking given how niche the audience is.
Gazelle's G-Score identifies companies likely to expand. But growth signals don't close deals - verified contacts do. Prospeo gives you 300M+ profiles with 98% email accuracy, 125M+ direct dials, and a 7-day refresh cycle, all starting at $0.01 per email.
Turn company growth signals into booked meetings with contacts that actually connect.
What Is Prospeo?
Prospeo is built for a different job entirely: turning target companies into reachable people.
The database spans 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobile numbers, all refreshed on a 7-day cycle. For context, the industry average refresh is closer to six weeks, which tells you how quickly most providers' data goes stale. Email accuracy runs at 98%, backed by a proprietary 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering. Mobile numbers carry a 30% pickup rate across all regions.
Real results back this up. Meritt tripled pipeline from $100K to $300K per week after switching, while cutting bounce rate from 35% down to under 4%. (If you’re trying to protect deliverability, start with email list hygiene and email deliverability best practices.)
The platform includes 30+ search filters with buyer intent on 15,000 Bombora topics, technographics, job changes, headcount growth, and funding signals. Pricing is self-serve and transparent: a free tier with 75 emails and 100 Chrome extension credits per month, paid usage at about $0.01 per email, no annual contracts.

The two rows that matter most are contact accuracy and pricing. In our experience testing both categories of tool, the contact accuracy gap is the deciding factor for sales teams. Gazelle's contact data gets flagged in G2 reviews as needing validation, while Prospeo's 98% email accuracy means you're not burning domain reputation on bad sends. And the pricing gap - CA$9,000/year versus a free starting tier - reflects the fact that these tools serve fundamentally different markets.
Here's the thing: if your deal sizes sit below $50K and you're running outbound, there's no reason to spend CA$9,000 on a growth-scoring tool when Prospeo's filters already surface expanding companies with verified contacts attached. (For more options in this category, compare B2B data providers.)
Which One Do You Need?
You're in economic development or investment attraction. Go with Gazelle. Its G-Score, expansion project tracking, and industry heat maps are purpose-built for this work, and nothing else on the market replicates that combination.
You're in sales, SDR work, or outbound. Prospeo. Verified emails, direct dials, intent data, self-serve pricing, native CRM integrations. This isn't a close call. Gazelle wasn't designed as a sales-first contact database, and the review feedback around contact validation reflects that.
The interesting case is when you need both company targeting and contact data. Use Gazelle to identify expanding companies in a target region with its G-Score, then feed those company names into Prospeo's enrichment API to get verified contacts back with 50+ data points each. The API's 92% match rate handles this cleanly, and enrichment returns contact data for 83% of leads. We've seen teams pair tools like this to great effect - the growth signal from one platform, the reachable contacts from another, stitched together with a simple API call or Zapier workflow. (If you’re formalizing this motion, see our guide to lead enrichment.)
Already using Gazelle to spot expanding companies? Feed those company names into Prospeo's enrichment API and get verified emails and direct dials back at a 92% match rate with 50+ data points per contact. No CA$9,000 commitment - just accurate contact data on demand.
Pair growth intelligence with contacts that hit 98% accuracy for $0.01 each.
