What CallApp does
CallApp Software Ltd., founded in 2012 and headquartered in Tel Aviv, Israel, operates a consumer mobile Caller ID and call-management platform built on a proprietary database of 8+ billion phone numbers across 200+ countries. The product flags spam, telemarketers, and robocalls in real time, enriches user contacts with photos and social profile data drawn from 60+ public and social sources, offers call recording with cloud backup, and extends identification to messaging surfaces including WhatsApp, Telegram, and SMS via the CallApp+ add-on. The application has been downloaded more than 100 million times on Google Play and is reported to have 25-40 million active users worldwide, with 2.5 million phone-number lookups processed daily.
The company runs a product-led, freemium distribution model through the Google Play and Apple App Store, monetizing via in-app advertising, a Premium subscription (also unlockable free through a 20-point Refer & Earn program), and a nascent B2B offering called CallApp for Business that delivers verified caller ID with branded call display and SMS on a subscription basis. Infrastructure is hosted on Amazon Web Services per the company's Data Protection Addendum, and no external APIs, SDKs, or developer programs are offered. Ownership is concentrated among founders (Amit On, Founder & CEO) and early-stage investors including Giza Venture Capital, Giza Polish Ventures, Susquehanna Growth Equity, and ATOORO FUND, with roughly $5 million in disclosed equity funding raised across 2012 and 2014.
Customer concentration is low by construction given a mass-market consumer base, but revenue visibility remains limited because no revenue, ARR, or downloads-per-period data has been disclosed. Recent strategic moves, including the 2025 launch of CallApp for Business and the extension of identification to WhatsApp, indicate a managed, incremental expansion rather than an aggressive scaling posture, and the company's 13-year operating history suggests a stable, middle-stage private entity rather than an early-stage high-growth venture.

CallApp competitors and assessment
Company assessmentDirect peers
- RoboKiller: RoboKiller is a consumer spam call blocking and caller ID app with an audio fingerprinting-based call-screening technology. Overlaps with CallApp on spam blocking, call identification, and premium subscription monetization.
- Should I Answer?: Should I Answer? is a community-rated call blocker and caller ID app widely used in Europe with a global database of unwanted callers. Competes in the same category with comparable freemium features.
- Nomorobo: Nomorobo is a popular spam call blocker with both consumer (mobile app) and carrier-grade offerings. Directly comparable in feature scope to CallApp's Spam & Block feature set, including real-time spam detection on incoming calls.
- Truecaller: Truecaller is the global leader in consumer caller ID and spam blocking, with ~400M MAUs. CallApp explicitly claims to be the largest caller ID app in the US but competes against Truecaller's deeper data network and global footprint in the same core product category.
- Hiya: Hiya provides both a consumer caller ID/spam blocking app and the Hiya Connect B2B verified caller ID service (a direct analogue to CallApp for Business). Comparable product mix, business model, and target markets.
- Whoscall: Whoscall (by Gogolook) is a Taiwan-headquartered caller ID and spam blocking app with ~100M downloads — particularly strong in Asia. A direct regional/global peer competing on database-driven caller identification.
- Mr. Number: Mr. Number is a well-known call-blocking and caller lookup app for Android and iOS, with similar identify-spam, block-list, and reverse number-lookup features to CallApp. It also offers enterprise-grade call-blocking APIs for businesses.
- TrapCall: TrapCall is a caller ID and call-unmasking service for unknown numbers, allowing users to identify and record calls from blocked numbers. Targets the same consumer pain point and shares the freemium/premium model with CallApp.
Others
- Cellebrite: Cellebrite, also Israeli-based, works in mobile data and communication intelligence (lawful intercept, device forensics) and uses extensive phone number databases. Adjacent rather than directly competitive, but indicative of Tel Aviv's mobile-data ecosystem.
Emerging players
- Truecaller Enterprise (Truecaller for Business): Truecaller's B2B verified-caller-ID offering is the direct analogue to CallApp for Business. Same target buyers (enterprises needing branded verified calls), same mechanism (verified call display) — making it the key benchmark for CallApp's B2B expansion ambitions.
