Engineering as marketing (free tool lead gen)
Build a free, useful micro-tool (calculator, generator, diagnostic) related to your product's problem space to attract high-intent organic traffic and convert it into leads.
Why this can grow a startup
Free tools solve a real, immediate problem, which builds trust before any sales conversation. They attract high-intent organic search traffic from people actively looking for solutions. Unlike content marketing, tools provide ongoing utility that keeps users returning. Each tool becomes a permanent SEO asset that compounds over time, and the users who find value in the free tool are naturally pre-qualified for the paid product.
Company example
BitByte Technology and Prospeo's 2026 growth guide both document this as a top strategy for low-budget startups, noting that a single free tool often generates more leads than $10,000/month in ad spend; a B2B SaaS company replaced a gated whitepaper with a 3-minute diagnostic quiz and saw 40% more leads with double the sales-qualified rate.

Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
