Quanta: Software That Makes Accountants 100x More Successful

February 27, 2025

It’s certainly an extraordinary time in technology right now. But innovation breakthroughs themselves don’t create great products and enduring companies. No, for those you need extraordinary founders and teams, too. Enter Helen Hastings and Quanta, the fastest accounting service for software companies.

The Quanta team is purpose built for this mission. Starting with Helen herself, who spent 5+ years at Affirm, building systems of record and an offline ledger for their accounting and finance teams. She’s joined by a team that has engineered financial systems at Stripe and Affirm, and led accounting teams at Notion and Intercom. They know what they’re building and who they’re building it for. They’ve started with a general ledger integrated into an AI powered accounting engine which allows customers to easily automate routing tasks.

The goals? Speed, reliability, and expertise (both built into the product and available to support customers as needed via Slack).

The impact? Before Quanta, their users didn't receive a draft of their books until, on average, more than 3 weeks after the month ended—and many days more to get them finalized. This means they didn't see January 1st data until around February 28th, and sometimes even longer. Now, users tell Quanta they use their up-to-date finances for strategic purposes multiple times a week.

The startup has been quietly building for a core set of customers over the past quarters and today is announcing its $4.7 million seed round, which Homebrew was fortunate to participate in.

If you think Quanta might help your software company, you can now check them out - early stage companies should be able to onboard and get a quick draft of their finances, easily and 24/7.

And if a company like Quanta sounds like where you want to continue your professional career, they’re hiring.
