Which SOMATIC alternative should I choose?

It depends on your size. Efference is the closest match on what SOMATIC actually does. If you need something more established, sort the table by team size — larger teams generally mean more support and a longer track record. If budget is the constraint, the earlier-batch companies are usually the ones still competing on price.

Is SOMATIC still active?

SOMATIC is still operating, so switching is a choice rather than a forced migration. Compare on fit and price rather than urgency.

How was this list put together?

Every company here is Y Combinator-backed and was matched to SOMATIC on what it actually does — its own description of its product — rather than on a broad category label. Batch, team size and operating status come from the YC directory and are shown as-is. We do not rank by payment.
