About
Sini Teikari is a growth and business development leader with a background spanning finance, enterprise technology, commercial leadership, strategic partnerships and private-market relationships.
Sini began in financial services, building a foundation in finance, client relationships and commercial thinking that still shapes how she reads a business.
She then spent more than six years at SAP across enterprise sales, demand generation, go-to-market, regional commercial planning, innovation, digital transformation, AI and modern practice adoption, change management and strategic initiatives, working across the Nordics, Baltics, EMEA and global teams.
From there she moved into commercial and growth leadership, building and leading functions across sales, partnerships, GTM, revenue operations and team development — most recently as Chief Growth Officer at Fit+, one of the businesses built through Heysi Ventures.
Her advisory work spans consumer brands and CPG, including US market entry, distribution and commercial acceleration; entertainment and live experience, including events, sports, talent, artists and broadcasting-related opportunities; luxury and hospitality, including premium experiences and UHNW environments; and private markets and alternative assets, including strategic financing discussions, art and asset monetisation and commodities.
Heysi is the platform through which that work is conducted today: independent, senior and built around growth strategy, commercial development, strategic partnerships, international expansion and private-market relationships.

Sales · Demand Generation · Innovation & Change · Strategic Initiatives
Built my commercial and leadership foundation at SAP over six years. As sole Account Executive for the Finnish midmarket (€0–300M revenue companies), I owned the full sales cycle across that market — then moved into owning demand generation strategy and GTM execution for the Nordics & Baltics as Demand Manager, aligning Sales, Marketing and Channel around a single regional strategy. From 2022, I led Innovation and Change for EMEA North — strategic projects on AI adoption, business growth and organisational change — while also selected for SAP's global DXP Strategic Initiatives, bridging global digital sales strategy with regional execution. Across six years, I moved from owning an entire national market as an individual contributor to regional and global leadership within a complex enterprise environment.

Today, Sini works with founders, leadership teams, investors and growth businesses where commercial strategy, partnerships, market access or senior execution need to come together.
The work can mean advising from the outside, stepping into a leadership role, building a commercial function or opening the right strategic relationships — depending on what the business actually needs.
Credibility
Work at the intersection of large enterprise environments, high-growth companies, founders, investors, partnerships and international expansion.
Positioning
A senior commercial and strategic advisor who can move between functions and bring the right relationships into the problem when useful.
This combination is the reason the Heysi model works.

Based in Helsinki, working across Europe, the United States, Latin America, MENA and the wider EMEA region.
Network

The network is not a directory. It is activated selectively around the problem, and no relationship is presented as available to every client.
