Built For/Startups

Web runtime for early-stage products

Your agent deploys the waitlist page, creates the NPS form, sets up analytics. Same conversation. Why build this twice?

Updated March 2026

Problems we solve

Problem

This quarter it is a waitlist. Next quarter it is NPS and bug reports. Every new form type means more backend plumbing alongside the actual product. Your agent can scaffold it, but someone has to maintain it.

With Sutrena

The agent creates everything through Sutrena's API. Waitlist, feedback, NPS, bug reports -- one API call each. Deploy landing pages alongside them. When priorities shift, your infrastructure does not need to change. That is the whole point.

Problem

Investors ask for data. How many signups? What is the NPS? You do not have time to build internal tools for reporting.

With Sutrena

Built-in analytics with query primitives. Track signups, visitor counts, referrer breakdowns, and conversion funnels through the API. Share analytics publicly or query them programmatically for investor updates.

Problem

Requirements change constantly. Rebuilding forms or migrating data every time you pivot wastes runway.

With Sutrena

Forms and pages are mutable through the API. Change fields, update labels, swap the success message, update page HTML. Existing submissions stay. No migration.

Problem

Enterprise form tools charge hundreds a month for stuff you do not need yet. Free tiers have submission caps that choke you right when things start working.

With Sutrena

Free forever for small experiments -- 10 projects (forms, pages, analytics, and automations combined). Pro is $29/month with 100 projects and unlimited submissions. No per-submission fees ever.

Problem

This quarter it is a waitlist. Next quarter it is NPS and bug reports. Every new form type means more backend plumbing alongside the actual product.

With Sutrena

Every form type uses the same API. Waitlist, feedback, NPS, bug reports -- one API call each. Deploy landing pages alongside them. When priorities shift, your infrastructure does not need to change. That is the whole point.
