About ScaleRush

ScaleRush is a Sofia-based B2B lead generation agency focused on outbound prospect research and appointment setting. Founded by Boyan Vasilev, the firm markets a HADI-style hypothesize-act-data-iterate outbound protocol for consulting, SaaS, and IT companies that need repeatable pipeline instead of generic email blasts.

Who ScaleRush Is Best For

ScaleRush is best for B2B service and software teams that have outgrown referral-only growth and want a tested outbound system. The official site emphasizes prospect research, deliverability-first campaigns, and handing over qualified meetings rather than vanity open rates.

Why Choose ScaleRush

Official positioning is pure B2B lead generation and appointment setting

Publishes a structured outbound testing framework rather than template spam

Clutch recognition as a top lead generation and sales outsourcing company in Bulgaria

Strong public emphasis on deliverability and qualified meetings

Things to Consider

Boutique Bulgaria-based team may not match multi-continent phone-first SDR RFPs

Best fit is B2B services and SaaS; consumer brands are outside the core motion

Public case volume is still maturing versus larger global outbound firms

Buyers wanting only inbound content or SEO should look elsewhere
