We are focused on accelerating organ regeneration and recovery innovations based on the convergence of bioelectrics and biologics.


We work within these product groups

1. Heart & Cardiovascular.
2. Brain.
3. Cosmetic & Personal Care.
4. Major Organ Regeneration.
5. Cancer.

We have assembled an all-star team of experienced veterans that have taken multiple products from concept stage to helping save and improve the quality of life of hundreds of thousands of patients.

Our base technology IP platform is based on:

  • (1). Bioelectric signaling sequence controlled expression of more than 20 organ regeneration proteins including stem cell homing factors.
  • (2). A re-fillabable micro infusion pump.
  • (3). A multicomponent stem cell + support factors composition for organ regeneration.

We strive to recover all damaged or diseased organs with non-invasive bioelectric signaling and only resort to more invasive therapies when non-invasive means has not resulted in full recovery.

Cal-X: The Story Of The California Stock Exchange


Debate about equity crowdfunding at Crowdfunding California …

What we look for when investing in outside founded innovations and startups…

At Leonhardt Ventures we recognize and accept risk; nevertheless, we look for several factors to help anticipate and mitigate these challenges.

Innovation Culture:  Rapid prototyping.  DO things.  Do, fix, try, repeat.  Fail forward fast.  Try a lot of stuff and keep what works.  Freedom to make some mistakes.   Ready, fire, aim.  Get on with it.  Don’t talk about it or analyze it, do it!
Ability to Communicate Vision:  “A vision is meaningless if it does not have the power to persuade, and it cannot persuade if nobody knows about it – marketing the vision is everything!”  Carmine Gallo, Author
Human Capital Matters: We invest in people.
Technology Matters:  Invent something unique that is truly better.   Better technology DOES matter.  Better technology IS possible.
Sales:  Sell something now to cover overhead while you build your great blockbuster product innovation over time.
Continuous Improvement:  Committed to improving the company, the products, customer service every day.
Customer Centric Focus:  Exceed the customers expectations.  Not just happy but delighted customers.  Repeat customers.
Listening: We have yet to see an entrepreneur succeed without being able to listen — to customers, employees and sometimes even investors.
Transparency: Integrity, openness, and honesty are essential.
Large Market: A large market provides a cushion and mitigates unforeseeable risks.  It takes just as much time, effort and money to address a small market properly as a large market so you might as well go after large markets.
Nail It: Formulate and apply a customer-validated value proposition.  We are big fans of “Lean Startup” and “Nail, then Scale It” methods for applying a process to the black box of the entrepreneurial journey.
Avant-Garde Approach: Find your competitive advantage. Chart unfamiliar waters. Create unique solutions. Be a first-mover.
Momentum: Generally, if companies can’t generate momentum without money, things don’t change after they do. Maximize sweat equity into building traction.
