Which ecommerce platforms do you work with?

Shopify and Shopify Plus are primary. WooCommerce, BigCommerce, and custom stacks are supported. Yaniv runs live Shopify engagements today including Glammie.co.il, Star.co.il, and Shipi.co.il in the Israeli market.

What ecommerce growth levers do you pull first?

Attribution and data layer first — you cannot optimize what you cannot measure. Then product page CRO, checkout flow, email and SMS lifecycle, paid acquisition, and loyalty or subscription mechanics. ICE scored per brand.

Can you run paid media and creative for us?

Yes. Full funnel paid media across Meta, Google, TikTok, and affiliate. Creative strategy, scripting, and production via UGC studios and content factory workflows. Weekly variant cycles tied to MER and blended ROAS targets.

How do you measure ecommerce growth?

MER (media efficiency ratio), blended CAC, contribution margin after ads, 30-60-90 day LTV cohorts, repeat purchase rate, and net new customer count. Weekly P&L and dashboards — no vanity metrics.

What is a typical ecommerce engagement size?

Fractional retainer is $12K-$25K per month for brands doing $1M-$20M revenue. Growth Sprints at $15K fixed scope for narrower problems. Equity hybrid available for venture-backed DTC brands under $3M revenue.

How much does a Fractional Head of Growth engagement cost?

Retainers are $12K to $25K per month depending on scope. Growth Sprints are $15K fixed-scope for 4-6 weeks. Hourly advisory is $200 per hour.

How long is a typical engagement?

Three months minimum, twelve months typical. I leave when your team can run the growth engine without me.

How many clients do you take at a time?

Two to three. Each gets 20 hours a week embedded.

What happens in the first week?

Full growth audit, attribution diagnosis, and a prioritized 90-day plan with measurable outcomes.
