B2B outbound · lead generation · custom software
Lead generation and cold email.And the software behind both.
Most outbound freelancers cannot build tooling. Most developers do not understand outbound. Pilot The Ecosystem does both: cold email infrastructure, qualified lead lists and custom software for B2B teams.
Campaigns and the tooling, from the same operator.
Cold email outreach & infrastructure
End-to-end campaign setup: domains, mailboxes, SPF, DKIM and DMARC, warm-up scheduling and multi-brand sending in German and English. Deliverability handled as an engineering problem.
Lead generation & list building
Decision-maker research with Apollo, Sales Navigator and Clay, plus custom-built scrapers. Lists qualified against your ICP, delivered in versioned rounds with your approval at each gate.
Data operations
Deduplication, umlaut and encoding repair, phone normalisation to E.164, gender classification for correct German salutations. Clean data before anything is sent.
Custom software development
Node.js, React and Python builds: web platforms, Chrome extensions and internal tools. One-time fee — you own the system instead of renting it.
Client-configured CRM
A live CRM and outreach platform, configured to your sales process: your pipeline stages, your terminology, your reporting. It already runs in production, so delivery takes weeks, not quarters.
AI automation
n8n, Make and custom-coded pipelines for reply classification, inbox triage at scale and internal workflows that replace subscription tools.
Live in production
A B2B outreach and CRM reporting platform for German-speaking sales teams, built and operated by Pilot The Ecosystem. It is the same platform configured for CRM clients.
- Google OAuth verification submitted to and approved by Google Trust & Safety.
- Production reliability engineering: durable save queue, automated backups, SQLite WAL mode.
- Virtual scrolling keeps large lead lists usable long past the point where spreadsheets stop being.

Two ways to work together
Hourly
For ongoing campaign management, reply handling and iterative work. Time tracked and reported.
Fixed price
For scoped builds: campaign setup, data projects, software and CRM configuration. Priced after a written specification.
There is no public price list. Every engagement is scoped on a call, and both models are available directly or through Upwork.
