๐Ÿ’ธ Offer Details

CompanyNeurowyzr
RoleLead Frontend Engineer (Remote)
Fixed Salaryโ‚น35 LPA
Variable Bonusโ‚น1 LPA
Joining Bonusโ‚น1 LPA
Retention Bonusโ‚น0
ESOPs~6,000โ€“8,000 units (valued ~$5โ€“6/unit, strike price ~$3)

  • Vesting Period: 4 years (1.5 years cliff)
  • Equity Value (approximate): $30,000 - $40,000

โŒ Why I Declined the Offer?

  • Stability: Still in very early growth phase, more risky compared to my other offers.
  • Longer Vesting: 1.5 years cliff on ESOPs means no ownership till 1.5 years โ€” a bit risky in startups.
  • Workload: Expected to own a large chunk of the frontend alone initially (common in startups, but heavier compared to MNCs).

Thought:
Although the Neurowyzr offer was competitive and the discussions were great, I had slightly better options aligned with my long-term goals. ๐Ÿš€
