Episode 4: Abigail Smith and James Clench (Harpswood) - Demystifying PR for Climate Founders

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

Abigail Smith and James Clench, co-founders of Harpswood PR, share practical lessons on getting media coverage for climate tech startups on Episode 4 of Scaling Green Tech, a podcast by Adopter. Harpswood works with purpose-driven businesses from seed stage through to established companies, with clients including Octopus Energy, Naked Energy, and Open Climate Fix.

Clench spent 15 years at The Sun as reporter and head of news before moving into PR. Smith built her career across PHA and global agency MSL before the two co-founded Harpswood in 2020. Between them, they bring both sides of the journalist-PR relationship to the conversation. The episode covers when to start investing in PR, how to frame a story journalists will actually cover, what kills a press release before it gets read, and why third-party media coverage matters more than most founders realise - particularly when investors are running their due diligence Google searches.

This episode is relevant for climate tech founders approaching seed and Series A, communications leads at early-stage deep tech companies, and anyone trying to make sense of what journalists actually want.

Key Takeaways

  • Journalists will read the headline and possibly the first line of a press release. Clench cites the journalism school rule: a press release intro should be no longer than 30 words.
  • Inconsistent messaging is one of the first things Harpswood tests with new clients. Ask two co-founders to describe their business separately - they will often give completely different answers.
  • One or two well-placed statistics land better than a long list. If someone on the Today programme delivers seven or eight stats in a row, even an attentive listener gets lost.
  • Founders tend to repeat their key message far less than they should. By the time you are sick of saying it, most of your audience has only heard it once.
  • Investors use quick Google searches as part of due diligence. A company that has deliberately avoided PR can find investors asking: why have I not heard of you?
  • Personal angles get more coverage than business angles. A pitch leading with "my business has no HR department" outperformed any pitch about Octopus Energy's product or growth.
  • Strong images consistently determine whether a story gets picked up and where it is placed. An eye-catching photo in the right location will often do more than the press release.
  • Harpswood's banned word list includes: utilise, leverage, reach out, circling back, and going forward. Smith and Clench argue these signal corporate register and cause journalists to disengage immediately.
  • Philip Collins, who wrote speeches for Tony Blair, identifies three things that produce clarity in writing: simplicity, precision, and brevity. Clench applies these directly to press releases and client messaging

FAQs

  1. When should a climate tech startup start investing in PR? 

Clench and Smith suggest pre-seed companies are typically better served by DIY PR, since they may not yet have a deliverable product or service. Between seed and Series A is the point they most commonly see companies making the transition. Smith adds a case for starting earlier: investors run Google searches before they take a meeting, and a company with no media presence raises questions. Earlier-stage companies also have more freedom to express strong opinions - that flexibility narrows as investor scrutiny increases.

  1. Why does media coverage matter to investors? 

PR provides what Clench and Smith call third-party validation - credibility that comes from an independent journalist scrutinising your product or service and writing positively about it. An investor reading a piece in TechCrunch, Sifted, or Bloomberg gets a signal they cannot get from your own website. Clench's framing: it is what is being said about you after you have left the room.

  1. What do journalists actually want from climate tech founders? 

Journalists want a story, not a briefing about your business. The job of PR, according to Clench, is to find the intersecting set between what the journalist wants and what the client needs to say. That often means leading with a different angle than the one the founder wants to push - the human story, the unusual fact, the news hook - and landing the core message further down.

  1. What is the inverted triangle and how does it apply to press releases? 

The inverted triangle is a journalism convention: the most important information goes at the top, with supporting detail following in descending order of significance. Clench describes the most common press release mistake as the "delayed drop intro" - scene-setting for several paragraphs before arriving at the actual point. By the time the point appears, the journalist has already moved on.

  1. What words and phrases should founders avoid in press materials? 

Harpswood's banned word list includes utilise (use "use"), leverage (unless referring specifically to financial leverage), reach out, circling back, strategic partnerships, and going forward. The issue is not those words specifically - it is what they signal. When a journalist sees that register, Smith says, they already know the release is not going to be worth their time. Tom Fletcher, formerly Britain's youngest ambassador, and Michael Lee, who wrote speeches for the Bill and Melinda Gates Foundation, both independently gave Clench the same advice: avoid jargon and acronyms above everything else.

  1. How do you write a subject line that gets opened? 

Smith argues the subject line is often the only thing a journalist reads. What works is specificity and personality rather than description. A pitch for Greg Jackson's Desert Island Discs appearance used the subject line "heat pumps to heavy metal." A pitch for Sustainable Ventures at the former GLC headquarters at County Hall used "Red Ken to Green Den." A team member who referenced George Orwell in a subject line - matching a journalist's known reading - secured an FT feature. The common thread is doing enough research on the journalist to know what will make them curious.
