Episode 1: 5 Website Mistakes of Green-tech Startups

Logo of Adopter - the marketing agency for deep tech and climate adaptation.

Episode summary

Matt Jaworski, co-founder of Adopter, discusses the five most common website mistakes made by early-stage and scaling green technology companies on Episode 2 of Scaling Green Tech, a podcast by Adopter.

Jaworski's core argument is that a website functions as the first due diligence step for investors, partners, and customers - and that neglecting it is a business decision with real commercial consequences. He traces how this plays out across five specific failure modes: a missing or outdated site that loses a warm investor introduction before it begins; aspirational mission copy that fails to answer what the company actually does; vendor lock-in that leaves founders paying for five-minute updates; unscalable platforms that require rebuilding every few years; and the use of stock or AI-generated images where real laboratory and facility photography is expected. A Gartner report found that over 60% of B2B buyers visit a company website before their first meeting.

This episode is relevant for green technology founders preparing for investor outreach, early-stage deep tech companies building or rebuilding their first website, and programme managers at venture builders who support portfolio companies on go-to-market readiness.

Key takeaways

  • Over 60% of B2B buyers visit a company's website before their first meeting, according to a Gartner report pre-pandemic - a proportion Jaworski and Keddie expect has grown since.
  • A venture builder programme manager described an investor declining to respond to a warm startup introduction because the company's website showed nothing relevant. The investor crossed the company out based on the website alone, before any conversation took place.
  • Failing to maintain a website is still a marketing choice. Companies that go without one signal to investors and partners that they are not operational or ready to commercialise.
  • Mission statements such as "we make the world a better place" or "we make this industry more sustainable" do not answer the questions investors and customers need answered: what do you do, who do you do it for?
  • The "caveman test" in website design asks whether a first-time visitor can understand the core offering without prior knowledge of the company or sector.
  • Vendor lock-in occurs when a website is built in a way that only its original developer can edit, leaving founders unable to make routine content changes without paying for each one.
  • AI-generated and stock images on a green tech website create credibility risk. Investors and partners expect photography of real laboratories, facilities, and operations.
  • Stanford University's persuasive technology lab has published Stanford Guidelines for Web Credibility covering case studies, testimonials, and other traction signals relevant to early-stage companies.
