# OneZero > OneZero is a boutique performance marketing agency based in Riga, Latvia, helping ambitious DTC ecommerce brands grow through email marketing (Klaviyo), performance marketing, media buying, and conversion rate optimization. We work like an in-house team — not an external vendor — and treat client brands like our own. OneZero's edge is depth over breadth: we focus on three things — email automations, campaigns, and deliverability — and execute them with senior-level operators across every account. We are Klaviyo, Shopify, and Meta partners. Email programs we run typically generate 25–35% of total ecommerce revenue. Founded by Ilja Olijevskis in 2018. Based in Riga, Latvia. Operates worldwide, with concentration in Northern Europe and North American DTC brands.
