Thatch hits $1B valuation after $108M round from existing backers

Health benefits startup Thatch has raised $108 million in new funding at a $1 billion valuation, backed by existing investors including Andreessen Horowitz, General Catalyst, Index Ventures, and The General Partnership.

Fixing One Bottleneck Doesn't Fix the Underlying Conflict, Warns Business Coach

An Entrepreneur contributor describes a COO who resolved a six-week product launch delay caused by slow procurement approval on packaging spec changes by setting a spending cap for same-day approval of urgent vendor fees. The next launch hit its date, proving the fix worked for that specific request, but the piece argues this success can mask a deeper, recurring tension between speed and financial oversight that will resurface elsewhere.

Entrepreneur op-ed urges founders to audit tasks before adding headcount

A contributor column advises business owners to list the ten recurring tasks a proposed hire would actually perform and sort them into judgment, relationship, repetition and coordination categories before approving a new position. The piece argues that hiring is often a default response to growth, even when the real bottleneck is a broken workflow rather than a lack of people. It cites Census Bureau data showing only about 17-20% of businesses use AI, with Sales, Strategy and IT as top adopting functions where automation could resolve repetitive work.

Benchmark shows subnormal floating-point math slows Intel Xeon chips far more than AMD or Arm rivals

A developer benchmarked how Intel, AMD, Arm and Apple processors handle IEEE 754 subnormal floating-point numbers—the tiny values near zero that require special handling. Testing double-precision arithmetic on Intel Granite Rapids and Emerald Rapids Xeons, AMD Zen 5, AWS Graviton, and Apple M4 Max chips, the results showed Intel processors suffer dramatic slowdowns, sometimes 40-plus times slower, when computations involve subnormal values compared to normal ones.

Study Highlights Malloc() Bottlenecks in Multithreaded Programs

An analysis traces the evolution of memory allocation from stack-based schemes to dynamic linked-list heaps, garbage collection, and jemalloc's 2006 introduction of 'arenas' for NUMA and multi-core memory management. It notes that standard malloc() implementations serialize concurrent allocation requests, causing multithreaded applications to slow down rather than scale as processor counts increase.
