Helping SaaS Founders grow their businesses to $10M+ ARR

I started SaaStock in 2015 with a simple idea: give SaaS founders a real space to connect, learn, and scale faster–together.

Fast forward to today: SaaStock has become the global home for SaaS founders who are serious about growth.

We've hosted thousands of founders, VCs, and execs from Dublin to Austin, from seed stage to unicorn. We’ve built a community that doesn’t just celebrate scale, it shares the hard truths, the breakthroughs, and the lessons you only get by being in the room where it happens.

Before SaaStock, I spent 11 years in sales, getting my hands dirty, chasing targets, closing deals, and learning what real GTM pressure feels like. That experience taught me: there’s no shortcut to growth. You need the right people around you, the right mindset, and a willingness to evolve — especially now, in an AI First world.

Today, I'm focused on three things:

Growing SaaStock across Europe and the US as the leading platform for SaaS founders.

Building a new generation of founder-driven, AI-enabled companies.

Using the SaaS Revolution Show Podcast to tell the real stories — the wins and the war stories — from the frontlines of SaaS.

SaaS is changing fast.

I'm here for the builders who want to change with it and win.

If you're scaling a SaaS company, or investing in one, let's chat.

Founder

Our purpose is to make a real difference to the lives and companies of the SaaS community

Most SaaS companies fail within the first three years due to lack of runway, lack of product market fit and lack of founder experience in managing a business.
SaaStock helps B2B SaaS Founders on the journey to $10mill ARR supercharge their growth by connecting founders with VCs to help extend runway, learn from industry experts and build pipeline.
We do this through or Physical and virtual conferences, our founder membership program, SaaStock local community gatherings and media.
We are the only media and events business that focuses on SaaS founders scaling to $10mill ARR. This focus enables us to provide the highest quality events, content and connections
For founders in this stage of their journey.


It’s a scary, uncertain — and incredibly exciting — moment in SaaS.
Earlier this week, a founder said to me:

“We may be living through the most pivotal 12 months in SaaS history.”

He might be right.

AI isn’t just another feature wave. It’s a platform shift. Business models are changing. GTM motions are evolving. Defensibility is being redefined in real time.

That’s exactly why we’re bringing 50 B2B SaaS leaders together in Austin next week Thursday 25th Feb for SaaStock Local: Austin.

No panels.
No fluff.
No vendor pitches.

Just a curated room of founders and operators having honest, peer-to-peer conversations about:

• How they’re adapting their product strategy
• Where AI is creating real leverage (vs noise)
• What’s changing in GTM and revenue models
• How to stay relevant — and win — through this shift

Running the largest 1:1 Meetings event in B2B Software

The B2B software model is being rewritten. Not gradually. Right now.

I've been speaking to SaaS founders across the spectrum lately, and the honest truth? The smartest people in the room are wrestling with the same fears.

Am I still building a product — or just a feature someone else's AI will absorb? Should every workflow become an agent? 
Will my pricing model survive when buyers only want to pay for outcomes? 
Is PLG quietly breaking?

These aren't hypothetical questions. They're keeping founders up at night, and they deserve real answers — not thought leadership, not hot takes, not another webinar.

That's exactly why April 15-16 in Austin matters more than any other two days on your calendar this year.

SaaStock USA is bringing together the B2B software leaders who are already running the experiments — testing AI packaging, rethinking seat vs. usage models, rebuilding GTM around agents, and winning. 

The people who've already paid the tuition of trial and error, so you don't have to.

Two days. Your peers. Structured 1:1 conversations with the founders actually navigating this shift in real time.

Not panels. Not theory. Intelligence you can act on straight away.

The AI platform shift doesn't reward the smartest founders. It rewards the best-informed ones moving fastest. Every month you spend figuring this out alone is a month a competitor spends learning from someone who already solved it.

SaaStock USA 15th and 16th April will be the room where that changes. Austin will become the AI intelligence hub for 2 days.

If you're building B2B software in 2025 and you're not in this room, you're navigating one of the biggest platform shifts in a generation without a map.

B2B marketing is being rewritten in real time. Are you keeping up?

Next week in London, 4th March, SaaStock is bringing together our community for an intimate afternoon with one of the sharpest minds in B2B SaaS marketing — Kady Srinivasan, CMO at Freshworks.

Kady has built and scaled marketing at Dropbox, Klaviyo, and you.com. She's flying in from San Francisco and is giving us her afternoon to dig into something every B2B marketer is grappling with right now:

→ How AI is fundamentally changing B2B buying behaviour
→ What GTM motions actually work in 2026
→ Where most SaaS companies are getting it wrong — and what to do instead

This is an intimate SaaStock community session. Only 25 spots remain.

If you're a founder, CMO, or marketing leader trying to figure out what 'good' looks like in the AI era — this is the room to be in.

Founder, P33 | Executive Thought Leadership Agency

Helped 50+ B2B tech companies build their Founder/CEO Brand and implement Executive Thought Leadership Programs for LinkedIn. Customers, results & process: project33.io

About me:

I'm Finn, 29, grew up in Bremen, Germany, studied Physics & Philosophy in Heidelberg for 3 semesters, dropped out of college in 2017 because I was doing it for other people, flew to New York with no plans, documented the journey on Linkedin, Instagram and Youtube, and started my first company (Project 33) on the back of having grown a small audience. We're a small remote agency that helps B2B founders & execs create thought leadership content for Linkedin.

In my free time, which I try to have as much as possible of, I read (fav author: Nassim N. Taleb), write, run, lift, code (currently building an app), cook, make Youtube videos, turn books into Instagram accounts, grapple (BJJ), and travel (lived in NYC, Cape Town, Bali, Minsk, CMDX, Lima & Antalya so far). In December 2020 I married the most beautiful woman in the world. In January 2023, I became dad to the most beautiful baby girl. We currently live in Berlin, Germany.
