Performance Rescue
Find and fix the React Native bottlenecks that make your app feel slow, brittle, or risky to ship.
Founded Labs helps product teams move from vague performance concerns to measured bottlenecks, targeted fixes, and release confidence.
- Focus
- Measured bottlenecks
- Useful for
- Slow or risky releases
- Output
- Fix plan or implementation
01Who this is for
Built for teams with a real React Native decision to make.
- 01
Teams with a React Native app that feels slow but lacks a clear bottleneck map.
- 02
Product teams approaching an important launch where performance risk is visible.
- 03
Engineering leaders who need senior help distinguishing architecture issues from isolated hot paths.
02Problems this solves
The risk that quietly stalls a roadmap.
- 01Startup time is hurting first impression or conversion.
- 02Navigation feels delayed, sticky, or unpredictable.
- 03Rendering issues create jank on important screens.
- 04Slow lists or complex screens are degrading core workflows.
- 05Native module hotspots or bridge-heavy work are affecting responsiveness.
- 06Crash and error observability is not strong enough to support confident release decisions.
03Scope
What Founded Labs reviews or implements
- 01Startup path, bundle loading, app initialization, navigation setup, and first useful screen timing.
- 02Screen-level rendering behavior, memoization boundaries, list configuration, and expensive state updates.
- 03Native module hotspots, bridge usage, data serialization, and platform-specific bottlenecks.
- 04Crash, error, and performance observability signals that affect release confidence.
- 05Targeted fixes for the highest-leverage bottlenecks when implementation is in scope.
- 06Release validation plan so improvements can be measured and protected.
04What you get
What you walk away with.
- 01A ranked performance risk map tied to user-facing screens and release goals.
- 02Concrete fixes or implementation support for the highest-impact bottlenecks.
- 03Measurement guidance so the team can verify progress before release.
- 04Recommendations for observability, regression prevention, and future performance ownership.
Example outcomes
- 01The team knows which bottlenecks are real and which are symptoms.
- 02High-priority screens become more responsive and easier to reason about.
- 03Release risk is reduced because performance changes are measured.
- 04Engineering gets a maintainable plan for preventing regressions.
05How we work
A senior, founder-led engagement.
What you provide
- Representative devices, builds, repro steps, and affected workflows.
- Repository access and profiler-compatible build access where possible.
- Crash, error, analytics, and performance traces when available.
- Product context for which screens and flows matter most.
Engagement shape
- Can start as a diagnostic or a focused performance sprint.
- Scope is organized around user-facing flows, devices, and measurable bottlenecks.
- Implementation support is prioritized by impact and release timing.
- Pricing is scoped to the depth of investigation, app complexity, and fix surface area.

06FAQ
Common buyer questions.
No specific metric is guaranteed before measurement. The work is structured to identify real bottlenecks, prioritize high-leverage fixes, and verify outcomes against agreed signals.
No. React rendering, startup work, navigation, lists, native modules, build configuration, and observability can all affect React Native performance.
Often, yes. The scope should be narrowed to the workflows and release risks that matter most for the launch window.
