SOC 2 Type II infrastructure.
Tool inputs are processed only to generate your result — written to no database, logged nowhere, not used for training. The Just Ask box is different: what you send there is stored so we can build it — see our privacy page. ExecStack runs entirely on SOC 2 Type II certified infrastructure: Vercel and Anthropic.
Enterprise ready
Deploy in your cloud.
For organizations with stricter requirements — private deployment inside your existing environment. AWS, Azure, GCP. Your data never leaves your infrastructure.

Real tools, already working.
“ExecStack rebuilt my landing page and set up my entire lead nurture — replacing the GoHighLevel setup I was paying for, free. Leads actually reply now, I get notified the moment they do, and everything is captured in one place. I had my first booking within days of going live.”
“ExecStack built my clients a live lever board for renewals. They pull the levers themselves — carve-outs, network moves, stop-loss — and watch millions in benefits spend respond in real time, scenario against scenario. The what-ifs that used to take three meetings now happen in one sitting. Clients were blown away.”
Fresh off the bench
Benefits Contribution Modeler
Move a slider, set the contribution percentage — totals recalc instantly for the company and every employee, with the impact against last year side by side. Benefits decisions in minutes, not spreadsheet rounds.
The kind of tool we build — yours is next
The ExecStack model
Every tool starts with a real conversation about a real problem.
Why free? Because the first tool is how we show you what's possible — no pitch deck competes with a working tool in your inbox. When you're ready for more, we scale it across your company. That's the business.
