Sondero is an AI operating system for mid-market companies. Three agents (Email Assistant, Meeting Prep, Prospect Intelligence) run inside the tools your team already uses, so they spend less time on admin and more on revenue.

Decision-makers and revenue leaders in mid-market companies in the DACH region (Germany, Austria, Switzerland) who want their teams to spend more time on conversations and deals, less on research and inbox triage.

Where is my data processed?

On German servers, with zero retention. No US routing. Data is processed and deleted after delivery — never used for training.

What integrations do you support?

Sondero connects to Google Workspace, Outlook, Notion, ChatGPT, Claude, Gemini, HubSpot, Slack, LinkedIn, Asana, and ClickUp. No new tools, no migration, no retraining.

Is Sondero compliance-ready?

Yes. AVV template, full GDPR documentation, and EU data residency are ready to sign on day one. No 3-month legal back-and-forth.

Who is behind Sondero?

Sondero is built by Christoph Ebhart (20+ years B2B revenue leadership) and Kail (AI implementation and design). Operated by Cediro Consulting GmbH, Austria. The team operates from Berlin.

When can I use Sondero?

Sondero is pre-launch. First-wave access opens spring 2026. Join the waitlist at https://sondero.ai/get-started for early access and the launch invitation.

Is Sondero a SaaS I install?

No. Sondero is built and operated for you — we install the agents into your existing stack and run them. Your team uses the AI without changing how they work.

Step by Step

Scroll horizontally. Each step shows what the engine actually does at that moment.

Step 1

Sync All Contacts

Forms, outbound tools, events and apps land in HubSpot or Attio. n8n covers the gaps. The record is finally complete.

Step 2

Clean Records

ZeroBounce or Kickbox validate emails. Twilio Lookup validates phones. Stale records flagged, duplicates merged.

Step 3

Enrich Records

Clay, Clearbit, Apollo, PDL, Crunchbase fill in firmographics, technographics, funding stage and headcount.

Step 4

Lead Intelligence

News, funding, launches and hiring trends pulled in continuously via n8n. The context lives on the record.

Step 5

Score & Segment

Every lead scored 1–10 via Clay plus AI. Segments built on the combined signal of fit and intent.

Step 6

Choose Playbook

Each segment maps to a clear action plan in HubSpot or Attio workflows. The next step is never improvised.

Step 7

Revive Closed Lost

Deals lost months ago re-open when signals change: new VP, competitor switch, funding round. Pipeline returns.

Step 8

Champions Change Jobs

Past champions tracked across job moves via Sales Navigator. They land somewhere new, outreach triggers automatically.

Step 9

Reactivate Ex-Clients

Churned customers with fixable reasons get queued. Some come back. Many provide referrals on the way.

Step 10

Trigger Actions

Sequences start, tasks assign, alerts fire. The execution layer does not wait on a human to remember.

Step 11

Update Fields

Scores, stages, owners and properties stay current in HubSpot or Attio. The CRM reflects reality, not last quarter's.
