About LTNR

I’m Inna Leitner, founder of LTNR Consulting – a boutique performance marketing studio built around one core idea: do fewer things, but do them exceptionally well.
Over the past 10+ years, I’ve helped e-commerce brands and service-based businesses grow through high-performing Google & Meta Ads. From working at Project A with startups and private equity-backed companies to leading in-house teams managing 7-figure budgets – I’ve seen what works, and what’s just noise.
I started LTNR because I believe businesses deserve real results – not bloated retainers, junior account managers, or vague reports. At LTNR, I personally lead every account, supported by a small group of proven specialists handling tracking, ad creatives, and campaign infrastructure.
We stay intentionally small so we can go deep. No layers. No shortcuts. Just strategy, execution, and clear outcomes you can measure.
If you’ve been burned by big agencies or tired of DIY campaigns that don’t convert, let’s talk. This might be the lean, expert-driven approach you’ve been looking for.
Success Stories

Ergolutions, a German ergonomic furniture maker, needed a marketing boost. As their fractional CMO, I optimized their Google Ads, explored new channels, and prioritized data-driven decisions. This resulted in a 100% YoY revenue growth from Google Ads while keeping efficiency on track. Ergolutions now has a strong performance marketing strategy for continued success.

We helped an established e-commerce brand unlock untapped potential in Google Shopping & Performance Max – boosting revenue by 13% while actually lowering CRR. Through smart feed optimization, ROAS-based bidding, and structured scaling, we turned a flat channel into a growth driver.

Ravensberger Matratzen, a mattress company, wanted to reach new customers. We tackled this by setting up and optimizing their Google Shopping feed, then built a scalable campaign structure for their many products. This data-driven approach led to a significant increase in revenue from Google Shopping, a previously untapped area for them.

Cribb, a recruitment firm for C-Level tech staff, struggled to find the right talent for clients. We built targeted Google Ads campaigs, set up tracking of leads (form fill and call tracking). This resulted in a surge of qualified leads, a lower cost per lead (CPL), and a streamlined recruitment process for Cribb. They’re now exceeding client expectations by consistently delivering top talent.

kfzteile24, a German auto parts retailer, struggled to manage product data for Google Ads. We automated their data feed for account creation, bidding, and scaling, resulting in a +20% revenue growth month-over-month. This freed up their team’s time and allowed for data-driven campaign management.
