What is Gumloop?
Gumloop is turning its whole connector catalog into agent memory, one week at a time.
Gumloop launched Company Brain in early July and has widened it on almost every release since — Zendesk as a source, then permission-preserving Google Drive, then any connector in the catalog at all. The agent layer is picking up its own plumbing in parallel: organization skills sync from a GitHub repository and update as commits land, skills and connectors are manageable through the developer API (including by other agents), and agents can be DM'd directly in Slack. Models rotate through continuously, with Claude Opus 5 and Kimi K3 the latest, alongside bring-your-own Fireworks keys for running open models on a customer's own account.
What is Sulu?
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.
Gumloop vs Sulu: editorial side-by-side
Gumloop
7.5MKT AUTO
Gumloop is turning its whole connector catalog into agent memory, one week at a time.
◆ Current state
Gumloop launched Company Brain in early July and has widened it on almost every release since — Zendesk as a source, then permission-preserving Google Drive, then any connector in the catalog at all. The agent layer is picking up its own plumbing in parallel: organization skills sync from a GitHub repository and update as commits land, skills and connectors are manageable through the developer API (including by other agents), and agents can be DM'd directly in Slack. Models rotate through continuously, with Claude Opus 5 and Kimi K3 the latest, alongside bring-your-own Fireworks keys for running open models on a customer's own account.
◆ Where it's heading
Two loops are closing at once. On knowledge, every connector Gumloop adds now doubles as a retrieval source, so catalog growth and Brain quality compound instead of competing for roadmap. On capability, skills are becoming versioned artifacts that live in a repository and agents are becoming things other agents can configure through the API — the platform is moving from a place you build one agent to a place agents are provisioned programmatically. Governance is following a step behind rather than leading: audit logs for Brain activity, access requests routed to approvers, per-conversation credit breakdowns, and usage-based billing for workflow AI steps.
◆ Prediction
Expect the same generalization that took Brain from fixed sources to any connector to be applied to triggers and actions, and expect the agent-configures-agent API to grow into templated provisioning so organizations can stamp out fleets rather than assemble agents one at a time.
Sulu
5.0MKT AUTO
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
◆ Current state
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.
◆ Where it's heading
Three threads run through the pairs. Editor upkeep is constant, with CKEditor moving to 47 LTS and then 48 and the fallout — table widgets, webpack font builds — fixed release by release. Framework compatibility is the second: Request->get calls replaced for Symfony 8, PHPUnit 13 and PHPStan kept green on lowest dependencies. The third and most interesting is data-model cleanup on the 3.0 side, where tags migrated from names to IDs behind a newly added DoctrineMigrationsBundle, with smart-content filters reworked to match. What is not visible is any capability that exists on 3.0 and not on 2.6 — a major version that is not yet behaving like one.
◆ Prediction
Expect the paired-release rhythm to continue with more Symfony 8 preparation and CKEditor 48 fallout. The open question is when 3.0 starts receiving work that is not upmerged from 2.6; until then the major version number is not buying users anything.
