Grab Cuts ANRs 32%, Boosts Startup 35% with R8
Southeast Asian superapp Grab optimized its Android app with R8 code shrinking, Baseline Profiles, and Profile Guided Optimization. The initiative reduced user-perceived Application Not Responding (ANR) rates by 32.5%, cut download size by 30.4%, and improved cold start time by 35%. Rolled out in phases during 2025 and 2026, Grab migrated from legacy ProGuard to R8 Compat mode, then Full mode, and refined keep rules. The migration addressed a 10-year-old codebase with over 10 million lines of code. R8's permanent structural advantage ensures future code expansion won't proportionally bloat app size, crucial in the AI-assisted development era. The team plans CI guardrails to maintain optimization scores.
This case study demonstrates effective use of Android optimization tools, but it is not a new product or major platform change. It highlights best practices for app developers, relevant to the broader tech ecosystem but not directly impacting AdTech or MarTech industries.

Grab unveils AI to reshape in-app brand discovery
At its GrabX 2026 event, Grab Holdings announced 13 new AI-driven features intended to change how users discover and transact inside the Grab app. The updates span transport, food delivery and payments and introduce tools branded as “Everyday AI Companions,” an in-app Discover feed, assistant features for merchants (including a “virtual store manager”) and voice assistants for drivers. Grab says these capabilities are powered by an "Intelligence Layer" trained on data from over 20 billion rides and orders. The company positions the app as a recommendation and transaction hub rather than a simple query/response tool. Rollout is at an early stage and will vary by market; the move could shift discovery and marketing dynamics in Southeast Asia by increasing merchant dependence on Grab’s ranking and recommendation systems and raising transparency questions about algorithmic visibility.
Grab says AI speeds product shipping over 30%, raises forecasts
Grab reported record second-quarter results and raised its full-year guidance after strong consumer demand across Southeast Asia. CFO Peter Oey said AI is embedded across the business and has helped the company ship products more than 30% faster, improving margins and cost-efficiency. Q2 revenue grew 22% year-over-year to $997 million, operating profit rose to $19 million (up 186%), and ride volumes increased 28% year-on-year. Grab raised its full-year revenue outlook to $4.10–$4.15 billion and lifted EBITDA guidance to $720–$740 million. The company said it is working to close its acquisition of Delivery Hero’s foodpanda delivery business in Taiwan in the second half of the year. Nasdaq-listed shares rose in after-hours trading.
AI Apps Boom, But Usage Lags Behind
A recent analysis by a16z's Charts newsletter reveals a surge in app creation driven by AI code generation tools, but demand has not kept pace. While new app submissions across iOS, Android, and Chrome have doubled or quadrupled, downloads and ratings have remained stagnant. The share of apps achieving meaningful traction (10+ ratings or 100+ downloads) has plummeted, indicating a wave of 'App-Slop.' SensorTower data shows US app revenue nearly flat, with modest increases in usage time. AI-powered apps like ChatGPT, Claude, Gemini, and Grok lead growth in the Productivity category. The article also discusses the changing venture landscape, noting AI's role in creating younger, faster-growing unicorns, a shift in VC focus towards profitability, and a rise in B2B SaaS shutdowns.
