What is Gumloop?

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

What is Lemlist?

Lemlist ships domain purchasing, real-time lead scoring, and phone enrichment — the cold-email tool is becoming infrastructure.

Lemlist has shipped a meaningful cluster of capabilities over this period: users can now buy Google domains and email addresses directly within the platform, enrich contact phone numbers through a Cleon1-backed waterfall, score leads in real time, and manage all team sending accounts from a single settings panel. The product has moved beyond sequencing into managing the underlying outreach stack.

7.5

Gumloop 13.1 lets live artifacts drive agents through the SDK and opens outputs in Office.

◆ Current state

Gumloop ships a numbered release every few days. In October it gave agents a real browser (12.0), agent-owned secrets, team sharing and embeddable AI artifacts, then 13.0 rebuilt the agent harness for longer work and added organization-wide evaluations. 13.1 lets scripts in live artifacts message, create and list agents, artifacts, skills and teams through the Gumloop SDK, opens agent-made files in Google Workspace or Microsoft Office, and lets agents on a call run long tasks in the background while they keep talking.

◆ Where it's heading

The product is moving from building agents to operating them at org scale, and artifacts are turning into small apps that can control agents themselves. Model access is also being made easier to manage, with families, deprecation dates and fallback visibility.

◆ Prediction

Expect more of the SDK exposed to artifacts and further evaluation and Insights controls at the usual weekly pace; the entries don't show pricing changes.

0.0

Lemlist ships domain purchasing, real-time lead scoring, and phone enrichment — the cold-email tool is becoming infrastructure.

◆ Current state

Lemlist has shipped a meaningful cluster of capabilities over this period: users can now buy Google domains and email addresses directly within the platform, enrich contact phone numbers through a Cleon1-backed waterfall, score leads in real time, and manage all team sending accounts from a single settings panel. The product has moved beyond sequencing into managing the underlying outreach stack.

◆ Where it's heading

Lemlist is consolidating the tool sprawl that surrounds cold outreach — enrichment, domain management, infrastructure, and engagement scoring are being pulled in-house. Each release reduces the number of external services a sales team needs alongside lemlist. The long-term bet is a closed loop: buy domain, warm it, enrich leads, sequence, score, convert — without leaving the platform.

◆ Prediction

The next likely move is either deeper enrichment coverage (adding data providers beyond Cleon1) or a unified reply inbox that pulls LinkedIn, email, and phone responses into a single thread, completing the multi-channel loop.
