Jakob Ustarbowski
Interim Head of Marketing — for B2B and regulated markets
Good software doesn't sell itself. Jakob Ustarbowski steps in as interim Head of Marketing exactly where marketing has lost its lead — or where it consists of five tools that don't talk to each other. Instead of isolated campaigns he builds a system: website and landing page architecture, user journeys through to the qualified lead, CRM and marketing automation with HubSpot, email sequences, webinars, and tracking that reports all the way down to contribution margin.
He has worked in the digital economy since 2010 — around Rocket Internet, Delivery Hero, Finleap and Goodgame Studios, as well as in the pharmaceutical industry. As Head of Online Marketing he ran an annual budget of €11m across three markets and halved cost per lead; in a strictly regulated pharma setting he built up a four-figure audience of verified physicians over four years.
What I value about his approach: the engagement is time-boxed from day one. Analysis, build, handover — after four to six months the system stands, it's documented, and it keeps running without him. That's the same attitude I hold in software development. If you need to build marketing in B2B or a regulated market and don't want a grab bag of channels, Jakob is the right call.
Roofora
I'm happy to recommend partners whose approach I share — and at Roofora, privacy comes first. Roofora is a marketplace for photovoltaic offers where vetted solar installers and tradespeople bid transparently for your project and undercut one another, so you get the best possible price.
What sets it apart: your request stays anonymous. You sign up without an email address or phone number and decide yourself whether and when you want to be contacted at all. Only once you actively approve a specific installer are your details shared — no cold calls, no sales pressure, no flood of phone calls.
If you're planning a solar installation and value both privacy and genuine price competition, Roofora is well worth a look.
