About This Episode
In EP010, Jay Nathan and Jeff Breunsbach dig into the foundational data problem most SaaS teams are still ignoring — and why it's about to become a serious competitive liability. Jeff opens with a concrete example from Junction: their Head of Data and AI is pulling together support tickets, invoice data, CRM records, and product usage into a unified layer in BigQuery and Metabase, creating the infrastructure needed to actually build AI agents that can serve CSMs in real time.
Jay expands the lens. He's been talking to companies all week — from 150-person startups to 3,500-person enterprises — and the story is identical across all of them: they don't know who their customer is. Six Salesforce instances. Years away from consolidation. His prescription is clear: stop waiting on the CRM roadmap. Build a customer master record outside of it now, with a data layer your AI tools can actually connect to.
The second half gets into "Company as Code" — Jay's emerging practice of documenting personas, ICP definitions, and outreach styles as markdown files stored in a GitHub repo. One canonical source of truth, updated via pull request. And once that foundation exists, the personalization flywheel kicks in fast: Jay's son Jack built personalized landing pages and interactive click-through surveys in a single afternoon. The same playbook, Jay argues, belongs just as much in customer success as it does in prospecting.
Key Takeaways
Build the customer master record before you build anything else. Jay spoke with companies ranging from 150 to 3,500 employees this week and heard the same story at every size: siloed data, duplicate records, and no unified view of who the customer actually is. His prescription — don't wait for the multi-year CRM consolidation. Build a deduplicated customer master outside your CRM now, with pointers to every system where customer data lives.
Company as Code. Jay is storing his company's personas, ICP definitions, and outreach templates as markdown files in GitHub — one repo, one source of truth, updated by anyone via pull request. The key insight: historically a persona lived in a slide deck that the CS team read once and interpreted their own way. Now every tool and every team pulls from the same canonical definition.
Siloed AI is just siloed data with a new wrapper. Jeff makes the point directly: if your sales AI only sees sales data and your CS AI only sees CS data, you've recreated your data silos with an AI layer on top. The only real fix is fixing the data layer first — before the agents, before the automations.
Personalization is now just token costs. Custom landing pages, hyper-personalized emails, interactive qualification surveys — these used to require significant investment. Now the constraint is building the right markdown files and personas. Jay and Jack built a fully personalized, interactive landing page workflow in a single afternoon.
Treat your customers like prospects. Just because someone is a customer doesn't mean they understand your product or know your full offering. Jay makes the case for using the same outbound personalization playbook — custom pages, targeted messaging, value reminders — to re-engage and educate the customer base. It's dramatically cheaper than it used to be.
ABM belongs in Customer Success. Jay shares the "Spreading the FLU" story — a field-level understanding program from a prior company that systematically worked through every influencer at every top account. CS teams should be running the same play for their top 10–20% of revenue-generating customers. Most aren't.
AI-powered upsell prioritization. Jeff describes using Fathom call recordings, emails, and Slack signals to surface the top 10–20 customers most likely to need a new product — before sending a rep in cold. The idea: let AI do the signal-reading so CS can show up with context, not guesses.
The CSP question is getting real. Jay is hosting a webinar this week — "It's 2026. Do you need a customer success platform anymore?" — featuring Miranda Decowski (a three-time CSP customer) and Ziv Pellid (who built everything in-house). Jay's own take: "I don't need multiple CRMs. That's the antithesis of everything we just talked about."
