B2B growth has a missing middle.

For years the playbook was simple. Buy ads, chase rankings, fill the funnel. That worked when attention was cheap and buyers were patient. Neither is true now.

Ads and gated assets can create attention, but they rarely build trust on their own. Your buyer makes up their mind long before they ever talk to sales. They trust people. A logo does almost nothing on its own anymore. They trust the founder who taught them something useful, the newsletter they look forward to, the voice that shows up every week without asking for anything back.

That trust is the hardest part to build.

Getting noticed is hard. Keeping that attention through the long middle, while a stranger slowly decides you're worth betting on, is harder. That middle is where trust gets built, and it's the whole reason Pistachio exists.

I learned this growing audiences for other people. I took The Daily Aus from a standing start to 180,000 subscribers in ten months. I ran paid subscriptions at Mamamia from launch to 30,000. I led newsletter strategy for some of the biggest media brands in the world, launching the Australian newsletters for BuzzFeed, Tasty and LadBible. Media companies understand something most marketing teams miss. An audience is earned, then kept.

So that's what we build for B2B companies. An owned audience that compounds.

Founder content that finds the right buyers. A newsletter that keeps them close until they're ready. Every piece of it measured in real pipeline.

We keep the client list short on purpose, so you work directly with me and the people doing the work. And we run the same playbook on ourselves. Brand Chemistry is our own newsletter, with 120,000+ readers and open rates north of 50%. If it didn't work, you'd see it here first.

If you're tired of making noise and you want to build something that lasts, let's talk.

Isaac PeirisFounder, Pistachio
“I met Isaac when he was in charge of scaling the (now mighty) Daily Aus audience. He's my favourite sort of growth expert. One who can go micro, and knows how to optimize specific channels and test all the levers. But one who also thinks deeply about the macro, from key strategic needs to new commercial opportunities. Most importantly though, he's honest, hard-working and a pleasure to deal with.”
Seb NeylanHead of Growth, Up Bank
“Isaac understands the business of growth like very few people do. He'll help you craft your ideal strategy, then roll the sleeves up and build your systems, automations and whatever else is needed to make it happen. Isaac is an invaluable growth partner, super passionate and easy to work with.”
Tom AlderFounder, Strategy Breakdowns
“We were thrilled to have someone of Isaac's calibre work with us to come up with a solution that was as unexpected as it was revelatory. It has set us on a new path, and I couldn't be happier to recommend Isaac for anyone looking to grow.”
Ben HartFounder, Fireside Agency
“I followed Isaac on LinkedIn because I really loved his content, and was fortunate to then engage him to do a content audit across my channels and pull together a plan of attack. Isaac was not only easy to work with but he provided sound insight and feedback and met me where I was at. He spoke through different options and answered all my questions, which I feel has set me up for the next stage of growth with my business.”
Ben HamerFounder, ThinkerTank
“Isaac is such an awesome source of knowledge when it comes to all things growth. From newsletters to platform subscriptions and beyond – he has a knack for marrying up short term growth tactics to the bigger strategic picture. Bonus that he's also an all round nice guy.”
