# OneZero > OneZero is a boutique performance marketing agency based in Riga, Latvia, helping ambitious DTC ecommerce brands grow through email marketing (Klaviyo), performance marketing, 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.
