Inflection

Inflection (inflection.io) is a Seattle-headquartered B2B marketing automation company that positions its platform as a replacement for legacy marketing automation platforms such as Marketo. The product combines AI agents with human marketers to draft campaigns, map journeys, produce CMO reporting, score accounts and build segments, using first-party context drawn from a customer's website, CRM and product usage data. The company frames its scope as "full lifecycle" marketing spanning acquisition, product onboarding, adoption, expansion and advocacy, rather than the lead and MQL management focus it attributes to platforms designed in the mid-2000s.

Capabilities described by the company include building complete campaigns from a prompt, saving reusable "AI skills" for recurring campaigns such as newsletters and announcements, AI-generated 1:1 personalized emails using first-party signals (page views, email opens, Salesforce or data warehouse fields), triggered and batch email execution from a single journey canvas, a token builder for personalization, forms workflows via a forms API and integrations with Webflow and Formstack, and account scoring and ICP list building based on its acquisition of Keyplay. Infrastructure features include bi-directional native Salesforce sync covering leads, contacts, opportunities, campaigns and accounts, zero-ETL integration with CDPs and data warehouses, inbound and outbound webhooks, a product data explorer, inflection.js web tracking, attribution tied to Salesforce campaigns, an account–user–org B2B data model, administrative agents for marketing operations teams, and an API the company says has no formal daily limits. Agent access is offered in-app and through Slack, Claude and ChatGPT apps, and an MCP server. The company also offers an AI-assisted Marketo migration agent that scans a Marketo instance, documents its logic and rebuilds it in Inflection.

Founding story

Inflection was founded in 2021 by Aaron Bird together with former colleagues Dave Rigotti and Vic Davis; the three previously worked at Bizible, which Bird also founded and which was acquired by Marketo in 2018 before Marketo became part of Adobe. The company describes itself as run by operators with more than 15 years of building marketing technology, with many team members having previously worked together at Bizible and Marketo.

Business model

Software platform sold to B2B marketing organizations, with go-to-market centered on demo requests and displacement of incumbent marketing automation platforms.

Traction

The company reported 32 employees and $14 million in total funding as of December 2024, declined to disclose revenue metrics, and said it expected to become cash flow positive without additional funding. Published customer case study figures cite over $100,000 in savings and more than 1,000 manual hours cut, a 28% increase in product logins from Inflection emails, and a 126% increase in user reactivation. The site lists customers including Twilio, Mural, Amplitude, BILL and Clay.

Latest developments

In December 2024 Inflection confirmed a $7.6 million raise from existing investors. It has since acquired Keyplay and integrated account scoring into the platform, and markets AI agents, reusable AI skills and AI-assisted Marketo migrations. CEO Aaron Bird is listed as a speaker at Startup Day 2026 in Seattle.
