As answered by people managing subby.io and StackSwap.
subby.io's answer
Subby uses AI to automatically discover your subscriptions by securely scanning your Gmail inbox — no manual data entry required. Most competitors make you add subscriptions by hand or connect your bank. Subby takes a privacy-first approach with read-only email access, intelligently categorises everything, and builds your full subscription picture in under a minute.
StackSwap's answer:
Most SaaS spend tools — Vendr, Zylo, Productiv, BetterCloud — 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.
subby.io's answer
Unlike Rocket Money or Trim, Subby doesn't require bank account access — it discovers subscriptions through your email, which is far less invasive. It's free to get started, works across any currency, and gives you renewal alerts before you get charged so you can cancel on your terms. It's built for people who want control without handing over their banking credentials.
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.
subby.io's answer
Individuals and families who've lost track of their recurring subscriptions and want to stop wasting money on services they've forgotten about. Particularly popular with young professionals and budget-conscious consumers who subscribe to multiple streaming, productivity, and fitness services.
StackSwap's answer:
B2B SaaS founders, RevOps leads, and Heads of Sales / Marketing / Revenue at companies in the 10-200 employee range — typically post-seed, pre-Series-B — 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.
subby.io's answer
Subby was born from a simple frustration — realising how many forgotten subscriptions were quietly draining money every month. After manually combing through email receipts to find them all, the idea clicked: why not let AI do this automatically? Subby was built to be the subscription agent everyone needs — one that finds what you're paying for, shows you the full picture, and helps you cut what you don't need.
StackSwap's answer:
I spent 10 years in B2B SaaS sales — BDR through Head of Revenue — 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.
subby.io's answer
Subby is currently in beta and growing its user base organically. It's designed for individual consumers rather than enterprise clients, so our focus is on everyday people looking to take control of their spending.

React Native app for web
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 — the irony of running a tool-overlap audit on 30 SaaS subscriptions wasn't lost on me.
