Stop bleeding money on vendors

Your SaaS budget has a 30% leak.
BuyStack plugs it.

An autonomous AI agent that monitors every vendor relationship, catches renewal traps, negotiates better terms, and kills subscriptions nobody uses. It works 24/7 so your finance team doesn't have to.

$1.8T

Global SaaS spend in 2026. A third of it is wasted on unused licenses, duplicate tools, and auto-renewals that slip through.

130+

Average number of SaaS tools at a mid-size company. Nobody knows what they all cost. Nobody manages the renewals.

What most growing companies spend on procurement. No dedicated person. No system. Just credit cards and hope.

24/7

BuyStack never sleeps. It monitors contracts, flags upcoming renewals, drafts counter-offers, and finds cheaper alternatives before you overpay.

How it works

One agent replaces your entire procurement process

Discover

BuyStack connects to your email and billing systems to map every vendor relationship, contract term, and renewal date automatically.

Analyze

It identifies unused licenses, overlapping tools, and contracts where you're overpaying compared to market rates. You see the waste in dollars, not dashboards.

Negotiate

Before every renewal, BuyStack drafts a counter-offer based on competitive pricing, your usage data, and proven negotiation playbooks. You approve, it sends.

Optimize

Continuously monitors for cheaper alternatives, consolidation opportunities, and new vendors that offer better value. Your stack gets leaner every month.
