Senior Marketing Manager in London

PANTA is seeking a highly hands-on Senior Marketing Manager to own and execute the company’s end-to-end marketing strategy as we scale the company. This is a pivotal role for someone who thrives in early-stage environments, combines strategic brand thinking with strong execution, and is equally comfortable shaping positioning as they are running campaigns and analysing results.

The successful candidate will take full ownership of brand, messaging, demand generation, and go-to-market execution, acting as the internal marketing “owner” and a close partner to the CEO, product, and commercial teams.

About PANTA: PANTA is revolutionising the $25 trillion index investing landscape through our innovative Index Operating System. Founded by index industry veterans, we're bringing modern Index technology infrastructure to an industry ripe for transformation. Our platform enables index providers, asset managers, banks and financial institutions to create, test, and manage indices with unprecedented efficiency and flexibility.

The Role - Key Responsibilities:

• Own and execute PANTA’s end-to-end marketing strategy across brand, demand generation, and go-to-market.
• Develop and refine PANTA’s brand positioning, narrative, and messaging across all channels.
• Translate product capabilities into clear, compelling value propositions for institutional and enterprise audiences.
• Design and run lead generation programmes across digital channels (content, paid, events, partnerships).
• Own website, marketing materials, sales collateral, presentations, and thought-leadership content.
• Build and manage content strategy including articles, whitepapers, case studies, and announcements.
• Work closely with product and sales to support pipeline development and commercial traction.
• Set up and track marketing KPIs, funnels, and attribution across channels.
• Manage external agencies, designers, PR, and freelancers where required.
• Support strategic initiatives such as fundraising, partnerships, and major product launches.
• Continuously test, iterate, and improve marketing effectiveness with a data-driven mindset.

Required Skills & Experience:

• Proven track record in both brand building and lead generation.
• Strong ability to create clear messaging for complex, technical, or data-driven products.
• Hands-on experience running campaigns end-to-end (not just managing agencies).
• Excellent written communication skills, with experience producing high-quality content.
• Strong understanding of digital marketing channels and performance measurement.
• Ability to operate independently, prioritise effectively, and execute with limited resources.
• Comfortable working in a fast-moving startup or scale-up environment.

• Experience marketing to institutional investors, asset managers, or enterprise financial clients.
• Background in index infrastructure, market data, analytics or fintech platforms.
• Experience supporting go-to-market for early-stage or growth-stage products.
• Familiarity with CRM and marketing automation tools.
• Experience supporting fundraising or investor communications from a marketing perspective.

What We Offer:

• A central, highly visible role shaping the external perception and growth of a category-defining fintech.
• Direct impact on commercial traction, brand credibility, and company growth.
