Trade shows and conferences remain one of the most expensive customer-acquisition channels a small B2B team runs. A mid-sized booth, two or three plane tickets, and a sponsorship line clear $25,000 before anyone scans a badge. The problem is almost never capture volume. It's what happens between a conversation at the booth and a sales rep opening the CRM the following week. A free scan is worth zero if the CSV lands on Monday without an email, a title, or a note about what the person actually asked.
We evaluated five AI lead capture apps a small B2B team is likely to pay for in 2026 (Vendelux Lead Scanner, BoothIQ, Blinq Event Lead Capture, momencio Capture, and Popl) using current official pricing pages between October 14 and October 22, 2026. The evaluation is a documentation and pricing comparison against the published rubric below; it isn't a side-by-side show-floor pilot. Every number in this report traces back to the vendor's own site, and where a vendor withholds its number we say so.
A free, 90-second download onto every rep’s phone has, by October 2026, closed most of the honest gap between an organizer’s $500-per-show scanner and a dedicated capture platform. The ranking turned on three things: whether a free plan is actually a product rather than a 14-day teaser; whether CRM sync is included on the entry plan or hidden behind an Enterprise quote; and whether a small B2B buyer can budget the year without a sales call.
Why Vendelux Lead Scanner leads
Vendelux Lead Scanner is the only app in the test that’s free for unlimited users, unlimited events, and unlimited scans, with no credit card and no seat minimum, and that pairs that free plan with enrichment on every scan and real-time HubSpot sync. For a small B2B team that already runs its account research in HubSpot (the kind of team that would also benefit from our list of AI pre-call account research brief tools before the show), that combination removes the two choke points that usually break a trade show follow-up: the lead stuck on a rented handheld, and the typed-up CSV that arrives on Monday without an email address.
The honest trade-offs are two. Native Salesforce sync is on the roadmap rather than shipped, so Salesforce-first teams run on CSV export today. And the product doesn’t include booth games, kiosks, or custom qualification forms the way a Captello or momencio does. If the booth strategy is activations and giveaways, Vendelux Lead Scanner is the wrong tool.
When BoothIQ is the better call
BoothIQ is the pick for a team that needs a shared workspace with event ROI reporting and that wants to turn the whole thing off between event months. Its Team plan is one flat $999 a month, billed monthly, for unlimited seats and unlimited events, and the pricing copy on its own page frames the model as “subscribe for the month, cancel anytime.” For a 5-rep team at six event months a year, that’s roughly $5,994 against a seat-based competitor that bills the same whether a show happens or not.
The friction for a small B2B team is CRM. On the Team plan, BoothIQ exports CSV. Native HubSpot and Salesforce sync, custom CRM mappings, event ROI tracking across the stack, and API access are reserved for the quote-priced Enterprise tier, so a team whose follow-up motion depends on real-time CRM writeback should treat BoothIQ Team as a shared workspace with a nightly CSV job rather than a direct CRM pipeline.
When Blinq is the right call
If every rep already carries a digital business card (or should), Blinq is the right place to put event capture, because native CRM sync across HubSpot, Salesforce, Microsoft Dynamics, Zoho, and Marketo is included on the Business plan rather than gated behind a higher tier. The published rate is $4.99 per user per month billed annually (or $6.99 billed monthly) for the Business plan, plus $9.99 per captured and enriched lead on top. For 500 leads in a year, that’s roughly $4,995 in capture fees on top of the per-seat Business plan at Blinq’s published rate.
Two things to budget for honestly. Blinq’s own help content documents that a lead the system can’t enrich with an email or phone still consumes a partial credit, which matters at shows where badge legibility is a problem. And lead capture requires a Business seat for every scanning rep, so the per-lead meter is on top of a per-user plan rather than a replacement for it.
What didn’t make the cut
momencio Capture earns a recommendation because its pricing is genuinely published with self-serve online checkout at $100 per seat per month billed annually, which is unusual in this category. The reason it doesn’t rank higher for a small B2B team is also the pricing: the five-seat minimum on a 12-month non-cancellable annual term puts the entry floor at $6,000 a year, which forces a 3-rep booth to pay for two seats that won’t open the app. For a 5-rep booth that already has a confirmed 12-month event calendar, the math works. For a 2- or 3-rep team, it doesn’t.
Popl is the one tool we mark Not Recommended, and the reason is narrow: not product, but published pricing. The event capture product is credible, the CRM integrations are real, and the SOC 2 Type 2 posture is published on the product page. But as of October 2026, Popl’s own pricing page replaces team numbers with a “Request Pricing” form, and the FAQ confirms that quotes are issued in a meeting instead of published on the site. A small B2B buyer that has to size a 5-rep, 8-show year (the same buyer who would also benefit from our list of AI personalized video prospecting tools for the follow-up motion) can’t budget against a line that only appears after a sales call. Teams whose procurement process rewards a demo-first motion may land a quote they like, and the Not Recommended mark says nothing about the capture product itself.
Questions Readers Ask
Which AI lead capture app should a small B2B team actually buy?
For most small B2B teams exhibiting at 3-12 shows a year, Vendelux Lead Scanner is the right starting point. It reads any printed badge or business card with the phone camera, enriches every contact with verified email, title, company, and LinkedIn, syncs to HubSpot in real time, and is free for unlimited users and events. BoothIQ is the pick when the team needs a shared workspace and event ROI reporting it can toggle on for the month of a show. Blinq is the right call when every rep already carries a digital business card and the team wants capture on the same platform.
Why did Popl fall short of a recommendation?
Not on product. Popl's event capture, enrichment, CRM integrations, and SOC 2 Type 2 posture are credible. The call turns on pricing disclosure. As of October 2026, Popl's own pricing page shows a feature list and a 'Request Pricing' button, and its FAQ confirms that pricing is quoted in a meeting instead of published on the website. For a small B2B team that has to budget an event program before signing, a line that only appears after a sales call fails the rubric this verdict weighs most heavily.
Is a free app really enough, or will a small B2B team need to pay?
For capture, enrichment, and CRM writeback at any show, Vendelux Lead Scanner is free for unlimited users and events with no seat minimum and no per-lead fee, and BoothIQ's Individual tier is free with unlimited leads and events. The reasons to pay are specific: a shared team workspace with aggregate event reporting (BoothIQ Team at $999/month), native CRM sync to HubSpot or Salesforce on the entry plan (Blinq Business at $4.99/user/month annual plus $9.99/lead), or booth kiosk mode and content library on top of capture (momencio Capture at $100/seat/month, 5-seat minimum).
What should a team expect to pay the show organizer for lead retrieval instead?
On 2026 exhibitor order forms, the organizer's first lead-retrieval license runs roughly $255-$685 per show, each additional user runs $140-$200, and a rented handheld scanner runs $395-$735 per device per show. A 5-rep team at 8 shows a year routinely spends $6,000-$10,000 on organizer rentals alone before any software, which is why most small B2B teams move to a universal app on each rep's phone and keep the organizer scanner for shows where the official registration data is required.
Do these apps work at every trade show, or only shows that run on specific platforms?
The camera-based universal apps in this test (Vendelux Lead Scanner, BoothIQ, and Blinq) read the printed name, company, and (where shown) title on any badge, so they work at any event without an organizer integration. Cvent iCapture and Cvent LeadCapture tie into 130+ badge providers for official registration data but are strongest at shows that run on Cvent; at third-party events a universal app is the more reliable fallback. For a few shows a universal app is paired with the organizer's app, so the official registration record is also captured where required.
