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.

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.


Linkedin reminds me today its 10 year anniversary of SaaStock.

10 years since i took the leap to become a first time founder and creating an event and community business, something i’d never done before.

The first SaaStock was magical whilst it filled me with anxiety throughout.

Timing was everything. 

We’ve had tailwinds and faced headwinds.

10 years of growing the business, building a team, expanding internationally.

Showing up every day.

2 years during covid of trying to survive and providing value to our community when there was no in person. Never giving up.

Seeing some new products fail.

Seeing SaaStock Founder Membership (SFM) deliver value.

Working with amazing colleagues present and past.

10 years of looking forward to tomorrow on a Sunday night.

10 years of some exceptional memories and friendships forged.

It’s been hard. It can be exhausting. I’m getting some grey hairs (probs just age). I’ve put on weight, i’ve lost weight.

Yet the Why we do what we do. The purpose is so compelling and rewarding. I feel like I have the best job in the world (most days).

And whilst Linkedin says 10 years. It’s really day one again.

We’ve re-imagined SaaStock. A new program centred around 1:1 meetings and peer to peer learning.

It’s just the start of a new era at one of the most exciting times in B2B Software.

The fire is just as bright as it was 10 years ago.

Love to all our customers and SaaStockers over the years. I’m ready to build the future with you.

Running the largest 1:1 Meetings event in AI & SaaS

SaaS is dead!

Unless you’re actually building it.

Last night I sat at a table of SaaS founders where "dead" looked more like “doubling.”

One founder — fully bootstrapped — was at $8M ARR in April.
 Last night? $13M ARR.

Another I hadn’t seen in a year.
Now sitting at $16M ARR.

No outside capital.
No hype cycle.

Just leaning into tailwinds, building systems, and shipping value.

Add in founders at $5M ARR, $7M ARR — same story:
Quiet execution > loud predictions.

It’s funny — people keep declaring SaaS over.

Meanwhile, the builders I know are compounding.

There’s nothing better than breaking bread with founders who are doing the work.

We just closed our first ever 3-year deal.

10 years of SaaStock. Thousands of sponsors.
But never this.

Sure — we’ve always had loyal partners. Some have come back 7 or 8 years in a row, no questions asked.

But every time we tried to turn that into a multi-year commitment…
it ended up becoming “let’s just renew next year.”

So what changed?

The product changed. Not the pitch. Not the deck. The product.

Our Hosted Meetings program delivered more value — faster — than anything we’ve ever built.

Not for everyone. But for the ones it works for… it really works.

This customer ran 20 hosted meetings at SaaStock Europe last month.
They closed deals on site.
They got instant ROI.

And that’s why they just committed to:
 🔥 300 hosted meetings over the next 3 years
 🔥 at this year’s rate
 🔥 locked in

A 3-year deal wasn’t something we pushed.

It was something the results pulled into existence.

Product > persuasion.
Outcome > optimism.
Proof > promises.

On to the next one. 🙌

Look who's talking.

Or should I say speaking at SaaStock USA 2026, next April in Austin.

We've just published the first 10 speaker drop and I hope you like it as much as I do:

Manny Medina, Co-founder & CEO, Paid
Nathan Latka, Founder & CEO, Founderpath
Kady Srinivasan, CMO, You.com
Krish Ramineni, Co-founder & CEO, Fireflies.ai 
Adam Robinson, Founder & CEO, RB2B
Colin Nederkoorn, Founder & CEO, Customer.io
Jen Igartua, CEO Go Nimbly
Tanay Kothari, Co-founder & CEO, Wispr Flow
Richard White, Founder & CEO, Fathom
Anne Giviskos, SVP - Strategic Finance Leader & CAO, Navan

A mix of Unicorn Founders, $100M ARR companies, Bootstrappers and VC backed businesses. GTM & Finance leaders and dare I say influencers.

Something they all have in common? They are building the future of B2B Software.

I'm also a customer of 5 out of the 10, which had nothing to do with their selection.

Join me in the front row for their sessions at SaaStock USA in April, as well as Meetup our 1:1 meetings program and Tabletalks, our peer to peer learning program.

Save the dates, get your tickets, learn and meet with the best at SaaStock USA 2026.

Proud to be hunting Guideflow today on Product Hunt. 

I’ve been following their journey for two years, and watching friends build at this level of speed and ambition is something special. Their traction across SMBs and enterprise teams shows just how much the market needed a fresh take on interactive demos.

I’m celebrating the launch right from their office… in a duck outfit, their official mascot. Perfect timing to embody the energy they’re putting into this product.

Big day for the Guideflow team and it feels like only the beginning. 🚀
