## Kampfire

Kampfire starts from a simple insight: the event is over, and the follow-up funnel is broken. Attendees are six inboxes deep by Monday, generic 'great meeting you' emails blend together, and event ROI stays a guess. Instead of another reminder cadence, Kampfire gives attendees a reason to come back — a personal souvenir from the event. The platform gathers photos, videos, recaps and sponsor assets, then builds a fully branded experience around each attendee's own moments in the event.

The mechanic is AI-powered face matching: attendees upload a selfie and instantly find the photos they appear in. From there they enter a personalized hub with sponsor offers, surveys, white papers, session summaries and conversion CTAs, and every interaction is tracked. Kampfire reports 40-50% average attendee re-engagement, roughly 2x lift in conversion versus standard follow-up, and 2.5x post-event pipeline value, with signals flowing into Slack, Salesforce, HubSpot and similar tools.

Kampfire is privacy-first by design, with consent-managed sharing, retention controls, guest opt-out, attendee consent forms, MFA on every plan and GDPR/CCPA/BIPA guidance at higher tiers. It plugs into the tools event teams already use, including Cvent, Swoogo, Salesforce and HubSpot, and is sold as a subscription or as one-time credit packs for single events. It is built by Obrecsys and used by event teams at organizations such as Accenture, IHG Hotels & Resorts and BNP Paribas.

**Pricing & Plans:** Paid subscription plans plus one-time credit packs. Recurring plans start at US$249/month (Basic, ~100 engaged attendees and 500 photos) and run through Pro at US$449/month and Premium at US$799/month, with annual billing saving about 17%. One-off events can use credit packs from US$550, and Enterprise pricing is quoted on request. Kampfire bills only for engaged attendees, not for total headcount, and every subscription includes a 30-day money-back guarantee.

- **AI selfie photo matching:** Attendees upload a selfie and instantly find every official event photo they appear in — the hook that pulls them into the experience.
- **Personalized attendee hubs:** Each attendee gets a branded page combining their own moments with sponsor offers, surveys, white papers, session recaps and CTAs.
- **Attribution-grade intent signals:** Views, shares, clicks, survey responses, registrations and conversions are timestamped and pushed to Slack, CRM and event platforms.
- **Engagement analytics:** Event-level and attendee-level analytics with CSV export, plus AI-powered best photo selection per attendee on higher tiers.
- **Integrations and privacy controls:** Connects to Cvent, Swoogo, Salesforce, HubSpot and more, with consent management, opt-out, retention controls and GDPR/CCPA/BIPA guidance.

**Strengths:** Only charges for engaged attendees, not for full registered headcount; Personalized photo hubs give attendees a genuine reason to return and share; Intent signals land directly in Slack and CRM with timestamped attribution; Privacy-first design with consent management, opt-out and retention controls

**Limitations:** Subscription pricing is aimed at professional event teams and may be steep for small one-off events; Some of the strongest features — custom templates, white-label domains, CRM push — start at higher tiers; Photo matching still requires good official photography as the raw material

## Lenso.ai

Lenso.ai applies content-based image retrieval (CBIR) and dedicated neural models to help you trace any picture back to its sources online. Instead of a single generic search, it offers purpose-built categories: People (facial recognition search), Places, Duplicates, and Similar/Related images. Each category uses models trained for that task, which produces more precise results than a one-size-fits-all image lookup.

The platform is popular with photographers, artists, and content creators who want to monitor where their work appears, verify copyright ownership, or find the original source of an image. Advanced Filters let you narrow results by page language, domain, date range, image size, and keywords in the page title, while Research Mode expands results for People and Duplicates up to roughly 10,000 matches. You can also save results into collections, set alerts when new matches appear, and share any search via link.

For businesses and developers, Lenso.ai sells a Developer subscription that unlocks the Image Search and Face Search API with up to 5,000 calls per month, plus usage tracking in your account panel. The service is free to start, with paid tiers unlocking deeper search, advanced filters, and higher API volume.

**Pricing & Plans:** Freemium. Core reverse image and face search can be tried for free; paid plans unlock Research Mode, Advanced Filters, more unlocked results, and API access (Developer plan up to 5,000 calls/month).

- **Facial recognition search:** Find where photos of a given face appear online by matching facial details with high precision.
- **Duplicate and copyright tracing:** Locate exact copies of an image and identify the original source to protect your copyright or credit correctly.
- **Multi-category image search:** Run separate searches for people, places, duplicates, similar, and related images, each backed by task-specific models.
- **Advanced filters and Research Mode:** Filter by language, domain, date, size, and title keywords, and expand results to roughly 10,000 matches per search.
- **Image Search and Face Search API:** Add Lenso's search engines to your own apps with a Developer subscription supporting up to 5,000 calls per month.

**Strengths:** Purpose-built search categories deliver more precise results than generic image search; Strong duplicate and copyright tracing with original-source detection; Developer API with visible monthly call allowance; Free tier lets you test face and image search before paying

**Limitations:** Full result sets and deeper search require a paid plan; Facial recognition search raises privacy considerations that vary by jurisdiction; API volume is capped by the Developer plan tier
