Growth & Product Marketing

'sup! I'm Lazar

Product Marketer, Growth Marketer, and Go-to-Market Operator for early-stage SaaS, DevTools, and EdTech B2B & B2C startups.

Acquiring new customers is damn hard.

Sadly, SaaS growth is stuck in the previous decade.

You're chatting with marketers about your SaaS growth and you're getting the same answer every time: top-down, funnel-based activities... Pour more in. Get more out. Hopefully.

Top-down marketing approach makes your teams operate in silos — everyone trying to figure their shit out and working on goals they are biased about. Yet, on every quarterly meeting, you're seeing sales and marketing teams misaligned and dysfunctional.

For decades, this worked. But when you take a step back and look at how that growth curve grew over time, it feels linear.

97% of marketers still praise the top-down approach. Me and the 3-percenters praise embedding marketing into the product and using product as the biggest growth lever.

The mantra is simple: acquire users by showing them where they are and where they can be, handhold and guide them to feel the promised value within the first hour, build trust by showing them that it actually works, utilize product usage, company, and intent signals to know when is the right time to ask them for more money, and shape your business with them so they feel a sense of ownership and rave about you in every occasion.

This approach allowed me to acquire more than 250k users and $3M in revenue for bootstrapped EdTech and B2B & B2C SaaS, DevTools, and Marketplaces backed by angels and VCs like Accel, Salesforce Ventures, Sequoia's Surge, CRV, and more.

What I do

Building predictable growth engine

I've been lucky enough to be a one-man army, as well as to scale marketing teams from 1 to 15 in a matter of months. This allowed me to tackle product marketing, growth, and sales activities, and to get the best out of them to build a predictable growth engine.


Building predictable acquisition engine by embedding marketing into the product.


Crafting onboarding and feature adoption flows to handhold users to see the value within the first hour.


Building trust by showing that it actually works through conversion-focused and user generated content.


Building product-led sales with first-party, product usage signals and third-party, intent signals.


Turning users into raving fans by building retention models and word of mouth loops that scale exponentially.

Giving back

Helping founders and marketers skip the trial-and-error

Giving back to the community has been my number one priority. That's why I dedicate my time to mentor startups and marketers and share my fails, stories, and processes.

Wow! I'm still reeling from the session. What really differentiates Lazar is how practical he is. He only recommends something he has done recently himself, and he goes as far as taking you through the screens to show you how to do it. He is the true archetype of a growth hacker, living his experiments and walking his talk.

We've been stuck at a plateau from trying the same old marketing tactics that every company is familiar with. Lazar has really found some unique angles to grow SAAS users that target the people facing problems their product has a solution for. I had some amazing takeaways and a clear path on what to focus on in our industry. :)
