Summit Partners L P has filed trades across 6 companies (mainly through SEC (Form 4)), most often in Klaviyo, Inc., A10 Networks, Inc. and LifeStance Health Group, Inc. Between 28 January 2016 and 11 August 2026, the trades on record add up to 40 filings.
Every open-market trade on record is a sale: 9 sales worth €211.7M. The amount is not disclosed for 1 filing. The rest of the record consists of 2 share grants. Since January 2026: no purchases and 1 sale on the market.
The record was last updated on 13 August 2026 with a transaction in Klaviyo, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
