A PTHR venture
ARC — A Regenerative Culture.
Accelerating sustainable value creation. ARC helps organisations demystify ESG, B Corp, Net Zero and circularity — turning sustainability from a compliance burden into a genuine business imperative and a source of meaning for your people.
Three ways ARC works
ARC to you
Weekly advisory for founders and sustainability leads — a trusted sounding board as you build your ESG story.
ARC to your team
Workshops and co-creation sessions to build carbon literacy, shape strategy and mobilise the whole organisation.
ARC to AI
Verifying and refining AI-drafted ESG, B Corp and Net Zero work so it's rigorous, credible and truly yours.
Principles
- Sustainability is a business imperative — and a moral obligation.
- Purpose-led business outperforms — meaning and margin aren't opposites.
- Co-create, don't consult at — the answers live inside your organisation.
- Pragmatism with rigour — credible, evidence-based, achievable.
- Carbon literacy for all — every role can contribute.
Cadence
Inform & ignite · co-create & commit · enable & energise.
Typical challenges ARC helps with
- We want to start our B Corp journey but don't know where to begin.
- Our ESG story feels vague — it needs sharpening.
- We're serious about Net Zero but lack the internal expertise.
- We want our team to be carbon-literate and confident.
- We need someone to sanity-check our sustainability strategy.
The ARC team
Led by Kirsten Buck (Founder), with Catalina Ticau (B Leader), Eva Morales and Corina Radu. ARC is a venture within PTHR — legally part of the group, operationally its own thing — so you get the depth of a specialist team with the backing of a 14-year-old B Corp consultancy.
