+51% ROI | FinTech App
Zero lifecycle in place. Users were dropping off at every step of the onboarding flow. I built end-to-end activation sequences that pushed users through each stage – card issued, card activated, first purchase.
Signups don't convert. Customers churn. Ad spend climbs.
I build the lifecycle system that fixes all three.
Automated onboarding, retention, and re-engagement flows for SaaS and FinTech – so you stop losing revenue to broken customer journeys.

What I've delivered
+31% paying customers | SaaS
Signups briefly explored the product then ghosted. I found the pattern that predicts who will pay – and built flows that nudge the rest to get there.
–26% churn | Crypto App
Users deposited funds for a promotion then withdrew everything and disappeared. I identified behavioral signals that predicted withdrawals and set up flows that kept users engaged before and after they withdrew.
+34% LTV | FinTech App
Users got their card, made one purchase, then forgot about it. I built AI-driven recommendation flows that suggested purchases based on each user's profile and behavior – different recommendations for every user.
Why CMOs and Founders Choose Me
Companies without lifecycle systems fall behind on activation and retention
Agencies send pretty emails and campaigns that don't move your core metrics
Consultants deliver solid strategy but disappear before anything gets built
I own both strategy and execution and deliver systems that produce measurable results

Common questions
What if our data is messy?
Not a problem. I clean and structure it myself before building any flows – even if it's spread across Excel sheets or raw backend exports.
What if our IT team is busy?
I handle integrations myself. Your IT team only needs to be involved at the very beginning to grant access – after that it's on me.
What if our emails land in spam?
I've fixed deliverability issues before. We'll sort it out before launching any campaigns.
What if we have legal or regulatory restrictions?
I work with industry-specific regulations in FinTech and Crypto, so compliance is already part of how I build.
I'm Serafim Ivanov
For the last 7 years I've been building lifecycle systems for SaaS and FinTech companies that turn signups into paying customers who renew.
I worked in-house at FinTech and SaaS companies, which means I understand how these businesses actually operate – not just the marketing side, but the product, the data, and the technical constraints.
I don't just advise. I build. From strategy to execution, I own the entire system and deliver results you can see in your metrics.
