Background

Katie Marrache is a Partner at JamJar Investments, the early-stage European consumer venture firm set up by the founders of innocent drinks. JamJar’s team page describes her background as “Ex innocent Commercial team” and says that before innocent she looked after James Caan’s consumer investments at Hamilton Bradshaw.

JamJar was launched after the innocent founders’ exit to Coca-Cola. The firm says innocent grew from a market stall to Europe’s number-one juice brand in 15 years with only £250k of investment, and that two days after the exit Richard Reed, Adam Balon and Jon Wright launched JamJar with Katie as their fourth partner to back the next generation of entrepreneurs.

At JamJar, Marrache sits on a partner group focused on early-stage European consumer brands. The firm’s stated model is to “love, help & invest in early-stage consumer brands,” backing companies early and supporting them with experience from building and scaling innocent.

Investment Thesis & Focus

  • JamJar’s stated thesis is: “We love, help & invest in early-stage consumer brands.”
  • The firm looks for three core traits: People: a complementary team that can “ruthlessly prioritise”; Product: a product consumers love with strong early metrics; Potential: high exit potential, specifically the ability to reach a £250m+ valuation.
  • JamJar’s explicit criteria are European companies raising £0.5m-£5m and capable of a £250m+ exit.
  • Sector focus is consumer-first: consumer brands, consumer technology, FMCG, beauty, wellness, personal care, pets, food and beverage, lifestyle, leisure, travel, and consumer software.
  • The firm’s portfolio and team biographies indicate a preference for brands with strong consumer pull, clear category positioning, and early evidence of repeatable demand.
