TransferSlot Alternatives
ROI & payback layer for verified listings
TransferSlot curates indie SaaS deals nicely, but the buyer still has to do the ROI math and trust seller-reported numbers. Startup Index adds live TrustMRR verification and puts annual ROI and payback in months on every card, so you shortlist on numbers instead of vibes.
