Vadim Yasinovsky, co-founder of pdfFiller and CEO of airSlate (parent of pdfFiller, signNow, DocHub, US Legal Forms, airSlate Flow), breaks down how a plain-looking PDF editor page became a $106M/year product with 866,000 paying customers — inside a company doing $200M in revenue across 1.1 million customers at an average of $180/year.
He raised just $150M total (last round: $52M at a $1.25B valuation in June 2022) and now says the company is optimistically worth $800M — despite doubling revenue since. He bought signNow at $3M and grew it to $35M. He built an SEO machine on 4.8 billion keywords and 35 million pages, and now says that playbook is dead within 9–12 months as ChatGPT and AI search take over.
In this episode:
- Why 650 employees are split into siloed 120-person product teams with no shared tech
- Why airSlate didn't become Harvey despite 85,000 lawyer-built legal forms as a training set
- Why Vadim says the "ChatGPT SEO" gurus are "b.s." and his influence on search drops from 80% to 30%
- His unannounced AI product (bizdraft.com) and why he won't monetize it
- The path from $200M to $400M: 20–30% from existing products, the rest from vertical AI
- His M&A filter: product-market fit, domain expertise, $5–10M+ revenue minimum
- His advice to founders: raise as late as you can, cash is king, preserve it now
