Split raises $17M Series B led by Lightspeed, allows companies to test out new software features and deliver them in a targeted way to select groups of users

Context & Ripple Effects
Split's $17M Series B lands it squarely in the emerging feature-flagging and progressive-delivery category, where the pitch is that companies stop shipping features to everyone at once and instead test them on select user segments first. The follow-on coverage validates the bet: three years later Split raised a $50M Series D led by Owl Rock, bringing its total to $110M on essentially the same thesis.
For lead investor Lightspeed, the round is one node in a busy 2018 dev-tools run — weeks later the firm announced $1.8B in new funds, roughly $1.05B of it earmarked for more mature startups, and it also joined Testim's automated-testing Series B the following year.
First-order effects
- Split gains the capital to scale its feature-testing-and-targeted-delivery platform, while Lightspeed secures an early position in a release-management tooling vendor it would keep backing through later rounds.
- Engineering teams evaluating rollout tooling now have a well-funded dedicated vendor, sharpening the choice between adopting feature flags as a service versus building them in-house.
Second-order effects
- Adjacent quality-assurance vendors feel the pull: Testim's AI-based testing round drew Lightspeed participation, signaling investors are funding the whole release-pipeline stack — flags, testing, delivery — rather than single-point tools.
- As targeted rollouts become standard practice, product teams' expectations shift toward per-segment experimentation, pressuring rivals without comparable delivery controls to add them or cede the workflow.
Third-order effects
- If the pattern holds, software release management consolidates into an infrastructure layer — controlled exposure, measurement, and rollback sold as a platform — much as Split's own path from $17M Series B to a $110M total suggests the category matured rather than stayed niche.
- Investors increasingly treat developer-workflow tooling as a repeatable venture theme, with firms like Lightspeed building portfolios across the release lifecycle instead of betting on individual point solutions.
The trend: Software delivery is moving from big-bang releases to data-driven progressive rollouts, with venture capital systematically funding the feature-flag and testing infrastructure that enables it.
