About Ott Kaukver
Ott Kaukver is a technology executive and investor. He started at Skype in 2004 as Director of Operations and went on to lead engineering there, first for core technology and then for consumer products, until 2012. Earlier roles were at Helmes and at the Estonian agency Zero Digital Media / XXL.EE.
He joined Twilio as VP of Engineering in 2013 and later led its voice and video business. Crunchbase lists him as Twilio CTO from 2018 to 2019. He was Executive in Residence at Bessemer Venture Partners from 2019 to 2020. He then served as CTO of Checkout.com from January 2021 to December 2023.

Crunchbase counts 28 investments and 22 portfolio companies, and PitchBook counts 24 investments. Different databases give different totals, so treat these as approximate. The record goes back to Pipedrive, where he was an advisor and investor from 2013 to 2016, and Wise, which he advised from 2012 to 2017.
Crunchbase lists exits including Pipedrive, Printify and Qatalog, and PitchBook shows Stilt as a later-stage round. Some early bets did not last: PitchBook marks NFTPort and Propel as out of business.
His latest listed deal is Handhold, a Tallinn AI-agent platform that handles inbound software buying journeys. It raised a €3M seed in April 2026, led by Entourage Capital with Inovia Capital and e2vc. Kaukver is named among the angels, alongside Markus Villig, Harsh Sinha and Janer Gorohhov.

EasyVC lists his stages as pre-seed and seed, and his portfolio also includes Series A and later rounds such as Arcjet, Qovery, Sereact and Lightyear. Crunchbase and PitchBook categorise his deals mostly as business software and software development tools. AskForFunding lists his interests as developer tools, AI, fintech and infrastructure. Most of the companies named in the sources are European, many of them Estonian. He has not published a check size or a statement of what he looks for, so none is given here.
