Previo
Relying on third-party systems?
Solution: Previo depended on a 3rd party booking sync tool that was slow and unreliable, so we built them a custom Channel Manager, giving them full control and stable performance.
Result: Faster, reliable syncing across portals and a scalable foundation for expansion

Rockpoint Legal Funding
Scaling operations on spreadsheets?
Solution: Rockpoint Legal Funding outgrew a simple web app and Excel. We built them a custom platform that runs the whole operation: customer onboarding, case processing, contract signing, banking reports. It now handles $150M+ in funded cases, up from less than $10M when we started.
Result: Faster processes, leaner operations, and 5x faster growth than competitors' growth.

Futurestay
Founder-built prototype isn't working?
Solution: Futurestay started on a basic DIY system that was slow and outdated. We modernized the codebase, unified property management, and integrated Airbnb and Booking.
Result: A stable, scalable platform powering global growth - 64,000+ properties managed and $2M in funding secured.

Tentacles IoT
Left with half-done apps?
Solution: Tentacles IoT burned its budget and got stuck in the middle of the app development. We fixed their back office app, finished the mobile app in Flutter with a single codebase instead of separate Android or iOS.
Result: A completed, reliable product that cut costs by 50% and secured new customers and contracts.

QuantPedia
Stuck with outdated, unscalable tech?
Solution: QuantPedia was too complex to scale. We rebuilt it on WordPress with custom pods and full data migration for easy no-code updates.
Result: Content can be updated in minutes, subscriptions grew by 300%, and the team scaled from 1 to 14 without relying on developers.
