Profile Bio

Cal Henderson’s Age and Background

Cal Henderson was born Callum James Henderson-Begg on 17 January 1981 in Bedfordshire, England, which makes him 45 in 2026. He began programming as a child on a TI-99 computer. He earned a software engineering degree from Birmingham City University in 2002, worked at the publisher Emap, then became the first person hired at Flickr.

Cal Henderson’s Career

After Flickr’s sale to Yahoo!, Henderson moved to San Francisco. In 2009 he joined Stewart Butterfield at Tiny Speck to build the online game Glitch. The game failed, but its internal chat tool became Slack, which launched in 2013. As CTO, Henderson helped scale the product until Salesforce bought it in 2021 for $27.7 billion.

Why Henderson Left Slack

Henderson stepped down as Slack’s CTO in mid-January 2024, and Salesforce co-founder Parker Harris took over engineering. A Salesforce spokesperson noted that founders rarely stay as long after an acquisition as he did. He also wrote Building Scalable Websites and helped create the basis for OAuth and oEmbed.

Henderson’s Family and Giving

Henderson is married to Rebecca and lives in San Francisco. Through the Henderson Family Foundation, the couple gave Birmingham City University $500,000 for a pilot program, then $2.75 million to expand it. The program targets under-representation in UK technology and engineering. Reliable details about his children and siblings aren’t public, so they’re left out.

Henderson’s Net Worth, Height and Social Media

Henderson’s net worth isn’t confirmed. In 2019, when Slack was valued at $13 billion, his stake was estimated at $442 million, but that is an old paper figure. No reliable source gives his height. He keeps a personal blog at iamcal.com and has LinkedIn and X profiles.

Ryan Lance’s Age and Early Life

Ryan Lance was born on 21 May 1962 in Blytheville, Arkansas, and is 64. He grew up in Great Falls, Montana, and paid for college by working on oil rigs in Wyoming. He graduated from Montana Technological University in 1984 with a petroleum engineering degree. That hands-on start shaped the rest of his career.

Ryan Lance’s Career

Lance joined ARCO Alaska in 1984 and later worked in California, Texas and Houston. After Conoco and Phillips merged in 2002, he moved up through technology, major projects and international operations. He became chairman and CEO of ConocoPhillips in May 2012 and led the company for 14 years.

The 2026 Leadership Handover

On 6 August 2026, ConocoPhillips announced that CFO Andy O’Brien would succeed Lance as president and CEO. On 1 September, Lance became executive chair in a transitional role. The board thanked him for more than 40 years of service. His 2027 long-term incentive target drops to $12.4 million.

Lance’s Family and Giving

Lance and his wife, Lisa, have two children. In 2023 they gave Montana Tech $31 million, the largest gift in its history. It funds the Lance Scholars program and an endowed energy chair. The School of Mines & Engineering became the Lance College of Mines & Engineering, and the university announced an honorary doctorate for him in 2026.

Lance’s Net Worth, Height and Social Media

Lance’s net worth hasn’t been disclosed. One data aggregator lists total yearly compensation near $23.45 million and direct holdings around $39.6 million, but neither figure equals net worth. No reliable source gives his height, and I found no official personal social accounts. Most information comes from company filings.

Henderson vs. Lance: Key Differences

Henderson built a company from scratch and sold it. Lance rose over four decades inside an established one. Software can ship overnight, while energy projects take years and heavy capital. Henderson’s wealth is tied to company ownership, while Lance’s comes mostly from executive pay and stock awards.

What They Have in Common

Both are trained engineers who stayed close to technical work before leading large organizations. Both returned to their universities with major gifts. They aren’t related, and no known business partnership connects them, so the link is a similar career style rather than a shared history.

Fun Facts

Henderson is colour blind and has built web accessibility tools. Lance worked as a roughneck before becoming CEO. A college at Montana Tech carries Lance’s name, and Birmingham City University gave Henderson an honorary doctorate in 2019.

Final Thoughts

Cal Henderson and Ryan Lance took very different routes to the top. Henderson built Slack from a failed game and later stepped away from it. Lance spent four decades at one company before moving to executive chair in 2026. They aren’t connected, but both prove that strong technical roots can lead to major leadership roles.
