The Story Of Brenner Software With Tim Brenner

Written By xavi umeh

Tim Brenner, founder of Brenner Software, joins us in this episode of Ace Founder podcast.

We discuss how he transformed a personal frustration with manual engineering tasks into Steelworks, a highly specialized software for metal fabrication shops.

We also cover his journey from an aerospace mechanical engineer building Excel macros on the weekends to bootstrapping a startup that saves fabricators days of manual data entry.

If you're curious about the power of extreme niching, doing unscalable things like knocking on shop doors to get your first customers, and why you might want to rethink slapping an "AI" label on your product, this episode is an absolute must-listen.

📚 What We Talk About:

  • 01:11 — The unexpected emotional toll of startup rejections and becoming numb to the word "no."

  • 03:24 — How Tim’s background as an aerospace mechanical engineer led him to despise repetitive manual tasks.

  • 04:42 — Teaching himself VBA to write Excel macros and accidentally building a mini-MRP system for his day job.

  • 06:20 — Buying back his own intellectual property to turn a weekend passion project into a full-fledged web application.

  • 08:23 — The magic of physical manufacturing and the thrill of seeing a 3D CAD model turn into a real-world product on the shop floor.

  • 10:02 — Why he named the company Brenner Software and the core problem their flagship product, Steelworks, solves for metal fabricators.

  • 12:22 — How Steelworks takes a 5,000-part 3D model and automatically generates a perfectly accurate shopping list in 30 seconds.

  • 18:33 — Why Tim avoids standard cold email campaigns and his unique, value-first approach to outbound sales.

  • 21:36 — A spicy take on LinkedIn's "AI slop" and why the platform is losing its authenticity.

  • 23:33 — Doing things that don't scale: How Tim landed his first 10 customers by physically knocking on fabrication shop doors.

  • 26:12 — Differentiating from the competition by integrating directly into CAD software to prepare data before it even hits the ERP system.

  • 29:13 — Why AI is a double-edged sword that is slowly deteriorating human critical thinking and problem-solving skills.

  • 40:00 — Refusing to slap an "AI" badge on Steelworks and why deterministic algorithms beat machine learning in manufacturing.

  • 44:33 — Tim's advice for aspiring founders: get deep industry experience to find expensive, invisible problems to solve.

💭 Key Quotes:

  • "I really hated doing things manually."

  • "AI's not knocking on doors."

  • "If you can automate something with processes, procedures, and algorithms, that would always be my number one attempt."

  • "Get some experience, see some really specific problems, and try to solve them."
