duwerk bringt Marketing-Know-how direkt in dein Unternehmen. Marketing fühlt sich manchmal an wie ein Knoten im Kopf. Zu viele Ideen, zu wenig Struktur, keine klare Antwort auf die Frage: „Wie bekomme ich mehr Leads?“ Für CMOs, die mit lauter Ideen nicht vom Fleck kommen. Für CEOs auf Sichtbarkeitsmission. Und für Marketer, die im Chaos aus To-dos, Tools und Trends nach einem Knotenlöser suchen. Zeit für duwerk. Mit Inbound-Marketing, SEO, Content-Strategie und CRM-Automatisierung – am liebsten mit HubSpot! Wir kommen aus der Praxis, haben Kampagnen gebaut, Funnels getestet und Leads von „Meh“ zu „Wuhu!“ verwandelt. Wir haben Marketing-Teams geführt und ihre Herausforderungen erlebt. Deshalb wissen wir, worauf es ankommt. Kurz gesagt: Wir sind die Co-Piloten, die du brauchst. Unser Werkzeugkasten: • Inbound-Marketing • Content-Strategie • Websites & SEO • CRM & HubSpot • Workshops & digitale Produkte Noch Fragen oder schon ganz viele Ideen? 👉 www.duwerk.de – Sag Hallo!

Revenue Circles ist Deutschlands Community für Revenue Leader und Account Executives im SaaS. SaaS hat sich verändert: engere Budgets, längere Sales Cycles, mehr Druck. Es gibt genug Events und Podcasts für Impulse. Was fehlt, ist ein geschützter Raum, in dem Revenue Leader offen über ihre echten Herausforderungen sprechen können. Genau dafür haben wir Revenue Circles gebaut. Das Format: kleine, exklusive Peer-Gruppen von 5 bis 8 Mitgliedern, zusammengestellt nach Zielsegment (SMB, Mid-Market, Enterprise). Einmal im Monat trifft sich die Runde vor Ort, begleitet von einem erfahrenen Growth Advisor. Dazu kommen themenspezifische Experten und ein fortlaufender Austausch in der Community. Kein Frontalvortrag, kein Networking-Bingo. Stattdessen: echtes Sparring unter Leuten, die ähnliche Probleme lösen. Vertraulich, verbindlich, konkurrenzfrei.

REP löst mit seinem einzigartigen SDR as a Service Ansatz das Vertriebsproblem zahlreicher Unternehmen. Für diese Unternehmen werden 5+ Herausforderungen gelöst: Fehlende Skalierbarkeit, mangelnde Geschwindigkeit, geringe Messbarkeit, fehlende interne Kapazität sowie mangelndes Know-How über neueste Trends und Technologien. Diese Herausforderungen treten insbesondere bei drei Zielgruppen auf: Zum Einen unterstützt REP Start-ups/Scale-ups, die eine Transition vom Founder-led Sales hin zu einer skalierbaren Vertriebsorganisation mit schnellem Wachstum bewältigen müssen. Die zweite Zielgruppe an die sich REP richtet ist der Deutsche Mittelstand. Einzigartige Produkte treffen häufig auf veraltete Vertriebsprozesse und Technologien. Zudem ist das Gewinnen von neuen Vertriebstalenten umso schwieriger. Mit REP führt der Mittelstand zahlreiche qualifizierte Neukundengespräche. Auch internationale Unternehmen, die den vertrieblichen Schritt in die DACH-Region wagen profitieren von REP. Neben dem komplexen Deutschen Arbeitsrecht werden diese Unternehmen zusätzlich von komplett verschiedenen Vertriebspraktiken als bspw. in den USA konfrontiert, was das Wachstum in den ersten Monaten häufig enorm verlangsamt.
