Review management API for marketplaces

Add verified reviews, review data from 80+ sites, AI replies and review requests to your marketplace with one API.

Reviews run your marketplace. Building them shouldn't slow it down

01
Trust is the product

Buyers decide on reviews. Unverified or fake reviews cost you conversions and the trust of both buyers and sellers.

02
Reputation lives everywhere

Your sellers' reputation also lives on Google, Facebook and dozens of other sites your platform can't see today.

03
Every new flow is a project

Collection, verification, moderation, replies and removal pull engineers off your core roadmap.

Time to launch

Days to weeks: launch your review product without pulling your dev team off existing priorities.

12–18+ months: product scoping, hiring, building, and testing before you can even launch a V1.

Upfront cost

$500–$10k depending on products used, API vs. white label, and customization.

$300k–$600k+ in dev salaries, infrastructure, and diverted resources before launch.

Ongoing maintenance

SAU handles review site changes, API updates, scraping, hosting, uptime, bug fixes, and feature updates.

Every change to a review site, API, or UI requires new dev work, bug fixes, and QA from your team.

Core product focus

Keep your team focused on building core product features while SAU handles review management.

Diverts engineering resources for 12–18+ months away from your core product roadmap.

Reliability & scalability

SAU infrastructure is built to handle tens of millions of locations without performance drops.

Untested until launch. Scaling requires more infrastructure, costs, and dev time.

One API. 80+ review sites.
