I’m Martynas Stonys. I run Meta Ads, Google Ads and Klaviyo for online shops spending €2–10k a month on ads.
I put your budget where it earns the most, and every month you get the next steps in writing.
If the leaks I find don’t add up to €490 a month, you don’t pay.

Static ads and catalogue images, each built for one job: a price, a comparison, a deadline. The catalogue images come from my own tool, straight from your product feed. New versions go up against the current best.
How it starts
Money first, then the ads. Here’s what happens after you say yes.
Margins, order values and what a customer is worth over time. Those numbers set what you can afford to pay for a sale.
I fix the biggest leaks first: overlapping campaigns, weak feeds, budgets in the wrong place and the wrong conversion goals.
New ads and emails go live, each one set up as a test so we can tell what worked.
What changed, what it did and what I’ll do next, in writing, in English or Lithuanian. Then one every month.

About
Swing Ahead is a one-person company. The person on your first call is the person working in your ad account.
I moved into marketing in 2020, when Covid hit, working in an agency and freelancing on the side. The name Swing Ahead comes from swing dancing.
FAQ
The short answers. Anything else, ask me on email or WhatsApp.
The leak audit is €490, and the fee comes off your first month if you hire me. Setting up a new ad account starts at €500. Ongoing management is €350 a month plus a share of ad spend above an agreed level, so your fee only grows when you choose to spend more. Prices exclude VAT.
The written audit puts a monthly euro value on each leak, worked out from your own numbers. If together they don’t add up to €490 a month in savings or extra sales, you don’t pay for the audit. That’s 3× the fee within three months, and it’s settled the day you get the report.
Fixing leaks shows in the first month, because it stops money going out. Growth from new campaigns and email flows takes longer: give it two to three months before you judge it.
You do. Ad accounts, pixels, Klaviyo and all the data stay in your name. I work in them with access you can remove at any time.
No. Work runs month to month, and either of us can stop with 30 days’ notice.
I do. Swing Ahead is a one-person company, so the person on the first call is the person in your ad account, building your emails and writing your monthly update.
Access to your Meta and Google ad accounts, Klaviyo if you use it, and your shop’s order data. Then about an hour in the first week to talk through margins and goals.
Online shops spending roughly €2,000 to €10,000 a month on ads, on Shopify, WooCommerce or PrestaShop, selling in Lithuania, the UK and beyond. I also work with event organisers, lead-generation businesses and dance schools.
