Gigasheet vs Seamless.AI: Why This Comparison Doesn't Work
Someone on your ops team mentioned Gigasheet because they use it for analytics. Your SDR manager wants a contact tool. Now you're trying to figure out if these two products overlap. They don't. Not even a little.
Gigasheet is healthcare price transparency analytics at massive scale - think billions of rows of payer-negotiated rates. Seamless.AI is a B2B contact finder for outbound teams with credits, exports, and CRM pushes. The only reason this comparison exists is because both tools touch "data," and procurement loves lumping data tools into the same evaluation.
Here's the thing: the right question isn't "which is better?" It's "which job are we actually trying to get done?"
What Is Gigasheet?
Gigasheet is purpose-built for healthcare price transparency and market intelligence. It lets teams explore payer-negotiated rates, benchmark pricing, and trace insights back to original machine-readable files. It handles billions of rows without forcing anyone into SQL, which is genuinely impressive for the healthcare ops crowd.
Use this if you're in healthcare - providers, payers, self-insured employers, MedTech market access - and need to interrogate huge price transparency datasets fast, with traceability back to source files. It's SOC 2 Type 2 certified and integrates with Snowflake and BigQuery.
Skip this if you're trying to source B2B contacts for outbound. This isn't a sales intelligence database. Not even close.
Gigasheet Pricing
More transparent than most healthcare tooling, with multiple packages depending on what you're analyzing:
- Premium: $25/month billed yearly ($295/year) or $95/month billed monthly
- Premium Individual: $75/user/month billed annually, $95/month if billed monthly
- MRF Explorer: $295/user/month billed annually (paid as $3,540/year), with enterprise packaging that can push to $5,000/year per user depending on the deal
Rated 4.9/5 from 23 reviews on G2. Small sample, but the scores are strong.
What Is Seamless.AI?
Seamless.AI is a B2B contact finder: search for people and companies, export emails and phone numbers, and push lists into your outbound motion. It carries a 4.4/5 rating from 5,319 reviews on G2, and its database covers 1.7B+ contacts.
Reviewers consistently praise ease of use (1,181 mentions) and fast contact access (1,184 mentions). But the negatives are just as consistent: inaccurate data (410 mentions), outdated contacts (295), and expensive (222). Third-party reviews also summarize user complaints of 20-30% email bounce rates, which eats into any time savings fast.
Use this if you want a rep-friendly interface and you're okay with credit economics. It integrates with Salesforce, HubSpot, and Dynamics, so CRM pushes are straightforward.
Skip this if you need predictable cost per usable contact and care about data freshness. We've seen too many teams get burned by the gap between "contacts exported" and "contacts that actually work."
What You'll Actually Pay for Seamless.AI
Seamless.AI requires a sales call for anything beyond Free. The structure is credits + seats + add-ons:
- Free: $0 / 50 credits
- Basic: ~$147/mo (annual)
- Pro: $79-$299/user/mo
- Enterprise: $149+/user/mo, 5-user minimum (~$745/mo floor)
Credit burn is the real story. One Reddit breakdown shows a $79/mo plan turning into $177/mo after two credit top-ups. Add-ons commonly push total cost 40-60% above the base license. That works out to roughly $0.12-$0.20 per usable contact after bounces and waste.
On the trust front: Seamless.AI has 75 BBB complaints in 3 years (33 in the last 12 months), mostly renewal and cancellation disputes. Contracts often require 30-60 days written cancellation notice. That's a frustrating pattern we keep seeing across credit-based sales tools - the pricing looks reasonable until you're locked in and the overages start stacking.
Seamless.AI's UI is genuinely good for reps who just want to pull a list and go. But "easy to use" doesn't matter much when a quarter of your emails bounce and your finance team can't reconcile the invoice. If you're trying to reduce bounces, start with email verification before you scale volume.
Seamless.AI users report 20-30% bounce rates. Prospeo's 5-step verification delivers 98% email accuracy with a 7-day data refresh - no stale contacts, no credit overages, no sales calls to get pricing.
Replace credit burn with contacts that actually connect.

Which One Do You Actually Need?
You need to analyze billions of healthcare pricing rows - payer-negotiated rates, MRFs, traceability back to source files - pick Gigasheet. It's built for that scale and compliance posture, and nothing in the sales intelligence category comes close to replacing it for that job.
You need B2B contact data for outbound sales - it's not Gigasheet. Seamless.AI can work, but you're buying into credit economics, sales-call pricing, and accuracy variance. That combo creates what I'd call "quiet waste": reps export a lot, ops cleans a lot, and nobody can explain the real cost per meeting booked.
For teams that want contact data without the contract games, let's talk about what actually matters. Prospeo gives you 300M+ professional profiles with 98% email accuracy, a 7-day refresh cycle, and self-serve pricing at roughly $0.01/email with no annual commitment. Our customers typically see bounce rates drop below 4% after switching from credit-based tools. The free tier includes 75 emails/month, so you can validate the data before spending anything. If you're building lists at scale, pair it with a clean lead generation workflow and consistent lead enrichment.
At $0.12-$0.20 per usable Seamless.AI contact after bounces, you're paying 12-20x what Prospeo charges for verified emails. 300M+ profiles, self-serve pricing, bounce rates under 4%. No annual lock-in.

FAQ
Are Gigasheet and Seamless.AI competitors?
No. Gigasheet is healthcare price transparency analytics for massive machine-readable datasets. Seamless.AI is B2B sales intelligence for finding contact data. They serve different categories, different buyers, and different workflows entirely.
Is Seamless.AI pricing transparent?
Not really. Beyond the Free tier, pricing requires a sales call and varies by seats, credits, and add-ons. Real costs commonly land 40-60% higher than the base license once add-ons are included, and credit top-ups push it further. The BBB complaint history around billing and cancellations tells you what you need to know.
What's a good alternative for B2B contact data?
Prospeo offers 300M+ profiles with 98% email accuracy, transparent pricing from ~$0.01/email, no contracts, and a free tier of 75 emails/month. Data refreshes every 7 days - roughly six times faster than the industry average.
