Execute convertible note and receive funds
Sign the convertible note agreement with CT Innovations. Funds disbursed as a lump sum. No personal guarantee required. Note converts at the next qualifying funding round at a discount to the round valuation, or is repaid upon agreed terms if conversion doesn't occur.
~4 hrs
CT Innovations funds only 15–25 companies per year from hundreds of applications — be ready to clearly articulate why your technology is defensible. The 'pay-it-forward' culture means alumni mentors are accessible; connecting with a CT Innovations portfolio founder before applying materially helps.
Deadline & timing
CT Innovations reviews applications on a rolling basis with no hard annual deadline. However, the due diligence process is extensive — 3.5 to 24 months from pitch submission to final approval. Plan accordingly: this is not a quick-turnaround fund. Submit early if you need capital within the year.
