About
A sales function you can hire, rather than build.
HEYSI Revenue exists because the gap between a good product and predictable revenue is almost always commercial infrastructure — not effort, and not ambition.
Three parties, one operating layer.
Companies have products that deserve more commercial attention than they get. Experienced sales professionals want good products to sell without inheriting somebody's unfinished sales department. HEYSI is the layer between them.
We select the products, design the commercial model, build the infrastructure, recruit and match the sellers, train them, and manage performance, CRM, reporting, commission administration and handovers.

Founder
Sini Teikari
Sini Teikari built the commercial model and the leadership foundation behind HEYSI Revenue, drawing on enterprise sales, commercial leadership, go-to-market and growth, partnerships and team building.
The business comes directly from that work: repeatedly meeting companies with strong products, real customers and no realistic path to building the sales function the product deserved.
HEYSI Revenue is a standalone commercial business. It shares the HEYSI name and standards with HEYSI Advisory, which operates separately in advisory work.

How we operate
Four principles.
Honest commercial assessment
We say no to products we do not believe can be sold well externally. A declined engagement costs less than a failed one.
Seller-first network
Sellers are given products they can genuinely sell, with the materials, training and support to sell them properly.
System before people
The playbook, CRM, qualification criteria and messaging exist before anyone contacts a buyer.
No invented credibility
No borrowed logos, invented case studies or fabricated statistics. What is written here is what exists.
How this is structured
Four structural choices.
The system comes first
We don't introduce a salesperson and hope they figure it out. The playbook, materials, CRM and qualification criteria exist before anyone sells.
Matched, not random
Products are matched with sales professionals on real commercial fit: sector, buyer access, geography, language, deal size and sales style.
Operated, not handed off
HEYSI stays inside the sales infrastructure, the pipeline and the performance management for as long as the engagement runs.
Aligned to results
The commercial model combines a fixed operating layer with performance-based economics, and the balance between them is a choice you make.
Two ways in.
Companies apply to build a sales channel. Sales professionals apply to join the network.
