Lasse Kalkar

Co-Founder & CEO LiveFlow

Last Reviewed: September 19, 2026

Executive Summary

Lasse Kalkar is the co-founder and Chief Executive Officer of LiveFlow, a Y Combinator-backed platform that connects accounting systems to live spreadsheets so that financial reports update themselves. The problem it removes is universal and rarely questioned: every month, finance teams export data from their accounting system, paste it into a spreadsheet, rebuild the same reports, and discover the errors later. Finance people live in spreadsheets because spreadsheets are flexible, and no amount of reporting functionality inside an accounting package has changed that — so LiveFlow made the spreadsheet live rather than trying to replace it. Kalkar co-founded the company with Anita Koimur, a fellow Revolut alumnus, having previously run Nordic growth there.

Career Highlights

• Co-founded LiveFlow with Anita Koimur and leads it as CEO.
• Took the company through Y Combinator, and has since positioned it as a unified AI-ERP and FP&A platform.
• Ran growth for the Nordic markets at Revolut during its European expansion.
• Worked at Nova Founders Capital, a London venture capital firm and startup studio.
• Previously founded and led Satochi, a robo-advisory investing application for cryptocurrency.

Professional Journey

Kalkar’s career has run through fintech from several angles. He founded Satochi, a robo-advisory investing app for cryptocurrency, an early attempt at bringing automated portfolio management to an asset class that then had almost no such infrastructure. He worked at Nova Founders Capital, a London-based venture capital firm and startup studio, which is an unusual vantage point in that the model involves building companies rather than only funding them.

He then joined Revolut as Head of Growth for the Nordics, during the period when the company was expanding aggressively across European markets. Revolut’s growth function in that era was notably quantitative and fast-moving, and it is also where he met Anita Koimur, who worked in rewards and business development and who became his co-founder.

LiveFlow came out of an observation about how finance work actually happens. Accounting systems hold the data; spreadsheets are where finance teams think. Every reporting cycle involves manually moving the former into the latter, and every manual move introduces the possibility of a stale figure or a broken formula that nobody notices until a board meeting. Rather than arguing that finance teams should abandon spreadsheets — an argument the software industry has lost repeatedly for four decades — LiveFlow connects accounting data into the spreadsheet as a live feed, so the models finance teams have already built stay current on their own.

The company went through Y Combinator and has since broadened its positioning toward a unified AI-ERP and FP&A platform, extending from reporting into planning and close automation. Kalkar leads it as Chief Executive Officer.
