The challenge

Seven Senders had product-market fit, a closing team that could close, and a Salesforce holding roughly 20,000 company accounts and 30,000 contacts. What it didn't have was a system to surface buying signals, prevent re-contacting unsubscribed leads, detect when known contacts changed jobs, or distinguish "this account is in active conversation" from "this account hasn't heard from us in 8 months and is fair game again." Outbound was constrained because the underlying data layer was constrained.

What Scalantec built

Scalantec functions as Seven Senders' embedded Outbound + RevOps department. Senior GTM engineers work week-to-week inside Seven Senders' Salesforce, building infrastructure across four layers:

• Data layer. Last-customer-reply tracking. Free-for-outreach auto-flip logic that respects customer status, open opportunities, and recent activity. Duplicate prevention on every account and contact upload. Master Inbox routing that captures forwarded and out-of-office replies that previously went lost.

• Reply classification. Every inbound reply is automatically categorized into a multi-state taxonomy that drives downstream automation. A booked meeting auto-pauses outreach to colleagues at the same account. A do-not-contact response permanently blocks. An out-of-office retries later. A "wrong person" surfaces a referral while keeping the account live.

• Intelligence layer. AI-generated account summaries refreshed on every new task. Job-change detection on every contact, with notifications routed to account owners. Multi-signal lead scoring driven by website traffic, hiring patterns, news, and fundraising signals. Auto-creation of accounts and contacts from a website URL or LinkedIn profile.

• Execution layer. Country-proximity, vertical, and competitor outbound campaigns across email and LinkedIn, with deliverability discipline that holds bounces below 2%.

When a contact changes jobs, a task fires. When an account raises money, a signal hits a sequence. When a positive reply lands, it auto-routes, classifies, and pauses outreach to colleagues at the same account. The Salesforce is no longer a passive database. It is an active engine.
