Should Salesforce sell off Slack?

📖 1,081 words⏱ 5 min read5/2/2026

Direct Answer

Sell Slack. Not immediately, but within 18 months. The $27.7B acquisition (July 2021) has become a balance-sheet anchor and activist pressure point—Slack's valuation has compressed 65% to ~$8–12B.

The M&A math is inarguable: a $15–20B writedown crystallizes *now*, or you bleed it over 5 years. More important: Slack-as-a-standalone is not a defensible enterprise workflow platform anymore. Microsoft Teams, Google Workspace, and native AI integrations have commoditized workplace chat.

Salesforce's Agentforce momentum is real, but layering it *through* Slack is execution theatre. Sell to a PE buyer (Vista, Thoma Bravo, Silver Lake), lock in 4–5x EBITDA, return $9–11B to shareholders, and fund Agentforce + Core CRM innovation.

Four Specific Moves

  1. Engage Centerview Partners now (independent M&A shop, not conflicted with banker relationships) to model buyer pool and conduct confidential market test Q2–Q3 2026.
  2. Position Slack for margin punch: 10% opex cuts, transition to SaaS-hygiene GAAP model (kill Slack Ventures, pare international teams), show potential buyer a 40%+ EBITDA path.
  3. Credible buyer list: Vista (workflow SaaS portfolio), Thoma Bravo (mature SaaS roll-up thesis), Silver Lake (enterprise software + strategic angle), Automattic (long-shot: they own WordPress + WooCommerce, value open integrations).
  4. Messaging: Frame as "strategic focus" on Core CRM and Agentforce. Don't say "distressed." Say "Slack's highest-and-best-use is under specialist ownership where workflow-native product dev is the north star."

The Case For Selling

The Case For Keeping

What Salesforce Should Actually Do

  1. Model the Slack divestiture decision as a 3-scenario CFO exercise (sell FY25 vs. sell FY26 vs. hold-through-2027). Centerview or Goldman Sachs M&A should run the buyer-expectation analysis.
  2. If you're keeping Slack, commit to agentic-workflow execution. Announce a $500M integration roadmap: channel-as-API for Agentforce, Slack as the orchestration layer for sales process. Make it real, not PR.
  3. If you're selling, announce buyer pool and timeline today. Don't leak; don't drag. Confidence kills activist chatter. "We're engaging with strategic and financial buyers. Expect process update in Q3." Transparency wins.
  4. Engage Klue and Force Management to map buyer thesis for each PE firm. Vista wants SaaS roll-ups (show consolidation upside). Thoma Bravo wants 40%+ EBITDA (show the path). Positioning *per buyer* beats generic auction.
  5. Cut Slack opex 10% in H1 2026. Kill the venture fund, consolidate international hubs, right-size product org. Show buyers a disciplined business, not a cost center.
  6. Use Pavilion data (2,000+ B2B go-to-market leaders in network) to stress-test the "Slack is core to sales workflow" narrative. Survey: would you *leave Salesforce CRM* if Slack was spun out? Likely answer: no. This kills internal hold-out arguments.
  7. Benchmark against Microsoft's Team divestiture decision circa 2016 (they kept Teams, made it *the* enterprise chat layer). Ask: why Microsoft succeeded (product monopoly + distribution) but Salesforce won't (no distribution monopoly + chat commoditized).
  8. Board decision gate: Q2 2026. Either commit to agentic-Slack execution (genuine $500M bet) or run the sale process. Straddling is the costliest option.

Bottom Line

The Slack decision isn't "M&A or not." It's CFO discipline vs. founder attachment. Benioff paid $27.7B for a vision (enterprise workflow + CRM). That vision hasn't materialized; chat commoditized faster.

A disciplined CFO sells in H2 2026 to a PE firm (Vista, Thoma Bravo), returns $10B to shareholders, and tells the story: "Slack's highest-and-best-use is under ownership where product-innovation velocity is mission-critical." A founder-led board holds and bets Agentforce will unlock a 2028–2029 upside.

Both are defensible; straddling until 2027 is not.
