Whalesync

Whalesync (legal entity Whaleform Inc.) offers a no-code integration product that creates true two-way synchronization between spreadsheet-style tools — Airtable, Notion and Google Sheets — and vertical SaaS applications including Webflow, Wix CMS, WordPress, HubSpot, Salesforce, Pipedrive, Attio, Affinity, Stripe, Memberstack, Supabase and Postgres. A change made in either connected tool propagates to the other, including linked/multi-reference records, images and rich text. Setup consists of three steps: connecting the apps, mapping tables and fields, and turning sync on.

Product capabilities include real-time and historical sync, record matching on a primary key, advanced filters, smart API limits, bulk update handling, auto-create tables, a Live Export feature, and monitoring views for syncs, issues and individual operations, with AI-summarized error explanations and full API responses for troubleshooting. Developer-facing surfaces include an API, an MCP server and an agent quickstart. Enterprise features cited by the company include SOC 2 Type II, GDPR compliance, encryption at rest monitored by Vanta, SSO via OAuth, role-based access control, versioning and dedicated support.

Common documented use cases are generating large volumes of programmatic SEO pages in Webflow from Airtable, tracking or enriching CRM deals and leads from Notion or Google Sheets (HubSpot, Salesforce, Affinity), building internal tools and admin panels over Supabase or Postgres from Airtable, and syncing Notion with Google Sheets so teams and clients can work in familiar tools.

Founding story

According to the founders, Whalesync was launched out of Y Combinator's Summer 2021 batch after operators described the difficulty of connecting the website builder Webflow with the spreadsheet tool Airtable. As the founders spoke with more builders, they found the same problem across other tool pairs — sales reps exporting CSVs from Sheets into Salesforce, developers attempting Postgres-to-Airtable integrations, and investors wanting to control Affinity from Notion — and broadened the product into a general spreadsheet-to-SaaS sync platform. The company frames its thesis around the continued dominance of spreadsheets (Google Sheets, Notion, Airtable) as flexible, low-learning-curve bulk editing surfaces that cannot replicate the specialized functionality of vertical SaaS applications.

Business model

Software-as-a-service sold by self-serve subscription with a seven-day free trial, tiered by which connectors are included and how many records are kept in sync; larger deployments (beyond 50,000 records) are handled through a sales demo, and an enterprise tier adds security assessment, custom agreements, SSO and dedicated support.

Recurring subscription fees with monthly or yearly billing (yearly billing discounted up to 20%). Published tiers are Starter at $40/month (1,000 records in sync, ten connectors), Plus (adds Attio, HubSpot, Pipedrive) and Pro (all connectors, including Affinity and Salesforce), with Plus and Pro supporting up to 1,000,000 records in sync. Mappings, row changes and active syncs are unlimited on all plans; a 20% nonprofit discount is offered.

Traction

The company reports hundreds of companies as customers — naming Webflow, Ramp, Alchemy, Descript and Clay — and states it processes millions of transactions per day. Its Y Combinator profile lists a team size of 8. A large volume of user testimonials from 2022-era members is published on the website.

Latest developments

Recent activity includes a launch positioning Whalesync as giving spreadsheets edit access to app data for bulk editing, collaboration and AI workflows, the addition of an MCP server and agent quickstart for programmatic and AI-agent access, AI-summarized issue guidance in the monitoring interface, a Live Export feature, and the launch of an AI tools directory of 1,000 tools on Product Hunt.
