Overview
Tenjin gave mobile app marketers one system for attribution, ad spend, revenue, retention and raw data. Founded by former Tapjoy contributors Christopher Farm and Amir Manji, it joined YC Summer 2014, launched in 2015 and raised $2.5 million in 2016.[1]
Its insight was that attribution alone did not answer the business question. Marketers needed to join acquisition cost with purchases, subscriptions and ad revenue, then inspect the raw records. Privacy changes later made that job harder and increased the value of explicit uncertainty. YC now labels Tenjin acquired, but the company remains active and no source names a buyer, date or terms.[2]
Founding Story
Christopher Farm and Amir Manji had worked on the growth of Tapjoy, an early mobile advertising and monetization platform. They saw app marketers assemble attribution, analytics, ad-network cost and internal warehouse data from separate vendors.[1]
Farm described the problem from direct experience: "We experienced first-hand how fragmented and messy the mobile marketing industry is, and how much app marketers struggle to access and organize the raw data." The company formed in 2014 and joined YC that summer. It launched publicly in August 2015.
The product thesis joined two ideas. First, attribution should connect an install to the campaign or network that drove it. Second, the customer should be able to query the underlying data rather than accept a fixed dashboard. Farm said: "Our goal is to help developers connect the digital dots in a user's lifecycle using a single service and platform."[1]
NetEase Capital led a $2.5 million round in June 2016, with earlier backing from YC, Lightbank and angel investors. Tenjin named Yelp, NaturalMotion, Playdots, N3twork and KLab among customers.[1]
Timeline
- 2014: Farm and Manji founded Tenjin and joined YC Summer 2014.[2]
- August 2015: Tenjin launched its mobile-marketing infrastructure.[1]
- June 2016: NetEase Capital led a $2.5 million round.[1]
- 2016: Tenjin reported more than 300 million monthly events and 70 advertising or media integrations.[1]
- 2021 onward: Apple's iOS privacy changes reduced user-level data, and Tenjin emphasized aggregated revenue attribution.[3]
- 2026: YC displayed an acquired status without transaction details.[2]
What They Built
Tenjin's attribution layer connected ad clicks and impressions to app installs. For ordinary networks, a tracking link carried campaign and click identifiers; the Tenjin SDK reported the install; the service matched the records and sent callbacks. Self-attributing networks such as Apple, Meta, Google and Snap returned their own attribution data.[4]
The dashboard combined acquisition cost with post-install behavior: purchases, subscriptions, ad revenue, retention and return on ad spend. That mattered for free-to-play apps, where a user could create value through advertising without making an in-app purchase.
DataVault made the infrastructure accessible. Customers could query joined tables for events, campaigns, networks, apps, country-level spend and daily ad revenue instead of exporting each system by hand.[5]
Privacy changes altered what could be known. With less granular iOS data after version 14.5, Tenjin used aggregated session-based revenue attribution and described it as a more conservative view that included users who opted out of advertising identifiers.[3] The current platform continues to combine deterministic signals, network reports and modeled aggregates.
Market Position
Target Customers
Tenjin focused on mobile app developers, marketers and publishers, especially teams buying users across several ad networks but lacking a dedicated data engineering group.
Market Size
No observed source gives a defensible serviceable-market estimate. Tenjin says it has supported more than 10,000 companies since 2014, but that figure is not independently audited.[6]
Competition
AppsFlyer, Adjust, Branch and Kochava compete as mobile measurement partners. Large app publishers can also build internal pipelines. Tenjin positioned itself around accessible pricing, ad-revenue attribution and direct warehouse access.
The category has a structural trust problem. Ad networks report their own performance, platform privacy rules restrict independent measurement, and attribution methods disagree. A measurement partner must explain those boundaries without making its product appear weak.
Business Model
Tenjin sells recurring measurement software with a free entry plan and paid usage tiers. Its documentation describes flat plans that include attribution, ad-revenue callbacks, DataVault and exports, rather than charging separately for each module.[7]
The business benefits from customer switching cost: replacing an attribution SDK and historical data pipeline is disruptive. It also bears integration cost as every major network and platform changes interfaces. Current revenue, retention and gross margin are not public.
Traction
By June 2016, Tenjin said it had processed more than $100 million in ad spend, nearly $25 million in ad revenue and 300 million events per month.[1] The current company says more than 10,000 businesses have used its tools since 2014.[6]
Post-Mortem
Measurement lost determinism
Tenjin's early promise was to connect cost and user value in one queryable system. Apple's privacy changes removed much of the device-level signal used for that connection. The company responded with SKAdNetwork support and aggregated session-based ad-revenue attribution.[3]
That remedy preserved usefulness but changed the product's epistemic contract. A modeled cohort estimate and a device-level match answer different questions. The most durable measurement vendor is the one that labels the distinction, reconciles sources and shows what remains unknown.
Data control created responsibility
Direct warehouse access differentiated Tenjin from fixed dashboards. It also concentrated device, campaign and revenue data. Tenjin's privacy policy places consent obligations on app developers and lists device and attribution fields that customers may send.[8] Security, deletion and data minimization therefore sit inside the value proposition.
The acquired outcome is unverified
YC labels Tenjin acquired while listing active founders and a live product.[2] Tenjin's site markets current features and employment under the same name.[6] No observed announcement supplies a buyer, date, terms or integration. The company may have completed an undisclosed transaction, or the directory label may be incomplete; the record cannot distinguish them.
Key Lessons
- Tenjin joined cost to value. Attribution became more useful when the same system connected ad spend with purchases, subscriptions and ad revenue.
- Raw access was a product feature. DataVault let sophisticated customers build their own models without maintaining the full ingestion layer.
- Privacy changed certainty, not demand. Teams still needed campaign decisions after iOS 14.5, but the product had to separate observed, network-reported and modeled results.
- Trust grows from visible limits. A measurement vendor earns credibility by showing disagreement and uncertainty instead of forcing one exact answer.
