How it works

The gist

Takes a company's last funding date (from Attio / PitchBook), standardizes it against today's date, and returns a router decision telling the next Zap step which outreach template to send:

congrats — they raised in the last ~2 months. Send the "congrats on the raise" outreach.
normal — otherwise. Send the standard intro email.

The flow

Inputs — lastfundingdate (e.g. "2025-02-21") and todaydate (ISO from Zapier), via inputData in a "Run JavaScript" step.
Standardize. Both strings get parsed into real Date objects so downstream math is correct regardless of whether the input had a time component.
Compute the gap in months using an average-month constant (30.44 days), which is good enough for a 2-month cutoff.
Return { outreach_type }. Branch the Zap on it — one path drafts the congrats note, the other drafts the standard intro.

Why this exists

Reaching out cold five days after a founder closes a round is a different conversation than reaching out cold five months later. This is the one-liner that picks the right opening for you so you stop sending generic intros to founders who just raised.

const lastFunding = inputData.lastfundingdate; // e.g. "2025-02-21"
const todayRaw = inputData.todaydate;          // ISO format from Zapier

// Parse both dates — handle ISO with or without time component

const diffDays = diffMs / (1000 * 60 * 60 * 24);
const diffMonths = diffDays / 30.44; // average days per month

const result = diffMonths <= 2 ? "congrats" : "normal";

return { outreach_type: result };
