Emerge Tools

Overview

Emerge Tools built a mobile-development suite for work that app teams usually scattered across CI scripts, device labs, and manual review: app-size analysis, dead-code removal, build distribution, launch-time diagnosis, performance testing, and visual regression testing. Founded in late 2020 by Josh Cohenzadeh and Noah Martin, the W21 company reached demanding customers including DoorDash, Square, Airbnb, Duolingo, Stripe, Spotify, Tinder, and OpenAI.^[1][2]

Its May 2025 sale to Sentry was a product validation, not a failure. It also revealed the constraint on a nine-person specialist vendor: six technically credible tools still had to clear enterprise security reviews, integrate with two mobile ecosystems, and earn a budget beside incumbent observability platforms. Sentry could place the best of that suite inside a product already used by 4 million developers and 130,000 organizations.^[3]

Founding Story

Cohenzadeh and Martin were not a newly assembled founding pair. They had built apps together since high school in 2011, first working from a parent's living room and later a garage.^[2] Their pre-Emerge projects included QuickRes, a screenshot manager, a Tesla menu-bar widget, and an experiment that A/B-tested Tinder profile photos. That history matters because Emerge was born from repeated exposure to mobile tooling rather than a top-down market thesis.^[4]

The initial wedge was app size. Mobile teams could see that a release had become larger, but finding which binary symbols or assets caused the increase required specialist work. The commercial cost was legible: TechCrunch reported an Uber estimate that App Store size limits could cost an app up to 10% of installs. Emerge began with iOS and added Android in October 2021.^[4]

In November 2021 the company announced $1.7 million in funding from Haystack, Matrix Partners, Y Combinator, Liquid 2, Upside Partnership, and angels.^[3][4] The founders told TechCrunch that enterprise customers brought security and legal reviews, while a self-service motion was still planned. That tension, deep technical value paired with a high-friction sale, shaped the company more than any lack of product demand.

The founders' retrospective was unusually direct. Their acquisition post opened, “We have big news: Emerge Tools is joining Sentry,” then documented that six products had processed millions of builds by early 2025.^[2] Martin framed the next phase around reach: “We look forward to further empowering the mobile community at an even larger scale.”^[3]

What They Built

Emerge grew from one diagnostic into six products. Size Analysis compared builds, exposed binary and asset growth in treemaps, and let teams enforce thresholds in CI. Reaper found unused code. Launch Booster diagnosed startup delays. Distribution put internal builds in testers' hands. Performance Analysis compared two builds on controlled physical devices. Snapshots turned existing SwiftUI and Jetpack Compose previews into visual-regression tests.^[5]
