log Sentinel
Bozidar Bojanoff, a senior software engineer with experience at Ericsson and TomTom, identified a critical gap in digital security: audit trails that even system administrators couldn't modify. The inspiration came from real-world incidents—during US elections, hackers would infiltrate networks and clear their tracks. log Sentinel was born to solve this problem by using blockchain technology to create immutable, tamper-proof logs of every action in a digital system.
Launched in 2017, the team built log Sentinel as a SaaS platform targeting B2B customers with diverse security and compliance needs. They developed a freemium model starting at €25-30/month for small startups, scaling up to custom enterprise pricing for banks and large organizations. The platform's value proposition was simple but powerful: complete audit trail integrity that no one—not even internal personnel—could compromise.
Starting from zero revenue, the team employed both inbound and outbound strategies. Remarkably, 50% of their early customers came inbound through organic search. People literally Googled for their exact solution, found log Sentinel, evaluated competitors, and chose them. The other half came through outbound sales and personal content marketing efforts. This organic interest validated the market need.
The SaaS model worked exceptionally well for finding customers—they achieved zero churn among their 20-customer base. However, Bozidar quickly realized that a $200/month average price point couldn't support the 3-6 month enterprise sales cycles required for B2B security software. "You can't make a six-month sales cycle work on a $200 per month price point," he acknowledged. This forced a strategic pivot: they began targeting larger enterprises with custom pricing based on log volume, and reconsidering their entire pricing architecture to focus on higher-value customers who could justify longer decision processes.
After a year, log Sentinel has grown to $4,000 MRR ($48,000 ARR) with 20 customers and $110,000 raised from private seed investors. With a team of 7 split between Bulgaria and Munich, they're increasing marketing budgets and rethinking their sales and pricing strategy. They already have contracts signed with major customers (including two banks) that will be paid upfront, positioning them for accelerated growth. The challenge ahead: scaling predictably while maintaining their zero-churn track record and shifting upmarket to customers who value immutability over price.
- •The founder's deep technical experience in security combined with direct observation of real-world breach incidents created a solution for a genuine, urgent market problem that customers actively searched for online.
- •Organic search captured 50% of early customers, proving strong product-market fit where prospects self-identified their need and chose log Sentinel over competitors through natural discovery.
- •The zero-churn customer base despite a low initial price point ($200/month average) demonstrated that the core value proposition—immutable audit trails—solved a critical compliance and security pain that justified long-term commitment.
- •A dual go-to-market approach combining inbound organic search with outbound personal content marketing and sales enabled customer acquisition before shifting to a higher-value enterprise model.
- 1.Identify a critical infrastructure or security gap by leveraging your own technical expertise in an industry where you've seen real-world failure cases, then validate that gap by checking search volume and competitor weakness for that specific problem.
- 2.Launch with a freemium or low-entry-price SaaS model ($25-30/month range) to rapidly acquire validation customers, then measure churn rate to confirm product-market fit before investing heavily in sales infrastructure.
- 3.Invest in SEO and content marketing around the exact problem statement customers search for, since organic inbound channels can deliver 40-50% of early customers with higher intent and lower acquisition cost than pure outbound.
- 4.After achieving initial traction, systematically shift pricing and sales strategy upmarket by analyzing which customer segments have zero churn and can support longer sales cycles, then target those segments with custom pricing based on usage or value metrics rather than flat fees.
