Case Study: Nutrabolt turns a community-first influencer strategy into a content machine and drives 479% campaign ROI with Aspire

How a fitness company transformed its community-first influencer strategy into a successful content machine

Nutrabolt, the parent company behind C4 and XTEND, turned to Aspire to scale a community-first influencer strategy across its diverse global audience. Faced with managing hundreds of relationships—from DMs to pro athlete partnerships—and removing personal bias in influencer selection, Nutrabolt needed a system of record and discovery tools (Aspire Connect and Aspire Manage) to formalize relationships and automate time‑consuming processes like contracting, licensing, and payments.

Using Aspire’s platform to vet creators, streamline collaborations, and repurpose authentic content, Nutrabolt produced 1,000+ pieces of content, gained ~34–35K Instagram followers, and drove millions of impressions (11.8M–14M+ across campaigns). Aspire-enabled activations—including the C4 Fitness Summit and athlete launches—delivered measurable impact: 479% campaign ROI, tags/mentions in 400+ Instagram stories, an attendee NPS jump from 2.3 to 4.9, the highest‑ever single‑day XTEND sales with 90% new customers, and contributed to Nutrabolt’s broader results ( ~$650M retail sales, 150% online sales growth).
