Ubruo, formerly BizzLead.13 years in lead gen.
I've built and been a partner in lead-gen companies since 2013. GTM strategy, in-house outreach systems, automation, and data for B2B teams, startup to enterprise.
Mladen Jankovic · Founder, Ubruo
The rename
Ubruo is the company that ran as BizzLead until 2026. Same founder, same operator team, same five-step system. The name changed with the move from bizzlead.io to ubruo.com in August 2026, and every case file now lives here.
The work
I started in the data trenches. At LeadGenius I shipped 4,000+ data samples for client pitches and helped land the firm's first enterprise client, eBay. On that pitch I handled every sample myself, and we won the bid against nine competitors.
Then came whole systems. At Northfield I ran cybersecurity campaigns, where enterprise data is hardest to find and verify. RSA and Red Hat, plus direct B2B into enterprise accounts.
In parallel, Radius: their main data provider since 2016. In one 6-month push I reached 600K real estate agents for them by SMS and email. Startup and SMB work at GrowthGenius, and sponsor acquisition for EU crypto events.
At Salesbox, 170+ campaigns across video, SaaS, HR, and consulting. Add GrowthGenius, Northfield, Sturm, and Ubruo (formerly BizzLead), and that's 320+ campaigns I've led.
Different verticals, same system. Define the ICP, find the buying signal, run the outreach, book the call.
