B2B prospecting
like a
first appointment , not like a barrage.

Prospectra writes every cold email from your prospect's real context — their sector, their language, their moment in the cycle, your offer. One message at a time, handcrafted by a machine that takes its time. No spray-and-pray, no {{firstName}} variables that stay {{firstName}} in the recipient's inbox.

B2B prospecting has become a volume game that destroys trust.

A thousand identical emails, zero readers.

01 — Product

A complete prospecting suite, nota scattering of tools.

Prospects · campaigns · AI Wizard · classified inbox · GDPR audit · multi-domain. All in one console, accessible in five minutes, no installation.

02 — How it works

Three steps, five minutes, zero templates.

We don't ask for your card. We don't ask for your list. We show you the result first — with your real sector, your real language, your real signals.

01

You tell us

Five guided questions: your offer, your target, your tone, your market, your language. The Wizard listens, rephrases, adjusts — you don't type a single prompt.

02

The AI writes

A handcrafted prompt is generated, versioned, editable by hand if you want. Every email draws from the prospect's real context — not from a {{firstName}} variable.

03

You approve, we send

Demo mode to your own inbox first, no real email sent. When you're ready: switch to prod in one click, IMAP polling, auto-classification of replies.

03 — Architecture

The product, in six modules.

Six functions, one product, delivered together from the free plan onwards. No feature unlocked plan by plan — each module ships whole.

Contextual AI Wizard

Five guided questions, tailor-made brief by sector and language. No prompt to write. No leaking variables.

04 — AI Wizard

The Wizard.

Most tools hand you “50 templates that convert.” We write yours, with you, in five minutes. No prompt to memorize, no syntax to learn — the Wizard asks the questions that matter, you answer in plain English.

LIVE TRY · 1 CLICK

06 — Security & GDPR

Hosted in France, encrypted in transit and at rest.

No vague promise. Here's exactly what we encrypt, where we store it, and how we prove we're not cheating — audited code, public migrations.

GDPR & right to be forgotten

Prospect export in JSON, complete erasure via one API call, unique unsub token per recipient compliant with RFC 8058. 7-day grace window, forensic audit kept outside the tenant.

SHA-256 audit log

Every sensitive mutation appends a hashed link to the chain. Any alteration is detectable, exportable to the DPO in signed JSON. Retained 5 years.

One PG database per tenant

Isolation at the PostgreSQL engine layer — no shared schema, no shared row-level security. Physical separation between clients, guaranteed by migration.

AES-256-GCM encryption

API keys, SMTP/IMAP passwords and webhook secrets encrypted with a master key you keep at home. Sovereign hosting FR · Germany · Netherlands, never outside the EU.

  • SPF · DKIM · DMARC verified
  • Weekly encrypted backups
  • Sovereign hosting (FR · DE · NL)
  • No data outside the LLM call
07 — Manifesto

We built this product because we were fed up.

Fed up with receiving emails written by tools that don't know what a first appointment is. Fed up with {{firstName}} variables that stay {{firstName}} in the inbox. Fed up with follow-up sequences sent on Sunday night at 11:47 PM.

We wanted prospecting that writes like a human who has read the prospect's profile. That knows construction isn't addressed like SaaS, that German isn't translated word-for-word from English, that the first sentence matters more than the ten that follow.

We believe a cold email can be useful. That a salesperson who takes the time to write deserves a tool that takes the time to think. And that attention can scale — not just volume.
