Rolodex Acquires Cosmonos — Expanding Our Investment Banking Prep Platform

Rolodex acquires Cosmonos to accelerate investment banking career success

Today, we're thrilled to announce that Rolodex has acquired Cosmonos.io, a pioneering investment banking preparation platform known for its innovative approach to technical training and career development. This strategic acquisition brings together two companies with a shared mission: democratizing access to investment banking careers while maintaining the highest standards of preparation quality. By combining Cosmonos's technical excellence with Rolodex's proven banker mentorship model, we're creating the definitive platform for investment banking career preparation.

Why Cosmonos and why now

Cosmonos has built something special. Their platform has helped hundreds of candidates master the technical skills required for investment banking through interactive learning modules, real-world case studies, and adaptive practice systems. What impressed us most wasn't just their technology — it was their philosophy. Like Rolodex, Cosmonos believes that talent exists everywhere, but opportunity doesn't. Their tools have made institutional-quality training accessible to students regardless of their school or background.

The timing of this acquisition reflects the evolving landscape of investment banking recruiting. Technical bars continue to rise, with firms expecting deeper modeling expertise and market knowledge from day one. Meanwhile, the window for preparation keeps shrinking as recruiting timelines accelerate. Candidates need comprehensive preparation that's both rigorous and efficient. This acquisition allows us to deliver exactly that.

What this means for our users

• Enhanced technical training: Cosmonos's adaptive learning algorithms will be integrated into our curriculum, providing personalized technical skill development that adjusts to each user's pace and proficiency
• Expanded content library: Addition of 200+ hours of technical content, including advanced modeling tutorials, sector-specific deep dives, and interactive case studies
• Self-paced learning options: While maintaining our signature cohort model, we'll now offer self-paced technical modules for candidates who need flexibility
• Broader accessibility: New pricing tiers and scholarship opportunities to serve more candidates across different backgrounds and circumstances
• Continuous learning: Post-placement resources for analysts navigating their first years on the job

Strengthening our core differentiators

This acquisition amplifies rather than replaces what makes Rolodex unique. Our live banker-led sessions, personalized mock interviews, and warm introductions to target firms remain central to the experience. Cosmonos's capabilities enhance these differentiators by ensuring every candidate arrives at these touchpoints with rock-solid technical foundations. When our banker mentors conduct mock interviews, they can now focus on advanced topics and nuanced feedback rather than basic concepts.

The combined platform addresses the full spectrum of preparation needs: technical mastery through Cosmonos's adaptive systems, practical application through Rolodex's live sessions, and career placement through our banker network. No other platform offers this complete ecosystem.

Integration roadmap

• Immediate access: Current Rolodex members gain instant access to Cosmonos's full content library
• Q4 2025: Technical skills assessment integration to create personalized learning paths
• Q1 2026: Unified platform launch with seamless experience across all features
• Q2 2026: AI-powered interview simulator combining both platforms' expertise
• Ongoing: Continuous content updates based on latest recruiting trends and user feedback

Message to the Cosmonos community

To the Cosmonos community: we're honored to continue your journey with us. Your platform has set the standard for technical excellence in investment banking preparation. We're committed to preserving what you've built while accelerating its impact. All existing Cosmonos subscriptions will be honored with additional Rolodex benefits at no extra cost. The Cosmonos founding team will continue leading product development, ensuring the innovation that defined your platform continues.

Looking forward

This acquisition represents more than combining two platforms — it's about reimagining how the next generation of investment bankers prepare for their careers. The traditional path to investment banking has favored those with institutional advantages: target school pedigree, family connections, and access to expensive coaching. We're building something different: a meritocratic pathway where preparation quality, not circumstance, determines success.

Together with Cosmonos, we're not just preparing candidates for interviews — we're preparing them for careers. Our vision extends beyond placement to long-term success, providing the foundation for our users to become the industry leaders of tomorrow. This acquisition accelerates that vision, bringing institutional-quality preparation to every ambitious candidate, regardless of their starting point.

To our combined community of future bankers: the best is yet to come. The integration of these platforms will create opportunities we couldn't deliver independently. Your feedback has shaped both platforms, and it will continue guiding our combined path forward. Thank you for trusting us with your career preparation. We can't wait to show you what we're building together.
