What 358 does

358 (legal entity: ThreeFiveEight Oy) is a Helsinki-based, people-centric creative agency founded in 2008 that delivers brand strategy, brand identity design, and customer experience services to enterprise and growth-stage clients across Finland and selectively internationally. The agency's offerings are organized around three interconnected pillars: Human Understanding (research, insights, segmentation, trend mapping), Brand Services (strategy, positioning, brand architecture, visual and verbal identity, design systems), and Experience Services (customer journey mapping, UX/UI design, loyalty programs). It also operates a specialized Gen Z branded entertainment series and publishes free methodology tools such as a Customer Journey Map template.

The operating model is professional services: project-based, quote-driven engagements staffed by a multi-disciplinary team of approximately 15 professionals spanning insight strategy, design, video, copywriting, and project management. Sales motion is direct and founder/CEO-led, with inbound directed to the CEO's email and a Calendly-based 30-minute intro meeting. Distribution is regional (Helsinki, Finland), with international reach through individual cross-border client mandates rather than a local presence abroad. Tooling stack is standard SME/business (Webflow, Google Workspace, Microsoft 365, ActiveCampaign, Google Analytics, Google Ads, Meta Ads).

358 is independently owned by its team ("Owned by us!") with no disclosed external investors, no parent company, no subsidiaries, and no M&A history. Revenue, pricing, and financials are not publicly disclosed. Long-tenured client relationships — including Nelonen Media since 2010 and Asuntomessut annually since 2021 — anchor retention. Documented client outcomes include R-Kioski's 20% merchant results uplift, Fresh Servant's 300% sales increase over three months, Netvisor's +93% brand awareness / +132% consideration / +53% preference gains, and 83% YouTube view-through rates on Vaasan Sähkö campaigns.
