pdfFiller is a Boston-based document management platform founded in 2008 by Vadim Yasinovsky as a lifestyle business. The company enables end-to-end digital document workflows, including form creation, fillable fields, e-signatures, mail merge, and API integrations for CRM and ERP systems. By February 2017, the platform had grown to approximately 200,000 paying customers and roughly $24 million in annual revenue, all without raising outside capital.
Borya Shakhnovich, co-founder and president, joined at the end of 2011 and applied a sophisticated digital marketing engine to accelerate growth. The company runs approximately 60 million keywords across SEO and Google AdWords, generating about 4 million monthly website visitors, and acquires customers at a cost of less than $10 each while collecting roughly $10 per month in average revenue per user. With zero salespeople as of early 2017, all revenue is generated through no-touch, self-serve channels.
The company later rebranded and expanded under the airSlate umbrella, raising $51 million in 2022 at a $1.25 billion valuation and reporting $100 million in annual revenue that same year. By 2026, the broader airSlate platform had grown to six products, more than 860,000 customers, a team of 650 employees, and approximately $200 million in annual revenue across multiple product lines.
