About · Quelvo

The Notion portal layer
your clients actually need.

You use Notion to run your business. Your clients need access to specific parts of it. Quelvo is the minimal, secure bridge between the two.

The problem

Notion wasn't designed for external clients.

Notion is a phenomenal workspace tool. But the moment you need a client or stakeholder to see a slice of it, you hit a wall. Guest seats are blunt instruments. Exports go stale. Building custom software is overkill.

Without Quelvo

  • Share the Notion page — client sees your entire sidebar
  • Export to PDF — information is stale immediately
  • Build a custom app — weeks of work for a table view
  • Give client a guest seat — they see everything

With Quelvo

  • Client visits their branded portal — sees only their data
  • Data is live from Notion — always current
  • No engineering required — set up in minutes
  • Granular per-client access control from your dashboard

Why we built this

Born from a real frustration.

Quelvo started from a simple recurring problem: agencies and freelancers build their entire workflow in Notion, then scramble every time a client asks “can I see where things stand?”

The workarounds are painful. Share the Notion page and clients see your entire workspace. Export to a document and it’s stale within hours. Build a custom portal and you’ve just signed up for months of maintenance.

There was clearly a missing layer — something that lived between your private Notion workspace and your clients’ browsers, that was secure, brandable, and required zero ongoing technical effort.

That’s Quelvo. We built the tool we wish we had.

How we think

Principles we don't compromise on.

Subtract, don't add

Every feature we ship has a reason to exist. We say no far more often than we say yes. Less interface is more clarity for your clients.

Private by default

Clients see exactly what you choose and nothing more. Access control is applied server-side on every request — there is no client-facing override.

Notion stays the source of truth

We don't copy your data into a separate system. Quelvo is a read layer. Your Notion databases remain canonical — always.

Fast by necessity

Magic-link login, instant portal access, 60-second caching. Client portals that feel slow are portals clients stop using.

Under the hood

Security is structural, not cosmetic.

We made deliberate architecture decisions that make Quelvo safe by design, not by policy.

Notion tokensAES-256-GCM encrypted at rest · never transmitted to clients
Client sessionsHTTP-only JWT cookies · scoped per portal · 24h expiry
Magic links15-minute TTL · single-use · rate-limited (3 / email / 10 min)
Data accessOwner-configured filters applied server-side on every Notion query
Caching60s Redis TTL · no stale data longer than one minute

Give your clients the portal they deserve.

Set up your first portal in minutes. No engineering required.
