Custom software.Startup speed.Enterprise power.

QStart Labs is a software engineering firm that designs, builds, and then runs custom software for the companies that depend on it. The work spans custom web applications, native iOS and Android apps, production AI features, AWS cloud architecture, security and compliance engineering, and managed hosting once a system is live. The firm has been building since 2008 and is based in Dublin, Ohio, in the Columbus metro, with an entirely US-based team.

Since 2008, when the firm was founded as a venture capital firm's in-house technology team — building for founders whose runway was measured in months. More than 100 startups have launched with QStart Labs since, partner companies have raised over $50 million, and five have exited. That origin still shapes how engagements run: scope tightly, ship something real, and treat someone else's runway as a constraint rather than a detail.

The senior people who scoped it. QStart Labs does not run a model where a principal wins the work and hands it to whoever is available — the engineers and architects in the discovery conversation are the ones who build the system, and you have direct access to them rather than to an account manager in between. Teams are deliberately small and senior, which is also why the firm does not take on more work than it can staff that way.

A deliberately narrow stack the team runs in production every day rather than a different framework per project: Java and Spring Boot / WebFlux on the backend, Nuxt and Vue on the front end, native Swift for iOS and Kotlin for Android, and Aurora PostgreSQL for data. Infrastructure is AWS — ECS Fargate, infrastructure-as-code with AWS CDK, and AWS GovCloud where a workload requires it. AI work runs on Amazon Bedrock and Azure AI Foundry with pgvector for retrieval and Langfuse for observability.

Production systems, and the difference is mostly what surrounds the model. A demo needs a prompt and an API key; a system real users depend on needs evaluation, observability, cost control, human review where the stakes justify it, and a clear answer about what happens to your data. QStart Labs builds retrieval over private data, AI voice agents, sales assistants, and agent workflows with that operational layer attached — with Langfuse tracing on the calls, so when an answer is wrong you can find out why.

Yes — regulated and audited environments are a large part of the practice. That covers HIPAA-aligned builds, SOC 2 readiness, penetration testing, and vulnerability management with remediation SLAs, and it extends to systems running in AWS GovCloud under CJIS requirements for public-safety clients. QStart Labs is an AWS Select Tier Partner. The firm's own SOC 2 and ISO 27001 programs are in progress, and are always described that way rather than as completed certifications.
