About Harsh Sinha
Harsh Sinha is Chief Technology Officer at Wise, formerly TransferWise. He leads the technology team that builds the company's cross-border payments network. Third-party data sources list him as CTO since May 2015, and as interim CEO of Wise from September to December 2023.
Before Wise he was director of product at PayPal, where he led product strategy and development for PayPal's mobile apps and software. Earlier he led technology functions at eBay, including eBay Motors and eBay local.
He holds an MBA from the Haas School of Business at UC Berkeley and a bachelor's degree in Computer Engineering from Sikkim Manipal University, India. His X profile lists Austin, London and San Francisco as his locations.
Wise's conference speaker bios describe him as an angel investor and an advisor to early-stage startups and venture capital firms. Crunchbase says he advises early-stage startups on product-market fit and team scaling. It records 10 personal investments, and NFX Signal also lists 10.
NFX Signal dates several of these rounds: Tem-Energy Series A (September 2024), Omnea Series A (October 2024), Spiko Series A (July 2025), Finary Series B (September 2025) and Handhold Seed (April 2026). Other databases also name Tracebit, Lightyear, Belvo and Compa in his portfolio, without dates.
His AI investment on record is Handhold. Handhold is a Tallinn-based AI-agent platform for software companies. It announced a €3M Seed round on 8 April 2026, led by Entourage Capital with Inovia Capital and e2vc. Sinha took part as an angel, alongside Markus Villig (Bolt), Ott Kaukver (former CTO of Twilio) and Janer Gorohhov (Veriff).
Handhold's agents qualify leads, run demos and manage customers through to renewal. We found no other investments by Sinha that are clearly AI-native.
Sinha has not published a thesis that we could find. His record points to early-stage rounds, from Seed to Series B, mostly in fintech and software, in European and US companies.
NFX Signal lists an investment range of $100K to $5.0M with a $1.5M sweet spot. That figure comes from a third-party database, not from Sinha, so treat it as indicative.
