Biscred vs Tomba: You're Comparing Two Different Tools
CRE teams use specialized software - Yardi for property management, VTS for leasing, CoStar for market data. Biscred fits that stack as a CRE prospecting database. Tomba is a generic email finder. Comparing Biscred vs Tomba is a category error, and the only reason you'd search this is if you're in CRE wondering whether a cheap email tool can replace a purpose-built platform.
Let's sort that out.
30-Second Verdict
- Biscred if you prospect exclusively within commercial real estate and need CRE-specific filters like asset class, property count, and seniority.
- Tomba if you need a budget-friendly, general-purpose email finder and don't care about industry context.
- Skip both if you need verified B2B emails across industries with higher accuracy than Tomba and broader coverage than Biscred.

What Is Biscred?
Biscred is built on Bisnow's 14 years of CRE data. The database covers roughly 550,000 companies and 4.3 million CRE professionals, with about 10,000 contacts added and validated weekly. Its Criteria Search and Quick Search modes let you filter by asset class, property count, seniority, geography, and industry - the kind of CRE-specific intelligence no general email tool can replicate.
Beyond contact data, Biscred offers digital advertising activation, letting you target audiences using its CRE dataset. Integrations cover Salesforce, HubSpot, and Microsoft Dynamics, plus an open API. If a downloaded email bounces, Biscred replaces the contact or credits your account. Founded in 2020 in NYC with about 28 employees, it's a focused operation.
Use it if you sell exclusively into CRE - proptech, brokerage services, construction, lending - and need filters that general databases don't offer. For context, CRE lead marketplaces like BuyCRELeads charge roughly $1,250 per 10 leads, so a platform subscription pays for itself quickly.
Skip it if you prospect across multiple industries. Biscred has zero utility outside commercial real estate, and there's virtually no independent review footprint on G2 or Capterra to validate the experience. Pricing isn't public; expect mid-four-figures to low-five-figures per year depending on seats and download volume. If you're evaluating broader options, start with sales prospecting database comparisons.
Biscred locks you into CRE. Tomba gives you 80% accuracy and a bounced email every fifth send. Prospeo covers 300M+ profiles across every industry at 98% email accuracy - with 30+ filters, intent data, and a 7-day refresh cycle. All at $0.01 per email.
Stop choosing between niche coverage and bad data. Get both reach and accuracy.
What Is Tomba?
Tomba is a straightforward email finder with domain search, individual lookups, email verification, a Google Sheets add-on, data enrichment, and a Chrome extension. It carries a 4.7/5 on G2 across 25 reviews, though G2 notes the profile hasn't been active for over a year. That's not a great sign.
Tomba ran its own benchmark in February 2026 - 5,000 searches across 9 tools - and reported 80.3% accuracy. That's 4,015 valid emails out of 5,000, meaning 985 were invalid. Roughly 1 in 5 emails bounce, which is a real problem for domain reputation if you're running cold outbound at scale.
Pricing is transparent: free at 25 searches/month, Basic at $441/year for 2,500 searches, Growth at $801/year for 5,000, Pro at $1,791/year for 20,000, and Pro Plus at $4,041/year for 50,000 searches.
Use it if you need occasional email lookups on a tight budget and don't mind verifying results through a separate tool. If you want other options, see Hunter alternatives and other email search tools.
Skip it if you need integrations beyond the basics. G2 users flag the lack of professional-profile integration and UI inconsistencies between sections. A recurring complaint in third-party writeups: Tomba doesn't reliably find Gmail addresses even when they're present on a site, and it doesn't actually scrape emails from websites the way people expect.
Key Differences That Matter
Picture a proptech sales rep building a list of development firm executives in Texas with life sciences asset experience. Biscred handles that in one search. Tomba can't - it has zero industry context, no asset class filters, no property data. You'd need to already know the companies and contacts, then use Tomba just to find their emails.
Now picture a CRE lender who also prospects fintech CFOs for a new product line. Biscred covers the CRE side but is useless for fintech. Tomba works across both, but at 80.3% accuracy you're burning sender reputation on every fifth email. We've seen firsthand how the gap between 80% and 98% accuracy plays out - it's the difference between a healthy sender domain and one that's flagged within weeks. If you're trying to reduce bounces, use an email bounce rate playbook and prioritize email deliverability basics.
Neither tool solves both problems well.
Here's the thing: if you're in CRE and your average deal size justifies Biscred's price tag, use Biscred for CRE prospecting and pair it with a broader, more accurate tool for everything else. Don't try to make one tool do both jobs. If you're building a repeatable motion, align it with proven sales prospecting techniques.
If Neither Fits
Pricing runs about $0.01 per email with a free tier of 75 emails/month. No contracts, no demo calls, fully self-serve. Our team has tested this against both Biscred's CRE data and Tomba's general lookups, and the combination of cross-industry coverage with 5-step email verification is what makes the difference for teams that don't fit neatly into one category. If you need a broader stack, start with outbound lead generation tools and free lead generation tools.
If you prospect CRE and other verticals, you need a platform that doesn't force you to pick a lane. Prospeo's 30+ search filters cover industry, job title, company size, funding, and 15,000 intent topics - so you build targeted lists whether you're reaching development firm execs or fintech CFOs. No demo calls, no contracts.
One platform for every industry. 98% accuracy on every email.
FAQ
Is Biscred only for commercial real estate?
Yes, entirely. Every filter, data point, and classification is built around CRE workflows - asset class, property count, seniority within real estate firms. If you prospect outside CRE even partially, Biscred offers zero value for those contacts.
How accurate is Tomba's email data?
Tomba's own February 2026 benchmark reports 80.3% accuracy across 5,000 searches. That means roughly 1 in 5 emails bounce - a serious risk for domain reputation on cold outbound campaigns.
What's a good alternative if neither Biscred nor Tomba works?
Prospeo covers 300M+ profiles across all industries at 98% email accuracy and $0.01 per lead. It includes CRE-relevant filters like industry, job title, and company size, plus intent data across 15,000 topics - making it viable for CRE teams that also prospect outside real estate.
