About FundedIQ's Ameresco Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Ameresco is left off this page rather than filled in.
