Substly helps small and medium-sized companies reduce SaaS sprawl by providing an easily accessible overview and simplifying the processes around SaaS management.

The product offers enterprise-level features at an entry-level price; this tool provides insights into SaaS usage and helps identify user frustrations. It also helps optimize SaaS spending by providing alerts before renewals and eliminating spending on unused accounts. Additionally, it helps avoid unauthorized access to company data by improving employee off-boarding, allowing departments/teams to minimize SaaS sprawl and share an overview with other stakeholders.

Customers highlight the following four aspects of Substlyโ€™s product: - The overview and the control it leads to (regarding costs & who has access) - Great for showcasing status/costs internally - The simplicity of the system - Easy to get started (intuitive and short learning curve)

What StackSwap does

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.

How it works

  • Drop in your current GTM stack (CRM, sales engagement, data enrichment, intent, etc.)
  • Get a structured audit showing where you're paying twice for the same capability
  • See keep / replace / remove recommendations with the cheaper alternative if it exists
  • Free to use โ€” no sales call, no demo, no integration setup

Who it's for

  • B2B SaaS founders trying to keep burn low
  • RevOps and sales ops teams running consolidation reviews
  • Heads of Sales / Marketing / Revenue tasked with cutting tooling spend
  • Buyers comparing the SaaS spend management category before committing to a heavyweight platform

Why it's different

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.

Coverage

GTM tooling we score includes CRM, sales engagement, data enrichment, intent data, ABM platforms, conversation intelligence, marketing automation, customer success, and more.

Analysis of StackSwap

Overall verdict

  • Limited independent information is available about StackSwap (stackswap.ai), so a confident assessment of its quality, security, and reliability cannot be made without further research directly from official sources, user reviews, and independent audits.

Why this product is good

  • Insufficient verified public data exists to confirm the platform's legitimacy, security practices, or track record.
  • Crypto and DeFi-related platforms carry inherent risks, so any swap or exchange service should be vetted carefully before use.
  • No confirmed information on regulatory compliance, audit history, or team transparency was available at the time of this assessment.
  • Users should check for smart contract audits, community reputation, and liquidity/volume metrics before trusting the platform with funds.

Recommended for

  • Users who are comfortable conducting their own due diligence before using a lesser-known crypto/DeFi platform.
  • Not recommended for beginners or those seeking a well-established, thoroughly vetted swap service without additional research.
  • Individuals who prioritize checking audit reports, team credibility, and community feedback prior to using new platforms.

Questions & Answers

As answered by people managing Substly and StackSwap.

What makes your product unique?

StackSwap'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.

Why should a person choose your product over its competitors?

StackSwap's answer:

Two reasons:

  1. 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.

  2. 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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

    Best way to spend money, to save money!

    Using Substly has given us a better understanding of how we use our SaaS-apps and improved our ability to manage software licenses, resulting in better decision-making and cost savings. Substly's overview feature has been particularly helpful in this regard. Additionally, the offboarding feature has streamlined the process of removing software access for departing employees.
