Customer.io: Funding, Investors & Team (Aug 2026)
Customer.io is a SaaS product that provides infrastructure to send triggered emails users to improve an app’s engagement level with users. Customer.io receives data about user behavior through on-site javascript code as well as a RESTful API.

Users who match conditions receive emails encouraging them to change their behavior. Customer.io measures the effectiveness of those emails and allows its customers to continuously tweak and improve their triggered email campaigns.

About FundedIQ's Customer.io 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 Customer.io is left off this page rather than filled in.
