Building a Startup in St. Louis: What You Need to Know
St. Louis has established itself as a critical hub in the American tech ecosystem.Biotech and geospatial tech with Cortex innovation district. For founders building here, the challenge isn't just about having a great idea—it's about executing with the right technical team.
The St. Louis Startup Engineering Challenge
Many St. Louis founders face a critical decision early in their journey: should they hire a full-time CTO, work with an agency, or find a different path? The reality is that seed-stage startups often can't afford a full-time CTO (market rate: $300-500K+), yet agencies deliver rotating contractors who treat your product like just another ticket.
This is where fractional CTOs and founding engineers become essential. You get senior technical leadership and execution without the full-time commitment or agency overhead. At HyperNest Labs, we've helped Midwest startups navigate this exact transition—from pre-seed through Series A and beyond.

When to Hire a Fractional CTO vs. Full-Time CTO
A fractional CTO makes sense when you're between $0-$3M ARR and need technical leadership for 10-25 hours per week. Once you hit Series A and have proven product-market fit, transitioning to a full-time technical leader often makes sense. Our fractional CTOs frequently help hire and onboard their permanent replacement—ensuring continuity and a smooth handoff.
