Greptile says it raised a $50 million Series B led by Menlo Ventures

Greptile says it has raised a $50 million Series B led by Menlo Ventures, valuing the company at $750 million. The figures are in a company blog post dated October 19, 2026, and in a post the same day from Greptile's official account.

The blog post, "Series B and The War on Bugs," is bylined Daksh Gupta. It says Jump Trading, Wing, Operator Collective, Benchmark, YC, Browder Capital, and Initialized participated, and that Deedy Das is joining the board. The account post matches the blog on the round size, Menlo Ventures as lead, and the $750 million valuation.

Greptile also says it reviews and tests more than 1% of all pull requests opened on GitHub every day, and that it is the code validator for thousands of engineering teams, including Nvidia, Coinbase, Decagon, and Vanta. The account post repeats that volume claim and those customer names. Neither post explains how the GitHub share is measured. The valuation and the share of daily pull requests are Greptile's own figures.

The case for the product is a check that sits apart from the agents writing the changes. Gupta writes that the best companies use multiple coding agents and run all their changes through Greptile, which "acts as a single, independent validation layer." He writes that coding is "orders of magnitude faster than before," while the impact on a team's ability to ship new features has been modest, because engineers still need to determine whether a change works as intended and whether it will break something for users.

Greptile's stated mission is to automate code validation so teams building mission-critical software can auto-merge complex changes. If the company succeeds, Gupta writes, those teams "will see the true promise of AI coding for the first time." The post says Greptile has made progress and that a lot of work remains. It does not say how the $50 million will be spent, and it does not give revenue or headcount.

Read the October 19 blog post for the investor list and the validation argument, and compare it with the official account update, before treating the round size, valuation, or GitHub share as anything beyond what Greptile itself has said.
