About the FundedIQ Series B Energy startup funding data

FundedIQ tracks announced startup funding rounds and organises them by company, funding date, stage, amount, industry, location and investor. The dataset is refreshed weekly, and new rounds are normalised and de-duplicated before they are published, so the same round reported twice on different dates is recorded once.

Figures on this page cover the 133 funded Series B Energy startups currently tracked. Round counts, capital totals and the median round are computed over a trailing 24 months. Rounds whose amount was not disclosed (10 of 62 in that period) are counted as rounds but excluded from capital totals and from the median. The most recent round on record for funded Series B Energy startups is dated Aug 2026.

The table above shows the 100 most recently funded companies. Full funding histories, investor lists and founder contacts across the whole dataset open on a FundedIQ plan.
