What Sisters Inc. does

Sisters Inc. (legal entity: Sisters & Company Oy) is a Finnish B2B event and experiential marketing agency founded in 2004 and headquartered in Espoo, Finland. The company plans and produces corporate events, brand experiences, employee events, trade show stands, and hybrid and virtual events for large and mid-sized enterprises, with a stated portfolio of over 2,500 completed projects and an NPS of 92-97. Its service portfolio spans concept development, project management, creative direction, graphic design, photography, video production, and end-to-end event management, delivered by a team of approximately 23 staff the company brands as 'Happiness Designers.'

The firm operates no proprietary technology platform or software product; revenue is generated entirely through professional services on a project-based, quote-priced model. Its named customer base spans more than a dozen verticals — including Fujitsu, Deloitte, Fortum, Elisa, Stockmann, Oriflame, POP Pankki, Mehiläinen, PwC, Sanoma Media, Hedengren, NRC Group, and Technology Industries of Finland — served primarily through a direct enterprise sales motion with personalized outreach, free strategy sessions, and quote requests. Geographic operations are centered on the Nordics (primarily Finland) with selective international deliveries, including a Fortum trade fair stand at E-world 2026 in Essen, Germany.

In late 2025 and early 2026 the founder-led family business installed an external CEO (Miika Lumme) and COO (Juho Hiidenmaa) to professionalize operations amid a period of record revenue growth. The company also operates a wholly-owned B2C consumer activation sub-brand, Brothers & Co., holds an Ekokompassi (ISO 14001-based) environmental certification, and produces the Sisters Talk podcast for thought-leadership marketing. There are no disclosed funding rounds, institutional investors, or parent company relationships; the business is self-funded and founder-controlled.
