How Flex Gave Every Employee an AI Builder Without Losing Control of Its Data
170 apps in 90 days, built by 18 departments, all inside Flex's own AWS account and on their own Snowflake permissions.

"Superblocks in our AWS private cloud is available to every employee at Flex. We have 70 apps used daily across 18 departments in our first 90 days."
Flex gave every employee AI tools, then had no way to ship what they built.
In February 2026, Flex leadership went all in on AI and handed every employee access to the frontier coding agents with no limits. People built useful things fast. Then the apps stopped at the edge of their laptops, and as a fintech, Flex had no answer for who could access them, where they would run, or what they were touching.
"Teams were building solutions, but it only worked on their laptop. The only way you could share was really copy-pasting something or doing a Zoom call, and that's frankly terrible."
Domain experts become app builders
Flex evaluated Replit, Vercel, Lovable, and others before AWS introduced them to Superblocks. The decision came down to control on the IT side and simplicity on the builder side.
"These other tools expose too many knobs that non-technical users don't understand. Version control, deployments, integrations, database persistence, backups. Making them responsible for that was a nonstarter. Superblocks struck a really nice balance of abstracting a lot of that away while not restricting them."
Clark as co-builder. Non-technical users prompt Clark to generate database schemas, APIs, and full application logic. The team uses a UI-first approach: build the interface, then Clark generates everything underneath.
IT stays in control. Self-hosted in Flex's own AWS account. Role-based access control, integrations provisioned centrally by IT, and full audit data on every app and every prompt.
Set up centrally. IT connects Snowflake and Flex's internal APIs once, then hands them to builders ready to use.
Built inside Flex's own AWS account
Flex hosts all of its critical systems itself and would not delegate that perimeter to a vendor. Superblocks runs fully self-hosted inside Flex's AWS VPC, on the same stack Flex already operates.
"We felt very strongly that we didn't want to open up that perimeter and delegate that kind of responsibility to any vendor. None of the other providers offered a solution that let us keep that control."
Access to Snowflake was already broad at Flex. SQL was the barrier. Superblocks passes each user's own identity through, so Flex never had to rebuild its permission model in a second system.
"We don't want to rebuild that experience, we already did it in Snowflake. Users bring in the Snowflake integration, go through their sign-in, and have access to all the same exact data."
Quality Management System
Flex's support organization ran quality assurance in a third-party tool that would not measure what they needed. A member of the support team rebuilt it in Superblocks, backed by Snowflake, and it is already running against live data.
Grading on Flex's rubric, not a vendor's. Ticket grading and QA reviews configured to how Flex actually evaluates support quality.
Audit logging from day one. Every review and change recorded, which is what made a production rollout possible.
Retires a paid SaaS tier. Rebuilt in-house on data Flex already owns.
Commissions Engine
Sales payouts at Flex were calculated across three data platforms, assembled in a spreadsheet by hand every month, then approved over chat and email. A revenue operations builder replaced all of it with one app.
One engine instead of three systems and a spreadsheet. Every source feeds a single calculation.
Approvals with an audit trail. Managers approve payouts and flag disputes in the app.
Built by the domain owner. The person who runs comp built the tool that runs comp.
"We're really excited about the opportunity to move it all into an automated system and stop having to manually run commissions every month."
Some of the apps being built by the business
Flex's most active departments are customer support, legal and compliance, and revenue. 16 of 18 departments have active builders.
