Bold Tech has been building internal tools on Retool for 5 years now, and to honour this occasion we're excited to share more about our story, and how Retool has shaped the way we work.
At Bold Tech, our mission has always been clear: reduce complexity, deliver impact, and make internal tools not just functional, but satisfying. Over five years and 50,000+ hours of development time, Retool has been a cornerstone of that mission.
From helping scale startups to transforming enterprise back offices, we’ve pushed the boundaries of what’s possible for internal tools and what can be done on the Retool platform itself. This blog post is a look back at the innovations, best practices, and UI craftsmanship that have defined our collaboration with Retool on this exciting anniversary and a preview of where we’re headed next.
Our beginnings
In 2020, after months of building on the platform and quickly becoming the top contributor on the Retool forum, Joey was introduced to Retool’s Growth team to support new enterprise customers - like Stripe - with their buildouts. At the time, Retool was still in its early growth phase and looking for a partner who could showcase the platform's full potential and build deep, trusted relationships with clients.
Fast forward a few years... Retool has steadily evolved into the business software powerhouse it is today and, with a rich legacy and deep-rooted expertise in the platform, Bold Tech has solidified its role as a key development partner. Having worked closely with Retool as it’s grown from a 40-person to a 400+-person company, Bold Tech brings a level of historical context and enterprise expertise that’s difficult to replicate.
In 2021, we launched our blog to share that expertise - collaborating with the Retool content team to publish tutorials, guides, and videos that help developers build faster and smarter on the platform.
Along the way, the Bold Tech team has produced tons of unique learning pieces for the Retool community. We've received great feedback from customers and developers on how our blog has helped them build better in Retool - a huge thanks to everyone who takes the time to read it.
Here are some of our favorites over the years:

The clients that made it all happen
We’ve had the pleasure of working with incredible clients across a multitude of industries: Edtech giants like Seesaw, Fintech enterprises like Bilt, Ramp and Stripe. We’ve also supported plenty of plucky SMBs and start-ups with scaling their ideas, growing and developing increasingly complex, customized systems to support their unique and often-changing models.
We’re lucky to have worked closely with so many great teams and innovative companies, and we’ve learned tons about all the technology that goes into making them the well-oiled machines they need to be.
What’s more, our ever-growing portfolio of enterprise clients has allowed us to become specialists in large and secure internal infrastructures that require the highest levels of data compliance, so much so that we now have a dedicated DevOps engineer to support teams with complex deployment.
Bold Tech: five years on
Now, Bold Tech is a tight-knit crew of 14 and has delivered over 50,000 hours of development work for more than 80 clients. This depth of hands-on experience has given the developers a deep understanding of the platform’s nuances—along with a toolkit of performance, security, and UX best practices that only come from time in the trenches.
What sets Bold Tech apart is how we select developers: each member is chosen not just for technical skill, but for their ability to translate complex business logic into effective, intuitive applications. We thrive on being dropped into unfamiliar, high-stakes challenges—and designing tools that solve them with clarity and precision, from UI to backend logic. We work to align ourselves as brains for hire that go beyond the typical task-based, agency-style engagements.
Special mention goes to Stefan, our Head of Development—a Retool-obsessed magician whose precision and creativity continue to push the platform’s limits.
While Bold Tech has long been a trusted center of excellence partner—known for building powerful, user-friendly internal tools on Retool—the scope of its work has expanded significantly in recent years. With thousands of hours of development and deep exposure to the technologies surrounding Retool in real-world environments, we now operate at a higher level of advisory—supporting clients not just in what they build, but in how they scale, secure, and structure their internal tooling.
Here is a selection of these new services we are proud to offer:
DevOps for Retool at Scale
Bold Tech helps organizations deploy, manage, and optimize their Retool instances across complex environments. From self-hosted setups to highly complex cloud configurations, we ensure that infrastructure is resilient, secure, and built for long-term maintainability.
Enterprise Permissioning Frameworks
Robust access control is critical for any serious Retool implementation. Bold Tech works with clients to design and implement permissioning models that map cleanly to organizational roles, compliance needs, and security best practices—ensuring the right people see the right data at the right time.
SaaS Product Architecture in Retool
For SaaS companies building customer-facing or operational tools directly within Retool, Bold Tech provides architectural guidance on how to structure multi-tenant apps, enforce data isolation, and streamline workflows. This goes beyond building fast—it’s about building responsibly, with scalability and product quality in mind.
Training & Enablement
Whether it’s onboarding new teams, documenting best practices, or running interactive workshops, Bold Tech helps clients level up their internal Retool fluency so they’re enabled to build better too.
Looking ahead
Looking ahead, Bold Tech remains as committed as ever to raising the bar for what internal tools can be. We’ve spent the last five years playing our part in Retool’s evolution from the inside—through code, content, and client outcomes—and we’re just getting started. As the complexity of modern businesses grows, so does our ambition to solve their hardest operational problems. Whether it’s standing up secure, enterprise-grade infrastructure or helping a founder turn their back-office chaos into clarity, Bold Tech is here to be more than a vendor—we’re your internal tools partner of record. Here’s to what we build next.
