There are now three major camps:
1. Directed evolution
Seamless Therapeutics
Brink Therapeutics
Strengths:
grounded in experimental biology
proven path
Weakness:
slower scaling
2. AI-designed
Profluent
Basecamp
Strengths:
massive search space
potentially leapfrog biology
Weakness:
still depends on experimental validation
3. Hybrid engineering
Stylus Medicine
Strengths:
combines directed evolution, structural modelling, and ML/AI
Weakness:
complexity
Where does this leave Sangamo? Sangamo's MINT platform is based on Bxb1 recombinase engineering. It uses structural modelling, directed evolution and modular recombination.
But compared to this new landscape, the MINT platform looks to be slower, has narrower tech breadth, the funding is weak, and partners are declining.
Now with two partnerships the (uncomfortable) conclusion that Lilly - one of the most aggressive pharma companies right now - has validated recombinases, committed billions, but not chosen Sangamo. While that doesn't automatically mean Sangamo's tech is bad, it (strongly) suggests the market believes newer platforms may have higher ceiling and/or better execution potential.
