Pith turns the CSRD guidance, ESRS updates, and sector decarbonisation reading you do all day into a cited wiki per client — auto-tagged, always current, briefable before every meeting.
An ESG advisor lives in a field that rewrites itself constantly. CSRD timelines shift, ESRS guidance gets clarified, the EU Taxonomy moves, the LkSG and CSDDD raise the supply-chain bar, and an Omnibus simplification can rework an obligation you advised on last quarter. Each client sits in a different sector with a different materiality picture, and the reading that keeps you ahead — regulatory drafts, sector decarbonisation studies, greenwashing and PFAS risk notes — scatters across tabs, saved PDFs, and your memory the moment the deadline passes. Pith makes that reading a first-class knowledge layer. You bookmark while you read; Pith tags each save to the right client (auto), keeps a cited wiki per client current (auto), and assembles a briefing before each meeting (on demand) — every claim linked to the source it came from, so when guidance shifts you advise from a sourced page, not a half-remembered draft.
What changes for you
Scenario 1
Prep a double materiality assessment from your reading
Going into a client's double materiality workshop, you've spent weeks reading their sector's impacts, dependencies, and the relevant ESRS topical standards. Pith's per-client wiki already organises it by concept — material topics, value-chain exposure, the regulatory hooks — each claim cited back to the guidance or sector study it came from. You walk in with a sourced view of what's likely material for them, instead of rebuilding it from a folder of PDFs the night before.
Scenario 2
Track an Omnibus simplification against the original CSRD timeline
An Omnibus proposal reworks reporting scope and timing that you advised three clients on under the original CSRD rules. As you read the proposal, the Council position, and the first commentary, you bookmark each to the affected clients. Pith's source-conflict detection flags where the new guidance contradicts what's already in the wiki — so when a client asks "are we still in scope, and from when," you answer from a page that shows both the original obligation and what changed, every claim cited.
Scenario 3
Onboard onto a new client's sector in an afternoon
You take on a chemicals manufacturer with PFAS and supply-chain due-diligence exposure you haven't advised on before. You start reading into the sector — LkSG obligations, CSDDD transposition, the decarbonisation pathway — and the wiki builds as you go. A few days in you have a cited page on their material risks, the applicable frameworks, and the open questions, organised by concept rather than buried in links. Getting current on a sector compresses from weeks to an afternoon.
Founder's note
I'm a consultant, not a sustainability specialist, but I built Pith for exactly this kind of work: reading at volume in a field that won't sit still, and never being able to find — or source — what I'd read when the client meeting was tomorrow. ESG advisory is the sharpest version of the problem I had — the regulation moves under you, every client needs a different slice of it, and your advice has to be defensible back to the guidance. So I built the layer that keeps your reading cited, scoped per client, and ready when the landscape shifts.
FAQ
How does Pith handle client confidentiality and EU data residency?
Bookmarks and wiki pages are workspace-scoped to your practice and client-tagged to the right engagement, isolated at the database level. Data lives in Frankfurt, Germany — EU-only residency, GDPR-aligned, with full export anytime as Markdown or JSON. We do not train models on your content. Apply your firm's policy on what you save; Pith treats every save as private to your workspace.
How is this different from a Notion workspace per client?
Notion makes you author and maintain the page — a curation tax that gets skipped when three clients' CSRD deadlines collide. Pith builds the per-client wiki from the regulatory and sector reading you already do, auto-tagged and cited, and keeps it current automatically. For a constant reader in a field that changes weekly, that's the difference between hours of authoring and zero.
Does it work for a solo advisor, or only a firm?
Both. A solo advisor runs a personal workspace with one tag per client; a firm shares a workspace where the team sees the same cited per-client wikis, scoped per engagement. The same model fits an Einzelberater and a sustainability practice.
What happens when the regulation changes — does the wiki go stale?
That's the case Pith is built for. You keep reading; new saves flow into the right client's wiki automatically, and source-conflict detection flags where fresh guidance contradicts what's already there — like an Omnibus simplification against the original CSRD timeline. You see both, cited, and update your advice from a page that shows what changed rather than reconstructing it from memory.
Can I share a wiki page or briefing with the client?
Yes — signed-URL shares with time bounds and revocation. The client sees a read-only version of the wiki page or briefing, every claim still linked to its source, without access to your workspace.
