How airSlate grows

9 tactics and 13 figures from 1 interview.

airslate.com

airSlate is a group of document products, including pdfFiller, signNow and DocHub, each run by its own team with shared marketing, payments and devops. It grew mostly through search: millions of pages for the forms people look for, plus math-driven ad bidding, with pdfFiller's profits funding new products before outside money came in. The founder said both search edges are now fading with AI, and the group is betting on new AI products.

Summary written 2026-10-14 from the tactics below. Figures are as founders stated them.

airSlate's 9 tactics

pdfFiller · online PDF editor

4.8B keywords and 35M pages; the main source of a $106M product's traffic

Managed about 4.8 billion keywords with about 35 million pages, covering forms and documents SMBs search for. Worked with keyword clustering, a semantic core and discovery of new keywords; most keywords are unproductive, so the work is finding which clusters perform and covering as many of them as possible. The same customer-acquisition technology is shared across pdfFiller, signNow and DocHub.

pdfFiller · online PDF editor

Reached ~$18.5M before raising; ~$200M revenue on ~$150M raised

pdfFiller grew to about $18.5M in revenue before its first outside capital (2015). It was run as a cash machine whose profits were invested in other products. Guest's advice: raise as late as possible, don't pay yourself much, don't spend, preserve cash, and think about exit from day one.

Founder says 'so far, so good'; ~120 people per product

Acquired brands keep their names. A small set of common services (marketing, devops, payments) and the same customer-acquisition technology are shared; everything else is siloed, with each product having its own GM, development team, roadmap and tech stack. An AI Labs group builds common AI pieces, but products are not required to adopt in-house tech. Reasoning: the brand and top of funnel differentiate, not tech, and economy of scale no longer works with AI.

Acquisition targets must show product-market fit and domain expertise, and have more than ~$5M, ideally $10M, revenue so they make a significant contribution; $1M products are not interesting.

Because AI and search engines need well-structured information and the existing content is messy, the team is reducing what it published before and making the rest more productive. Guest's view: quality over quantity, and real sources like Wikipedia and Reddit will matter more than the number of landing pages.

bizdraft · B2B · AI legal agreement writer

Founder pleased with early traction; no numbers

Built bizdraft.com, an AI tool for SMBs that creates legal agreements, with an interface that combines editing and AI, using the lawyer-built forms as data. Not publicly announced; most likely will not be monetized and instead used as a traffic generation engine.

pdfFiller · online PDF editor

Founder credits it for early success; edge fading as everyone uses AI

Used high-level math for PPC bidding while competitors were unsophisticated. Guest says the edge is shrinking because everyone now has AI tools like Claude.

Plan to go from $200M to $400M: 20-30% growth from existing products, the majority from new AI products. Stay horizontal while verticalizing: the product morphs to the user segment (small medical office, pool contractor) and handles their documents, compliance and permits. No rush; wait for the feedback loop before scaling.

Didn't work; founder calls the guru playbooks 'bullshit'

Guest says he has tried the tactics gurus sell for influencing ChatGPT results and they do not work; models are getting smarter and unpredictable, so the answer is adaptability, product and reputation.
