CampaignStack is campaign orchestration for B2B lead generation agencies running outbound at volume across LinkedIn and email.

The design starts from the constraint everyone else ignores: a client's LinkedIn account is not replaceable. So every connected account gets a hard daily action budget that ramps up over weeks instead of firing at full volume on day one, a dedicated residential proxy, and a persistent browser fingerprint that stays stable between sessions. The numbers are visible in the dashboard, not buried in a settings page.

AI drafts the messages. A human approves them in a review queue before anything leaves the account, and auto-send stays off until you switch it on.

Underneath, leads are scored against your ICPs, signals like job changes and post engagement decide who is worth contacting, and replies land in one shared inbox. An MCP server with 90+ tools lets Claude and other AI agents drive the whole platform.

Possible disadvantages of OutSystems

  • Cost

  • Learning Curve
    Although it is a low-code platform, mastering OutSystems requires a certain amount of learning and adaptation, especially for developers used to traditional coding.
  • Vendor Lock-In
    Applications built on OutSystems are tightly coupled with the platform, which can make it difficult to migrate to other solutions if needed.
  • Complex Custom Requirements
    While OutSystems is highly flexible, certain complex custom functionalities might still require traditional coding or workarounds, which can increase development time.
  • Performance
    For highly complex or performance-sensitive applications, the abstraction provided by a low-code platform like OutSystems can sometimes lead to suboptimal performance.
  • Limited Offline Capabilities
    Offline capabilities are somewhat limited compared to fully native development options, potentially restricting the use cases for certain types of mobile applications.
  • Dependency on Proprietary Tools
    Relying on OutSystems means depending on proprietary tools and services, which could be a disadvantage if the company decides to change its toolset or strategy.

Questions & Answers

As answered by people managing OutSystems and CampaignStack.

Which are the primary technologies used for building your product?

CampaignStack's answer:

CampaignStack runs on a TypeScript stack end to end.

  • Frontend: React with TanStack Router, built with Vite, styled with Tailwind
  • Backend: Convex, handling queries, mutations, scheduled jobs, and the real-time subscriptions behind the dashboard and the inbox
  • Outreach execution: a separate Node.js service driving real Chrome browser sessions, each pinned to its own residential proxy
  • AI layer: an MCP server exposing 90+ tools, so Claude and other agents can drive campaigns, leads, workflows, and the inbox
  • Plus a Chrome extension, Stripe for billing, and Playwright and Vitest for the test suites

Why should a person choose your product over its competitors?

CampaignStack's answer:

CampaignStack protects the one asset in outbound that cannot be replaced: the client's LinkedIn account. Once it is restricted, no amount of spend brings it back.

Against tools like Expandi, Dripify, Waalaxy, HeyReach, Skylead, and Dux-Soup, which compete mainly on volume and speed:

  • Daily caps are enforced and visible, set at 80% of LinkedIn's tolerance rather than left to the operator to guess
  • Each account runs on its own residential IP, not a shared pool
  • Nothing leaves an account until it passes a review gate, and auto-send is off by default
  • $99 per workspace per month with unlimited connected accounts, so adding clients does not mean buying seats

Everything else is still there: campaign orchestration, ICP scoring, buying signals, A/B testing, and one shared inbox across every account and client.

What makes your product unique?

CampaignStack's answer:

CampaignStack is a LinkedIn and email outreach platform built around one rule: show the sending limit, and refuse to cross it.

  • Every connected account gets a hard daily budget per action type, capped at 80% of what LinkedIn tolerates
  • New accounts ramp up over weeks instead of running at full volume on day one
  • One dedicated residential proxy per account, never a shared IP pool
  • A persistent browser fingerprint, so the account looks like the same person signing in from the same place each day
  • AI drafts every message, a human approves it in a review queue, and auto-send stays off until you turn it on

Most tools in this category bury their limits in a settings page. CampaignStack puts the number on the dashboard.

How would you describe the primary audience of your product?

CampaignStack's answer:

CampaignStack is built for B2B lead generation agencies running outbound for several clients at once, sized for 5 to 20 client workspaces, where one restricted profile means a lost retainer.

It also fits:

  • Founders doing their own outbound with no BDR team
  • Sales operators running a group of reps from one dashboard
  • Consultants delivering demand for several clients while working like it is one

All of them share one constraint: they need volume, and they cannot afford to lose an account getting it.

What's the story behind your product?

CampaignStack's answer:

CampaignStack is built by a small team that spent years inside the LinkedIn automation industry, watching client accounts get restricted by tools that sent too much too fast. The pattern was always the same: the tool advertises volume, the agency turns it up, and a few weeks later a client's account is limited and the retainer is gone. Nothing on the market showed you the line you were about to cross. So we built the platform we wanted to use, one that treats a connected account as something you cannot get back.
