CRM As A Business World Model: The Future For GTM Teams? | Keith Peiris, CEO @ Lightfield

Keith Peiris, Co-Founder and CEO of Lightfield, joins Sam Jacobs, AJ Bruno, and Asad Zaman to talk about building an agentic CRM that launched in November 2025, has been adopted by more than 5,000 customers, and just raised a $47 million Series A led by Andreessen Horowitz. Topics include why every system of record was really a forecasting tool, how to get reliable output from non-deterministic models, and the two reasons companies actually rip out Salesforce or HubSpot. Plus, a spirited debate on whether the SaaS partner ecosystem is dead, why AI-native deal sizes at 200-person companies can rival enterprise contracts, and how Lightfield landed on a mix of seat-based and consumption pricing.   Key Takeaways:   - Plan for models that will always make some mistakes. Keith builds Lightfield on the assumption that models stay non-deterministic, and calls reliability "a harness problem" that they're making fantastic progress against. - Use LLMs for insight and plain code for arithmetic. When Asad asked whether auditing AI forecasts saves anyone any time, Keith described a one-time implementation where Lightfield's head of finance checked every formula: "We converted some things from prompts to real code, right? I don't want LLMs doing math. I want real code doing math." That got the dashboards 95% of the way there, leaving the models to flag which deals were on the cusp because of missing features or competition. - Slightly better AI output won't justify replacing a CRM. After several rip-and-replace projects off Salesforce and HubSpot, Keith said marginally better agentic emails are "not a good enough reason to change a system of record." The two reasons that do move customers are believing one model of the business improves every stage of the revenue funnel, with SDRs pulling real-time case studies from customer success, and higher-level scenario planning, where "the modeling really matters. The data completion really matters." - Put predictable work in the seat price and meter the work with visible ROI. Lightfield tried both extremes, and pure consumption backfired: "It's like going to a store where everything's really expensive, that our customers didn't touch anything." The seat and platform fee now covers the core CRM, call recording, and the data model, while pipeline generation, AI workflow automations, and scenario planning run on consumption, because "most revenue leaders, CEOs… have an uncapped budget for business intelligence."   Connect with the Hosts & Guests:   Host: Sam Jacobs, CEO at Pavilion - https://www.linkedin.com/in/samfjacobs/ Host: AJ Bruno, CEO at QuotaPath - https://www.linkedin.com/in/ajbruno3/ Host: Asad Zaman, CEO at STA - https://www.linkedin.com/in/azaman1/ Guest: Keith Peiris, Co-Founder & CEO at Lightfield - https://www.linkedin.com/in/keithpeiris/   Topline is more than a Podcast:   Subscribe to Topline Newsletter: https://toplinemedia.substack.com/ Check us out on YouTube for the #1 video podcast for founders, operators, and investors in B2B tech: https://www.joinpavilion.com/topline-podcast Join the free Topline Slack channel to connect with 600+ revenue leaders to keep the conversation going beyond the podcast: https://www.joinpavilion.com/topline-slack
