# AdStack > AdStack is ad serving and monetisation infrastructure for mobile apps, connected TV (CTV), OTT and digital video. It handles request routing, ad delivery, decisioning controls and event tracking. AdStack is a product of Algosoft Apps Technologies (P) Ltd., based in Noida, India. Last updated: 4 October 2026. ## What AdStack is AdStack is a delivery layer that sits beside a publisher's or platform's existing player and ad server. It is built for publishers, OTT platforms, app developers, CTV operators, ad networks, advertisers and ad-tech teams. It does not replace an ad server or an SSP; it takes on specific jobs such as hosting, allocation, geography checks and independent tracking. ## Who it is for - Publishers and OTT platforms: delivery, hosting and tracking beside an existing player and ad server. - Ad networks: controlled allocation between sources and an independent record to reconcile against. - Advertisers: campaigns on chosen screens and regions, with signed delivery and event data. - App developers, CTV operators and ad-tech teams: individual components or the whole delivery layer. ## Core capabilities - Mobile, CTV, OTT and video ad-serving workflows. - First-party hosted ad content delivered through CDN infrastructure worldwide. - Support for third-party VAST wrappers and external ad-serving workflows. - MaxMind IP intelligence for IP detection, geographic and policy decision support, and delivery controls. - Weighted delivery and allocation calculations. Each eligible campaign's share equals its weight divided by the total of all eligible weights. - HMAC-based event signing and tracking integrity checks. - Multiple independent trackers for delivery, impressions, events and quality monitoring. - Support for third-party trackers (impression and click pixels, VAST tracking URLs, viewability and verification tags, attribution postbacks, client endpoints) fired alongside AdStack's own signed trackers. - Fraud-signal monitoring and decisioning support. Thresholds and responses are agreed per integration. - Reporting on impression, quartile and other event tracking: reports by geo, app and bundle ID, site and domain, placement, device and OS, campaign and creative, quartile and completion funnels, reconciliation against third-party trackers, and quality and fraud-signal views. Custom reports and exports are agreed during integration. - Flexible integrations for publishers, app developers, CTV operators and ad-tech teams. ## Regions served AdStack serves all regions, all countries and all cities, including India, APAC, East Asia, Oceania, the Middle East, North Africa, South Africa, Europe, North America and South America. Regional rules (allow, restrict or weight by region) use IP intelligence. ## How instant ad serving works The player requests an ad. AdStack decides and returns a VAST response pointing at a CDN URL for the creative. The viewer is routed to a nearby point of presence (PoP): a smaller edge PoP close to the viewer or a major PoP in the nearest hub. A cache hit streams at once. On a miss the PoP fetches from a larger upstream PoP, and only then from the origin; each PoP keeps a copy so later viewers nearby get a hit. Video is delivered as progressive files or short streaming segments so playback starts quickly, and quartile tracking (start, 25%, midpoint, 75%, complete) fires a separate signed tracker for each event. ## Supported ad-tech workflows AdStack supports workflows involving Google Ad Manager (GAM), SpringServe, Magnite, Aniview and FreeWheel (Comcast), plus PubMatic, Index Exchange, OpenX, Equativ, TripleLift, Publica, Prebid, Google AdMob, AppLovin MAX and Unity LevelPlay workflows, third-party VAST wrappers, CDN-hosted creative and independent tracking. Custom and bespoke integrations are supported too. Support is subject to client-side setup and each platform's own requirements. AdStack is designed for compatibility with common ad-tech integrations and wrappers, and is built to support CTV and OTT environments, including device and publisher workflows. ### Tracker, verification, attribution and measurement services AdStack supports third-party tracker, verification, attribution and measurement workflows through pixels, VAST tracking URLs, tags and postbacks, fired alongside its own signed trackers. Examples: Integral Ad Science, DoubleVerify, Comscore, Nielsen, Pixalate, HUMAN Security, Protected Media, Zefr and Adloox (verification and viewability); AppsFlyer, Adjust, Branch, Kochava, Singular and Airbridge (mobile attribution); Google Campaign Manager 360, Innovid and Flashtalking (ad-server and creative trackers); iSpot.tv, Samba TV and VideoAmp (CTV measurement). Services not listed are supported as custom integrations. ### CDN and hosting environments Hosted creative is addressed by plain URLs, so delivery can be fronted by the CDN or hosting provider a team already runs, such as Cloudflare, Akamai, Fastly, Bunny, Amazon Web Services, OVHcloud, Linode or Hetzner. ## Support, in plain terms AdStack supports integrations and workflows. "Supports" and "is compatible with" describe how a workflow can be implemented, subject to client-side setup and each platform's requirements. Platform and provider names are trademarks of their respective owners. ## Typical use cases - A CTV or OTT publisher wants first-party hosted creative, weighted allocation between campaigns and signed tracking beside its existing ad server. - A mobile app developer wants to change geography rules or campaign weights server-side without shipping a new app build. - A video publisher wants an independent tracker kept alongside a third-party VAST wrapper chain. - An ad network wants a controlled split between demand sources and a second record to reconcile against. - An advertiser wants a campaign placed on chosen screens and regions, with signed delivery and event data to inspect afterwards. ## Limitations - IP geolocation is a strong signal, not a certainty; accuracy varies by region and connection type. - Platform accounts, tags, line items and policies belong to the client; AdStack works with that set-up. - Fraud-signal monitoring reduces risk but cannot guarantee zero invalid traffic. ## Contact - Company: Algosoft Apps Technologies (P) Ltd. - Email: info@algosoft.co - Phone / WhatsApp: +91 70119 69292 - WhatsApp: https://wa.me/917011969292?text=Hello%20Algosoft%2C%20I%20would%20like%20to%20discuss%20AdStack.%20Could%20we%20talk%20about%20how%20it%20fits%20our%20ad%20setup%3F - Address: C-25, MiQB Building, Sector 58, Noida, Uttar Pradesh 201309, India ## Pages - [Home](https://adstack.in/): Overview of the delivery layer, supported environments, integrations, regions and FAQ. - [Solutions](https://adstack.in/solutions): Mobile, CTV, OTT and digital video delivery; first-party CDN hosting; instant ad serving from smaller and major PoPs; video streaming; decisioning. - [Instant ad serving and PoPs](https://adstack.in/solutions#instant) - [CDN delivery](https://adstack.in/solutions#cdn) - [Decisioning](https://adstack.in/solutions#decisioning) - [Integrations](https://adstack.in/integrations): Google Ad Manager, SpringServe, Magnite, Aniview, FreeWheel and more; VAST wrappers; third-party trackers; verification, attribution and measurement services; custom integrations. - [VAST wrappers](https://adstack.in/integrations#vast) - [Tracker, verification and measurement services](https://adstack.in/integrations#verification) - [Platform](https://adstack.in/platform): Weighted delivery, HMAC-signed tracking, MaxMind IP intelligence, fraud signals, independent trackers, quartile tracking and reporting. - [Quartile tracking](https://adstack.in/platform#quartiles) - [Reporting](https://adstack.in/platform#reporting) - [Contact](https://adstack.in/contact): Contact form and company details. - [Sitemap](https://adstack.in/sitemap.xml)
