From Startup Sprint to Acquisition Finish Line: How Flow Guys Powered Runna's Hypergrowth on Webflow

Witnessing a client achieve phenomenal success is one of the most rewarding aspects of what we do. Runna, the AI-powered running coach app, is a prime example. Launched in 2021, they experienced explosive growth, attracting hundreds of thousands of users globally and ultimately being acquired by fitness giant Strava in April 2025.

We've had the privilege of being Runna's dedicated Webflow development partner since 2023, right through their critical hypergrowth phase. Their journey perfectly illustrates the challenges fast-moving tech companies face and how the right platform, combined with an expert, agile partner, can be instrumental in achieving ambitious goals.

If you're scaling a tech business, Runna's story might sound familiar.

The Challenge: Keeping a High-Performance Website Pace with Hypergrowth

Runna's rapid expansion meant their website couldn't just be a static brochure. It needed to evolve constantly and perform flawlessly under pressure. They faced hurdles common to many scaling tech companies:

1. Evolving Beyond a Marketing Site: Runna needed their Webflow site to transform into a comprehensive online resource hub for runners – a dynamic space for content, advice, and community engagement. This required more than just adding pages; it demanded a scalable content strategy built on a flexible platform.
2. Mastering Complex Integrations: As operations grew, seamlessly connecting their website to crucial business systems became vital. Specifically, they needed to integrate HighTouch to pull and display data for thousands of global running events directly within Webflow, and AppsFlyer to accurately track multi-platform app download conversions – essential for marketing ROI. These weren't simple plugin jobs; they required robust, custom solutions.
3. Matching Startup Speed: Runna moved fast. Marketing campaigns, feature launches, and content updates needed to happen in days, not weeks. Without a large internal web team, they couldn't afford development bottlenecks. They needed a partner and a platform built for speed and agility.
4. Finding a Reliable, Flexible Partner: The startup journey is rarely linear. Runna needed a partner who could adapt to fluctuating development needs – scaling support up for big pushes and providing steady maintenance during quieter periods – without the rigidity of traditional agency contracts.

Our Solution: Agile Expertise Meets Webflow's Power

Runna had chosen Webflow as their platform, giving us a powerful foundation to build upon. Here's how we, as their dedicated Webflow agency, tackled their challenges:

• Leveraging Webflow for Speed and Scale: We utilized Webflow's visual development capabilities to rapidly build and iterate on pages, matching Runna's pace. Its powerful CMS was the backbone for evolving their site into the resource hub, allowing for efficient management of a growing content library. Importantly, Webflow Editor empowered Runna's own team to make quick content updates easily, fostering self-sufficiency.
• Building Complex Integrations: Our team expertly handled the crucial integrations. We built a custom solution to pull dynamic event data from HighTouch into the Webflow CMS, keeping their event listings constantly up-to-date. We also implemented the AppsFlyer integration for precise app download tracking. Webflow's ability to handle custom code and robust integrations without relying on a fragile plugin ecosystem was key to building these stable, essential connections.
• Providing Flexible, On-Demand Expertise: Our subscription model was designed for exactly this scenario. It gave Runna continuous access to our specialized Webflow skills – design, development, project management – adapting to their needs month by month. No rigid scopes, no wasted resources, just the support they needed, when they needed it.
• Acting as a True Partner: We integrated seamlessly with the Runna team, using efficient communication channels like Slack. We weren't just an external vendor; we were an extension of their team, focused on proactively solving problems and delivering results with minimal friction.

The Results: A Website That Fueled Growth

Our partnership, amplified by Webflow's strengths, delivered tangible benefits for Runna:

• A Dynamic Online Hub: Their website successfully evolved into the valuable resource they envisioned, boosting engagement and supporting user acquisition.
• Rock-Solid Integrations: The complex HighTouch and AppsFlyer integrations worked flawlessly, providing essential data for operations and marketing.
• Unhindered Agility: Web development kept pace with Runna's rapid growth, never becoming a bottleneck.
• Strategic Focus: Critically, by entrusting their Webflow presence to us, Runna's internal engineering team could concentrate 100% on their core AI coaching app – the engine of their success. We handled the web complexities, allowing them to innovate faster.
