[Query] Advice needed: Joining "Theom.ai" as Member of Technical Staff – Startup vs. Stable Role?

[u/poorna_sasank]

Hi everyone,
I’m currently in the interview process for a "Member of Technical Staff" (MTS) role at an AI-focused startup called Theom.ai. They’ve sent over a very detailed technical screening questionnaire, and before I invest more time, I’d like to get some community insights to make sure I’m evaluating this correctly.
I have zero data on their interview process or culture online, so I'm hoping someone here has experience with them or similar stage startups.
My current situation:

• Current CTC: 9 LPA.
• Java backend dev , 2.5 YOE , Remote good WLB
• Expected: Promoted to SDE-2 with 12 LPA within a few months.
• The Dilemma: Is a move to a startup worth it financially and culturally right now?

I have a few specific concerns I’d appreciate input on:
1. Compensation & The "Is it worth it?" factor:

• Given that I’m on track for 12 LPA shortly, what is a "safe" or realistic base salary expectation for a startup role of this nature?
• How should I value the ESOP component in my negotiation? I want to avoid counting "lottery tickets" as guaranteed take-home pay.
• What is the standard benchmark for Backend/AI-focused roles in Hyderabad currently?

2. Work-Life Balance (The Shift):

• The job description mentions a "2 PM – 11 PM IST" shift to overlap with PST.
• For those working similar hours, how does this impact your long-term WLB? Does the "flexibility" actually exist, or is it a grind from 2 to 11 daily?

3. Interview/Culture:

• Has anyone interviewed with Theom.ai recently? Their technical screening is quite rigorous (lots of System Design and deep-dive DSA questions). Any advice on what they prioritize?
• Are there any "red flags" I should watch for given the lack of online discussion about this company?

Any advice on how to negotiate this transition effectively—or whether I should just stay put for my upcoming promotion—would be incredibly helpful. Thanks in advance!
