StackSwap is a free GTM stack audit that surfaces tool overlap, redundancy, and waste in B2B sales tech stacks. Built for founders, RevOps leads, and sales operators who need to cut SaaS spend without losing capability.
Unlike SaaS Management Platforms (Vendr, Zylo, Productiv, BetterCloud), StackSwap is self-serve and integration-free. You don't connect billing data or wait on procurement workflows โ you get a directional audit in under 60 seconds. Great as a first-step diagnostic before adopting an SMP, or as a standalone tool for teams that just want to cut overlap.
GTM tooling we score includes CRM, sales engagement, data enrichment, intent data, ABM platforms, conversation intelligence, marketing automation, customer success, and more.
StackSwap React EngineStackSwap's answer
Most SaaS spend tools โ Vendr, Zylo, Productiv, BetterCloud โ require integrations with billing, SSO, or HRIS before they tell you anything. They're heavyweight onboarded platforms. StackSwap is the opposite: drop in your tool list, get a structured audit in ~60 seconds, no integration. Overlap surfaced by category, with keep / replace / remove calls. It's the diagnostic step before the platform commitment, not a replacement for it.
StackSwap's answer
Two reasons:
Speed. SaaS Management Platforms take 2-6 weeks to onboard and another 30-60 days to surface useful insights. StackSwap takes 60 seconds. Different product class.
Cost. SMP contracts start around $20k/yr. The free Stackscan covers most of what a founder or RevOps lead needs to start the consolidation conversation.
Honest take: if you're already running an SMP and getting value, keep it. StackSwap is the faster diagnostic, not the replacement. If you're shopping the SMP category, run StackSwap first to see what you actually need before sitting through five demos.
StackSwap's answer
B2B SaaS founders, RevOps leads, and Heads of Sales / Marketing / Revenue at companies in the 10-200 employee range โ typically post-seed, pre-Series-B โ where the GTM stack has grown organically and nobody owns the audit. Common trigger: a board meeting where someone asks "are we paying for tools we don't use?"
Also: buyers evaluating the SaaS spend management category who want a directional read before sitting through enterprise sales cycles.
StackSwap's answer
I spent 10 years in B2B SaaS sales โ BDR through Head of Revenue โ selling into hundreds of mid-market and enterprise teams. I watched companies pay six figures a year for two competing data enrichment tools because nobody owned the audit and nobody wanted to fight the renewal motion.
StackSwap is the tool I would've hated to face as a vendor on the renewal call: free, fast, takes the buyer's side, names overlap by name. The category I sold in for a decade gets auditable.
StackSwap's answer
Next.js 14 (App Router) on Vercel, TypeScript, Supabase (Postgres + Auth + Storage), Stripe for billing, Anthropic's Claude API for LLM-assisted analysis, Sentry for observability.
Built deliberately on a thin stack โ the irony of running a tool-overlap audit on 30 SaaS subscriptions wasn't lost on me.
