For CleanTech at the Series B stage, investors focus heavily on: Environmental permits (federal, state, local) by project, Interconnection agreements with utilities, and Project finance model for each asset under development, IRA tax credit eligibility analysis (ITC, PTC, 45X). Cleantech DD includes an independent engineer (IE) report for physical assets. This typically takes 4–6 weeks and is investor-commissioned. Prepare project data packages that match ASTM standards.
Your Series B data room should include: 3 years of audited financial statements; Full customer list with contract terms and renewal dates; Complete IP portfolio with FTO opinion; All board materials and resolutions; Material subsidiary documentation; Insurance policies (D&O, E&O, cyber); All government filings and regulatory correspondence. Use a structured folder system that mirrors investor expectations — most institutional investors use a standard folder taxonomy.
The five most common DD deal-killers are: (1) undisclosed founder litigation or criminal history, (2) IP ownership gaps — particularly for university-origin technology, (3) customer contract terms that prevent assignment on change of control, (4) cap table math errors or undocumented equity grants, and (5) financial restatements required after revenue recognition review.
Executive team professional background investigations. Non-compete and non-solicitation enforceability analysis. Board composition governance review.
