I help Shopify subscription brands get more new customers to buy again, stay subscribed longer, try the right next product, and leave more proof. I do that by installing my own software-backed LTV system behind the customer path.
Find the best customer path.
I identify your highest-LTV customers, what they bought first and next, how fast they bought again, which offers brought them in, and which actions made them more valuable.
Build the customer value data layer.
My system shows which customers become more valuable and where others fall off:
Install the systems that move customers along that path.
The exact build depends on what your brand needs most. It can include:
Turn it into an operating rhythm.
The work becomes clear decisions your team can use, not another dashboard to ignore:
Shopify subscription brands where the first purchase is not the whole business.
The simplest fit is setup plus ongoing support: install the system, establish the reads, then keep improving the customer path as the data shows what gets people to buy again, stay subscribed, and become more valuable.
I'm Piotr. I've worked on ecommerce growth since 2016, starting as a freelance developer building landing pages and fixing other agencies' work, then founding Carybit, a CRO agency, in 2022.
This is founder-led work, not a handoff to a junior team. I built the software, data layer, and playbooks I install, then stay close to the work as it starts changing the customer path.
Through Carybit I ran CRO programs for multiple ecommerce brands at $100M+ in annual revenue. The agency side is sunset. The quiz-funnel software I built there still serves paying ecommerce customers today.
Before any of that, I played professional tennis for 12 years. Not a credential for advising on growth, but it's where my standards came from.
Why I build this way:
A builder's view of LTV.
Most growth work stops at recommendations. My background is software, CRO, and Shopify implementation. I have built the pages, tools, and systems myself, so I know what can actually change the customer path after the first order and what will turn into busywork.
Real depth on AI, not the hype version.
Most operators selling "AI workflows" in DTC don't have the technical foundations. I'm a developer who's worked through the actual material, including Karpathy's ML and LLM lectures end-to-end. I can tell you which AI workflows will actually move your business and which are half-baked.
I read outside DTC on purpose.
Most growth and CRO advice stays inside DTC, with customer psychology reduced to surface tricks (urgency, scarcity, social proof). I work from frameworks and research outside that bubble: hospitality (Unreasonable Hospitality, Ritz-Carlton's excellence model) and customer psychology (Cialdini on influence, Kahneman on decision-making, Schwartz on awareness levels). I bring them in when they fit.
