A unified memory layer for your company. Sentra captures every interaction, decision, and drift, and writes it into one queryable graph your team and your agents share.
Vector search returns what’s close, not what’s correct. Sentra resolves semantics at ingestion and builds the graph on demand at query time, against an ontology unique to your organization. The category is having a moment. The architecture is what produces comprehension.
Embeddings stored at write. Structure guessed at query time. Every request crawls Slack, email, and docs to rediscover what something means.
Semantics resolved at ingestion. The graph is constructed on demand at query time, against a per-organization ontology. Meaning is a primitive, not a side effect.
Pulls the CRM record, the Jira ticket, the Confluence page. You get the output of a decision, never the decision.
Captures meetings, threads, emails, calls, agent traces as first-class evidence. The why travels with the what.
Sarah Chen in HubSpot, S. Chen in Gmail, @schen in Slack read as three different people. Context never joins up.
Continuous, confidence-scored identity resolution across names, emails, handles, phone numbers, and internal IDs.
A flat haystack of embeddings. Old facts sit next to new ones, equally weighted, ready to restate yesterday as today.
Every fact carries when it became true and when it stopped. Old facts are invalidated, not deleted. Provenance is first-class.
Factual, action, interaction. Three coordinated layers capture what is true, what is owed, and what was meant. Every answer is grounded in the full context of the company.
Sentra is the only system above 30% on both Cascade and Absence, the two tasks the MEME benchmark (KAIST, 2026) identifies as unsolved at practical cost. The field averages 3% on Cascade and 1% on Absence. Most memory systems can store facts. They can’t reason about what changes when those facts update.

200+ tools and counting.
View all integrationsNo new system to manage. Sentra listens to the tools you already use, remembers everything, and tells the right people what matters next.
Your CRM knows the deal changed. Sentra knows the customer escalated, who approved the exception, and which tradeoff made the decision make sense.
Commitments do not wait for someone to write them down. Sentra tracks them from the moment they are spoken and keeps the evidence attached.
Most tools tell you what is loud. Sentra surfaces what has gone stale, what is at risk, and what has not been mentioned in two weeks.
Weekly reviews, prep briefs, customer histories, and project status come from the same graph. No chasing people. No reconstructing context.
Every team has its own view of the truth. Engineering reads code. Sales reads deals. Finance reads numbers. Sentra connects every perspective into one company brain.
“Why did we ship without the burst window?”
The burst window was cut on Apr 8 after a Redis race surfaced. The decision moved to PR #4128 with a TODO to revisit in v1.1.
“Why did we lose the Northwind deal?”
Churned on procurement timing, not product. Legal verbally agreed to a 60-day MSA exception on Feb 27 — never written down.
“Why is Q1 burn 14% over plan?”
The AWS reserved-instance cutover slipped three weeks past Mar 1. Drift was logged Mar 18; finance was looped in on Mar 22.
“What did we promise design partners?”
Six commitments across four partners. Four shipped, one slipped (SAML SSO for Acme), one quietly dropped.
“What did we promise Maya for promo?”
Two specifics: a written calibration target by end of Q2, and a stretch project tied to the platform rewrite.
“Have we ever granted uncapped indemnity?”
Twice. Both pre-Series A, both signed by Ashwin, both flagged in the Feb 2025 audit. Policy now requires a written exception.
“What's changed since the last board?”
Nine material decisions, three reversals, two unfulfilled commitments. Reversals concentrated in pricing.
