Growth Frameworks Compared: AARRR vs RARRA in 2025 Product Strategy
Sep 13, 2023
Product teams are constantly seeking effective ways to measure growth and optimize their strategies. Two frameworks that have dominated the growth hacking landscape are AARRR and RARRA. While one has been the gold standard for years, the other represents an evolution in thinking about customer-centric product development. This article examines both frameworks, their key differences, and how to determine which one might work best for your business in 2025.
What is AARRR Framework?
The AARRR framework, often called the "Pirate Metrics" (due to the phonetic pronunciation "Ar"), was developed by venture capitalist and entrepreneur Dave McClure in 2007. This methodology quickly became the standard growth model for startups and established businesses alike, offering a structured approach to understanding and optimizing the customer journey.
AARRR stands for:
Acquisition: How do users find your product? This stage focuses on bringing users to your product through various channels like content marketing, paid advertising, SEO, social media, and PR campaigns. Key metrics include website visits, app downloads, and cost per acquisition.
Activation: Do users have a great first experience? Activation measures how effectively new users experience your product's core value. This might include completing registration, creating a first project, or achieving an "aha moment" where they recognize the product's benefits. Metrics here include completion rate of onboarding steps and time-to-value.
Retention: Do users come back? Perhaps the most critical metric, retention measures whether users continue to engage with your product over time. Common metrics include daily/weekly/monthly active users, churn rate, and session frequency.
Referral: Do users tell others? This measures how effectively your current users bring in new users through word-of-mouth, referral programs, or social sharing. Metrics include referral rate, virality coefficient, and number of invites sent.
Revenue: Can you monetize these users? The final stage focuses on converting users into paying customers and maximizing their lifetime value. Key metrics include conversion rate, average revenue per user, and customer lifetime value.
The AARRR framework gained significant traction because it provided a logical sequence for optimizing growth: first bring users in, then ensure they have a good experience, encourage them to return, motivate them to invite others, and finally convert them into paying customers.
According to a 2023 report by Product-Led Growth Collective, 67% of SaaS companies still use elements of the AARRR framework in their growth strategy, highlighting its continued relevance despite newer alternatives.
What is RARRA Framework?
The RARRA framework represents an evolution in growth thinking, developed by growth expert Gabor Papp around 2018. This framework essentially reorders the AARRR model to prioritize retention as the first and most crucial element of sustainable growth.
RARRA stands for:
Retention: Can you keep users engaged? In RARRA, retention comes first because the philosophy maintains that without solving retention, other metrics become meaningless. This stage focuses on ensuring users continue to find value in your product over time.
Activation: Do users quickly experience your product's core value? Similar to AARRR, but with increased emphasis on fast time-to-value and streamlined onboarding.
Referral: Do satisfied users recommend your product? The framework acknowledges that only genuinely satisfied users (those you've retained) will make quality referrals.
Revenue: Can you convert engaged users to paying customers? Revenue follows after establishing strong retention, activation, and referrals.
Acquisition: How can you efficiently attract new users? Acquisition comes last in RARRA because the argument is that without solving retention first, acquisition efforts waste resources bringing in users who won't stay.
The key insight of RARRA is that acquisition should be scaled only after you've proven you can retain users. In a 2024 Amplitude product analytics survey, companies that prioritized retention before heavy acquisition spending reported 30% better ROI on their marketing spend compared to those following the traditional acquisition-first approach.
Key Differences Between AARRR and RARRA
The primary philosophical difference between these frameworks lies in their starting points and overall prioritization:
Acquisition vs. Retention Focus: AARRR begins with acquisition, implying that growth starts by bringing in new users. RARRA prioritizes retention first, suggesting that keeping users engaged is the foundation of sustainable growth.
Resource Allocation: According to the 2024 Reforge Growth Report, companies following the RARRA model typically allocate 40-50% of their growth resources to retention initiatives, compared to just 15-20% for AARRR-focused organizations.
Product Development Impact: RARRA tends to influence product development more directly, as it pushes teams to solve retention problems before scaling acquisition. This often results in more user-centric product decisions.
Market Maturity Considerations: AARRR may be more appropriate for entirely new markets where user education and acquisition are genuine barriers. RARRA tends to work better in established markets where user expectations are already set.
Loop Closure: While AARRR presents a somewhat linear journey, RARRA creates a tighter feedback loop that emphasizes the cyclical nature of product growth.
As Andrew Chen, general partner at Andreessen Horowitz, noted in his 2023 analysis: "The shift from AARRR to RARRA reflects the broader market shift from growth-at-all-costs to sustainable unit economics and genuine product-market fit."
Implementation Strategies for Both Frameworks
Implementing AARRR
When implementing the AARRR framework, consider these strategies for each stage:
Acquisition Strategy: Focus on diversifying acquisition channels while tracking cost-per-acquisition. Implement attribution modeling to understand which channels deliver the highest quality users.
Activation Strategy: Map the critical path to value and remove friction points. Create guided onboarding flows that lead users to their "aha moment" as quickly as possible.
Retention Strategy: Segment users based on engagement patterns and create personalized re-engagement campaigns. Identify leading indicators of churn and address those issues proactively.
Referral Strategy: Build referral mechanics directly into the product experience at moments of high user satisfaction. Make sharing frictionless and consider double-sided incentives.
Revenue Strategy: Experiment with pricing models and entry points. Create clear upgrade paths and identify opportunities for expanding customer value.
A compelling example comes from productivity app Notion, which initially focused heavily on acquisition through content marketing and a free tier, then systematically optimized each subsequent stage of the AARRR funnel.
Implementing RARRA
For the RARRA framework, implementation looks somewhat different:
Retention Strategy: Start by defining what meaningful retention looks like for your product. Identify core features that drive ongoing engagement and build engagement loops around them.
Activation Strategy: Design onboarding to deliver value within the first session. Measure and optimize time-to-value relentlessly.
Referral Strategy: Identify your most retained users and analyze what makes them successful. Build referral opportunities based on their usage patterns and moments of delight.
Revenue Strategy: Align pricing with value metrics that correlate with retention. Consider usage-based or value-based pricing models.
Acquisition Strategy: Once other elements are optimized, scale acquisition channels that bring in users similar to your most successful segments.
Streaming platform Spotify exemplifies the RARRA approach, focusing initially on creating personalized experiences that retain users (through recommendations and playlists), then leveraging that engagement for referrals and conversion to premium subscriptions, before scaling acquisition efforts.
Case Studies: Success Stories with Both Frameworks
AARRR Success: Dropbox
Dropbox's early growth strategy perfectly exemplifies the AARRR framework:
Acquisition: They used a simple landing page with an explainer video and waiting list to generate initial interest.
Activation: Their onboarding process was streamlined to get users storing their first file quickly.
Retention: They created desktop integration that made the service part of users' daily workflow.
Referral: Their famous referral program offered free storage space for both the referrer and the new user, driving viral growth.
Revenue: They converted free users to paid plans once they approached storage limits.
This systematic approach helped Dropbox grow from 100,000 to 4 million users in just 15 months, according to their early growth metrics.
RARRA Success: Slack
Slack's growth story aligns closely with the RARRA model:
Retention: They focused obsessively on creating a product that teams would use daily, with features designed for ongoing engagement.
Activation: They streamlined the onboarding process to get teams communicating quickly and integrated with popular work tools.
Referral: They leveraged network effects by making it easy to invite team members and other teams within organizations.
Revenue: They implemented a freemium model with clear value upgrades for teams that needed more features.
Acquisition: Only after perfecting the above did they scale marketing efforts significantly.
According to a 2023 Product-Led Institute report, Slack achieved a remarkable 8-10% weekly growth rate during its early scale phase using this approach, with 93% of their growth coming from existing user retention and referrals rather than direct acquisition spending.
Choosing the Right Framework for Your Business
Selecting between AARRR and RARRA depends on several factors:
Business Model Considerations: Subscription-based businesses typically benefit more from RARRA due to the importance of ongoing retention. One-time purchase products might find AARRR more appropriate.
Market Position: New market entrants may need to emphasize acquisition first (AARRR), while companies in crowded markets often benefit from focusing on retention (RARRA) to differentiate.
Available Resources: RARRA typically requires fewer initial marketing resources but demands more product development focus. AARRR might require more significant marketing investment upfront.
Data Maturity: Implementing RARRA effectively requires robust product analytics capabilities to measure and optimize retention properly.
According to the 2025 McKinsey Digital Growth Report, companies that align their framework choice with their business model and market position outperform those using misaligned frameworks by an average of 27% in year-over-year growth.
Future Trends in Growth Metrics
As we look toward the latter half of 2025, several trends are emerging in how companies approach growth frameworks:
AARRR+C and RARRA+C: Both frameworks are increasingly adding "Community" as an additional metric, recognizing the growing importance of community-led growth in sustainable business models.
AI-Optimized Frameworks: Machine learning is being applied to dynamically adjust framework priorities based on real-time user behavior, creating more responsive growth systems.
North Star Integration: Growth frameworks are being more tightly integrated with North Star metrics to ensure alignment between growth tactics and overall business objectives.
Sustainability Metrics: Environmental and social impact measurements are being incorporated into growth frameworks, particularly by B2C companies targeting younger demographics.
The 2025 OpenView Partners State of Product-Led Growth report indicates that 42% of high-growth companies now use hybrid approaches that borrow elements from both AARRR and RARRA, adaptively applying different frameworks to different user segments or lifecycle stages.
Conclusion
Both AARRR and RARRA offer valuable frameworks for structuring your approach to product growth. While AARRR has been the traditional standard with its logical progression from acquisition to revenue, RARRA represents an evolution in thinking that prioritizes sustainable growth through retention-first strategies.
The most successful companies in 2025 are those that understand the principles behind both frameworks and apply them contextually rather than dogmatically. By recognizing where your product and market stand, you can make an informed decision about which framework will best serve your growth objectives.
Consider evaluating your current metrics through both lenses to determine where your greatest opportunities for improvement lie. Would focusing more resources on retention dramatically improve your overall funnel efficiency? Or do you need to solve acquisition challenges before retention becomes your limiting factor?
