What is Convex?

Convex raised $57M on the argument that agents need a backend built for them.

The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.

What is Rivet?

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

Convex raised $57M on the argument that agents need a backend built for them.

◆ Current state

The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.

◆ Where it's heading

Convex is funding and positioning ahead of shipping. The enterprise release established the upmarket motion and the funding narrative attaches it to agent-written code, but nothing in the visible window shows the agent-facing product surface that framing implies. Whether that framing is real or aspirational is not something this feed answers yet.

◆ Prediction

With the round announced around agent workloads, the next substantive release is most likely on that surface, though the entries here give no detail on what form it takes.

7.5

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

◆ Current state

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

◆ Where it's heading

Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.

◆ Prediction

Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
