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 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

Convex
2.5DEVOPS
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.
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
