Without someone technical to lead with confidence, everything starts to feel harder than it should.
You know what to build and why. But turning that into architecture, hiring developers, and guiding a build? That's where it gets murky. Without someone technical to lead with confidence, everything starts to feel harder than it should.
You might not need a full-time CTO. What you need is someone who can step in, make the right technical decisions, and keep things moving, without the cost, delay, or risk of a full-time hire.
Dev work is getting done. But without a clear roadmap, aligned priorities, or a technical point of view, it's all output with no real direction. Code piles up. Costs increase. And the foundation isn't strong enough to scale.
