Noded AI

Noded is the Customer Context Graph - the system of action for everything that happens after the sale. 70% of revenue is post-sale, but there's never been a system of action for it. Your customer's story is scattered across 20+ tools - Salesforce, Slack, Gong, Zendesk, Jira, Gmail, and more. Pre-sales CRMs only ever saw part of it. Legacy customer success platforms rot the moment your team stops feeding them and take 12–18 months and a dedicated admin to stand up. So the people who own retention and growth act on incomplete information - and do it by hand. Noded fixes the foundation. Instead of a year-long data-cleanup project, it finds the high-intention, high-impact data - the data that got the work done - and weaves every account into one living story, automatically. No fields to fill. No dashboard to maintain. The picture assembles itself. What you can do with Noded: 1. Walk into every meeting already caught up - one shared, always-current view of each account: "the Notion page you don't have to maintain." Deeper insight is one question away. 2. Spot churn while you can still fix it - Noded watches the signals that actually precede churn (inbound going quiet, champions going dark) and flags risk months before the renewal call. Turn a 72-hour emergency into a 180-day plan. 3. Catch expansion the moment it surfaces - a new team, integration, or initiative mentioned anywhere becomes a qualified play, with humans and agents aligned behind your motion to drive 25–40% more growth. 4. Research any account in your favorite LLM - ChatGPT, Claude, and Gemini connected to your full customer stack, so research starts from the whole story, not a blank prompt. Spend your time engaging, not drafting - ask @noded in Slack and the QBR deck, briefing doc, or account review drafts itself from the live account story, cutting prep time 80–90%. 5. It updates your tools, not the other way round - Noded posts to Slack, updates Salesforce fields, and files the Linear ticket, inside the tools your team already lives in. Why teams switch - three things nothing else does together: 6. The whole story, automatically. Built from the data that got it done, not everything - no admin. 7. Learned, not implemented. Agents learn your playbooks by watching real work. No workflow mapping, no rollout project. 8. Acts where you work. Slack, Salesforce, Linear, Claude - Noded surfaces the next step and takes it, not one more tab. Enterprise-ready, and fast. SOC 2 audited. Noded never trains on your data and stores nothing with LLM providers. It connects as you and works within your existing permissions. Time to value is a coffee break - no migration, no IT project, no data cleanup required. Built by the team behind Salesforce Flow, the Slack Platform, and Boomi - $30B+ across four exits - now reinventing the system of action for the customer.

Phano

Phano is a composite AI for Customer Success and Account Management teams. Every day it crosses each account's signals (usage, relationship, support and every other source you connect) to surface, ahead of renewal, the accounts at risk of churn and the ones ready for expansion, with the probable cause and the recommended action. Phano also covers client meetings: a full brief before every call, live coaching during it, a structured recap written to the CRM record after, and the follow-up email drafted in your inbox. Intelligence is delivered where your team already works: phano_* field enrichment in your CRM, email digests, Slack, Microsoft Teams, webhooks, plus API and MCP access. Specialized agents handle each diagnostic so the CSM protects the install base and the Account Manager grows it, from the same diagnostic. Getting started is self-serve: create a workspace at https://phano.ai, connect a data source (HubSpot, Salesforce, Pipedrive and more), and the first diagnostics arrive the same day. 30-day trial, no credit card required.

Routeability

Most companies run sales in one tool and customer success in another, and the outcome a customer was sold gets lost in the handoff. Routeability removes that gap. It manages the entire customer relationship end to end, from the first opportunity to renewal and expansion, on one continuous record. The qualification an AE did, the outcome the proposal promised, and the value the customer actually needs all carry forward, so the team delivering is working from the same truth the team that sold it created. Pre-sale and sales. Capture inbound leads, work prospects through a pipeline, and forecast with confidence. Lead capture and an inbound inbox Prospect and opportunity pipeline with stages Sales forecasting with pipeline, best-case, and commit categories, by rep Proposals with discounts and tax handling MEDDPICC-based account qualification Quota and coverage, pipeline health, and forecast accuracy analytics Owners (AE, SE, CSM), teams, territories, and opportunity splits The handoff, solved. A prospect becomes a customer on the same record. Closing a deal carries the account, its qualification, and its committed outcome straight into onboarding. Nothing is re-keyed and nothing is lost. Post-sale and customer success. Turn a signed contract into proven, renewable value. Health scoring tied to adoption and outcomes, so risk surfaces early Renewals with weighted ARR-at-risk forecasting and risk tiers Expansion pipeline, forecast like new business Executive business review and QBR tracking against account objectives Account qualification that continues to live after the sale Revenue intelligence across the whole lifecycle. ARR, GRR, and NRR reporting built on an immutable financial ledger, with fiscal-year analytics and forecast categories, so new business, retention, and expansion are all measured on one consistent set of numbers. A diagnostic-led partnership, not just a login. Most platforms hand you an empty tool and wish you luck. Routeability starts with a diagnostic of your post-sale motion that maps the real journey from signed contract to proven value and shows where deployments stall, where adoption fades, and where renewals are quietly at risk. From there, senior consulting redesigns the motion through journey mapping, a common taxonomy, adoption strategy, and AI and automation, and the platform operationalizes and sustains it. You diagnose, design, and operate in one place, with people who have done it, not a self-serve tool you have to figure out alone. AI that assists, not replaces. Routeability’s AI agents draft the next best action, such as a renewal-risk play or an expansion opportunity, and route it to a human to approve. Every action is logged and auditable. Nothing happens to a customer without a person deciding. Built for teams that handle real data. Multi-workspace support, role-based access, enforced MFA, optional SAML single sign-on, and strict tenant isolation enforced at the database layer. How Routeability is different. Most teams end up with two systems: a sales CRM like Salesforce or HubSpot, and a separate customer success tool like Gainsight, Catalyst, or ChurnZero bolted onto it. That split is exactly where the outcome a customer was sold gets lost, because the handoff is a data transfer between tools instead of a continuous relationship. Routeability is built the other way around. Pre-sale and post-sale live on one record, so qualification, the committed outcome, health, renewals, and expansion are all the same account history rather than two halves stitched together. Revenue is measured on one ledger from first pipeline dollar to net revenue retention, instead of reconciled across systems. And where legacy platforms price per seat, treat AI as a costly add-on, and leave implementation to you, Routeability is priced per workspace with unlimited users and AI included, and every engagement begins with a diagnostic and the expertise to act on it. The result is a single source of truth for the entire customer relationship, delivered as a partnership, not a sales tool and a success tool pretending to talk to each other. Routeability is for SaaS teams that want one platform for the entire customer relationship, where the outcome sold is the outcome delivered, and leadership can see revenue from first pipeline dollar to net revenue retention.
